How to autowire a service and a repository together

I have to fix the following error. Anyone can help

SEVERE: StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'searchController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void com.website.dev.controller.SearchController.setRecordingService(com.website.dev.service.RecordingService); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.website.dev.service.RecordingService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

@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
}

service-context.xml

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

website-servlet.xml

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

web.xml

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

EDIT

If I autowire RecordingServiceImpl I get the following

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'recordingServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.website.dev.repository.RecordingRepository com.website.dev.service.RecordingServiceImpl.recordingRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.website.dev.repository.RecordingRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

I added the following configuration in service-context.xml and this solved my issue

   <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>

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.website.dev.service.RecordingService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

If we look above exception, we will find that spring container is unable to create or instantiate the bean of type com.website.dev.service.RecordingService.

It is because POJO class is not managed by spring container.

@Autowire annotation will work only those objects which are managed by spring (ie created by the spring container).

you should annotate the RecordingServiceImpl class as Service

@Service
public class RecordingServiceImpl implements RecordingService

and remove @Service("recordingService") from

public interface RecordingService  {

    //methods
}

RecordingServiceImpl would be managed by Spring container and spring would be able to create the bean.
