## When to use this skill
Use this skill whenever the user wants to:
- Define JPA entities with annotations (@Entity, @Id, @Column)
- Create Spring Data repositories (JpaRepository, CrudRepository)
- Use derived query methods, @Query with JPQL/native SQL, and Specifications
- Configure data sources, Hibernate dialect, and transaction management
- Handle pagination, sorting, auditing, and entity graphs
## How to use this skill
### Workflow
1. **Define entities** with JPA annotations and relationship mappings
2. **Create repositories** extending JpaRepository with derived or custom query methods
3. **Configure the data source** in `application.yml` or `application.properties`
4. **Use services** to encapsulate business logic with proper transaction boundaries
### 1. Entity Definition
```java
@Entity
@Table(name = "users")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(nullable = false)
private String name;
@Column(unique = true, nullable = false)
private String email;
@CreatedDate
private LocalDateTime createdAt;
// Getters and setters
}
```
### 2. Repository
```java
public interface UserRepository extends JpaRepository<User, Long> {
Optional<User> findByEmail(String email);
List<User> findByNameContaining(String name);
Page<User> findByNameContaining(String name, Pageable pageable);
@Query("SELECT u FROM User u WHERE u.email = :email")
Optional<User> findByEmailCustom(@Param("email") String email);
}
```
### 3. Service with Transactions
```java
@Service
@Transactional
public class UserService {
private final UserRepository userRepository;
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
}
public User create(String name, String email) {
User user = new User();
user.setName(name);
user.setEmail(email);
return userRepository.save(user);
}
@Transactional(readOnly = true)
public Page<User> search(String name, Pageable pageable) {
return userRepository.findByNameContaining(name, pageable);
}
}
```
### 4. Configuration
```yaml
spring:
datasource:
url: jdbc:postgresql://localhost:5432/mydb
username: postgres
password: password
jpa:
hibernate:
ddl-auto: validate
show-sql: false
properties:
hibernate.format_sql: true
```
## Best Practices
- Watch for N+1 query problems; use `@EntityGraph` or `JOIN FETCH` to control fetch strategy
- Use pagination (`Pageable`) and batch operations for large datasets
- Separate entities from DTOs; never expose JPA entities directly in API responses
- Define clear transaction boundaries; use `@Transactional(readOnly = true)` for read operations
- Use Flyway or Liquibase for schema migrations instead of `ddl-auto: update` in production
