关于异步队列的问题
你好，这是你的优化思路：
- 系统初始化，把商品库存数量加载到Redis
- 收到请求，Redis预减库存，库存不足，直接返回，否则进入3
- 请求入队，立即返回排队中
- 请求出队，生成订单，减少库存
- 客户端轮询，是否秒杀成功
第二点，redis预减库存。
经过我的多次实验， redis为单线程，并且减1的操作为原子操作。
redis.opsForValue().increment(key, -1)
那样肯定不会出现超卖的现象。
那么为何还要放到队列异步处理呢？直接处理不是更好，反正都要访问mysql数据库的，
放到队列不是多此一举嘛
期待你的回答，谢谢

你的服务器数据库密码泄露额。提醒一下
测试地址无法访问
测试地址和另外一个地址均无法访问，服务器已经关了？
5.客户端轮询好像没实现?
客户端轮询是使用什么机制?
