如何将服务和存储库自动连接在一起

Question

我必须修复以下错误。任何人都可以帮忙

严重：StandardWrapper.Throwable org.SpringFramework.Beans.Factory.BeanCreationException：创建名为“Search Controller”的bean时出错：注入autowired依赖项失败；嵌套异常为org.springframework.beans.factory.beanCreationException：无法自动连接方法：public void com.website.dev.controller.searchcontroller.setRecordingService（com.website.dev.service.RecordingService）；嵌套异常为org.springframework.beans.factory.noSuchBeanDefinitionException：未找到依赖项得[com.website.dev.service.recordingservice]类型得合格bean：需要至少一个符合此依赖项自动候选条件得bean.依赖项批注：{}

@Controller
public class SearchController {

    private RecordingService recordingService;

    @Autowired
    public void setRecordingService(RecordingService recordingService) {
        this.recordingService = recordingService;
    }

    @RequestMapping("/search")
    public String showSearch(){
        return "search";
    }
}

@Service("recordingService")
public interface RecordingService  {

    //methods
}


public class RecordingServiceImpl implements RecordingService  {

    @Autowired
    private RecordingRepository recordingRepository;

    //methods that use recordingRepository
}

public interface RecordingRepository {


}

@Repository
public class RecordingJpaRepository implements RecordingRepository {

    @PersistenceContext
    private EntityManager entityManager;

   //methods that use entityManager
}

<context:annotation-config></context:annotation-config>
        <context:component-scan
           base-package="com.website.dev.service">
        </context:component-scan>
</beans>

<context:component-scan 
    base-package="com.website.dev.controller"> // searchcontroller is in this package
</context:component-scan>

<context:component-scan 
    base-package="com.enepath.dev.controller">
</context:component-scan>

如果自动调用RecordingServiceImpl,则会得到以下信息

org.springframework.beans.factory.BeanCreationException：创建名为“Recording ServiceImpl”的bean时出错：注入autowired依赖项失败；嵌套异常为org.springframework.beans.factory.beanCreationException：无法自动连接字段：private com.website.dev.repository.recordingrepository com.website.dev.service.recordingserviceimpl.recordingrepository；嵌套异常为org.springframework.beans.factory.noSuchBeanDefinitionException：未找到依赖项得[com.website.dev.repository.recordingrepository]类型得合格bean：需要至少一个符合此依赖项自动候选条件得bean.依赖项注释：{@org.SpringFramework.Beans.Factory.Annotation.AutoWired(required=true)}

我在service-context.xml中添加了以下配置，从而解决了我的问题

   <context:annotation-config></context:annotation-config>
   <context:component-scan
        base-package="com.website.dev.service">
    </context:component-scan>
    <context:component-scan 
        base-package="com.website.dev.repository">
    </context:component-scan>
    <context:component-scan 
        base-package="com.website.dev.repository.jpa">
    </context:component-scan>
