这是dao实现类

@Repository("LoginDao")
public class LoginDaoImpl implements LoginDao {

    @Resource(name = "LoginMapper")
    private LoginMapper LoginMapper;

    public LoginMapper getLoginMapper() {
        return LoginMapper;
    }

    public void setLoginMapper(LoginMapper loginMapper) {
        LoginMapper = loginMapper;
    }

这是service实现类

 @Service("LoginService")
public class LoginServiceImpl implements LoginService {

    @Resource
     private LoginDao LoginDao;

应该是MyBatis的配置文件有错，LoginMapper可能没有配置
