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
Подготавливаю новый промпт с историей взаимодействия:
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.

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.

God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns. You reach them Call/Text Number +1 (336)390-6684 His Email: [email protected] Contact Telegram: @Capitalcryptorecover Via Contact: [email protected] His website: https://recovercapital.wixsite.com/capital-crypto-rec-1

A few months ago, I fell for what I thought was a legitimate staking platform. It looked so professional, had fake reviews, and everything seemed real. I transferred a significant amount of ETH into it, only to find out later that it was a complete scam. The site vanished, support stopped replying, and the wallet address I sent my funds to started moving the crypto across multiple chains. I felt completely helpless. I spent days blaming myself and trying to accept the loss, but part of me wasn’t ready to give up. That’s when someone recommended Asset-Resolute. I didn’t expect much, but I reached out and explained everything. To my surprise, they actually listened and started investigating right away. They traced my stolen funds through several wallets and gave me a full report of where it had moved. I honestly didn’t understand most of the technical details, but they broke it down clearly and kept me updated throughout the process. After some coordination and effort, they managed to recover a portion of my crypto. I never thought I’d see anything again, so getting anything back felt like a miracle. I just wanted to share this in case someone else out there is feeling the same panic and regret I felt. It’s not always the end. Reach out to Asset-Resolute at [email protected]. They gave me hope when I had none left.

As the finance director of a humanitarian NGO, I have always exercised extreme diligence in how we handle our funding. So when I received an email from what appeared to be a prestigious global crypto foundation offering $500000 in matching grants for blockchain-based aid initiatives, I took notice. The proposal seemed credible, complete with polished branding, legal agreements, and referenced success stories. The only stipulation was an activation requirement: we had to transfer $250000 in USDT to initiate the grant process. After extensive internal consultation and document verification, we proceeded. The promise of doubling our operational funding could significantly amplify our outreach programs in conflict-affected regions. Then everything went silent. Follow-up emails were ignored, the contact number was disconnected, and within days, the foundation’s website vanished. The realization hit us hard; we had been defrauded. The emotional and reputational toll was immense. I felt personally culpable for having signed off on such a monumental error. It jeopardized not only our funding but also trust among our stakeholders. We turned to TECHY FORCE CYBER RETRIEVAL. Their response was immediate and professional. Within hours, we were assigned a dedicated case analyst. Their team operated with surgical precision. We learned we weren’t the only victims. This was a coordinated scam ring targeting nonprofits using highly customized and persuasive tactics. TECHY FORCE CYBER RETRIEVAL’s digital forensics experts tracked the stolen USDT through a labyrinth of six wallet addresses across various jurisdictions. Using advanced blockchain analytics, real-time monitoring software, and legal liaisons, they mapped the laundering trail with remarkable accuracy. They also coordinated directly with international regulators and the legal department of the real crypto foundation, which was alarmed to discover its identity had been fraudulently used. The recovery effort was rigorous and multifaceted, involving compliance teams at multiple exchanges, forensic IP tracing, and the audit of smart contracts linked to fraudulent addresses. Throughout the ordeal, we were provided with frequent updates and full transparency. In just 10 days, TECHY FORCE CYBER RETRIEVAL successfully retrieved $191000 of the lost funds. Beyond the monetary recovery, they provided us with a comprehensive post-incident report, enabling us to strengthen our cybersecurity protocols and conduct risk training for partner organizations.

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company.

My Wild Ride: How a Wizard Hilton Cyber Tech Helped Me Recover Lost Bitcoin of 103,000 It all started when I had the misfortune of misplacing the digital wallet containing my substantial cryptocurrency holdings - a staggering 103,000 bitcoins. I had amassed this sizable fortune over the years through strategic investments and careful trading, but in a moment of carelessness, the private keys to my digital wallet had vanished. Panic set in as I grappled with the gravity of my situation - those bitcoins, worth millions at the time, were effectively lost to the ether, inaccessible and seemingly unrecoverable. Just when I had resigned myself to the devastating financial blow, a chance encounter with a self-proclaimed "digital wizard" Wizard Hilton Cyber Tech presented a glimmer of hope. This enigmatic individual, who operated in the shadowy corners of the crypto underworld, claimed to possess the arcane knowledge and skills necessary to retrieve my lost digital wealth. Intrigued and desperate, I put my skepticism aside and entrusted this mysterious wizard with the task. What followed was a wild, suspenseful journey into the depths of blockchain technology and cryptography, as the wizard navigated complex algorithms, exploited vulnerabilities, and pieced together the puzzle of my missing private keys. After days of intense effort, Wizard Hilton Cyber Tech emerged triumphant, having successfully recovered the entirety of my 103,000 bitcoin stash. The sheer relief and elation I felt in that moment was indescribable, as I regained access to my small digital fortune and was able to secure my financial future. This harrowing experience taught me the invaluable lesson of never taking the security of my cryptocurrency holdings for granted, and the importance of always maintaining the utmost diligence when it comes to protecting one's digital wealth.

My name is Martha, and I never thought I’d be the victim of a crypto scam, but life has a way of humbling you. A few months ago, I invested a huge chunk of my savings, decades of hard-earned money into what seemed like a promising crypto platform. The slick website, glowing testimonials, and a charming advisor convinced me to transfer 15 Bitcoin, into their wallet. Days later, the platform vanished, my funds were gone, and I was left with nothing but regret. Desperate, I turned to the internet, scouring forums and posts on X for help. That’s when I stumbled across Alpha Spy Nest, a shadowy group of cyber-recovery experts specializing in crypto fraud. Their reputation was murky but promising whispers of successful recoveries and a no-nonsense approach. I reached out through their encrypted portal, half-expecting a scam. Within hours, they responded, asking for details: transaction IDs, wallet addresses, and screenshots of my interactions with the scammers. Alpha Spy Nest operated in the dark corners of the web, using a mix of blockchain forensics, social engineering, and unconventional methods to track lost crypto. They traced my Bitcoin to a series of obfuscated wallets, likely controlled by an offshore syndicate. The team deployed advanced chain-analysis tools to follow the funds, pinpointing a weak link in the scammers’ network, a poorly secured exchange account in Eastern Europe.Over weeks, Alpha Spy Nest worked tirelessly, infiltrating the scammers’ digital trails. And then i received a message, we’ve got a lead. They’d recovered 12 of my 15 Bitcoin, transferred to a secure wallet they set up for me. The rest, they said, was likely gone forever, but I was overjoyed. My savings were partially restored, and I felt a weight lift. I never met them, but they gave me back hope and a lesson, the crypto world is a jungle, but sometimes, even in the dark, there are allies.

Hi everyone, I'm an entrepreneur, and when I learned about cryptocurrencies and how they potentially triple my income, I was excited to invest. I hope this message finds the correct audience. On the internet, I came across someone who assured me of exceptionally significant returns on my investment. I was readily persuaded by this man's seeming wisdom. I quickly discovered that this cryptocurrency was a hoax and that I was unable to withdraw my money after making a substantial investment. My business was in tatters, and I owed money.Fortunately for me, a pop-up regarding cryptocurrency recovery and cybersecurity specialists that could help me get all of my money back appeared when seeking for help on the internet. This organization, WIZARD JAMES RECOVERY, is a cyber security and cryptocurrency recovery firm that helped me get my investment money back. I sincerely appreciate their assistance and heartily endorse them to anyone in need of cryptocurrency recovery. The following is their contact information: E - M A I L: [email protected] W H A T S A P P: (+ 44 741 836 7204)

RECLAIM CRYPTO LOSS: HIRE META TECH RECOVERY PRO TO RECOVER LOST ASSET BACK. The adage "all that glitters is not gold" proved a harsh reality I recently encountered. The digital realm of cryptocurrency investments and exchange platforms is not immune to deception. My pursuit of cryptocurrency investments led me to a seemingly legitimate site, complete with convincing investor testimonials touting successful withdrawals. Unbeknownst to me, it was an elaborate scheme. I invested $210,000.00 worth of cryptocurrency across multiple wallets, as directed by the scammers. Initially, the process mirrored typical modern investments, but my withdrawal requests were met with evasiveness and silence. This represented my entire life savings, accumulated through years of dedicated work, now vanished in an instant. Refusing to accept defeat, I sought assistance from METATECH-RECOVERYPRO, which facilitated a successful recovery. Their process was remarkably efficient. They meticulously traced my lost funds back to the perpetrators, and within a short timeframe, the recovered assets were returned to my bank account. Without this exceptional recovery team, which offered support when all hope seemed lost, my situation would have been dire. To initiate your recovery, I strongly advise sending a detailed email ([email protected]) of your task, outlining your specific circumstances.

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time. If you’ve been a victim of a crypto scam, I highly recommend them with full confidence contacting: 📧 Email: [email protected] 📱 Telegram: @Capitalcryptorecover Contact: [email protected] 📞 Call/Text: +1 (336) 390-6684 🌐 Website: https://recovercapital.wixsite.com/capital-crypto-rec-1

HOW I RECOVER MY LOST FUNDS AFTER INVESTING Exercise extreme caution when dealing with this company. They scammed me $800,000 out of my money and even gained unauthorized access to my banking information, which severely impacted my financial well-being. I had initially approached them with the hope of improving my life through investment, but instead, I was deceived. This company should be thoroughly investigated and shut down to prevent further harm. Fortunately, I was able to recover my funds thanks to Mrs. Rose. Although I was initially hesitant and unsure about contacting her, I decided to take the risk and I’m so glad I did. You can reach her via telegram 📱(@RoseCyberHives) and email rosecryptorecovery@gmail. com With the help of her skilled team of cybersecurity professionals and cryptocurrency experts, I was able to recover my lost funds quickly and with minimal stress, a sharp contrast to my previous experience.

A recruiter named Emma Zhang reached out to me on LinkedIn regarding an intriguing job opportunity that piqued my interest. She presented a position for a Crypto Security Specialist with a Coinbase-certified firm. Her profile appeared legitimate, boasting over 1200 connections and numerous endorsements from industry professionals that seemed authentic. The offer was enticing: a salary of $180,000 plus bonuses, all disbursed in Bitcoin. The recruiter promptly sent me an email from a seemingly official domain , which closely resembled Coinbase's actual email addresses. It felt like an incredible opportunity. However, there was a stipulation: to qualify for the position, I needed to confirm that I possessed at least 4 BTC. This requirement struck me as peculiar but not entirely implausible, given the nature of the role. At that moment, I had sufficient BTC to meet the demand, so I decided to proceed. The HR representative directed me to a portal that closely mimicked Coinbase's official interface. It was convincing enough that I didn’t hesitate to log in and complete the necessary steps. Unfortunately, that was where everything began to unravel. I was instructed to send a verification deposit of 1 BTC to confirm my ownership. Since everything appeared legitimate, I complied without hesitation. However, the moment I transferred the BTC, an unsettling feeling washed over me. The following day, I noticed that the remaining 3 BTC in my wallet began to vanish. My heart sank as I realized something was terribly amiss. I immediately attempted to reach out to both the HR representative and the company, but my efforts were met with silence. Upon checking the LinkedIn profiles of Emma Zhang and her team, I discovered they had mysteriously vanished. I was left with nothing no job offer, no recruiter, and no Bitcoin. I turned to the internet in search of solutions. That’s when I stumbled upon RAPID DIGITAL RECOVERY, a company specializing in Bitcoin recovery. I contacted them, and they assured me they could assist in recovering my lost funds. After a tense and arduous process, they successfully retrieved my stolen BTC. The relief I felt was indescribable, and I am profoundly grateful to RAPID DIGITAL RECOVERY for their expertise and unwavering support.

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time. If you’ve been a victim of a crypto scam, I highly recommend them with full confidence contacting: 📧 Email: [email protected] 📱 Telegram: @Capitalcryptorecover Contact: [email protected] 📞 Call/Text: +1 (336) 390-6684 🌐 Website: https://recovercapital.wixsite.com/capital-crypto-rec-1

HOW I RECOVER MY LOST FUNDS AFTER INVESTING Exercise extreme caution when dealing with this company. They scammed me $800,000 out of my money and even gained unauthorized access to my banking information, which severely impacted my financial well-being. I had initially approached them with the hope of improving my life through investment, but instead, I was deceived. This company should be thoroughly investigated and shut down to prevent further harm. Fortunately, I was able to recover my funds thanks to Mrs. Rose. Although I was initially hesitant and unsure about contacting her, I decided to take the risk and I’m so glad I did. You can reach her via telegram (@RoseCyberHives) and email rosecryptorecovery@gmail. com With the help of her skilled team of cybersecurity professionals and cryptocurrency experts, I was able to recover my lost funds quickly and with minimal stress, a sharp contrast to my previous experience. If you’ve been scammed or are in a similar situation, I highly recommend reaching out to her for assistance. via telegram (@RoseCyberHives) rosecryptorecovery@gmail. com

After my wife passed, I found myself lonely and searching for connection. I joined a senior living forum just to talk with others my age to share stories, maybe feel a little less isolated. That’s where I met a man who claimed to be helping retirees like me manage their savings with cryptocurrency. He spoke warmly and convincingly about a retirement care fund that guaranteed lifetime monthly payouts. He said it was specifically designed for people in my stage of life safe secure and backed by health organizations. He gained my trust over weeks of conversation. We spoke daily. He called me by name asked about my late wife, and remembered little details about my life. I believed he genuinely cared. Eventually, I transferred $200000 in USDT the majority of my retirement savings, into the wallet address he provided. That was the last time I heard from him. The forum profile vanished. His phone number stopped working. No response to emails. I was stunned. I couldn’t believe I had been tricked. I didn’t know who to turn to. I felt ashamed and foolish. At my age recovering from a financial loss like this is nearly impossible.My relative stepped in. They searched online for solutions and found TRUST GEEKS HACK EXPERT. I was skeptical at first but they insisted we give them a chance. From the moment we contacted them they treated me with respect patience and genuine concern. Their team didn’t speak in technical riddles. They explained every step. They used blockchain analysis tools to trace the movement of my funds through several addresses.It turned out the wallet was linked to a scam platform. TRUST GEEKS HACK EXPERT worked directly with the USDT issuer and coordinated with relevant platforms to freeze the funds before they were fully laundered.In just two weeks they managed to recover $155000 in USDT.The money helped yes but it was more than that. I no longer felt powerless. I had been taken advantage of but I wasn’t alone in the fight. Thanks to TRUST GEEKS HACK EXPERT I got back not only a large part of my savings but also peace of mind a sense of dignity and hope for the future.

My Wild Ride: How a Wizard Hilton Cyber Tech Helped Me Recover Lost Bitcoin of 103,000 It all started when I had the misfortune of misplacing the digital wallet containing my substantial cryptocurrency holdings - a staggering 103,000 bitcoins. I had amassed this sizable fortune over the years through strategic investments and careful trading, but in a moment of carelessness, the private keys to my digital wallet had vanished. Panic set in as I grappled with the gravity of my situation - those bitcoins, worth millions at the time, were effectively lost to the ether, inaccessible and seemingly unrecoverable. Just when I had resigned myself to the devastating financial blow, a chance encounter with a self-proclaimed "digital wizard" Wizard Hilton Cyber Tech presented a glimmer of hope. This enigmatic individual, who operated in the shadowy corners of the crypto underworld, claimed to possess the arcane knowledge and skills necessary to retrieve my lost digital wealth. Intrigued and desperate, I put my skepticism aside and entrusted this mysterious wizard with the task. What followed was a wild, suspenseful journey into the depths of blockchain technology and cryptography, as the wizard navigated complex algorithms, exploited vulnerabilities, and pieced together the puzzle of my missing private keys. After days of intense effort, Wizard Hilton Cyber Tech emerged triumphant, having successfully recovered the entirety of my 103,000 bitcoin stash. The sheer relief and elation I felt in that moment was indescribable, as I regained access to my small digital fortune and was able to secure my financial future. This harrowing experience taught me the invaluable lesson of never taking the security of my cryptocurrency holdings for granted, and the importance of always maintaining the utmost diligence when it comes to protecting one's digital wealth.

Losing nearly 500,000 USDT to hackers was one of the most devastating experience of my life. I felt powerless as my hard-earned assets vanished into anonymous blockchain transactions until I found Agent Jasmine Lopez. Her deep expertise, tireless effort, and unwavering focus gave me hope and delivered results. She traced complex transactions, pursued every lead, and recovered a large portion of my stolen funds something I never thought possible. If you’ve lost digital assets, don’t give up. Contact Recoveryfundprovider@gmail. com WhatsApp at +{44 736-644-5035}. She turned my nightmare into a recovery story, and she could do the same for you.

I’m a California resident who was contacted by someone named “Lin” on WhatsApp. Our conversation eventually turned to cryptocurrency investments. Lin introduced me to a trading platform called CBOTBIT (https://cbotbit.com), walked me through setting up an account, and guided me on transferring funds. Under Lin’s direction, I began trading and was led to believe that my account was growing significantly. However, when I attempted to withdraw my funds, I was unable to do so — and shortly after, the website went offline entirely. I had invested over $340,000 in Bitcoin, planning to use it for my retirement. The experience was devastating, and I was at a loss for what to do next. Eventually, I came across [email protected] and decided to reach out. I followed their instructions, and within a few days, I was able to recover my original investment. I'm incredibly relieved and grateful for their assistance, and I recommend contacting them if you’re in a similar situation and need help recovering lost funds.

I can honestly say losing my bitcoin savings was one of the darkest moments of my life. I had put everything I could into that investment, believing it would secure my future, only to wake up one day and realize the platform had vanished with all my funds. The feeling was indescribable, fear, shame, and helplessness all at once. I thought I’d never see that money again. Then I came across Alpha Spy Nest. At first, I was hesitant, I had already been deceived once, and the thought of trusting anyone else terrified me. But something about their professionalism and the way they patiently explained things gave me a little hope. For the first time in weeks, I felt like I wasn’t completely alone in the fight. They listened to my story without judgment, broke down the technical side in a way I could understand, and reassured me that there was still a chance. Watching them work was incredible. They traced every transaction, uncovered where my bitcoin had been moved, and kept me updated through every stage. It felt like they cared as much about my recovery as I did. The day they told me they had successfully recovered my lost savings, I actually cried. Seeing those funds back in my wallet felt unreal, it was like a huge weight had been lifted off my shoulders. Beyond just recovering my bitcoin, Alpha Spy Nest gave me back my peace of mind and restored a trust I thought I had lost forever. I’m forever grateful to them. If I hadn’t found Alpha Spy Nest, I’d still be stuck in regret and despair. Instead, I now share my story as proof that recovery is possible.

You are not alone if you have had your bitcoins taken from your wallet or if you invested in an initial coin offering (ICO) that was a scam. I experienced the same thing. I first lost $173,000 to a fraudulent investment scam company in less than five months. I was able to get all of my money in five days thanks to a hacker my friend recommended. In order to raise awareness about these cryptocurrency criminals and do my part to minimize the number of victims, I'm speaking out. To report a victim, simply send an email to [email protected].
