尝试使用 Spring Data JPA 实现自定义存储库时遇到一些问题。
我尝试遵循一些这样的参考指南，但我找不到问题： https ://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.custom-implementations
我不知道为什么 Spring 尝试将自定义存储库方法查找为我的实体属性。
spring-boot-starter-data-jpa => 1.5.11.RELEASE
实体：
public class MyEntity {
private Integer id
private String name;
// Getter/Setters...
}
服务：
@Service
public class MyServiceImpl implements MyService {
@Autowired
private MyRepository repository;
//...
public MyDTO customFind(Long id){
return repository.customFind(id);
}
}
存储库：
@Repository
public interface MyRepository extends JpaRepository<MyEntity, Long>, QueryDslPredicateExecutor<MyEntity>, MyCustomRepository {
//no-op
}
自定义存储库：
public interface MyCustomRepository {
List<MyDTO> customFind(Long id);
}
自定义存储库实施：
public class MyCustomRepositoryImpl implements MyCustomRepository {
@Autowired
private EntityManager entityManager;
public List<MyDTO> customFind(Long id){
JPAQuery<EmpregadoEntity> query = new JPAQuery<>(entityManager);
MyDTO myDTO = query... //... JPA query return MyDTO
return myDTO;
}
}
当我运行应用程序时，我得到了 PropertyReferenceException：
例外：
Caused by: org.springframework.data.mapping.PropertyReferenceException: No property customFind found for type MyEntity!
