springmvc 用拦截器+token防止重复提交

    @RequestMapping(value = "/{id}/details")
    @FormToken(produce = true)
    public Object details(@PathVariable String id, HttpServletRequest request){
        Map<String,Object> map = new HashMap<>();
        GameInfo gameInfo;
        int count;
        try {
            gameInfo = gameInfoService.get(id, -1);
            // 使用此游戏的活动数
            count = activityService.getCountByGid(id);
            gameInfo.setCount(count);
        } catch (TException e) {
            LOGGER.debug("获取指定游戏详情失败！！", e);
            return new MessageEntity.Builder(request).msg("跳转预览页面失败").code(201).success(false)
                    .create();
