我试图使用通用的Jpa规格与 spring 启动，但出现了这个问题 .
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2018-05-23 18:18:27.340 ERROR 1048 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaSpecificationRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class java.lang.Object.
在我的代码中我正在尝试使用模块概念，所以我有5个模块（实体，dao，服务，web和frontend with angular）所以这是我的代码：
我的通用Jpa规范界面 .
public interface JpaSpecificationRepository<T, ID extends Serializable>
extends JpaRepository<T, ID>, JpaSpecificationExecutor<T> {
}
存储库的例子 .
public interface HelloRepository extends JpaSpecificationRepository<Hello, Long> {
}
服务
@Service
public class HelloServiceImpl extends AbstractCRUDService<Hello, Long, HelloDto> {
@Autowired
protected HelloServiceImpl(HelloRepository repository, DozerBeanMapper mapper) {
super(repository, mapper, Hello.class, HelloDto.class);
}
}
和控制器
@RestController
@CrossOrigin("*")
@RequestMapping("/hello")
public class HelloController extends AbstractCRUDBackOfficeController<Long, HelloDto> {
@Autowired
HelloController(HelloServiceImpl service) {
super(service);
}
}

将
@NoRepositoryBean添加到JpaSpecificationRepository，这样就可以排除此存储库的实例化 .
