springmvc+mybatis调用controller报autowired失败

@service、@controller都写了,@service也写在了实现类而不是接口上,controller中autowired标在了set方法上,单元测试中service和serviceImpl没有问题,但页面调用controller却宝座autowired失败找不到对应service网上找了很多问题我都没有,大概是我检查不够仔细?求大神帮助

添加了一下spring配置和web.xml

异常信息:

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void controller.LoginController.setLoginService(service.LoginService); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [service.LoginService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

controller

 @Controller("loginController")
@RequestMapping("/User")
@Component
public class LoginController {

    private LoginService loginService;

    public LoginService getLoginService() {
        return loginService;
    }

    @Autowired
    @Qualifier("loginService")
    public void setLoginService(LoginService loginService) {
        this.loginService = loginService;
    }

    @RequestMapping(value = "/Login",method=RequestMethod.POST)
    public String userLogin(HttpSession session,@RequestParam("userid") String userid,
            @RequestParam("password") String password, @RequestParam("perflg") int perflg,Model model
            ) {
        User user = loginService.Login(userid, password, perflg);

        if (loginService.Login(userid, password, perflg) != null) {
            session.setAttribute("userid", user.getUserId());
            session.setAttribute("username",user.getUserName());
            session.setAttribute("permission", user.getPermission());
            session.removeAttribute("nologin");
            if (perflg == 0) {
                return "adminhome";
            }
            if (perflg == 1) {
                return "goverhome";
            }
            if (perflg == 2) {
                return "compahome";
            }
            if (perflg == 3) {
                return "consehome";
            }
            if (perflg == 4) {
                return "peoplehome";
            }
        }
        model.addAttribute("Lb_alert", "用户名或密码不正确");
        session.setAttribute("nologin", "你还没有登陆.");
        return "forward:/Login";
    }

}

serviceimpl:

 @Service("loginService")
@Transactional
@Component
public class LoginServiceImpl implements LoginService {


    private LoginMapper loginMapper;


    public LoginMapper getLoginMapper() {
        return loginMapper;
    }

    @Autowired

        this.loginMapper = loginMapper;
    }


    @Override
    public User Login(String userid, String password, int perflg){
        return loginMapper.Login(userid, password, perflg);
    }

}

service

 public interface LoginService {

    public User Login(String userid,String password,int perflg);

}

@Autowired
 private LoginService loginService;
 自动注入我记得不要写set和get方法的,只要在定义变量的时候写个注解就行了

canghaizhiyi 这么写也试过,问题还是一毛一样的....

1.检查你的扫描路径是否正确
2.把@component去掉,
3.需要注入的set,get去掉
4.直接用@autowired

canghaizhiyi 呃.....234都试过了并没有效果,扫描路径的问题我检查了很多遍感觉并没有问题,分别是java文件夹下的controller包,service包和mapper包里的东西。我加上了spring配置文件和web.xml的代码,麻烦能帮我确认一下有没有问题么?
