Java 在此ManagedType上找不到具有给定名称[trackers]的属性

我试图为Spring上的应用程序提供实体之间的延迟获取关系

模型“用户”：

继承了带有@EntityGraph的JPA存储库。通过这一点，我试图为select用户提供与以下相关的所有跟踪器：

@Repository
@Transactional(readOnly = true)
public interface CrudUserRepository extends JpaRepository<User, Integer> {

   @EntityGraph (attributePaths = {"trackers"}, type = EntityGraph.EntityGraphType.LOAD)
   @Query("SELECT u FROM User u WHERE u.id=?1")
   User getByIdWithTrackers(int id);
}

和控制器：

@RestController ("userRestController")
@RequestMapping(value = UserRestController.USER_URL, produces = 
MediaType.APPLICATION_JSON_VALUE)
public class UserRestController extends AbstractUserController {

    public static final String USER_URL = "/customers";

    @GetMapping("/{id}")
    public User getByIdWithoutTrackers(@PathVariable int id) {
        return super.getByIdWithoutTrackers(id);
    }

    @GetMapping("/{id}/withTrackers")
    public User getByIdWithTrackers(@PathVariable int id) {
        return super.getByIdWithTrackers(id);
    }
 }

查询“/customers/1”可以正常工作。它返回没有跟踪器的所有客户（相应地，延迟获取）

但是“/customers/1/withTrackers”返回以下异常：

  lang.IllegalArgumentException: Unable to locate Attribute  with the the given name [trackers] on this ManagedType [ru.spb.model.User]"}

哦，这是个愚蠢的错误。在用户界面中，我写“追踪者”。但在CrudUserRepository的AttributePath“追踪者”中

 @Repository
 public class AnketUserRepository implements UserRepository {

   @Autowired
   private CrudUserRepository crudRepository;

   @Override
   public User getByIdWithoutTrackers(int id) {
       return crudRepository.findById(id).orElse(null);
   }

   @Override
   public User getByIdWithTrackers(int id){
       return crudRepository.getByIdWithTrackers(id);
    }

}

@RestController ("userRestController")
@RequestMapping(value = UserRestController.USER_URL, produces = 
MediaType.APPLICATION_JSON_VALUE)
public class UserRestController extends AbstractUserController {

    public static final String USER_URL = "/customers";

    @GetMapping("/{id}")
    public User getByIdWithoutTrackers(@PathVariable int id) {
        return super.getByIdWithoutTrackers(id);
    }

    @GetMapping("/{id}/withTrackers")
    public User getByIdWithTrackers(@PathVariable int id) {
        return super.getByIdWithTrackers(id);
    }
 }

  lang.IllegalArgumentException: Unable to locate Attribute  with the the given name [trackers] on this ManagedType [ru.spb.model.User]"}
