 @Transactional
    public void checkRepeat(String name, String userId) {
        String check_repeat = "repeat::%s::%s";
        String key = String.format(check_repeat, name, userId);
        boolean bool = redisTemplate.opsForValue().setIfAbsent(key, "1");
        if (bool) {
            redisTemplate.expire(key, 5, TimeUnit.SECONDS);
        } else {
            throw new RepeatException();
        }
