NoUniqueBeanDefinitionException引发应用程序

Question

我必须对所有常见的休眠方法（例如保存，更新，查找等）使用公共的dao类。为此，我创建了一个BaseDao实现，并且所有childDao实现都对该类进行了扩展。但是当应用程序运行时，它抛出{{1 }}。 我使用了NoUniqueBeanDefinitionException注释来解决此问题，但没有用。可能以我的经验较少，请为该问题提供解决方案。

@Qualifier

和扩展BaseDao的第二个childDao是

    @RestController
public class DeviceRestController {
        @Autowired
        EncryptionUtils encryptionUtils;
        @Autowired
        private Environment env;
        @Autowired
        MasterDeviceServiceImpl masterDevice;
        ....}

@Service
@Transactional
public class MasterDeviceServiceImpl extends BaseServiceImpl implements MasterDeviceService {

    @Autowired
    MasterDeviceDao masterDeviceDao;

    public List<BatchDetails> getAllBatchDetails() {
        return masterDeviceDao.getAllBatchDetails();
    }

    public void addMasterDeviceDetails(MasterDevices masterDevice) {
        masterDeviceDao.addMasterDeviceDetails(masterDevice);

    }












@Service
public interface MasterDeviceService {

    public List<BatchDetails> getAllBatchDetails();

    public void addMasterDeviceDetails(MasterDevices masterDevice);

    public List<MasterDevices> getAllMasterDevicesDetails();

    public List<MasterDevices> getMasterDevicesDetails(String deviceKey);


}






public interface MasterDeviceDao {
    public List<BatchDetails> getAllBatchDetails();

    public void addMasterDeviceDetails(MasterDevices masterDevice);

    public List<MasterDevices> getAllMasterDevicesDetails();

    public List<MasterDevices> getMasterDevicesDetails(String deviceKey);
}








@Repository
public class MasterDeviceDaoImpl extends BaseDaoImpl implements MasterDeviceDao {

    @Autowired
    private HibernateTemplate template;

    @Autowired
    SessionFactory sessionFactory;

    protected Session getSession() {
        return sessionFactory.getCurrentSession();
    }

    public List<BatchDetails> getAllBatchDetails() {
        List<BatchDetails> batchDetails = template.loadAll(BatchDetails.class);
        return batchDetails;
    }

基类实现是

@RestController
@PropertySource({ "classpath:childCar.properties" })
public class GeneralRestController {
    @Autowired
    private Environment env;
    @Autowired
    EncryptionUtils encryptionUtils;
    @Autowired
    DateTimeUtils dateTimeUtils;
    @Autowired
    CountryService countryService;
    @Autowired
    UsersService usersService;
.....}




@Service
public interface UsersService {
    public List<Countries> getAllCountries();

    public List<Countries> getAllCountriesbBydate(Timestamp date);

    public Users getUserDetails(int id);
.........}

public interface UsersDao {
    public List<Countries> getAllCountries();

    public List<Countries> getAllCountriesbBydate(Timestamp date);

    public Users getUserDetails(int id);
.............}




@Service
@Transactional
public class UsersServiceImpl extends BaseServiceImpl implements UsersService{
    @Autowired

    UsersDaoImpl usersDao;


    public List<Countries> getAllCountries() {
        return usersDao.getAllCountries();
    }

    public List<Countries> getAllCountriesbBydate(Timestamp date) {
        return usersDao.getAllCountriesbBydate(date);
    }

..............}





@Repository

public class UsersDaoImpl extends BaseDaoImpl implements UsersDao {

    @Autowired
    private HibernateTemplate template;
    @Autowired
    SessionFactory sessionFactory;

    protected Session getSession() {
        return sessionFactory.getCurrentSession();
    }

    public List<Countries> getAllCountries() {
        return template.loadAll(Countries.class);
    }
.....}

例外是

@Repository
public abstract class BaseDaoImpl implements BaseDao {

    @Autowired
    private HibernateTemplate template;
    @Autowired
    SessionFactory sessionFactory;

    protected Session getSession() {
        return sessionFactory.getCurrentSession();
    }
    public <T> void updateObject(T entity) {
        getSession().update(entity);
    }
.........}








    public interface BaseDao {
        public <T> void updateObject(T entity);  

        public <T> List<?> getObject(Class<?> s, int id);

        public void saveObject(Object obj);
    }





@Service
@Transactional
public abstract class BaseServiceImpl implements BaseService {
    @Autowired
    BaseDao baseDao;

    public <T> void updateObject(T entity) {

        baseDao.updateObject(entity);
    }

    public <T> List<?> getObject(Class s, int id) {

        return baseDao.getObject(s, id);

    }

    public void saveObject(Object obj) {
         baseDao.saveObject(obj);
    }

}


@Service
public interface BaseService {
    public <T> void updateObject(T entity);

    public <T> List<?> getObject(Class s, int id);

    public void saveObject(Object obj);
}
