I have entity class representing post as below.

@Entity
@Getter
@Setter
public class Post {
  @Id
  private long id;
  private String title;
  private String content;
  private LocalDateTime created;
}

When I use jpaRepository to findAll posts I receive list of empty elements.

Empty post response

JpaRepository code :

@Repository
public interface PostRepository extends JpaRepository<Post, Long> {}

PostService :

@Service
public class PostService {

@Autowired
private PostRepository postRepository;

   public List<Post> getPosts() {
   return postRepository.findAll();
}
}

I found that Hibernate propably cannot set values of Post that's why I got list of empty elements. If I change post properties to public, everything works fine but I want to keep they private. I guess @Setter annotation doesn't work and hibernate can't parse data into Post objects.

Can someone know how to fix it?

change long to Long on entity level

Try to use the below annotations instead:

@NoArgsConstructor
@Getter
@Setter
