Исследуем возможности ИИ писать код. Часть 1
ОглавлениеОтвет КлодаОтвет КлодаОтвет Клода
ИИ — одна из самых обсуждаемых тем последних лет. Многие считают, что он заменит разработчиков, сделав их ненужными. Я решил проверить, насколько это утверждение правдиво, и провести исследование возможностей ИИ в написании кода.
Эта статья — первая из цикла. В рамках исследования я ставлю перед собой несколько задач:
Проверить, насколько качественный и жизнеспособный код генерирует ИИ.
Разобраться, действительно ли ИИ способен заменить разработчиков и можно ли без технических знаний создать работающее приложение.
Сравнить выдачу нескольких LLM (Anthropic Claude 3.5, OpenAI ChatGPT-4o, OpenAI ChatGPT o1-preview, Deepseek R1) и удобство работы с ними.
Поделиться опытом работы с ИИ, используя различные техники промптинга для получения качественных результатов выдачи.
Методология
В качестве отправной точки будет подготовлен шаблон проекта Spring Boot.
Стек:
Java 17
Spring Boot с JPA
Liquibase, Hibernate, Lombok
Потребуется реализовать приложение, в котором доступны CRUD-операции:
Создание операции (Operation)
Обновление операции (Operation)
Поиск всех операций (Operation)
Поиск операции по ID (Operation)
Удаление операции (Operation) Также необходимо будет написать unit и MVC тесты на небольшой кусок логики.
Каждой модели ИИ будет дан одинаковый начальный промпт. Затем я буду запрашивать реализацию различных частей функционала. Я не буду бесконечно улучшать код: если он нерабочий, я попрошу исправить ошибки, а если рабочий — отмечу возможные улучшения.
Общение с ИИ будет происходить на английском. Когда я работал с Anthropic Claude впервые, он плохо понимал русский язык, из-за чего качество ответов значительно ухудшалось. Поэтому, чтобы условия были одинаковыми, я буду использовать английский для всех моделей.
Итак, первым испытуемым будет Anthropic Claude 3.5 — или просто Клод.
Клод: начало пути
Весь исходный код доступен на GitHub. Как я уже писал ранее, я создал заготовку проекта с помощью Spring Initializr. Именно её я буду наполнять кодом.
Сначала нужно создать промпт для Клода. Он задаст тон общению и повлияет на качество выдачи.
Что важно указать в промпте?
Роль модели и перечень технологий, с которыми она должна работать.
Цель общения — что я хочу от ИИ.
Правила взаимодействия — например, как он должен отвечать и уточнять вопросы.
Первоначальный промпт
You will be acting as a backend developer.
You are have an expertise in the following technologies:
Java 21+, Spring boot, Spring JPA, Hibernate, Lombok, Spring Web, REST API, SQL.
Your goal is to create a production-ready solution for the user and answer
their questions. You should clarify questions to provide the best possible answer.
If you have any questions, ask them first without providing a solution.
Only after all questions have been clarified, you provide a solution for the user.
You should maintain a friendly and professional tone.
Here are some important rules of conduct:
- If you're not sure how to respond, say: "Sorry, I didn't understand you.
Could you please rephrase your question, please?"
- If you don't know the answer to a question, say:
"I am sorry, but I don't know that answer.
Can you please clarify your question for me?"
Here is the user question:
I have already created an application using Spring Initializr with the following dependencies:
Lombok, Spring Web, Spring Data JPA, PostgreSQL Driver, Liquibase Migration.
Write a Liquibase migration for the tables.
<table1>
Category table with columns:
- category_id (bigint),
- category_name (varchar),
- category_description (varchar)
<table1>
<table2>
Operation table with columns:
- operation_id (bigint),
- operation_public_id (varchar),
- operation_name (varchar),
- operation_amount(bigdecimal),
- operation_type (enum),
- category_id (FK to category table)
<table2>
Suggest how to store the operation_type.
In the code, the operation type will be an Enum with the values (DEPOSIT, WITHDRAW).
Think about the answer first before responding. Think step-by-step.Ключевые фразы, улучшающие выдачу
"If you have any questions, ask them first without providing a solution." Эта фраза значительно улучшает ответы модели. Вместо того чтобы сразу выдавать решение, она сначала задаст уточняющие вопросы. Это позволяет добавить детали, которые могли быть упущены.
"Think step-by-step." Фраза заставляет модель лучше продумывать ответ и уменьшает количество ошибок и домыслов.
Помимо базовых инструкций, я также попросил Клода написать миграцию таблиц с использованием Liquibase. Я указал, какие колонки мне нужны, и попросил предложить вариант хранения типов операций.
Промпт готов, первый вопрос задан. Отправляем его Клоду и ждём ответа.
Ответ КлодаLet me analyze your requirements:
Database Structure:
Two tables: Category and Operation
Category is the parent table with a primary key referenced by Operation
Operation has an enum field operation_type
Questions for clarification:
Should category_id in both tables be auto-incrementing?
What should be the maximum lengths for varchar fields (category_name, category_description, operation_public_id, operation_name)?
Should any of these fields be nullable?
For operation_amount, how many digits before and after decimal point do you need?
Should operation_public_id be unique?
Before I provide the Liquibase migration script, please answer these questions so I can create the most appropriate solution for your needs.
Regarding the operation_type storage, I suggest two approaches:
As a VARCHAR field with a check constraint limiting values to 'DEPOSIT' and 'WITHDRAW'
As a custom ENUM type in PostgreSQL
The first approach is generally more flexible for future modifications and better portable across different databases. Would you like me to proceed with this approach, or would you prefer the PostgreSQL ENUM type?
Please provide your preferences so I can create a complete migration script.
Именно поэтому важно давать правильные инструкции. Клод не стал сразу выдавать решение, а уточнил детали. Он проговорил, что ему требуется сделать, и задал вопросы по структуре таблиц (некоторые детали я специально не указывал). Это хороший знак: теперь я могу рассчитывать на корректную миграцию.
Кроме того, Клод предложил несколько вариантов хранения operation_type и объяснил, какой из них предпочитает и почему.
Отвечаем на вопросы Клода и ждём финальный вариант миграции.
1. Correct
2. Questions for clarification:
1. Yes, category_id and operation_id should be auto-incremented
2. For category_name, operation_public_id and operation_name - varchar(255), and for category_description (varchar 1000)
3. Nullable fields: category_name
4. 20 digits before decimal point and 2 after
5. Yes
Regarding the operation_type, let's take the first approach.Ошибки, исправления и первый Pull Request
Ответ КлодаThank you for the clarification. I'll create a Liquibase migration script that meets all these requirements.

</databaseChangeLog>После уточнения деталей он выдал код миграции, но в формате XML. Ни я, ни он не уточнили, в каком формате нужен результат, поэтому я попросил его переделать миграцию используя YAML.
Could you re-write the migration using YAML instead of XML?Here's the equivalent Liquibase migration using YAML format:

Клод не добавил миграцию в databaseChangelogMaster (и даже не создал этот файл). Ну, с кем не бывает. Я тоже допустил ошибку в промпте: Клод сделал category_name nullable, а надо было category_description. Исправлять это я буду вручную.
Я хвалил Клода за уточняющие вопросы перед генерацией миграции, но, кажется, он мог запросить уточняющую информацию о планируемой работе с данными, что могло бы позволить заранее настроить индексы. Однако он этого не сделал, а я, в рамках эксперимента, решил "не знать" об индексах и игнорировать этот момент.
Настраиваем соединение с БД
Миграция готова, но прежде чем её запустить, нужно настроить соединение с базой данных. Просим Клода помочь.
Write the configuration to connect the application to the PostgreSQL database.I'll help you configure the database connection. Let me write the configuration for both development and production environments using YAML format.
# src/main/resources/application.yml
spring:
datasource:
url: jdbc:postgresql://localhost:5432/your_database_name
username: your_username
password: your_password
driver-class-name: org.postgresql.Driver
jpa:
hibernate:
ddl-auto: validate # validates the schema, makes no changes to the database
show-sql: false # set to true if you want to see SQL queries in logs
properties:
hibernate:
dialect: org.hibernate.dialect.PostgreSQLDialect
format_sql: true # formats SQL queries in logs if show-sql is true
liquibase:
change-log: classpath:db/changelog/db.changelog-master.yaml
enabled: true # enables Liquibase auto-deployment of changes
# Connection pool properties (using HikariCP - Spring Boot default)
hikari:
minimum-idle: 5
maximum-pool-size: 20
idle-timeout: 300000 # 5 minutes
pool-name: HikariPool
max-lifetime: 1200000 # 20 minutes
connection-timeout: 20000 # 20 secondsFor different environments, you can create separate configuration files:
# src/main/resources/application-dev.yml
spring:
datasource:
url: jdbc:postgresql://localhost:5432/dev_database
username: dev_user
password: dev_password
jpa:
show-sql: true
# src/main/resources/application-prod.yml
spring:
datasource:
url: jdbc:postgresql://${DB_HOST}:${DB_PORT}/${DB_NAME}
username: ${DB_USERNAME}
password: ${DB_PASSWORD}
jpa:
show-sql: falseКлод предложил настроить несколько профилей, что, возможно, избыточно на старте, но полезно для production-ready кода. Также он добавил базовый connection-pool и дал рекомендации по настройке продового окружения.
Но не обошлось без проблем: Клод неправильно объявил connection-pool в application.yaml, из-за чего Hikari не заработает. Ошибка не критическая, но и неочевидная — Spring просто выдаст предупреждение в логе при запуске. Такие баги самые неприятные, потому что они не приводят к явному падению, но могут сказаться на работе приложения позже.
Вывод: Всегда проверяйте настройки, предложенные ИИ. Он не гарантирует работоспособность кода.
Правильный вариант:
spring:
datasource:
url: jdbc:postgresql://localhost:5432/anthropic_claude?currentSchema=anthropic_claude
username: anthropic_claude_app
password: strongPassword
driver-class-name: org.postgresql.Driver
# Connection pool properties (using HikariCP - Spring Boot default)
hikari:
minimum-idle: 5
maximum-pool-size: 20
idle-timeout: 300000 # 5 minutes
pool-name: HikariPool
max-lifetime: 1200000 # 20 minutes
connection-timeout: 20000 # 20 secondsСоздаём init.sql и поднимаем БД в Docker
Следующий шаг — создание init.sql для удобства локальной разработки. Я попросил Клода создать файл с настройкой прав доступа.
Write init.sql with the following information:
- Create an "app" role with a login password of 'strongPassword'.
- Create a schema "my_app_schema" and authorize the "app" role to use it.
- Grant all privileges to the "app" role on the "my_app_schema"Here's the init.sql script that sets up the database role, schema, and permissions:
-- Create role with login capability
CREATE ROLE app WITH
LOGIN
PASSWORD 'strongPassword'
NOSUPERUSER
INHERIT
NOCREATEDB
NOCREATEROLE
NOREPLICATION;
-- Create schema
CREATE SCHEMA my_app_schema;
-- Grant usage on schema to app role
GRANT USAGE ON SCHEMA my_app_schema TO app;
-- Grant all privileges on all tables in schema to app role
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA my_app_schema TO app;
-- Grant all privileges on all sequences in schema to app role
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA my_app_schema TO app;
-- Make sure new tables and sequences will be accessible by app role
ALTER DEFAULT PRIVILEGES IN SCHEMA my_app_schema
GRANT ALL PRIVILEGES ON TABLES TO app;
ALTER DEFAULT PRIVILEGES IN SCHEMA my_app_schema
GRANT ALL PRIVILEGES ON SEQUENCES TO app;
-- Set search path for the app role
ALTER ROLE app SET search_path TO my_app_schema;Now you should update your application.yml to use this schema:
spring:
datasource:
url: jdbc:postgresql://localhost:5432/your_database_name?currentSchema=my_app_schema
username: app
password: strongPasswordКлод сделал всё правильно: создал ограниченную роль для приложения и напомнил, что нужно обновить application.yaml. Это приятно.
Теперь нужно поднять PostgreSQL в Docker. Я решил не тратить время и написал docker-compose.yaml вручную:
version: '3.1'
services:
anthropic-claude-db:
container_name: anthropic-claude-postgres
image: postgres:15
restart: always
environment:
POSTGRES_USER: anthropic_claude_user
POSTGRES_PASSWORD: strongUserPassword
POSTGRES_DB: anthropic_claude
volumes:
- ./db-volume:/var/lib/postgresql
- ./init.sql:/docker-entrypoint-initdb.d/init.sql
ports:
- "5432:5432"Попробуем запустить.
Первая серьёзная ошибка
Ожидаемо, Liquibase не смог найти db.changelog-master.yaml (Liquibase failed to start because no changelog could be found at 'classpath:/db/changelog/db.changelog-master.yaml). Почему? Потому что Клод забыл его создать. Пишу ему об этом и прошу исправить.
When I start the application, I get an error.
Liquibase failed to start because no changelog could be found at
'classpath:/db/changelog/db.changelog-master.yaml'.You need to create the changelog directory structure and the master changelog file. Here's what you need to do:
Create the following directory structure in your project:
src/
└── main/
└── resources/
└── db/
└── changelog/
├── db.changelog-master.yaml
└── changes/
└── 001-initial-schema.yamlCreate the master changelog file (db.changelog-master.yaml):
databaseChangeLog:
- include:
file: changes/001-initial-schema.yaml
relativeToChangelogFile: trueMove the migration we created earlier into 001-initial-schema.yaml under the changes directory.
Here's the full command sequence if you're using a Unix-like system:
mkdir -p src/main/resources/db/changelog/changes
touch src/main/resources/db/changelog/db.changelog-master.yaml
touch src/main/resources/db/changelog/changes/001-initial-schema.yamlAfter creating these files and directories:
Put the master changelog content into
db.changelog-master.yamlPut the table creation changelog we created earlier into
001-initial-schema.yaml
Now when you start the application, Liquibase should be able to find and execute your changelog files.
Клод добавил db.changelog-master.yaml файл и даже предложил структуру хранения миграций. Однако теперь возникла новая проблема — ошибка доступа к схеме.
Клод начинает "мудрить"
Пытаемся вместе с Клодом решить эту проблему.
Ответ КлодаI've added a changelog to the master file, but when I run the application, a new error occurs: permission denied for schema anthropic_claude
This error means the 'app' role doesn't have sufficient permissions on the schema. Let's fix the permissions by running additional SQL commands as a superuser (postgres):
-- Connect as superuser (postgres) and run these commands:
-- Make sure the role and schema exist
CREATE ROLE app WITH LOGIN PASSWORD 'strongPassword' NOSUPERUSER INHERIT NOCREATEDB NOCREATEROLE NOREPLICATION;
CREATE SCHEMA IF NOT EXISTS my_app_schema;
-- Grant all necessary permissions
GRANT ALL ON SCHEMA my_app_schema TO app;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA my_app_schema TO app;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA my_app_schema TO app;
-- This is important for Liquibase to be able to create new tables
ALTER DEFAULT PRIVILEGES IN SCHEMA my_app_schema GRANT ALL ON TABLES TO app;
ALTER DEFAULT PRIVILEGES IN SCHEMA my_app_schema GRANT ALL ON SEQUENCES TO app;
-- Make app the owner of the schema (optional, but can help avoid permission issues)
ALTER SCHEMA my_app_schema OWNER TO app;
-- Set the search path
SET search_path TO my_app_schema;
ALTER ROLE app SET search_path TO my_app_schema;You can run these commands using psql or your preferred PostgreSQL client tool:
psql -U postgres -d your_database_name -f permissions.sqlAfter running these commands, restart your application and the permission error should be resolved.
Я уже не раз встречался с таким поведением: если LLM сталкивается с несколькими ошибками подряд, он начинает "фантазировать" и предлагать плохие решения. Причём каждое следующее исправление бывает хуже предыдущего. Это типичная проблема всех LLM — они не анализируют историю взаимодействия глобально, а просто пытаются найти ближайшее возможное исправление. Иногда каждое следующее исправление хуже предыдущего. В таких случаях лучше остановиться, пересмотреть ситуацию вручную и задать более конкретные инструкции.
Его предложенное исправление оказалось неверным. Я не стал его мучить и просто добавил фикс вручную:
CREATE SCHEMA my_schema_app AUTHORIZATION app;После этого приложение запустилось без проблем.
Какие можно сделать выводы?
Чем больше ошибок, тем хуже становится выдача. LLM не анализирует всю историю взаимодействий, а просто пытается угадать следующее исправление.
Проверяйте настройки инфраструктуры. Ошибки могут быть незаметными, но критичными.
Первый ПР готов
https://github.com/nzinovev/anthropic-claude/pull/1
Создаём сущности
Приложение успешно запускается, таблицы созданы, миграции накатываются. Следующий шаг — создать сущности.
Кроме того, я попросил Клода предложить структуру пакетов, чтобы понимать, где хранить код.
Write entities for operation and category tables.
Provide a path to the package where I should create the entities.Create these entities in the src/main/java/com/yourcompany/domain/entity package. Here are the entities:
// src/main/java/com/yourcompany/domain/entity/Category.java
package com.yourcompany.domain.entity;
import jakarta.persistence.*;
import lombok.Getter;
import lombok.Setter;
import java.util.Set;
@Entity
@Table(name = "category", schema = "my_app_schema")
@Getter
@Setter
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "name", nullable = false)
private String name;
@OneToMany(mappedBy = "category")
private Set operations;
}
// src/main/java/com/yourcompany/domain/entity/Operation.java
package com.yourcompany.domain.entity;
import jakarta.persistence.*;
import lombok.Getter;
import lombok.Setter;
import java.math.BigDecimal;
import java.time.LocalDateTime;
@Entity
@Table(name = "operation", schema = "my_app_schema")
@Getter
@Setter
public class Operation {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "operation_type", nullable = false)
@Enumerated(EnumType.STRING)
private OperationType operationType;
@Column(name = "amount", nullable = false)
private BigDecimal amount;
@Column(name = "description")
private String description;
@Column(name = "operation_date", nullable = false)
private LocalDateTime operationDate;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "category_id", nullable = false)
private Category category;
}
// src/main/java/com/yourcompany/domain/entity/OperationType.java
package com.yourcompany.domain.entity;
public enum OperationType {
DEPOSIT,
WITHDRAW
}
Make sure you have the following dependencies in your pom.xml:
org.projectlombok
lombok
true
org.springframework.boot
spring-boot-starter-data-jpa
Directory structure should look like this:
src/
└── main/
└── java/
└── com/
└── yourcompany/
└── domain/
└── entity/
├── Category.java
├── Operation.java
└── OperationType.java
Ошибки в генерации сущностей
Первое, что заметил — Клод начал терять контекст:
В
Categoryпропало полеdescription.В
Operationнеожиданно появилосьoperationDate.Он изменил названия колонок, из-за чего приложение перестало запускаться.
Пришлось вручную исправлять названия колонок. Далее буду добавлять недостающую информацию в контекст, чтобы избежать таких ошибок.
Проблема с equals() & hashCode()
Ещё одна ошибка — не переопределены equals() и hashCode().
Клод использует Set для Operation, что без корректного equals() может привести к дублированию одинаковых объектов с разными ссылками.
Я попросил его переопределить equals() и hashCode(), чтобы проверить, не добавит ли он в эти методы объекты OneToMany / ManyToOne и не создаст ли циклическую зависимость (что может привести к OutOfMemory).
Почему важно переопределять equals() и hashCode()?
Если этого не делать, объекты сравниваются по ссылке, что может привести к багам.
Lombok-аннотации
@EqualsAndHashCodeи@Dataнеявно переопределяют эти методы используя все имеющиеся свойства класса (например, могут учитывать связанные сущности, что приведёт к рекурсии).Лучший вариант — переопределять вручную.
Прошу переопределить equals() & hashCode()
Override equals and hashCode for Category and Operation entites.Here are the updated entities with equals and hashCode methods:
// src/main/java/com/yourcompany/domain/entity/Category.java
package com.yourcompany.domain.entity;
import jakarta.persistence.*;
import lombok.Getter;
import lombok.Setter;
import java.util.Set;
import java.util.Objects;
@Entity
@Table(name = "category", schema = "my_app_schema")
@Getter
@Setter
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "name", nullable = false)
private String name;
@OneToMany(mappedBy = "category")
private Set operations;
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Category category = (Category) o;
if (id == null || category.id == null) return false;
return Objects.equals(id, category.id);
}
@Override
public int hashCode() {
return id != null ? id.hashCode() : 0;
}
}
// src/main/java/com/yourcompany/domain/entity/Operation.java
package com.yourcompany.domain.entity;
import jakarta.persistence.*;
import lombok.Getter;
import lombok.Setter;
import java.math.BigDecimal;
import java.time.LocalDateTime;
import java.util.Objects;
@Entity
@Table(name = "operation", schema = "my_app_schema")
@Getter
@Setter
public class Operation {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "operation_type", nullable = false)
@Enumerated(EnumType.STRING)
private OperationType operationType;
@Column(name = "amount", nullable = false)
private BigDecimal amount;
@Column(name = "description")
private String description;
@Column(name = "operation_date", nullable = false)
private LocalDateTime operationDate;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "category_id", nullable = false)
private Category category;
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Operation operation = (Operation) o;
if (id == null || operation.id == null) return false;
return Objects.equals(id, operation.id);
}
@Override
public int hashCode() {
return id != null ? id.hashCode() : 0;
}
}
I've implemented equals and hashCode methods using the database identifier (id) field only. This is a common practice for JPA entities because:
It provides consistent behavior with database identity
It avoids issues with lazy loading
It works well with collections and hibernate's first-level cache
It prevents infinite recursion with bidirectional relationships
Note that the implementation:
Returns false if either object's ID is null
Only compares IDs when both objects are non-null and of the same class
Uses the ID field for hashCode calculation
Ошибки в реализации equals() и hashCode()
Клод почти справился, но есть нюансы:
Он избежал циклической зависимости и учёл ленивые загрузки. Однако есть две проблемы:
Использование
hashCode = 0дляid = null, что может снизить производительностьHashSetиHashMap, если там будет множество объектов сhashCode = 0.Проверка классов через
getClass(), т.к. в проекте используется Hibernate, сущности будут использоваться в прокси-объектах, следовательно, данный вызов может некорректно отрабатывать. Лучше использовать instanceof.
Исправленный вариант equals() и hashCode()
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof Category category)) return false; // Лучше, чем getClass() для прокси объектов
return id != null && id.equals(category.id); // Без дополнительной проверки id == null
}
@Override
public int hashCode() {
return id != null ? id.hashCode() : super.hashCode(); // Использование super.hashCode() для уникальности несохранённых объектов

Ошибка с EAGER-загрузкой
Клод также по умолчанию сделал EAGER-связь между Category и Operation. На данном этапе это избыточно. Лучше следовать правилу: "Всегда LAZY, если нет необходимости в EAGER".

Сущности готовы, следующий этап — создание CRUD-операций.
Пробуем CRUD. Часть 1 (неудачно)
Я рискнул и попросил Клода сразу создать полный цикл для операции CREATE – контроллер → сервис → DAO. Если всё пройдёт гладко, таким же способом реализую и остальные операции (READ, UPDATE, DELETE).
Я не уточнял, какую DTO использовать на вход и выход, чтобы проверить, поймёт ли это Клод самостоятельно или будет работать с сущностями в контроллере.
Чтобы избежать усложнения задачи, я сразу уточнил, что валидация полей не нужна – иначе Клод может потерять фокус и ухудшить качество выдачи.
Ошибка в промпте: мы с Клодом не поняли друг друга
Write a logic for the Operation entity (Controller - Service - DAO).
In the first iteration, skip validation of all fields.Что пошло не так? Практически всё.
Я не добавил слово CREATE, а Клод не стал уточнять детали.
В результате он сгенерировал весь CRUD (включая READ, UPDATE, DELETE) – с ошибками.
Исправлять этот код дальше будет неудобно. Легче делать всё шаг за шагом. Именно поэтому я просил Клода не добавлять валидацию – чтобы не перегружать контекст.
Придётся очистить контекст и перезапустить задачу. Покажу, как это сделать без потери истории.
Но сначала разберём ошибки в коде.

Что Клод сделал хорошо:
Корректно расставил
@Transactional– разделилreadOnly-транзакции и полноценные.Добавил DTO – не вернул наружу сущность.
Указал структуру проекта – значит, часть контекста сохранилась.
Предложил дальнейшие шаги.
Что Клод сделал плохо:
Сущность "просочилась" в контроллер – маппинг в DTO происходит на уровне контроллера (вне транзакции), что может вызвать
LazyInitializationException.Сейчас ошибки не будет (мы берём только
idкатегории), но это ещё хуже – создаётся ложное ощущение, что всё работает правильно.
Не уточнил, какие поля должны быть в DTO.
Из-за этого он вытянул
categoryIdнаружу, хотя это не критично.
Ошибся с
@Transactional.Я явно указал DAO-слой, но Клод повесил
@Transactionalна сервис.Это проблема, потому что бизнес-логика (сервис) может вызывать сторонние API – и в таком варианте всё это будет выполняться внутри транзакции, что неэффективно.
Можно ли исправить эти ошибки позднее? Конечно. Но если сделать сразу правильно, это сэкономит много времени в будущем.
Почему я очищаю контекст
Когда LLM изменяет большой кусок кода, он часто редактирует даже те части, которые не нужно трогать.
Это приводит к:
"Захламлению" контекста
Порче логики даже в тех местах, где её не нужно менять
Ухудшению качества последующих ответов
Поэтому проще очистить контекст и задать задачу заново. Я задам новый промпт и поправлю выдачу Клода, чтобы избежать ошибок.
Этот подход показывает, что важно разбивать сложные задачи на этапы.
Очистка контекста – полезный инструмент, если модель начала терять логику.
Дальше попробую создать CREATE-операцию по шагам, чтобы минимизировать ошибки.
Пробуем CRUD. Часть 2
Отчищаем контекст и задаём промпт с историей

Скрытый текстYou will be acting as a backend developer. You are have an expertise in the following technologies: Java 21+, Spring boot, Spring JPA, Hibernate, Lombok, Spring Web, REST API, SQL. Your goal is to create a production-ready solution for the user and answer their questions. You should clarify questions to provide the best possible answer. If you have any questions, ask them first without providing a solution. Only after all questions have been clarified, you provide a solution for the user.
You should maintain a friendly and professional tone.
Here are some important rules of conduct:
- If you're not sure how to respond, say: "Sorry, I didn't understand you. Could you please rephrase your question, please?"
- If you don't know the answer to a question, say: "I am sorry, but I don't know that answer. Can you please clarify your question for me?"
Here is the history (between you and user) before the question:
<history>
user: "I have already created an application using Spring Initializr with the following dependencies: Lombok, Spring Web, Spring Data JPA, PostgreSQL Driver, Liquibase Migration. Write a Liquibase migration for the tables.<table1>
Category table with columns: category_id (bigint), category_name (varchar), category_description (varchar)</table1><table2>
Operation table with columns: operation_id (bigint), operation_public_id (varchar), operation_name (varchar), operation_amount(bigdecimal), operation_type (enum), category_id (FK to category table)
</table2>
Suggest how to store the operation_type. In the code, the operation type will be an Enum with the values (DEPOSIT, WITHDRAW)."
You: "Let me analyze your requirements:
Database Structure:
Two tables: Category and Operation
Category is the parent table with a primary key referenced by Operation
Operation has an enum field operation_type
Questions for clarification:
Should category_id in both tables be auto-incrementing?
What should be the maximum lengths for varchar fields (category_name, category_description, operation_public_id, operation_name)?
Should any of these fields be nullable?
For operation_amount, how many digits before and after decimal point do you need?
Should operation_public_id be unique?
Before I provide the Liquibase migration script, please answer these questions so I can create the most appropriate solution for your needs.
Regarding the operation_type storage, I suggest two approaches:
As a VARCHAR field with a check constraint limiting values to 'DEPOSIT' and 'WITHDRAW'
As a custom ENUM type in PostgreSQL
The first approach is generally more flexible for future modifications and better portable across different databases. Would you like me to proceed with this approach, or would you prefer the PostgreSQL ENUM type?
Please provide your preferences so I can create a complete migration script."
user: "1. Correct
Questions for clarification:
Yes, category_id and operation_id should be auto-incremented
For category_name, operation_public_id and operation_name - varchar(255), and for category_description (varchar 1000)
Nullable fields: category_description
20 digits before decimal point and 2 after
Yes
Regarding the operation_type, let's take the first approach."
you: "Thank you for the clarification. I'll create a Liquibase migration script that meets all these requirements.

Think about the answer first before responding. Think step-by-step.
Пришлось два раза переписывать промпт — из-за ошибок в формулировке.
В первый раз Клод уточнял детали, и код получился чуть качественнее, но здесь я разберу второй вариант, так как именно он был отправлен в работу.
Сброс контекста и обновление промпта помогают ИИ вспомнить начальные установки.
Это один из способов повысить точность ответа, но у него есть минус — такой подход требует больше времени, так как приходится собирать историю общения с моделью (тег <history> в промпте).
Я советую использовать теги <history></history> только в двух случаях:
ИИ зашёл в тупик и выдаёт некорректные решения.
Были ошибки в промпте и хочется избавиться от ошибок.
Преимущество этого метода — возможность редактировать историю общения, а также восстановление изначальных требований по взаимодействию модели с пользователем, что в конечном счёте улучшает итоговый результат.

Что получилось лучше по сравнению с первой попыткой
Ограничение задачи позволило Клоду улучшить качество кода:
Теперь сервис не возвращает сущность в контроллер.
Код стал чище, а выдача качественнее.
Добавлены простейшие бизнес-обработки.
Но не обошлось без недостатков - Нет @JsonProperty в DTO. Наличие этой аннотации делает безопасным изменения полей DTO в коде без влияния на API-контракт.
Тестируем работоспособность
Отправляем запрос:
{
"name": "Заправка",
"amount": 125.23,
"type": "WITHDRAW",
"categoryId": 1
}
Получаем ответ:
{
"publicId":"31cf0666-38b6-4aa3-9c6d-2547fe15e237",
"name":"Заправка",
"amount":125.23,
"type":"WITHDRAW",
"categoryId":1
}
Выбираем стратегию для остальных CRUD-операций
Я попробовал два подхода:
Создание всех CRUD-операций сразу.
Создание каждой операции по отдельности.
Второй вариант оказался качественнее, поэтому по нему будут реализованы READ, UPDATE, DELETE.
PR на создание операции

Реализуем UPDATE-логику для операций
Write an UPDATE logic for the Operation entity (Controller - Service - DAO).

Update only provided fields
Return updated operation

// Add this method to the existing OperationController class

}
Now you can update an operation by making a PUT request to /api/v1/operations/{publicId} with a JSON body containing the fields you want to update. For example:
{
"name": "Updated Operation Name",
"amount": 150.00,
"type": "DEPOSIT",
"categoryId": 2
}
OperationMapper.updateEntityFromDto — что это вообще?
Клод добавил какую-то странную конструкцию:
operationMapper.updateEntityFromDto(operation, dto);Звучит логично, но есть несколько проблем:
Вынес в маппер логику, которая к нему не относится.
Разделил её по разным слоям: три параметра проставляются в маппере, а один — в сервисе.
Это плохой дизайн, потому что маппер должен просто преобразовывать DTO в сущность и обратно, а не вносить изменения в объект.
OperationNotFoundException, но... не совсем
Клод добавил кастомное исключение:
public class OperationNotFoundException extends RuntimeException { ... }На первый взгляд, всё правильно, но есть один нюанс — он его нигде не использует!
Там, где должно было бросаться OperationNotFoundException, Клод выбрасывает обычный RuntimeException. В итоге, хорошая идея, но не реализованная до конца.
Проблема с обработкой NotFound ошибок
Далее будут появятся другие исключения в том же стиле (например CategoryNotFoundException). В итоге каждое исключение будет уникальным — это усложнит поддержку. Лучше сделать одно NotFoundException, а при необходимости — наследовать от него:
public class NotFoundException extends RuntimeException {
public NotFoundException(String message) {
super(message);
}
}А затем:
public class OperationNotFoundException extends NotFoundException {
public OperationNotFoundException() {
super("Operation not found");
}
}Такой подход даёт два преимущества:
Единый
ExceptionHandler– можно обрабатыватьNotFoundException, а не кучу отдельных классов.Чище код – если появится новый тип
NotFound, его не нужно будет добавлять в обработчик.
Несмотря на эти проблемы, Клод справился с задачей. Код рабочий, даже был предложен тестовый JSON для проверки.
Теперь переходим к поиску операций (READ).
PR на обновление операции
https://github.com/nzinovev/anthropic-claude/pull/6
Реализуем READ-логику для операций
Попросил Клода создать два эндпоинта:
Получение всех операций с пагинацией.
Поиск операции по publicId.
Write a FIND logic for the Operation entity (Controller - Service - DAO).
In the first iteration, skip validation of all fields.
You need to add two endpoints, the first one that finds all operations with pagination,
and the second one that finds an operation by publicId.Let me design the FIND logic step by step:
Components needed:
Controller endpoints for GET requests (findAll with pagination and findByPublicId)
Service methods for both operations
Repository method for finding by publicId (already exists)
DTO for pagination criteria (optional parameters like page, size, sort)
Flow:
Accept pagination parameters
Convert Page to Page
Return paginated response or single operation
Here's the implementation:
// src/main/java/com/yourcompany/dto/PageResponse.java
package com.yourcompany.dto;
import lombok.Data;
import org.springframework.data.domain.Page;
import java.util.List;
@Data
public class PageResponse {
private List content;
private int pageNumber;
private int pageSize;
private long totalElements;
private int totalPages;
private boolean last;
public static PageResponse from(Page page) {
PageResponse response = new PageResponse<>();
response.setContent(page.getContent());
response.setPageNumber(page.getNumber());
response.setPageSize(page.getSize());
response.setTotalElements(page.getTotalElements());
response.setTotalPages(page.getTotalPages());
response.setLast(page.isLast());
return response;
}
}
// src/main/java/com/yourcompany/service/OperationService.java
// Add these methods to the existing OperationService class
package com.yourcompany.service;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
@Service
@RequiredArgsConstructor
public class OperationService {
// ... existing methods ...
@Transactional(readOnly = true)
public PageResponse findAll(Pageable pageable) {
Page operationPage = operationRepository.findAll(pageable);
Page responsePage = operationPage.map(operationMapper::toDto);
return PageResponse.from(responsePage);
}
@Transactional(readOnly = true)
public OperationResponse findByPublicId(String publicId) {
Operation operation = operationRepository.findByPublicId(publicId)
.orElseThrow(() -> new OperationNotFoundException(
String.format("Operation with publicId %s not found", publicId)));
return operationMapper.toDto(operation);
}
}
// src/main/java/com/yourcompany/controller/OperationController.java
// Add these methods to the existing OperationController class
package com.yourcompany.controller;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Sort;
@RestController
@RequestMapping("/api/v1/operations")
@RequiredArgsConstructor
public class OperationController {
// ... existing methods ...
@GetMapping
public PageResponse findAll(
@RequestParam(defaultValue = "0") int page,
@RequestParam(defaultValue = "20") int size,
@RequestParam(defaultValue = "operation_id") String sortBy,
@RequestParam(defaultValue = "DESC") Sort.Direction direction) {
PageRequest pageRequest = PageRequest.of(
page,
size,
Sort.by(direction, sortBy)
);
return operationService.findAll(pageRequest);
}
@GetMapping("/{publicId}")
public OperationResponse findByPublicId(@PathVariable String publicId) {
return operationService.findByPublicId(publicId);
}
}
Now you can:
Get a paginated list of operations:
GET /api/v1/operations?page=0&size=20&sortBy=operation_id&direction=DESC
Response example:
{
"content": [
{
"publicId": "550e8400-e29b-41d4-a716-446655440000",
"name": "Operation 1",
"amount": 100.00,
"type": "DEPOSIT",
"categoryId": 1
},
// ... more operations
],
"pageNumber": 0,
"pageSize": 20,
"totalElements": 100,
"totalPages": 5,
"last": false
}
Get a single operation by publicId:
GET /api/v1/operations/550e8400-e29b-41d4-a716-446655440000
Response example:
{
"publicId": "550e8400-e29b-41d4-a716-446655440000",
"name": "Operation 1",
"amount": 100.00,
"type": "DEPOSIT",
"categoryId": 1
}
Как Клод реализовал задачу?
Клод использовал пагинацию Spring JPA, что логично, так как мы работаем с Hibernate.
Код получился почти идеальным:
PageResponseсделан дженериком – можно переиспользовать для любых ответов.Контекст сохраняется – Клод не дублирует уже написанный код.
Минусы реализации
Проблема с sortBy — Клод ссылается на колонку в БД, а не на поле сущности. В таком виде сортировка не будет работать, т.к. JPA для сортировки использует именно название полей сущности.
Spring Data JPA использует рефлексию для работы с сущностями. Когда мы передаем параметр сортировки sortBy, Spring Data JPA пытается найти соответствующее поле по имени внутри класса сущности. JPA ищет свойство (field) внутри Java-класса Operation, а не колонку в базе данных.
Исправляем и переходим к DELETE.
PR на поиск операций
https://github.com/nzinovev/anthropic-claude/pull/7
DELETE – логика для операций
Финальная часть CRUD-операций – удаление. Прошу Клода написать эндпоинт, который удаляет операцию по publicId.
Write a DELETE logic for the Operation entity (Controller - Service - DAO).
In the first iteration, skip validation of all fields.Let me design the DELETE logic step by step:
Components needed:
Controller endpoint for DELETE request
Service method for delete operation
Repository method (will use existing findByPublicId)
Flow:
Find operation by publicId
Delete operation if exists
Return appropriate response status
Here's the implementation:
// src/main/java/com/yourcompany/service/OperationService.java
// Add this method to the existing OperationService class
package com.yourcompany.service;
@Service
@RequiredArgsConstructor
public class OperationService {
// ... existing methods ...
@Transactional
public void deleteOperation(String publicId) {
Operation operation = operationRepository.findByPublicId(publicId)
.orElseThrow(() -> new OperationNotFoundException(
String.format("Operation with publicId %s not found", publicId)));
operationRepository.delete(operation);
}
}
// src/main/java/com/yourcompany/controller/OperationController.java
// Add this method to the existing OperationController class
package com.yourcompany.controller;
@RestController
@RequestMapping("/api/v1/operations")
@RequiredArgsConstructor
public class OperationController {
// ... existing methods ...
@DeleteMapping("/{publicId}")
@ResponseStatus(HttpStatus.NO_CONTENT)
public void deleteOperation(@PathVariable String publicId) {
operationService.deleteOperation(publicId);
}
}
Now you can delete an operation by making a DELETE request to:
DELETE /api/v1/operations/{publicId}Результат
Клод справился без проблем – здесь всё очевидно, комментировать особо нечего.
PR на удаление операции
https://github.com/nzinovev/anthropic-claude/pull/8
Добавляем валидацию
CRUD для operation готов, но пока он довольно примитивен. Кроме того, у нас вообще нет тестов – а это важная часть качественной разработки. Чтобы не растягивать статью, я не буду покрывать тестами и валидацией все эндпоинты.
Я выберу один – CREATE Operation – и попрошу Клода добавить:
Валидацию запроса
Unit-тесты для сервисного слоя
MVC-тест для контроллера
Погнали!
Добавляем валидацию для CREATE-операции
Напоминаю Клоду, как выглядит логика, связанная с созданием операции и прошу добавить валидацию для CREATE-операции.
Запрос КлодуThis is how the "create operation" is implemented at the moment.
<example>
@Data
public class OperationCreateRequest {
private String name;
private BigDecimal amount;
private OperationType type;
private Long categoryId;
}
@RestController
@RequestMapping("/api/v1/operations")
@RequiredArgsConstructor
public class OperationController {
private final OperationService operationService;
@PostMapping
@ResponseStatus(HttpStatus.CREATED)
public OperationResponse createOperation(@RequestBody OperationCreateRequest request) {
return operationService.createOperation(request);
}
}
@Service
@RequiredArgsConstructor
public class OperationService {
private final OperationRepository operationRepository;
private final CategoryRepository categoryRepository;
private final OperationMapper operationMapper;
@Transactional
public OperationResponse createOperation(OperationCreateRequest request) {
Category category = categoryRepository.getReferenceById(request.getCategoryId());
Operation operation = operationMapper.toEntity(request);
operation.setCategory(category);
Operation savedOperation = operationRepository.save(operation);
return operationMapper.toDto(savedOperation);
}
}
@Entity
@Table(name = "operation", schema = "anthropic_claude")
@Getter
@Setter
public class Operation {
@Id
@Column(name = "operation_id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "operation_public_id", nullable = false, unique = true)
private String publicId;
@Column(name = "operation_name", nullable = false)
private String name;
@Column(name = "operation_type", nullable = false)
@Enumerated(EnumType.STRING)
private OperationType type;
@Column(name = "operation_amount", nullable = false)
private BigDecimal amount;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "category_id", nullable = false)
private Category category;
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof Operation operation)) return false;
return id != null && id.equals(operation.id);
}
@Override
public int hashCode() {
return id != null ? id.hashCode() : super.hashCode();
}
}
</example>
Add validation for "create operation" logic.
I'll add validation for the create operation logic. Let's implement it step by step:
Field validations needed:
name: not blank, max length 255
amount: not null, positive
type: not null, valid enum value
categoryId: not null, must exist in database
business rule: category must exist
Changes needed:
Add validation annotations to DTO
Add custom exception classes
Add validation in service layer
Add global exception handler
Here's the implementation:
// src/main/java/com/yourcompany/exception/CategoryNotFoundException.java
package com.yourcompany.exception;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ResponseStatus;
@ResponseStatus(HttpStatus.NOT_FOUND)
public class CategoryNotFoundException extends RuntimeException {
public CategoryNotFoundException(String message) {
super(message);
}
}
// src/main/java/com/yourcompany/exception/ValidationErrorResponse.java
package com.yourcompany.exception;
import lombok.Data;
import java.util.ArrayList;
import java.util.List;
@Data
public class ValidationErrorResponse {
private List errors = new ArrayList<>();
@Data
public static class ValidationError {
private final String field;
private final String message;
}
}
// src/main/java/com/yourcompany/exception/GlobalExceptionHandler.java

public ValidationErrorResponse handleValidationException(MethodArgumentNotValidException ex) {
ValidationErrorResponse response = new ValidationErrorResponse();
ex.getBindingResult().getFieldErrors().forEach(error ->
response.getErrors().add(new ValidationErrorResponse.ValidationError(
error.getField(),
error.getDefaultMessage()
))
);
return response;
}
@ExceptionHandler(CategoryNotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public ValidationErrorResponse handleCategoryNotFoundException(CategoryNotFoundException ex) {
ValidationErrorResponse response = new ValidationErrorResponse();
response.getErrors().add(new ValidationErrorResponse.ValidationError(
"categoryId",
ex.getMessage()
));
return response;
}
}
// src/main/java/com/yourcompany/dto/OperationCreateRequest.java
package com.yourcompany.dto;
import com.yourcompany.domain.entity.OperationType;
import jakarta.validation.constraints.*;
import lombok.Data;
import java.math.BigDecimal;
@Data
public class OperationCreateRequest {
@NotBlank(message = "Operation name is required")
@Size(max = 255, message = "Operation name must not exceed 255 characters")
private String name;
@NotNull(message = "Amount is required")
@Positive(message = "Amount must be positive")
@Digits(integer = 20, fraction = 2, message = "Amount must have at most 20 digits and 2 decimal places")
private BigDecimal amount;
@NotNull(message = "Operation type is required")
private OperationType type;
@NotNull(message = "Category ID is required")
@Positive(message = "Category ID must be positive")
private Long categoryId;
}
// src/main/java/com/yourcompany/service/OperationService.java
@Service
@RequiredArgsConstructor
public class OperationService {
private final OperationRepository operationRepository;
private final CategoryRepository categoryRepository;
private final OperationMapper operationMapper;
@Transactional
public OperationResponse createOperation(OperationCreateRequest request) {
// Check if category exists
Category category = categoryRepository.findById(request.getCategoryId())
.orElseThrow(() -> new CategoryNotFoundException(
String.format("Category with id %d not found", request.getCategoryId())));
Operation operation = operationMapper.toEntity(request);
operation.setCategory(category);
Operation savedOperation = operationRepository.save(operation);
return operationMapper.toDto(savedOperation);
}
}
// src/main/java/com/yourcompany/controller/OperationController.java
@RestController
@RequestMapping("/api/v1/operations")

public class OperationController {
private final OperationService operationService;
@PostMapping
@ResponseStatus(HttpStatus.CREATED)
public OperationResponse createOperation(@Valid @RequestBody OperationCreateRequest request) {
return operationService.createOperation(request);
}
}
Now when creating an operation:
If validation fails, you'll get a 400 Bad Request with details about what went wrong:
{
"errors": [
{
"field": "name",
"message": "Operation name is required"
},
{
"field": "amount",
"message": "Amount must be positive"
}
]
}
If category is not found, you'll get a 404 Not Found:
{
"errors": [
{
"field": "categoryId",
"message": "Category with id 123 not found"
}
]
}
Результат: плюсы и минусы
Клод реализовал грамотную обработку ошибок:
Все ошибки возвращаются сразу – пользователю не нужно отправлять несколько запросов.
Добавлен
ExceptionHandler– обработка ошибок централизована.
Но валидация не работает.
Проблема: отсутствуют зависимости
Клод не добавил нужные зависимости:
<!-- Чтобы заработала аннотация Valid и Spring начал валидацию -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
<!-- Для аннотаций NotBlank, NotNull, etc. -->
<dependency>
<groupId>jakarta.validation</groupId>
<artifactId>jakarta.validation-api</artifactId>
<version>3.1.0</version>
</dependency>Если необходимость jakarta.validation ещё можно догадаться по импорту аннотаций в DTO, то spring-boot-starter-validation менее очевиден.
А я ведь имитирую разработчика с минимальным опытом, и без документации мне сложно понять, почему валидация не работает.
Ошибка с обработкой NotFound-исключений
Как и в CRUD-логике, Клод добавил специфичное исключение:
public class CategoryNotFoundException extends RuntimeException { ... }Такой подход требует:
Создавать отдельное исключение для каждой сущности.
Добавлять его обработку в
ExceptionHandler.
Лучше использовать единое NotFoundException и наследоваться от него (это уже обсуждалось ранее).
Кроме того, добавлена лишняя аннотация:
@ResponseStatus(HttpStatus.NOT_FOUND)Это избыточно, потому что исключение уже обрабатывается глобальным ExceptionHandler.
Попытка исправить – новая проблема
Попросил Клода исправить ошибки:
I've added annotations to OperationCreateRequest.
However, when I send a request with incorrect data,
the application does not respond with a validation error.
The app ignores all annotations relating to validation and passes the request on.The issue is likely because the validation dependencies and configuration are missing. Let's fix this:
First, add the validation dependency to your
pom.xml:
org.springframework.boot
spring-boot-starter-validation
Make sure your application configuration enables validation. Create or update the configuration class:
// src/main/java/com/yourcompany/config/WebConfig.java
package com.yourcompany.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class WebConfig implements WebMvcConfigurer {
// Additional web configuration can be added here if needed
}
Double-check that your controller has the
@Validannotation on the request parameter:
@RestController
@RequestMapping("/api/v1/operations")
@RequiredArgsConstructor
public class OperationController {
private final OperationService operationService;
@PostMapping
@ResponseStatus(HttpStatus.CREATED)
public OperationResponse createOperation(@Valid @RequestBody OperationCreateRequest request) {
return operationService.createOperation(request);
}
}
Verify that your DTO has all the necessary validation annotations:
@Data
public class OperationCreateRequest {
@NotBlank(message = "Operation name is required")
@Size(max = 255, message = "Operation name must not exceed 255 characters")
private String name;
@NotNull(message = "Amount is required")
@Positive(message = "Amount must be positive")
@Digits(integer = 20, fraction = 2, message = "Amount must have at most 20 digits and 2 decimal places")
private BigDecimal amount;
@NotNull(message = "Operation type is required")
private OperationType type;
@NotNull(message = "Category ID is required")
@Positive(message = "Category ID must be positive")
private Long categoryId;
}
Make sure you have the exception handler properly configured:
@RestControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ValidationErrorResponse handleValidationException(MethodArgumentNotValidException ex) {
ValidationErrorResponse response = new ValidationErrorResponse();
ex.getBindingResult().getFieldErrors().forEach(error ->
response.getErrors().add(new ValidationErrorResponse.ValidationError(
error.getField(),
error.getDefaultMessage()
))
);
return response;
}
// Add logging to help with debugging
public GlobalExceptionHandler() {
log.info("GlobalExceptionHandler initialized");
}
@ExceptionHandler(Exception.class)
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public ValidationErrorResponse handleAllUncaughtException(Exception ex) {
log.error("Uncaught exception", ex);
ValidationErrorResponse response = new ValidationErrorResponse();
response.getErrors().add(new ValidationErrorResponse.ValidationError(
"global",
"An unexpected error occurred"
));
return response;
}
}
Test the validation with an invalid request:
curl -X POST http://localhost:8080/api/v1/operations \
-H "Content-Type: application/json" \
-d '{
"name": "",
"amount": -100,
"type": null,
"categoryId": null
}'
You should receive a response like:
{
"errors": [
{
"field": "name",
"message": "Operation name is required"
},
{
"field": "amount",
"message": "Amount must be positive"
},
{
"field": "type",
"message": "Operation type is required"
},
{
"field": "categoryId",
"message": "Category ID is required"
}
]
}
If you're still not seeing validation errors, you can add debug logging to verify the validation is being triggered:
@PostMapping
@ResponseStatus(HttpStatus.CREATED)
public OperationResponse createOperation(@Valid @RequestBody OperationCreateRequest request) {
log.debug("Received operation create request: {}", request);
return operationService.createOperation(request);
}
Also, you can enable debug logging for Spring validation in application.yml:
logging:
level:
org.springframework.web: DEBUG
org.springframework.validation: DEBUG
com.yourcompany: DEBUG
Would you like me to help you debug this further or explain any part of the validation setup in more detail?
Ответ дан, но слишком избыточен. Модель начала добавлять ненужный код, в том числе:
// src/main/java/com/yourcompany/config/WebConfig.java
package com.yourcompany.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class WebConfig implements WebMvcConfigurer {
// Additional web configuration can be added here if needed
}Этот класс вообще не нужен – валидация работает без него. Это конфигурация для MVC приложения, а у нас REST API.
Проблема знакомая – при сложных запросах LLM начинает генерировать лишний код.
Можно было очистить контекст и пересоздать промпт, но я решил продолжить с текущим вариантом. Валидация готова, переходим к тестам.

Тесты проходят успешно, но есть нюансы.
Дублирование verify & when
В тесте createOperation_Success дублируются verify и when.
Почему это плохо?
when(...)уже проверяет вызов метода.verify(...)имеет смысл только если проверяются все вызовы вcreateOperation.
Как лучше?
Либо использовать
verifyтолько наvoidметодах.Либо проверять все вызовы, а не только часть.
Проблема с any(Operation.class)
Тест не проверяет содержимое объекта, только его тип.
when(operationRepository.save(any(Operation.class))).thenReturn(operation);Это значит, что если внутри createOperation объект Operation изменится, тест этого не заметит.
Пример ошибки:
В коде забыли проставить категорию перед сохранением.
Тест всё равно проходит.
@Transactional
public OperationResponse createOperation(OperationCreateRequest request) {
final var category = categoryRepository.findById(request.getCategoryId())
.orElseThrow(() -> new CategoryNotFoundException(
String.format("Category with id %d not found", request.getCategoryId())));
final var operation = operationMapper.toEntity(request);
// operation.setCategory(category); // ОШИБКА!
final var savedOperation = operationRepository.save(operation);
return operationMapper.toDto(savedOperation);
}
Тест не обнаружит эту ошибку! Как исправить? Использовать ArgumentCaptor, чтобы перехватить объект, переданный в save().
Исправленный вариант теста с ArgumentCaptor
@Captor
ArgumentCaptor operationArgumentCaptor;
@Test
void createOperation_Success() {
// Arrange
when(categoryRepository.findById(1L)).thenReturn(Optional.of(category));
when(operationMapper.toEntity(createRequest)).thenReturn(operation);
when(operationRepository.save(any(Operation.class))).thenReturn(operation);
when(operationMapper.toDto(operation)).thenReturn(operationResponse);
// Act
OperationResponse result = operationService.createOperation(createRequest);
// Assert
assertThat(result).isNotNull();
assertThat(result.getPublicId()).isEqualTo("test-public-id");
// Перехватываем переданный в save объект
//captor можно вставить в verify блоке или в when блоке и там и там он отработает корректно
verify(operationRepository).save(operationArgumentCaptor.capture());
assertEquals(1, operationArgumentCaptor.getAllValues().size());
// Проверяем, что категория была установлена
var savedOperation = operationArgumentCaptor.getValue();
assertEquals(category, savedOperation.getCategory());
}
Теперь тест проверяет корректность объекта, а не просто его тип.
Избыточные данные в setUp методе
Рассмотрим всё тот же тест createOperation_Success(). Как createOperation() работает в коде:
Ищет категорию в БД
Маппит
OperationCreateRequestвOperationУстанавливает категорию в объект
OperationСохраняет объект
Operaion
В тесте объект Operation создаётся один раз в setUp() – но уже с установленной категорией. Затем этот объект возвращается в моке
when(operationMapper.toEntity(createRequest)).thenReturn(operation);Данная реализация снижает качество теста: часть логики createOperation() не проверяется. В будущем это может привести к багам, которые останутся незамеченными.
Кодстайл и "вкусовщина"
Тестируемый класс назван
operationServiceвместоsut(System Under Test), по второму варианту сразу видно, какой сервис тестируетсяГенерация тестовых данных вынесена в
@BeforeEach, но не все данные нужны в каждом тесте. Лучше вынести в приватный метод и вызывать в нужных местах.
private OperationCreateRequest buildCreateRequest() {
return new OperationCreateRequest("Тест", 100.0, "WITHDRAW", 1L);
}Так тесты будут чище и понятнее.

Что пошло не так?
Все тесты проходят, кроме трёх:
findByPublicId_NotFounddeleteOperation_NotFoundupdateOperation_NotFound
И здесь очень интересны момент, Клод ожидает, что сервис вернёт 500-ю ошибку, но на самом деле он должен отвечать 404-й (и название теста на это намекает). Тест изначально не проходил, потому что Клод никогда не добавлял обработку 500-х ошибок в ExceptionHandler. Если бы тест ожидал 404-ю ошибку, то он всё равно бы падал, т.к. при обработке валидации, была добавлена обработка лишь CategoryNotFoundException, но есть и плюс: тесты падают, а значит, их нельзя игнорировать. Это даёт шанс исправить ошибку вовремя.
Исправляем: добавляем общее исключение NotFoundException и обработку RuntimeException:
@ExceptionHandler(NotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public ValidationErrorResponse handleCategoryNotFoundException(NotFoundException ex) {
ValidationErrorResponse response = new ValidationErrorResponse();
response.getErrors().add(new ValidationErrorResponse.ValidationError(
"id",
ex.getMessage()
));
return response;
}
@ExceptionHandler(Exception.class)
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public ErrorDto handleException(Exception ex) {
return new ErrorDto(ex.getMessage());
}
private record ErrorDto(String message){}Теперь сервис корректно возвращает 404 в случае отсутствия объекта.
Разбираем тесты
Клод в целом справился, но есть несколько проблем. Тест createOperation_Success проверяет результат через jsonPath:
.andExpect(jsonPath("$.publicId").value("test-public-id"))
.andExpect(jsonPath("$.name").value("Test Operation"))
.andExpect(jsonPath("$.amount").value(100))
Проверки через jsonPath неудобны, их тяжелее читать, особенно если в модели присутствует вложенность или массив данных. Вариант с хранением json-файла с ожидаемым результатом будет намного проще.
Тест findAll_WithCustomPagination совсем не проверяет возвращаемый результат, он подготовлен, но не добавлен в проверку. findByPublicId_Success проверяет лишь id, хотя в beforeEach подготовлен целый объект.
На первый взгляд может показаться, что Клод справился хорошо но если приглядеться– не хватает проверок, а кое-где они просто отсутствуют.
PR с MVC тестами
https://github.com/nzinovev/anthropic-claude/pull/11
Итоги
Мы прошли по минимальному циклу разработки, используя ИИ:
Создали БД, таблицы и сущности.
Реализовали взаимодействие с БД через Spring JPA.
Написали CRUD-операции и обработку ошибок.
Добавили юнит-тесты и MVC-тесты.
Впечатления
Справился ли Клод с поставленной задачей?
Да, он выдал рабочий код, который можно было довести до финального состояния.
Написал ли он код уровня сеньора?
Нет. Код требовал исправлений и доработок. Клод допускал ошибки, которые опытный разработчик избежал бы сразу.
Может ли человек без опыта программирования получить такую же выдачу?
Нет, Клод справился только потому, что получал чёткие требования и правильную настройку. ИИ может писать код, но только если задающий понимает, что именно он хочет получить.
ИИ в разработке: помощник или замена?
Можно ли использовать ИИ в реальной работе?
Не просто можно, а нужно. ИИ существенно ускоряет разработку, но важно понимать его ограничения.
Ключевые принципы работы с ИИ
Чем лучше подготовлен промпт, тем лучше выдача
Если промпт размытый – код будет неполным или некорректным.
Если задать чёткий запрос – модель выдаст качественный код.
Чем меньше задача, тем выше качество
ИИ отлично справляется с небольшими блоками кода.
Если же попросить его реализовать большой модуль, он может упустить детали или перегрузить выдачу.
ИИ эффективен как помощник в написании небольших фрагментов кода, но для сложных задач нужен контроль со стороны разработчика.
Риски использования ИИ в разработке
ИИ не гарантирует идеальный код и может нести потенциальные риски.
Не стоит слепо доверять выдаче.
ИИ не анализирует код так, как разработчик. Он может допустить ошибки, которые незаметны сразу, но в будущем приведут к багам.
Конфиденциальность данных.
При работе с большими моделям такими как ChatGPT и Claude нужно быть осторожными с чувствительными и корпоративными данными. Передача кода в публичные LLM-модели несёт риск утечки данных.
Как защитить данные?
Не отправляйте коммерчески важный код в LLM. Если же вы это делаете, обязательно анонимизируйте данные перед отправкой.
Если конфиденциальность критична и анонимизация затруднена, рассмотрите вариант использования локальных LLM. Большой плюс таких моделей, что они локальны, следовательно, ваши данные не покинут просторы вашего ПК.
Нестабильное качество выдачи.
Код от ИИ бывает отличным, средним или откровенно плохим. Качество зависит не от модели, а от того, кто задаёт вопросы. ИИ – мощный инструмент, но бездумное использование может привести к проблемам.
Заменит ли ИИ разработчиков?
Когда-то – возможно. Но точно не сейчас.
ИИ пишет код, но не понимает его так, как человек.
Самая сложная часть разработки – архитектура, бизнес-логика, работа с требованиями – остаются за человеком.
ИИ – не замена, а мощный инструмент. Разработчик, который использует ИИ, будет писать код быстрее, эффективнее и качественнее. Разработчик, который не использует ИИ, будет работать дольше и медленнее.
ИИ – это не враг, а помощник, который ускоряет работу и снимает рутину.
Что дальше?
Мы рассмотрели три из четырёх поставленных вопросов. Осталось ответить на последний, какая модель лучше для программирования? Anthropic Claude? ChatGPT? DeepSeek?
Об этом – в следующей части.
Оставайтесь на связи.

Web-site. https://trustgeekshackexpert.com/ Tele-Gram, trustgeekshackexpert During the pandemic, I ventured into the world of cryptocurrency trading. My father loaned me $10,000, which I used to purchase my first bitcoins. With diligent research and some luck, I managed to grow my investment to over $350,000 in just a couple of years. I was thrilled with my success, but my excitement was short-lived when I decided to switch brokers and inadvertently fell victim to a phishing attack. While creating a new account, I received what seemed like a legitimate email requesting verification. Without second-guessing, I provided my information, only to realize later that I had lost access to my email and cryptocurrency wallets. Panic set in as I watched my hard-earned assets disappear before my eyes. Desperate to recover my funds, I scoured the internet for solutions.

In the vast and often treacherous realm of online investments, I was entangled in a web of deceit that cost me nearly $45,000. It all started innocuously enough with an enticing Instagram profile promising lucrative returns through cryptocurrency investment. Initially, everything seemed promising—communications were smooth, and assurances were plentiful. However, as time passed, my optimism turned to suspicion. Withdrawal requests were met with delays and excuses. The once-responsive "investor" vanished into thin air, leaving me stranded with dwindling hopes and a sinking feeling in my gut. It became painfully clear that I had been duped by a sophisticated scheme designed to exploit trust and naivety. Desperate to recover my funds, I turned to online forums where I discovered numerous testimonials advocating for Muyern Trust Hacker. With nothing to lose, I contacted them, recounting my ordeal with a mixture of skepticism and hope. Their swift response and professional demeanor immediately reassured me that I had found a lifeline amidst the chaos. Muyern Trust Hacker wasted no time in taking action. They meticulously gathered evidence, navigated legal complexities, and deployed their expertise to expedite recovery. In what felt like a whirlwind of activity, although the passage of time was a blur amidst my anxiety, they achieved the seemingly impossible—my stolen funds were returned. The relief I felt was overwhelming. Muyern Trust Hacker not only restored my financial losses but also restored my faith in justice. Their commitment to integrity and their relentless pursuit of resolution were nothing short of remarkable. They proved themselves as recovery specialists and guardians against digital fraud, offering hope to victims like me who had been ensnared by deception. My gratitude knows no bounds for Muyern Trust Hacker. Reach them at muyerntrusted @ m a i l - m e . c o m AND Tele gram @ muyerntrusthackertech

All you need is to hire an expert to help you accomplish that. If there’s any need to spy on your partner’s phone. From my experience I lacked evidence to confront my husband on my suspicion on his infidelity, until I came across ETHICALAHCKERS which many commend him of assisting them in their spying mission. So I contacted him and he provided me with access into his phone to view all text messages, call logs, WhatsApp messages and even her location. This evidence helped me move him off my life .

At first, I was admittedly skeptical about Worldcoin (ref: https://worldcoin.org/blog/worldcoin/this-is-worldcoin-video-explainer-series), particularly around the use of biometric data and the WLD token as a reward mechanism for it. However, after following the project closer, I’ve come to appreciate the broader vision and see the value in the underlying tech behind it. The concept of Proof of Personhood (ref: https://worldcoin.org/blog/worldcoin/proof-of-personhood-what-it-is-why-its-needed) has definitely caught my attention, and does seem like a crucial step towards tackling growing issues like bots, deepfakes, and identity fraud. Sam Altman’s vision is nothing short of ambitious, but I do think he & Alex Blania have the chops to realize it as mainstay in the global economy.

Can those who have fallen victim to fraud get their money back? Yes, you might be able to get back what was taken from you if you fell prey to a fraud from an unregulated investing platform or any other scam, but only if you report it to the relevant authorities. With the right plan and supporting documentation, you can get back what you've lost. Most likely, the individuals in control of these unregulated platforms would attempt to convince you that what happened to your money was a sad accident when, in fact, it was a highly skilled heist. You should be aware that there are resources out there to help you if you or someone you know has experienced one of these circumstances. Do a search using (deftrecoup (.) c o m). Do not let the perpetrators of this hoaxes get away with ruining you mentally and financially.

Being a parent is great until your toddler figures out how to use your devices. One afternoon, I left my phone unattended for just a few minutes rookie mistake of the century. I thought I’d take a quick break, but little did I know that my curious little genius was about to embark on a digital adventure. By the time I came back, I was greeted by two shocking revelations: my toddler had somehow managed to buy a $5 dinosaur toy online and, even more alarmingly, had locked me out of my cryptocurrency wallet holding a hefty $75,000. Yes, you heard that right a dinosaur toy was the least of my worries! At first, I laughed it off. I mean, what toddler doesn’t have a penchant for expensive toys? But then reality set in. I stared at my phone in disbelief, desperately trying to guess whatever random string of gibberish my toddler had typed as a new password. Was it “dinosaur”? Or perhaps “sippy cup”? I felt like I was in a bizarre game of Password Gone Wrong. Every attempt led to failure, and soon the laughter faded, replaced by sheer panic. I was in way over my head, and my heart raced as the countdown of time ticked away. That’s when I decided to take action and turned to Digital Tech Guard Recovery, hoping they could solve the mystery that was my toddler’s handiwork. I explained my predicament, half-expecting them to chuckle at my misfortune, but they were incredibly professional and empathetic. Their confidence put me at ease, and I knew I was in good hands.

In a world brimming with enticing investment opportunities, it is crucial to tread carefully. The rise of digital currencies has attracted many eager investors, but along with this excitement lurk deceitful characters ready to exploit the unsuspecting. I learned this lesson the hard way, and I want to share my story in the hopes that it can save someone from making the same mistakes I did. It all began innocently enough when I came across an engaging individual on Facebook. Lured in by promises of high returns in the cryptocurrency market, I felt the electric thrill of potential wealth coursing through me. Initial investments returned some profits, and that exhilarating taste of success fueled my ambition. Encouraged by a meager withdrawal, I decided to commit even more funds. This was the moment I let my guard down, blinded by greed. As time went on, the red flags started to multiply. The moment I tried to withdraw my earnings, a cascade of unreasonable fees appeared like a thick mist, obscuring the truth. “Just a little more,” they said, “Just until the next phase.” I watched my hard-earned money slip through my fingers as I scraped together every last cent to pay those relentless fees. My trust had become my downfall. In the end, I lost not just a significant amount of cash, but my peace of mind about $1.1 million vanished into the abyss of false promises and hollow guarantees. But despair birthed hope. After a cascade of letdowns, I enlisted the help of KAY-NINE CYBER SERVICES, a team that specializes in reclaiming lost funds from scams. Amazingly, they worked tirelessly to piece together what had been ripped away, providing me with honest guidance when I felt utterly defeated. Their expertise in navigating the treacherous waters of crypto recovery was a lifeline I desperately needed. To anyone reading this, please let my story serve as a warning. High returns often come wrapped in the guise of deception. Protect your investments, scrutinize every opportunity, and trust your instincts. Remember, the allure of quick riches can lead you straight to heartbreak, but with cautious determination and support, it is possible to begin healing from such devastating loss. Stay informed, stay vigilant, and may you choose your investment paths wisely. Email: kaynine @ cyberservices . com

The biggest issue with cryptocurrency is that it is unregulated, wh ich is why different people can come up with different fake stories all the time, and it is unfortunate that platforms like Facebook and others only care about the money they make from them through ads. I saw an ad on Facebook for Cointiger and fell into the scam, losing over $30,000. I reported it to Facebook, but they did nothing until I discovered deftrecoup . c o m from a crypto community; they retrieved approximately 95% of the total amount I lost.

REACH OUT TO THEM WhatsApp + 156 172 63 697 Telegram (@)Techcyberforc We were in quite a bit of distress. The thrill of our crypto investments, which had once sparked excitement in our lives, was slowly turning into anxiety when my husband pointed out unusual withdrawal issues. At first, we brushed it off as minor glitches, but the situation escalated when we found ourselves facing login re-validation requests that essentially locked us out of our crypto wallet—despite entering the correct credentials. Frustrated and anxious, we sought advice from a few friends, only to hit a wall of uncertainty. Turning to the vast expanse of the internet felt daunting, but in doing so, we stumbled upon TECH CYBER FORCE RECOVERY.

Online crypto investment can seem like a promising opportunity, but it's crucial to recognize that there are no guarantees. My experience serves as a stark reminder of this reality. I was drawn in by the allure of high returns and the persuasive marketing tactics employed by various brokers. Their polished presentations and testimonials made it seem easy to profit from cryptocurrency trading. Everything appeared to be legitimate. I received enticing messages about the potential for substantial gains, and the brokers seemed knowledgeable and professional. Driven by excitement and the fear of missing out, I invested a significant amount of my savings. The promise of quick profits overshadowed the red flags I should have noticed. I trusted these brokers without conducting proper research, which was a major mistake. As time went on, I realized that the promised returns were nothing but illusions. My attempts to withdraw funds were met with endless excuses and delays. It became painfully clear that I had fallen victim. The reality hit hard: my hard-earned money was gone, I lost my peace of mind and sanity. In my desperation, I sought help from a company called DEFTRECOUP. That was the turning point for me as I had a good conversation and eventually filed a complaint via DEFTRECOUP COM. They were quite delicate and ensured I got out of the most difficult situation of my life in one piece.

When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER.

After falling victim to a fraudulent Bitcoin mining scam, I found myself in a desperate situation. I had invested $50,000 into a cloud mining website called Miningpool, which turned out to be a complete scam. For months, I tried reaching out to the company, but I was unable to access my funds, and I quickly realized I had been taken for a ride. In my search for help, I came across TrustGeeks Hack Expert, a service that claimed to help people recover lost funds from crypto scams. Though skeptical at first, I decided to give them a try. Here’s my experience with their service.When I initially contacted TrustGeeks Hack Expert Email.. Trustgeekshackexpert{At}fastservice{Dot}com , I was understandably hesitant. Like many others, I had been tricked into believing my Bitcoin investments were legitimate, only to discover they were locked in a non-spendable wallet with no way of accessing them. However, after sharing my story and details about the scam, the team assured me they had handled similar cases and had the expertise to help. They requested basic information about my investment and began their investigation immediately. The recovery process was nothing short of professional. Unlike many other services that promise quick fixes but fail to deliver, TrustGeeks Hack Expert kept me informed at every stage. They regularly updated me on their progress and were completely transparent about the challenges they faced. There were moments when I wondered if the process would work, but the team’s professionalism and reassurance gave me hope. They were honest about the time it would take and did not make any unrealistic promises, which I truly appreciated. After several weeks of work, TrustGeeks Hack Expert successfully recovered not just my $50,000 investment, but also the so-called profits that had been locked away in the scam's non-spendable wallet. This was a huge relief, as I had resigned myself to the idea that I had lost everything. The entire recovery process was discreet and handled with the utmost care, ensuring that the scam company remained unaware of the recovery efforts, which helped prevent further complications.

For months, I tried reaching out to the company, but I was unable to access my funds, and I quickly realized I had been taken for a ride. In my search for help, I came across TrustGeeks Hack Expert, a service that claimed to help people recover lost funds from crypto scams. Though skeptical at first, I decided to give them a try. Here’s my experience with their service.When I initially contacted TrustGeeks Hack Expert Email.. Trustgeekshackexpert{At}fastservice{Dot}com , I was understandably hesitant. Like many others, I had been tricked into believing my Bitcoin investments were legitimate, only to discover they were locked in a non-spendable wallet with no way of accessing them. However, after sharing my story and details about the scam, the team assured me they had handled similar cases and had the expertise to help. They requested basic information about my investment and began their investigation immediately. The recovery process was nothing short of professional. Unlike many other services that promise quick fixes but fail to deliver, TrustGeeks Hack Expert kept me informed at every stage. They regularly updated me on their progress and were completely transparent about the challenges they faced. There were moments when I wondered if the process would work, but the team’s professionalism and reassurance gave me hope. They were honest about the time it would take and did not make any unrealistic promises, which I truly appreciated. After several weeks of work, TrustGeeks Hack Expert successfully recovered not just my $50,000 investment, but also the so-called profits that had been locked away in the scam's non-spendable wallet. This was a huge relief, as I had resigned myself to the idea that I had lost everything. The entire recovery process was discreet and handled with the utmost care, ensuring that the scam company remained unaware of the recovery efforts, which helped prevent further complications.

DUNAM CYBER SOLUTION BTC-ETH RECOVERY EXPERT I had tried to secure my Bitcoin wallet, maybe a bit too aggressively, enabling every security feature imaginable: two-factor authentication, biometric verification, intricate passwords-the whole shebang. I wanted to make it impossible for anybody to get to my money. I tried to make this impregnable fortress of security and ended up locking myself out of my wallet with $700,000 in Bitcoin. It wasn't until I tried to access my wallet that I realized the trap I had set for myself. I was greeted with an endless series of security checks-passwords, codes, facial recognition, and more. I could remember parts of my multi-layered security setup but not enough to actually get in. In fact, my money was behind this digital fortress, and the more I tried to fix it, the worse it seemed to get. I kept tripping over my own layers of protection, unable to find a way back in. Panic quickly set in when I realized I had made it almost impossible for myself to access my own money. That is when I called DUNAMIS CYBER SOLUTION From that very first call, they reassured me that I wasn't the first person to make this kind of mistake and certainly wouldn't be the last. They listened attentively to my explanation and got to work straight away. Their team methodically began to untangle my overly complicated setup. Patience and expertise managed to crack each layer of security step by step until they had restored access to my wallet. [email protected] +13433030545 [email protected]

Losing access to my crypto wallet account was one of the most stressful experiences ever. After spending countless hours building up my portfolio, I suddenly found myself locked out of my account without access. To make matters worse, the email address I had linked to my wallet was no longer active. When I tried reaching out, I received an error message stating that the domain was no longer in use, leaving me in complete confusion and panic. It was as though everything I had worked so hard for was gone, and I had no idea how to get it back. The hardest part wasn’t just the loss of access it was the feeling of helplessness. Crypto transactions are often irreversible, and since my wallet held significant investments, the thought that my hard-earned money could be lost forever was incredibly disheartening. I spent hours scouring forums and searching for ways to recover my funds, but most of the advice seemed either too vague or too complicated to be of any real help.

My name is Marta, and I’m sharing my experience in the hope that it might help others avoid a similar scam. A few weeks ago, I received an email that appeared to be from the "Department of Health and Human Services (DHS)." It claimed I was eligible for a $72,000 grant debit card, which seemed like an incredible opportunity. At first, I was skeptical, but the email looked so professional and convincing that I thought it might be real. The email instructed me to click on a link to claim the grant, and unfortunately, I followed through. I filled out some personal details, and then, unexpectedly, I was told I needed to pay a "processing fee" to finalize the grant. I was hesitant, but the urgency of the message pushed me to make the payment, believing it was a necessary step to receive the funds. Once the payment was made, things quickly went downhill. The website became unreachable, and I couldn’t get in touch with anyone from the supposed DHS. It soon became clear that I had been scammed. The email, which seemed so legitimate, had been a clever trick to steal my money.Devastated and unsure of what to do, I began searching for ways to recover my lost funds. That’s when I found Tech Cyber Force Recovery, a team of experts who specialize in tracing stolen money and assisting victims of online fraud. They were incredibly reassuring and quickly got to work on my case. After several days of investigation, they managed to track down the scammers and recover my funds. I can’t express how grateful I am for their help. Without Tech Cyber Force Recovery, I don’t know what I would have done. This experience has taught me a valuable lesson: online scams are more common than I realized, and the scammers behind them are incredibly skilled. They prey on people’s trust, making it easy to fall for their tricks. HOW CAN I RECOVER MY LOST BTC,USDT =Telegram= +1 561-726-36-97 =WhatsApp= +1 561-726-36-97

I'm incredibly grateful that I did enough research to recover my stolen cryptocurrency. When I first fell victim to a scam, I felt hopeless and lost, unsure if I'd ever see my funds again. A few months ago, I was approached by someone on Telegram who claimed to have a lucrative investment opportunity in cryptocurrencies. They promised huge returns and played on my emotions, making it seem like a can't-miss chance. I was so eager to make my money grow that I didn't fully vet the situation, and unfortunately, I ended up falling for the scam. They guided me to invest a significant amount of money, and soon after, I realized I had been duped. The scammers blocked me, and my funds were gone. I felt devastated. All of my savings had been wiped out in what seemed like an instant, and the feeling of being taken advantage of was crushing. I spent days researching how to recover my stolen cryptocurrency but found the process to be overwhelming and complicated. I was starting to lose hope when I came across Trust Geeks Hack Expert.

I invested substantially in Bitcoin, believing it would secure my future. For a while, things seemed to be going well. The market fluctuated, but I was confident my investment would pay off. But catastrophe struck without warning. I lost access to my Bitcoin holdings as a result of several technical issues and inadequate security measures. Every coin in my wallet suddenly disappeared, leaving me with an overpowering sense of grief. The emotional impact of this loss was far greater than I had imagined. I spiraled into despair, feeling as though my dreams of financial independence were crushed. I was on the verge of giving up when I came across Assets_Recovery_Crusader. Being willing to give them a chance, I had nothing left to lose. They listened to my narrative and took the time to comprehend the particulars of my circumstance, rather than treating me like a case number. They worked diligently, using their advanced recovery techniques and deep understanding of blockchain technology to track down my lost Bitcoin. Assets_Recovery_Crusader rebuilt my trust in the bitcoin space. The financial impact had a significant emotional toll, but I was able to get past it thanks to Assets_Recovery_Crusader’s proficiency and persistence.

HIRE A HACKE DUNAMIS CYBER SOLUTIONI was just hours away from sealing the biggest real estate deal of my life- the kind of deal that would make one feel like a financial genius. It was the dream property, and all I had to do was transfer my $450,000 Bitcoin deposit. Simple, right? Wrong. I pulled up my crypto wallet, ready to finalize the transfer, and access was denied. No big deal. Maybe I mistyped the password. I tried again. Access denied. Panic started seeping in. I switched devices. Rebooted my system. I entered every password I had ever used since the dawn of time, including my childhood nickname and my favorite pizza topping. Still. Nothing. This wasn't a glitch. This was a full-scale disaster. The seller was waiting; my real estate agent was waiting. And my money? Trapped in a digital vault I suddenly had no key to. Every worst-case scenario flooded my head: Had I been hacked? Did I lock myself out? Was this some kind of cosmic payback for every time I blew off software updates? Just about the time I was getting comfortable in my new identity as the guy who almost bought a house, I remembered that a friend, a crypto lawyer-once said something to me about a recovery service. I called him with the urgency of a man dangling off a cliff. The moment I said what happened, he cut me off: "Email DUNAMIS CYBER SOLUTION Recovery. Now." I didn't ask questions. I dialed quicker than I'd ever dialed in my life. From the second they answered, I knew I was with the pros. There was no hemming, no hawing; this team must have handled its fair share of this particular type of nightmare. They talked me through the process, asked the right questions, and went to work like surgeons in a digital operating room. Minutes felt like hours. I was at DEFCON 1, stress-wise. I paced and stared at my phone, wondering if it was time to move into a cave because, at this rate, homeownership was not looking good. Then—the call came: "We got it." I just about collapsed with relief. My funds were safe. My wallet was unlocked. The Bitcoin was transferred just in time, and I signed the contract with literal seconds to spare. And that night, almost lost to the tech catastrophe of the century in that house, I made a couple of vows: never underestimate proper wallet management and always keep DUNAMIS CYBER SOLUTION Recovery on speed dial.

TELEGRAM: u/BestwebwizardRecovery EMAIL: [email protected] WEBSITE: https://bestwebwizrecovery.com/ The money I invested was meant for something incredibly important—my wedding. After months of saving, I had finally accumulated enough to make the day truly special. Wanting to grow this fund, I came across a crypto site called Abcfxb.pro, which promised daily returns through “AI crypto arbitrage trading.” They claimed they could deliver 1% returns on my investment every day, and I saw this as an opportunity to multiply my savings quickly. I thought it was the perfect way to ensure I’d have enough to cover all the wedding expenses. For the first few days, everything seemed perfect. I saw the promised returns and was able to withdraw money without any issues. It felt like a legitimate opportunity, and I was excited as my wedding fund grew. However, things took a turn when I tried to withdraw again. The site claimed that my account balance had fallen below their liquidity requirement and asked me to deposit more funds to proceed. Reluctantly, I deposited more money, believing it was just a minor issue. But the situation only worsened. I was then told that my withdrawal would take 50 days due to “blockchain congestion.” I wasn’t too concerned at first, thinking it was just a delay. But after 50 days, I still hadn’t received my funds, and they gave me the same excuse. Desperate, I contacted the site again, only to be informed that I would need to pay a 15% fee for “technical support” from the “Federal Reserve’s blockchain regulator” before I could withdraw my money. By now, I realized I had fallen victim to a scam. As I researched further, I found that others had been scammed in the same way, and the scammers had moved to another site with nearly the same layout. It was then that I came across a review from another victim, who explained how Best Web Wizard Recovery had helped him recover his lost funds. Desperate for a solution, I reached out to Best Web Wizard Recovery. To my relief, they responded quickly and professionally. Within six hours, they had successfully recovered my full investment. I was beyond grateful, especially since the money had been intended for my wedding. Thanks to their help, I was able to not only get my money back but also go ahead with my wedding as planned. It was a day I will always cherish, and I owe it to Best Web Wizard Recovery for helping me make it a reality. I highly recommend their services to anyone who has fallen victim to a crypto scam.

I lost $210,000 worth of Bitcoin to a group of fake blockchain impostors on Red note, a Chinese app. They contacted me, pretending to be official blockchain support, and I was misled into believing they were legitimate. At the time, I had been saving up in Bitcoin, hoping to take advantage of the rising market. The scammers were convincing, and I made the mistake of trusting them with access to my blockchain wallet. To my shock and disbelief, they stole a total of $10,000 worth of Bitcoin from my wallet. It was devastating, as this amount represented all of my hard-earned savings. I was in utter disbelief, feeling foolish for falling for their deceptive tactics. I felt lost, as though everything I had worked towards was taken from me in an instant. Thankfully, my uncle suggested I reach out to an expert in cryptocurrency recovery. After doing some research online, I came across CYBERPOINT RECOVERY COMPANY. I was hesitant at first, but their positive reviews gave me some hope.

I never imagined I would find myself in a situation where I was scammed out of such a significant amount of money, but it happened. I became a victim of a fake online donation project that cost me over $30,000. It all started innocently enough when I was searching for assistance after a devastating fire incident in California. While looking for support, I came across an advertisement that seemed to offer donations for fire victims. The ad appeared legitimate, and I reached out to the project manager to inquire about how to receive the donations. The manager was very convincing and insisted that in order to qualify for the donations, I needed to pay $30,000 upfront. In return, I was promised $1 million in donations. It sounded a bit too good to be true, but in my desperate situation, I made the mistake of believing it. The thought of receiving a substantial amount of help to rebuild after the fire clouded my judgment, and I went ahead and sent the money. However, after transferring the funds, the promised donations never arrived, and the manager disappeared. That’s when I realized I had been scammed. Feeling lost, helpless, and completely betrayed, I tried everything I could to contact the scammer, but all my efforts were in vain. Desperation led me to search for help online, hoping to find a way to recover my money and potentially track down the scammer. That’s when I stumbled upon several testimonies from others who had fallen victim to similar scams and had been helped by a company called Tech Cyber Force Recovery. I reached out to them immediately, providing all the details of the scam and the information I had gathered. To my immense relief, the experts at Tech Cyber Force Recovery acted swiftly. Within just 27 hours, they were able to locate the scammer and initiate the recovery process. Not only did they help me recover the $30,000 I had lost, but the most satisfying part was that the scammer was apprehended by local authorities in their region. Thanks to Tech Cyber Force Recovery, I was able to get my money back and hold the scammer accountable for their actions. I am incredibly grateful for their professionalism, expertise, and dedication to helping victims like me.

Living in Los Angeles, I never imagined I’d face such a difficult chapter in my life. At the time, my wife was pregnant, and we were both excited about starting a family. I fell victim to a series of scams, losing over $170,000 in total. Just when I thought things couldn’t get worse, I received a call from someone who promised to help me recover my losses. Desperate to fix the situation, I went along with it, hoping for a breakthrough. But it turned out to be another scam.

Mark Zuckerberg. That’s the name I was introduced to when I first encountered the cryptocurrency mining platform, WHATS Invest. A person claiming to be Zuckerberg himself reached out to me, saying that he was personally backing the platform to help investors like me earn passive income. At first, I was skeptical—after all, how often do you get a direct connection to one of the world’s most famous tech entrepreneurs? But this individual seemed convincing and assured me that many people were already seeing substantial returns on their investments. He promised me a great opportunity to secure my financial future, so I decided to take the plunge and invest $10,000 into WHATS Invest. They told me that I could expect to see significant returns in just a few months, with payouts of at least $1,500 or more each month. I was excited, believing this would be my way out of financial struggles. However, as time passed, things didn’t go according to plan. Months went by, and I received very little communication. When I finally did receive a payout, it was nowhere near the $1,500 I was promised. Instead, I received just $200, barely 13% of what I had expected. Frustrated, I contacted the support team, but the responses were vague and unhelpful. No clear answers or solutions were offered, and my trust in the platform quickly started to erode. It became painfully clear that I wasn’t going to get anywhere with WHATS Invest, and I began to worry that my $10,000 might be lost for good. That's when I discovered Certified Recovery Services. Desperate to recover my funds, I decided to reach out to them for help. In just 24 hours, they worked tirelessly to recover the majority of my funds, successfully retrieving $8,500 85% of my initial investment. I couldn’t believe how quickly and efficiently they worked to get my money back. I’m extremely grateful for Certified Recovery Servicer's fast and professional service. Without them, I would have been left with a significant loss, and I would have had no idea how to move forward. If you find yourself in a similar situation with WHATS Invest or any other platform that isn’t delivering as promised, I highly recommend reaching out to Certified Recovery Services They were a lifesaver for me, helping me recover nearly all of my funds. It's reassuring to know that trustworthy services like this exist to help people when things go wrong. They also specialize in recovering money lost to online scams, so if you’ve fallen victim to such a scam, don’t hesitate to contact Certified Recovery Services they can help!

Weddings are supposed to be magical, but the months leading up to mine were anything but. Already, wedding planning was a high-stress, sleep-deprived whirlwind: endless details to manage, from venue deposits and guest lists to dress fittings and vendor contracts. But nothing-and I mean, nothing-compared to the panic that washed over me when I realized that somehow, I had lost access to my Bitcoin wallet-with $600,000 inside. It happened in the worst possible way. In between juggling my to-do lists and trying to keep my sanity intact, I lost my seed phrase. I went through my apartment like a tornado, flipping through notebooks, checking every email, every file-nothing. I sat there in stunned silence, heart pounding, trying to process the fact that my entire savings, my security, and my financial future might have just vanished. In utter despair, I vented to my bridesmaid's group chat for some sympathetic words from the girls. Instead, one casually threw out a name that would change everything in a second: "Have you ever heard of Tech Cyber Force Recovery? They recovered Bitcoin for my cousin. You should call them." I had never heard of them before, but at that moment, I would have tried anything. I immediately looked them up, scoured reviews, and found story after story of people just like me—people who thought they had lost everything, only for Tech Cyber Force Recovery to pull off the impossible. That was all the convincing I needed. From the very first call, I knew I was in good hands. Their team was calm, professional, and incredibly knowledgeable. They explained the recovery process in a way that made sense, even through my stress-fogged brain. Every step of the way, they kept me informed, reassured me, and made me feel like this nightmare actually had a solution. And then, just a few days later, I got the message: "We have recovered your Bitcoin." (EMAIL. support @ tech cyber force recovery . com) OR WHATSAPP (+1 56 17 26 36 97) I could hardly believe my eyes: Six. Hundred. Thousand. Dollars. In my hands again. I let out my longest breath ever and almost cried, relieved. It felt like I woke up from a bad dream, but it was real, and Tech Cyber Force Recovery had done it. Because of them, I walked down the aisle not just as a bride, but as someone who had dodged financial catastrophe. Instead of spending my honeymoon stressing over lost funds, I got to actually enjoy it—knowing that my wallet, and my future, were secure. Would I refer to them? In a heartbeat. If you ever find yourself in that situation, please don't freak out, just call Tech Cyber Force Recovery. They really are the real deal.
