springboot中redis操作Hash踩坑解决

 @Override
    public void getSmsCaptcha(String phone) {
        String hashKey = "login:sms:captcha:" + phone;
        BoundHashOperations<String, String, String> hashOps = stringRedisTemplate.boundHashOps(hashKey);
 
        // 初始检查
        String lastSendTimestamp = hashOps.get("lastSendTimestamp");
        String sendCount = hashOps.get("sendCount");
        String captcha = hashOps.get("captcha");
        hashOps.expire(5, TimeUnit.MINUTES); // 设置过期时间为5分钟
       
 
        // 判断发送次数是否超过限制
        if (StringUtils.isNotBlank(sendCount) && Integer.parseInt(sendCount) >= 5) {
            hashOps.expire(24, TimeUnit.HOURS); // 重新设置过期时间为24H
            throw new GeneralBusinessException("发送次数过多，请24H后再试");
        }
 
        // 判断发送频率是否过高
        if (StringUtils.isNotBlank(lastSendTimestamp)) {
            long lastSendTime = Long.parseLong(lastSendTimestamp);
            long currentTime = System.currentTimeMillis();
            long elapsedTime = currentTime - lastSendTime;
            long interval = 60 * 1000; // 60秒
            if (elapsedTime < interval) {
                throw new GeneralBusinessException("发送短信过于频繁，请稍后再试");
            }
        }
 
        // 更新发送次数
        int newSendCount = StringUtils.isNotBlank(sendCount) ? Integer.parseInt(sendCount) + 1 : 1;
 
        // 生成新验证码
        if (StringUtils.isBlank(captcha)) {
            captcha = RandomStringUtils.randomNumeric(6);
        }
 
        // 发送短信
        if (!smsUtil.sendSms(phone, captcha)) {
            throw new GeneralBusinessException("发送短信失败");
        }

    }

BoundHashOperations<String, String, String> hashOps = stringRedisTemplate.boundHashOps(hashKey);
