Spring错误：没有合格的bean用于reposiotry

Question

我不知道为什么我会收到这个错误。以下是类和配置的详细信息。所有类都在org.ew.bonder.device下，我不确定是否必须为DeviceRepository类添加任何注释。

的ROOT.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context

       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- Have Spring servlet handle all static content -->
    <mvc:default-servlet-handler/>
    <mvc:annotation-driven />

    <context:component-scan base-package="org.ew.bonder.device"/>

DeviceServiceImpl

@Service
public class DeviceServiceImpl extends BaseService implements DeviceService{
    private Logger LOG = LoggerFactory.getLogger(DeviceService.class);
    private DeviceRepository deviceRepository;

    @Autowired
    public DeviceServiceImpl(Validator validator, final DeviceRepository deviceRepository) {
        super(validator);
        this.deviceRepository = deviceRepository;
    }

    @Transactional
    public DeviceApi saveDevice(DeviceApi deviceApi) {

        return null;
    }

    @Transactional
    public DeviceApi createDevice(DeviceApi deviceApi) {
         LOG.info("Validating device request.");    
         validate(deviceApi);
         Device device = new Device(deviceApi);
         deviceRepository.save(device);
         return null;
    }

}

DeviceRepository.java

public interface DeviceRepository extends MongoRepository<Device, String>  {

    @Query("select d from Device d where ownerid = ?")
    DeviceApi findByOwnerid(String ownerid);

}

您必须将@EnableMongoRepositories添加到配置类，或者在您的情况下使用等效的XML：<mongo:repositories base-package="base.pkg.for.repositories" />
