定製MongoDB的查詢與Spring MongoDB的模板

IUserRepository（對於CRUD）

@Transactional 
public interface IUserRepository extends MongoRepository<User, String>, 
    UserRepositoryCustom { 
}

UserRepositoryCustom（對於自定義）

public interface UserRepositoryCustom { 
public User getUserByEmail(String email); 
public User getUserByEmailAndPassword(String email, String password); 
public List<User> getOnlineUsers(); 
}

UserRepositoryImpl（自定義IMPL）

public class UserRepositoryImpl { 

    @Autowired 
    private MongoTemplate mongoTemplate; 

    public User getUserByEmail(String email) { 
     Query searchUserQuery = new Query(Criteria.where("email").is(email)); 
     return mongoTemplate.findOne(searchUserQuery, User.class); 
    } 

    public User getUserByEmailAndPassword(String email, String password) { 
     Query searchUserQuery = new Query(Criteria.where("email").is(email) 
       .andOperator(Criteria.where("password").is(password))); 
     return mongoTemplate.findOne(searchUserQuery, User.class); 
    } 

    public List<User> getOnlineUsers() { 
     Query searchUserQuery = new Query(Criteria.where("online").is(true)); 
     return mongoTemplate.find(searchUserQuery, User.class); 
    } 
}

和服務CRUD實現：

@Repository("userService") 
@Transactional 
public class UserService { 

    @Autowired 
    private IUserRepository userRepository; 

    public List<User> getAll() { 
     return userRepository.findAll(); 
    } 

    public User getUser(String deviceRegistrationID){ 
     return userRepository.findOne(deviceRegistrationID); 
    } 

    public void addUser(User user){ 
     userRepository.save(user); 
    } 

    public User editUser(User user){ 

     User findUser = getUser(user.getDeviceRegistrationID()); 
     findUser.setLatitude(user.getLatitude()); 
     findUser.setLongitude(user.getLongitude()); 
     findUser.setOnline(true); 

     return userRepository.save(findUser);  
    } 
}

當我開始我得到這個錯誤服務器：

我有錯誤，只有當我的CRUD接口實現我的自定義界面了。有什麼問題？

我認爲問題是類和接口的名稱，當你使用彈簧數據時，你需要遵循一些命名規則，以便框架能夠正確理解。

這是確定

public interface IUserRepository extends MongoRepository<User, String>, UserRepositoryCustom {

這是正確的也是>

public interface UserRepositoryCustom {

但實現類有名稱的問題，它應該是

public class IUserRepositoryImpl implements UserRepositoryCustom {

然後春天JPA將工作和存儲庫將被注入服務。
