How do you implement working with JPA in your projects?

For working with JPA in projects, I usually use the following approach:

• Use Spring Data JPA to simplify database interactions.
• Define entities using annotations like @Entity, @Id, and others to describe the table structure.
• Create repository interfaces extending JpaRepository, which allows using ready-made CRUD methods without implementation.
• For complex queries, apply JPQL or Criteria API, as well as methods with names matching Spring Data patterns.
• Configure the data source and EntityManager via Spring Boot or manually in configuration files.

Example of a simple repository:

public interface UserRepository extends JpaRepository<User, Long> {
    List<User> findByLastName(String lastName);
}

This approach allows for quick and convenient database work, minimizing boilerplate code.
