spring+mvc注解问题。启动报错，求教！！！！！！?报错

spring mvc框架

service层调用DAO层时，代码如下： 

@Component
public class LoginService {
 @Autowired
 private LoginDao loginDao;
 
 public String login(User user){
  return  loginDao.login(user);
 }
}

问题：这个 “@Autowired”会引起启动报错，不加这个注解启动正常，但是调用不到loginDao.login方法

死活查不出原因啊

 

奇怪的是，我在controller层

@Autowired
 private LoginService loginService;

加注解引入service

调用service中的方法完全正常

为什么同样的方式在service中调用dao的就不行了？！？！

跪求高手！！！

 

附上启动报错的代码：
