Provides patterns for Spring Data JPA repositories, entity relationships, queries, pagination, auditing, and transactions.
Creating repositories with CRUD operations, entity relationships, @Query annotations, pagination, auditing, or UUID primary keys.
To implement a repository interface:
Extend the appropriate repository interface:
@Repository
public interface UserRepository extends JpaRepository<User, Long> {
// Custom methods defined here
}
Use derived queries for simple conditions:
Optional<User> findByEmail(String email);
List<User> findByStatusOrderByCreatedDateDesc(String status);
Implement custom queries with @Query:
@Query("SELECT u FROM User u WHERE u.status = :status")
List<User> findActiveUsers(@Param("status") String status);
test cases passed, vs 16 / 23 without
