没有HttpServletRequest作为入参,但是要获取头部等请求相关的信息,如下

    @RequestMapping("/a")
    @ResponseBody
    @LoginRequired(jwtToken = "1")
    public Object logintest() {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        System.out.println(request.getHeader("jwtToken"));
        return "测试登录验证注解时候生效";

    }
