Spring Data JPA: пустой ответ AccessType.Field

0 голосов
/ 06 мая 2020

Spring Boot 2.2.6 Spring Data JPA 2.2.7

Я создал объект и разместил аннотацию поля над полем. Это должно гарантировать, что тип доступа - «поле», но это не так. Если я сделаю запрос, я не получу ошибки, а ответ будет массивом с пустыми объектами. Если я помещаю соответствующий геттер в класс, то все работает. Вы видите, где я что-то забыл?

сущность 

@Entity
@EntityListeners(AuditingEntityListener.class)
@JsonIgnoreProperties(value = {"createdAt", "updatedAt"})
public class Club implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
}

контроллер 

@CrossOrigin
@RestController
@RequestMapping("/api")
public class ClubController {

    @Autowired
    private ClubRepository clubRepository;

    @GetMapping("/clubs")
    List<Club> getAllClubs() {
        return clubRepository.findAll();
    }
}
