spring 引导应用程序中的存储库无法识别@Autowired 注释

Question

我创建了一个小型 spring 启动项目，它将进行数据库交互，我正在使用 @Controller、@Service 和 @Repository。

spring boot main class 在父包 com.bisnu.main 中，然后控制器、服务和存储库在父包下 com.bisnu.main.service...

一切都很好，但是 @Autowired 对于存储库，它无法为存储库创建 bean，它给出错误。

@EnableSwagger2
@RestController
@CrossOrigin(origins="*",allowedHeaders="*")
@RequestMapping("/TestController")
public class TestController {

    @Autowired
    private SourceService sourceService;

    @GetMapping("/getSourcelist")
    public List<SourceListDTO> getAllTelevisionSource(){
        List<SourceListDTO> televisionSource = null;

        televisionSource = sourceService.getTelevisionSource();
        return televisionSource;
    }

}


@Service
public class SourceService {

    @Autowired
    private TestRepository testRepo;

    public List<SourceListDTO> getTelevisionSource() {
        Pageable pageable = PageRequest.of(0, 100);
        List<SourceListDTO> list = testRepo.findSourceList(pageable);
        return list;
    } 
}


public interface TestRepository extends JpaRepository<MyTelevisionSource,Long> {
    @Query("select query")
    List<SourceListDTO> findSourceList(Pageable pageable);
}

我遇到了以下错误，

Field testRepo in com.tivo.extract.core.service.SourceService required a bean of type 'com.tivo.extract.core.repository.TestRepository' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.tivo.extract.core.repository.TestRepository' in your configuration.

谁能指导一下，这是怎么回事。

谢谢

将 @Repository 注释添加到 class

@Repository
public interface TestRepository extends JpaRepository<MyTelevisionSource,Long> {
   ...

并在主 class（标有 @SpringBootApplication）或任何标有 @Configuration 的 class

中添加以下注释

@SpringBootApplication
@EnableJpaRepositories(basePackages = {"com.example.repositories"})
@EntityScan("com.example.entities")
public class BootApplication {
    ...

spring 引导应用程序中的存储库无法识别@Autowired 注释

@Autowired annotation is not recognized for repository in spring boot application

autowired
