    @ResponseBody
    public String subLogin(user user){
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken
                (user.getUsername(),user.getPassword());
        try {
            subject.login(token);
        }catch (AuthenticationException e){
            return  e.getMessage();

        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken
                (user.getUsername(),user.getPassword());
        try {
            subject.login(token);
        }catch (AuthenticationException e){
            return  e.getMessage();
        }
        return "登录成功";
