Использовал ли JPA с Hibernate

@Entity
@Table(name = "users")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(name = "username")
    private String username;
    
    // Геттеры и сеттеры
}

EntityManagerFactory emf = Persistence.createEntityManagerFactory("my-pu");
EntityManager em = emf.createEntityManager();

em.getTransaction().begin();
User user = new User();
user.setUsername("JohnDoe");
em.persist(user);
em.getTransaction().commit();

em.close();
emf.close();
