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.
PR с MVC тестами
https://github.com/nzinovev/anthropic-claude/pull/11
Итоги
Мы прошли по минимальному циклу разработки, используя ИИ:
Создали БД, таблицы и сущности.
Реализовали взаимодействие с БД через Spring JPA.
Написали CRUD-операции и обработку ошибок.
Добавили юнит-тесты и MVC-тесты.
Впечатления
Справился ли Клод с поставленной задачей?
Да, он выдал рабочий код, который можно было довести до финального состояния.
Написал ли он код уровня сеньора?
Нет. Код требовал исправлений и доработок. Клод допускал ошибки, которые опытный разработчик избежал бы сразу.
Может ли человек без опыта программирования получить такую же выдачу?
Нет, Клод справился только потому, что получал чёткие требования и правильную настройку. ИИ может писать код, но только если задающий понимает, что именно он хочет получить.
ИИ в разработке: помощник или замена?
Можно ли использовать ИИ в реальной работе?
Не просто можно, а нужно. ИИ существенно ускоряет разработку, но важно понимать его ограничения.
Ключевые принципы работы с ИИ
Чем лучше подготовлен промпт, тем лучше выдача
Если промпт размытый – код будет неполным или некорректным.
Если задать чёткий запрос – модель выдаст качественный код.
Чем меньше задача, тем выше качество
ИИ отлично справляется с небольшими блоками кода.
Если же попросить его реализовать большой модуль, он может упустить детали или перегрузить выдачу.
ИИ эффективен как помощник в написании небольших фрагментов кода, но для сложных задач нужен контроль со стороны разработчика.
Риски использования ИИ в разработке
ИИ не гарантирует идеальный код и может нести потенциальные риски.
Не стоит слепо доверять выдаче.
ИИ не анализирует код так, как разработчик. Он может допустить ошибки, которые незаметны сразу, но в будущем приведут к багам.
Конфиденциальность данных.
При работе с большими моделям такими как ChatGPT и Claude нужно быть осторожными с чувствительными и корпоративными данными. Передача кода в публичные LLM-модели несёт риск утечки данных.
Как защитить данные?
Не отправляйте коммерчески важный код в LLM. Если же вы это делаете, обязательно анонимизируйте данные перед отправкой.
Если конфиденциальность критична и анонимизация затруднена, рассмотрите вариант использования локальных LLM. Большой плюс таких моделей, что они локальны, следовательно, ваши данные не покинут просторы вашего ПК.
Нестабильное качество выдачи.
Код от ИИ бывает отличным, средним или откровенно плохим. Качество зависит не от модели, а от того, кто задаёт вопросы. ИИ – мощный инструмент, но бездумное использование может привести к проблемам.
Заменит ли ИИ разработчиков?
Когда-то – возможно. Но точно не сейчас.
ИИ пишет код, но не понимает его так, как человек.
Самая сложная часть разработки – архитектура, бизнес-логика, работа с требованиями – остаются за человеком.
ИИ – не замена, а мощный инструмент. Разработчик, который использует ИИ, будет писать код быстрее, эффективнее и качественнее. Разработчик, который не использует ИИ, будет работать дольше и медленнее.
ИИ – это не враг, а помощник, который ускоряет работу и снимает рутину.
Что дальше?
Мы рассмотрели три из четырёх поставленных вопросов. Осталось ответить на последний, какая модель лучше для программирования? Anthropic Claude? ChatGPT? DeepSeek?
Об этом – в следующей части.
Оставайтесь на связи.

Hello everyone. I’d like to share my personal experience from one of the most challenging times in my life. I’m based in Sydney, Australia, and on November 13, 2025, I fell victim to a fraudulent cryptocurrency investment platform that promised substantial financial growth. Believing their claims, I invested a total of $220,000 with the expectation of earning solid returns. However, when I attempted to withdraw my funds, all communication abruptly stopped. My calls were ignored, my emails went unanswered, and I was left feeling completely powerless. Like many others, I had heard that Bitcoin transactions are impossible to trace, so I assumed my money was lost forever. After some time, I discovered information about GREAT WHIP RECOVERY CYBER SERVICES, a reputable digital asset recovery firm. I decided to reach out to them, and to my astonishment, they were able to help me recover the full amount I had lost. I’m sharing my story in the hope that it may help someone else who is going through a similar situation and looking for support.

I got my money back from the Elon Musk scam. It cost me over 1 BTC and $55,000 in Dogecoin. Scammers vowed to double investments. Their sites seemed real. Fraud was tough to catch early. They hooked me with fast doubles in weeks or months. Videos showed Musk promising giveaways and gains. I bought in. I sent Bitcoin and Dogecoin in bits at first. Small sends worked. Then I wired my full savings. It vanished quick. No answers came. Bank account empty. Bills piled up. Loans covered rent and food. Sleep fled. Stress hit hard. Life crumbled. A friend spotted my trouble. He told of his scam loss last year. Same old plays. He pointed me to Sylvester Bryant, a recovery expert. Email Yt7cracker@gmail. com. WhatsApp +1 512 577 7957 or +44 7428 662701. Sylvester acted fast. He tracked blockchain trails. Dealt with exchanges. Outsmarted the scammers. In weeks, my Bitcoin came back. Even their phony profits too. Debts gone. Life back on track. Got hit? Contact him now.

Hello everyone. I’d like to share my personal experience from one of the most challenging times in my life. I’m based in Sydney, Australia, and on November 13, 2025, I fell victim to a fraudulent cryptocurrency investment platform that promised substantial financial growth. Believing their claims, I invested a total of $220,000 with the expectation of earning solid returns. However, when I attempted to withdraw my funds, all communication abruptly stopped. My calls were ignored, my emails went unanswered, and I was left feeling completely powerless. Like many others, I had heard that Bitcoin transactions are impossible to trace, so I assumed my money was lost forever. After some time, I discovered information about GREAT WHIP RECOVERY CYBER SERVICES, a reputable digital asset recovery firm. I decided to reach out to them, and to my astonishment, they were able to help me recover the full amount I had lost. I’m sharing my story in the hope that it may help someone else who is going through a similar situation and looking for support.

It all started when I decided to explore online trading as a way to grow my savings. Like many, I trusted what appeared to be a legitimate platform, only to find myself trapped in a nightmare. After making consistent trades and finally deciding to withdraw my profits, I was met with silence. My account was suddenly restricted—no warning, no explanation. Every attempt to contact the broker went unanswered or was met with vague, dismissive replies. For three long, agonizing months, I lived in uncertainty. I couldn’t sleep at night. I replayed every email, every transaction, wondering if I’d made a mistake. But deep down, I knew the truth: I hadn’t done anything wrong. The broker had simply decided to lock me out and keep my money. During that time, I felt completely powerless—like I was shouting into a void. The stress affected my health, my relationships, and my ability to focus on anything else. There were days I truly believed that $167,000 was gone forever, lost to the shadows of the unregulated online trading world. I even began to accept it as a painful lesson—one that would cost me dearly but might teach me to be more cautious in the future. But something inside me refused to surrender completely. That’s when I discovered TechY Force Cyber Retrieval. At first, I was cautious—after being scammed once, I didn’t want to fall victim again. But everything about TechY Force felt different. They were transparent from the start. No grand promises, no pressure tactics. Just clear, professional communication and a deep understanding of how these fraudulent brokers operate. Most importantly, they are a licensed specialist in binary options and forex fund recovery, which gave me the confidence to move forward. From our very first consultation, their team treated my case with urgency and empathy. They walked me through the entire process, explained the legal and technical avenues available, and assured me they would handle every detail. They collected documentation, analyzed transaction trails, and engaged directly with the payment processors and the broker using precise, strategic methods I never could have navigated on my own. What happened next was nothing short of miraculous. Within weeks, the broker—who had ignored me for months—began responding. And then, without any further drama or delays, my full $167,000 USD was returned to me. No deductions. No hidden fees. Just clean, complete recovery. The relief I felt was indescribable. It wasn’t just about the money—it was about reclaiming control, restoring trust, and proving that even in the face of deception, there are still good people who fight for what’s right. If you’ve been locked out of your trading account, scammed by a fake investment platform, or had your funds unjustly withheld, please know this: you are not alone, and your money may not be lost forever. Thanks to TechY Force Cyber Retrieval, I got my life back. Their expertise, integrity, and unwavering commitment turned my despair into deliverance. I cannot recommend them highly enough. To anyone reading this in distress: don’t give up. Reach out. Take that step. Because if someone like me—broken, doubtful, and nearly hopeless—can recover every dollar… so can you. WhatsApp them + 156 172 63 697 With heartfelt thanks and renewed hope, — A Recovered and Grateful Client

It's a joy to write this review. Since I began working with Marie at the beginning of 2018, the service has been outstanding. Hackers stole my monies, and I was frightened about how I would get them back. I didn't know where to begin, consequently it was a nightmare for me. But once my friend told me about ([email protected] and whatsap:+1 7127594675), things became simple for me. I'm glad she was able to get my bitcoin back so I could start trading on Binance again!

"In the crypto world, this is great news I want to share. Last year, I fell victim to a scam disguised as a safe investment option. I have invested in crypto trading platforms for about 10yrs thinking I was ensuring myself a retirement income, only to find that all my assets were either frozen, I believed my assets were secure — until I discovered that my BTC funds had been frozen and withdrawals were impossible. It was a devastating moment when I realized I had been scammed, and I thought my Bitcoin was gone forever, Everything changed when a close friend recommended the Capital Crypto Recover Service. Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet.

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

It is a pleasure to write this review. Since I began working with Marie in early 2018, the service has been outstanding. My coins were stolen by hackers, and I was afraid I wouldn't be able to recover them. It was a nightmare for me because I didn't know where to start. But after my friend told me about [email protected] and whatsapp:+1 7127594675, things became simple for me. I'm glad she was able to get my bitcoin back so I could start trading again.

I’ve always believed that sustainability begins at home—not just in how we recycle or conserve energy, but in the very structures we live in. For years, I dreamed of building a zero-waste neighborhood where every house functions like a living ecosystem: solar-powered, water-wise, and crowned with rooftop greenhouses that feed families and filter air. It wasn’t just architecture—it was my vision for a quieter, cleaner future. To make it real, I turned to Bitcoin. Not as a speculative bet, but as a long-term store of value aligned with my values—decentralized, transparent, and independent of broken systems. Over seven years, I poured savings, side income, and relentless discipline into building a $680,000 crypto portfolio. Every coin had a purpose: permits, materials, and community partnerships. My dream had a balance sheet. Then, in one exhausted, distracted moment, it all collapsed. It was November 2025. I was juggling contractor delays, city inspections, and endless design revisions. My nerves were frayed, my coffee pot never empty. When a “Ledger Live Update” notification popped up, I didn’t think twice. The interface looked identical—same logo, same layout. I entered my credentials… and within seconds, the app disappeared. My wallet balance dropped to zero. I sat frozen. My stomach dropped. All that work—years of sacrifice—gone in a blink. The days that followed were dark. I scoured forums, filed reports, and replayed my mistake on loop. Guilt ate at me. How could I have been so careless? My greenhouse renderings sat untouched. My dream felt like a cruel joke. Just when I was ready to walk away, I stumbled upon a newsletter about green innovation. Tucked between articles on carbon-neutral cities and next-gen solar panels was a short feature on *Digital Light Solution*—a specialized team that helps victims of crypto theft recover stolen assets. Skeptical but desperate, I reached out. What followed wasn’t magic—but it was close to it. Their team treated my case with urgency and compassion. They traced the transaction trail, identified the laundering path, and worked with exchanges to freeze what they could. Within weeks, they’d recovered a significant portion of my funds—enough to restart. Today, I’m not just rebuilding my portfolio—I’m breaking ground on my prototype greenhouse. And every beam, every pane of glass, carries the lesson I learned: that even in our most vulnerable moments, there’s still light to be found.

This past January, my world came crashing down. I lost nearly $42,000 of my hard-earned savings to a sophisticated Solana-based crypto scam. At first, it all seemed legitimate: sleek website, professional whitepaper, even glowing testimonials from “investors.” I’d done my homework, or so I thought. The promise of high returns in a volatile market felt like my ticket to financial freedom. For the first few months, everything appeared to be working. My portfolio showed steady gains. I remember checking my wallet balance daily, feeling a mix of pride and relief. I’ve cracked the code to building real wealth. Then, without warning, the platform vanished. Wallet addresses went dead. Support channels disappeared, and my funds were gone in an instant. The emotional fallout was worse than the financial loss. Sleepless nights became the norm. Anxiety gnawed at me constantly. I replayed every decision in my head, blaming myself for being naive. I vowed never to trust anyone again, not influencers, not experts, not even my own judgment. But giving up wasn’t an option. I owed it to myself and to my future to fight back. So I began digging. I scoured Reddit threads, filed reports with blockchain analytics firms, and even contacted local authorities (though they offered little help). The more I searched, the more overwhelmed I became, lost in a labyrinth of technical jargon, dead ends, and predatory recovery services asking for upfront fees. Then, through a survivor’s forum, I stumbled upon TechY Force Cyber Retrieval. Skeptical but desperate, I reached out. What set them apart wasn’t just their expertise; it was their empathy. They didn’t make wild promises. Instead, they walked me through how crypto tracing works, what success looks like, and what realistic timelines are. No pressure. No false hope. Within weeks, their forensic team identified transaction trails linked to the scam wallet. Using on-chain analysis and coordination with exchanges, they flagged suspicious activity and initiated recovery protocols. It wasn’t magic, but it was methodical, transparent, and grounded in real blockchain intelligence. Today, I’m cautiously optimistic. While not all funds have been recovered yet, TechY Force has already secured a significant portion and, more importantly, restored my sense of agency. I’m sleeping again. I’m healing. If you’ve been scammed, know this: you’re not alone, and you’re not foolish. Crypto fraud preys on hope, but that same hope can fuel your comeback. Don’t suffer in silence. Reach out. Ask questions. And never let a scammer steal your future along with your funds. WhatsApp +1(561) 726 3697 Mail. Techyforcecyberretrieval(@)consultant(.)com Telegram (@)TechCyberforc

I am Natasha Williams from Dallas. I want to share my testimony to encourage anyone who has ever fallen victim to a scam or fraud. Some time ago, I was defrauded by some fraudulent cryptocurrency investment organization online, I was a victim and I lost a huge amount of money, $382,000. I felt angry, disappointed and helpless but I refused to give up and stay calm. I came across this agency, GREAT WHIP RECOVERY CYBER SERVICES.. who helped people recover their money from scammers and the testimonies I saw were quite amazing. And I decided to contact them. I gathered every piece of evidence, chats, receipts, account details, and messages and reported the case to the agency, GREAT WHIP RECOVERY CYBER SERVICES. After 73hours of follow up and not losing faith, the fraudster was traced and held accountable and I recovered all my money back. I highly recommend, GREAT WHIP RECOVERY CYBER SERVICES agency if you have ever fallen victim to scammers, you can contact them.

As cryptocurrencies continue to reshape global finance in 2026, the risks have never been higher. From sophisticated phishing campaigns to fake wallet apps and investment scams, millions of investors face the devastating reality of lost or stolen digital assets. When your crypto vanishes, panic sets in—and that's when fraudsters strike again, posing as "recovery experts" to exploit your vulnerability. CONTACTS US Techyforcecyberretrieval(@)consultant(.)com https(://)techyforcecyberretrieval(.)com But there's a legitimate path forward. TECHY FORCE CYBER RETRIEVAL stands as the industry's most trusted crypto recovery company, combining advanced blockchain forensics, global partnerships, and a client-centric approach to help victims reclaim what was stolen. --- Why Recovery Is Possible—With the Right Team Cryptocurrency's decentralized, pseudonymous nature makes asset recovery complex—but not impossible. The blockchain is transparent. Every transaction leaves a trail. The challenge isn't finding the funds—it's having the expertise to follow that trail through mixers, bridges, and exchange deposits before they disappear forever. That's where TECHY FORCE CYBER RETRIEVAL excels. --- Our Proven Recovery Framework We don't believe in shortcuts, false promises, or upfront fees. Our process is built on transparency, forensic precision, and real results. Here's how we work: 1. Case Intake & Initial Assessment You begin by submitting a detailed report: compromised wallet addresses, transaction IDs, timestamps, and any communication with scammers. Our intake team reviews your case within hours to determine immediate next steps. 2. Blockchain Forensic Analysis Our specialists deploy proprietary tracking tools to map the movement of your stolen assets across multiple blockchains. We identify laundering patterns, exchange deposit addresses, and potential freezing points—building a clear investigative roadmap. 3. Global Partner Coordination Through established relationships with regulated exchanges, DeFi protocols, and compliance teams worldwide, we initiate direct communication to flag suspicious transactions and request asset freezes where legally permissible. 4. Legal & Regulatory Engagement When necessary, we collaborate with legal partners and law enforcement agencies to strengthen recovery efforts—especially in cases involving large-scale hacks or organized fraud rings. 5. Recovery Execution & Fund Return Once assets are secured, they're transferred directly to a new, secure wallet of your choice. We never hold your funds. And critically, we operate on a success-only model. You pay nothing unless we recover your assets. 6. Post-Recovery Security Guidance Recovery is only half the battle. We provide personalized recommendations to secure your remaining holdings—from hardware wallet setup to phishing awareness training—so you can move forward with confidence. --- What Sets TECHY FORCE CYBER RETRIEVAL Apart While countless "recovery services" flood the internet, few deliver legitimate results. Here's why we're consistently rated the best crypto recovery company in 2026: - Zero Upfront Fees – We only succeed when you do. No hidden charges. No bait-and-switch tactics. - Advanced Blockchain Intelligence – Our forensic tools track assets across Bitcoin, Ethereum, Solana, and 50+ other networks. - Global Reach – Partnerships with exchanges and regulatory bodies in North America, Europe, and Asia maximize recovery odds. - Client-First Communication – Weekly updates. Clear timelines. No ghosting. - Proven Track Record – Hundreds of successful recoveries in 2025–2026, with millions returned to rightful owners. --- Emerging Trends in 2026: What Victims Need to Know The threat landscape evolves constantly. This year's biggest risks include: - AI-Powered Phishing: Scammers now use deepfake voice and video to impersonate support staff. - Cross-Chain Bridge Exploits: Funds moved between networks are increasingly targeted. - Fake Recovery Services: Fraudsters pose as legitimate firms—always verify credentials before sharing information. TECHY FORCE CYBER RETRIEVAL stays ahead of these threats, continuously updating our tools and strategies to protect and serve our clients. CONTACTS US Techyforcecyberretrieval(@)consultant(.)com https(://)techyforcecyberretrieval(.)com --- Your Next Step If you've lost crypto to a scam, hack, or forgotten credentials, don't let despair—or another fraudster—steal your second chance. TECHY FORCE CYBER RETRIEVAL is accessible, transparent, and ready to help. Reach out today. Let our experts assess your case—and show you that even in 2026, stolen crypto doesn't have to stay lost forever. — TECHY FORCE CYBER RETRIEVAL Advanced Forensics. Global Reach. Your Recovery.

Like many others, I was drawn in by the allure of cryptocurrency and the promise of financial freedom. When I encountered a self-proclaimed "crypto guru" online, his confidence and flashy lifestyle convinced me that he held the key to success. Eager to learn, I parted with $15,000 for his exclusive course, believing it would grant me access to an elite trading group and lucrative market insights. Initially, my excitement was palpable; I truly thought I was on the verge of a breakthrough. However, that enthusiasm quickly curdled into dread. Once inside the group, the dynamic shifted from education to aggressive exploitation. Instead of genuine mentorship, members were relentlessly upsold on fake trading signals that yielded nothing but losses. The pressure escalated when we were encouraged to invest in a supposed "private pool," which required an additional, staggering access fee of $60,000. It was only as I began to notice glaring inconsistencies and a complete lack of real results among the members that the fog lifted. I realized I hadn't joined a community of traders; I had walked into a sophisticated trap designed specifically to prey on newcomers like myself. The realization that the promises of wealth and insider knowledge were nothing more than a façade left me feeling vulnerable, deceived, and financially devastated. The dream of easy returns had turned into a heavy burden of regret. Desperate for a solution and refusing to let the fraudsters win, I began searching for help. That is when I discovered DIGITAL LIGHT SOLUTION, a firm specializing in online fraud investigations. Reaching out to them was the turning point. Their team approached my case with professionalism and empathy, immediately understanding the complexity of the scam. They guided me through the investigation process, uncovering the layers of deception used by the "guru" and his network. Thanks to their expertise and relentless pursuit of justice, I was able to navigate the aftermath of this ordeal with clarity rather than confusion. While the experience was a harsh lesson, connecting with DIGITAL LIGHT SOLUTION restored my hope and proved that there are still allies ready to fight against online exploitation. If you find yourself in a similar situation, do not lose hope—seek professional help immediately.

I spend my days studying the mysteries of the universe, delving into black holes, quantum mechanics, and the nature of time itself. But apparently, the real black hole I should have been concerned about was my own memory. I encrypted my Bitcoin wallet to keep it as secure as possible. The problem? I promptly forgot the password. Classic, right? It didn't help that this wasn't just pocket change I was dealing with. No, I had $190,000 in Bitcoin sitting in that wallet, and my mind had decided to take a vacation, leaving me with absolutely no idea what that password was. The panic set in fast. My brain, which could solve some of the most complex physics equations, couldn't remember a 12-character password. It felt like my entire financial future was being sucked into a black hole, one I'd created myself. Desperate, I tried everything. I thought I could outsmart the system, using every trick I could think of. I tried variations of passwords I thought I might have used, analyzing them through the lens of my own behavioral patterns. I even resorted to good ol' brute force, typing random combinations for hours, hoping that maybe, just maybe, my subconscious would strike gold. Spoiler alert: it didn't. Each failed attempt made me feel more and more like a genius who'd locked themselves out of their own universe. In a final act of desperation, admitting that theoretical physics couldn't crack my own encryption, I contacted TechY Force Cyber Retrieval. From the moment I reached out, the difference was night and day. While I had been flailing in the dark, they approached my case with a precision that rivaled the calculations I do daily. They didn't promise miracles; they promised a methodical, advanced recovery process. Within a surprisingly short timeframe, they utilized specialized tools to bypass the mental block I couldn't overcome. When they finally recovered the wallet and confirmed the full $190,000 was intact and accessible, the relief was indescribable. It was as if I had pulled my financial future back from the event horizon just before it was lost forever. To anyone thinking they are too smart to lose their keys, or too logical to make such a mistake: don't wait until you are staring into the abyss. If you find yourself in a situation where your own memory has become your greatest enemy, trust the experts at TechY Force Cyber Retrieval. They turned my personal black hole into a success story, proving that sometimes, even the brightest minds need a little help to find the light. REACH OUT TO THEM ON MAIL [email protected]

My name is Elizabeth Madison currently living in New York. There was a time I felt completely broken. I had trusted a fraudulent bitcoin investment organization, who turned out to be a fraudster. I sent money, believing their sweet words and promises on the interest rate I will get back in return, only to realize later that I’ve been scammed. On the day of withdrawal there was no money in my account. The pain hit deep. I couldn’t sleep, I kept asking myself how I could have been so careless, meanwhile my mom was battling with a stroke and the expenses were too much. For days, I cried and blamed myself. The betrayal, the disappointment and my mom's health issues all of this stress made me want to give up on life. But one day, I decided that sitting in pain wouldn’t solve anything. I picked myself up and chose to fight for what I lost then I came across GREAT WHIP RECOVERY CYBER SERVICES and saw how he helped people recover their funds from online fraud. I emailed all the transactions and paperwork I had with the fraudulent organization and they helped me recover all my lost money in just five days. If you have ever fallen victim to scammers, contact GREAT WHIP RECOVERY CYBER SERVICES to help you recover every penny you have lost.

In January, my life shifted in a way I never expected. I clicked a trading link given to me by someone I found on Telegram, believing it was legitimate. It looked professional. It felt secure. I trusted it. Until I tried to withdraw my money. Within seconds, everything was gone, transferred into a wallet claiming account without a trace. That was the moment the truth hit me: I had been scammed. The emotional fallout was brutal. For weeks, I couldn’t even speak about it. I thought people would judge me. I thought they’d say I should have known better. Then someone stepped in who changed everything Agent Jasmine Lopez ,She listened without judgment. She treated my fear as real and valid. She traced patterns, uncovered off-chain indicators, and identified wallet clusters linked to a larger scam network. She showed me that what happened wasn’t random it was organized and intentional. For the first time, I felt hope. Hearing that students, parents, and hardworking people had been targeted the same way made me realize this wasn’t stupidity. It was predation. We weren’t careless we were deliberately targeted and manipulated I’m still healing. The experience changed me. But it also reminded me that even in your darkest moment, there can be someone willing to shine a light. Contact her at [email protected] WHATSAPP +44 7478077894

I am Natasha Williams from Dallas. I want to share my testimony to encourage anyone who has ever fallen victim to a scam or fraud. Some time ago, I was defrauded by some fraudulent cryptocurrency investment organization online, I was a victim and I lost a huge amount of money, $382,000. I felt angry, disappointed and helpless but I refused to give up and stay calm. I came across this agency, GREAT WHIP RECOVERY CYBER SERVICES.. who helped people recover their money from scammers and the testimonies I saw were quite amazing. And I decided to contact them. I gathered every piece of evidence, chats, receipts, account details, and messages and reported the case to the agency, GREAT WHIP RECOVERY CYBER SERVICES. After 73hours of follow up and not losing faith, the fraudster was traced and held accountable and I recovered all my money back. I highly recommend, GREAT WHIP RECOVERY CYBER SERVICES agency if you have ever fallen victim to scammers, you can contact them.

I never thought I’d be the one writing one of these stories. You hear about crypto scams, hacks, and lost fortunes, and you think, “That’s for other people. The careless ones.” I was careful. Or so I believed. It started with a sophisticated phishing attack. An email that looked identical to a legitimate exchange notification, a link to “verify my wallet security,” and a moment of distracted panic. I clicked. Within hours, my life savings in Bitcoin—a sum I’d been accumulating for five years—vanished from my private wallet. The transaction hash was a cold, unfeeling tombstone on the blockchain. My stomach dropped into a void. I felt physically ill. The police filed a report, but their knowledge ended at the edge of traditional finance. The exchange offered sympathy but no solutions. I was adrift, utterly hopeless. After weeks of despair, scouring forums in the dead of night, I found a thread mentioning Mighty Hacker Recovery. The name sounded almost too bold, like something from a cheesy movie. But the testimonials were detailed, sober, and from people who sounded just like me: desperate, betrayed, and out of options. With nothing left to lose, I reached out. Their intake process was professional but guarded. They asked for transaction IDs, wallet addresses, and a detailed timeline—no promises, just facts. A consultant named Leo became my point of contact. He had a calm, analytical voice that cut through my panic. “We don’t hack *into* systems,” he explained. “We follow the digital trail. We analyze the attack vector, trace the flow of funds through the blockchain’s transparency, and identify the weak points in the scammer’s own security. Sometimes, it’s about speed and outmaneuvering them before they can launder the assets.” What followed was a tense, silent partnership. I provided every shred of information I had, while Leo’s team worked in the shadows. There were days of silence that felt like years. Then, an update: they’d traced my BTC to a mixing service, a tool scammers use to obfuscate the trail. Mighty Hacker Recovery used advanced blockchain forensic techniques to peel back those layers. They discovered the scammer had made a critical error—a small portion of the funds was sent to a KYC-compliant exchange wallet. That was the chink in the armor. Using the immutable evidence from the blockchain and legal pressure channels they’d established with certain international platforms, they initiated a recovery claim. The process was complex, involving digital affidavits and proof of illicit origin. Three weeks after my first desperate email, Leo called. “We’ve secured a freeze on the destination wallet. The exchange is cooperating. We’re initiating the reversal.” I didn’t dare believe it until I saw it. Two days later, my wallet balance updated. My Bitcoin, minus Mighty Hacker Recovery’s contingency fee, was back. The relief wasn’t euphoric; it was a deep, trembling exhaustion, like waking up from a nightmare. They didn’t perform magic. They applied intense expertise, relentless persistence, and an intricate understanding of both the blockchain’s weaknesses and a scammer’s psychology. They gave me back more than my crypto; they gave me back a sense of agency in a landscape designed to make victims feel powerless. If you’re reading this from your own private hell of loss, know this: the trail never truly disappears. You just need the right team to follow it. For me, that was Mighty Hacker Recovery.

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.
