注意mapper接口类
import org.apache.ibatis.annotations.Mapper;

@Mapper //mapper注解

public interface UserMapper{

user finUser();

}

这样写完service, 在service里调用mapper就可以增删改查了

@Service

public class UserServiceImpl implements UserService{

@Autowired
private UserMapper mapper;

@Override
public User FindUser( {
User user = mapper.findUser();
return user;
}

}
