谢谢，会看一下的。定时查询的确不妥当。 |
|
这个重启 queue不就清空了吗 |
可以增加一些补偿机制，比如同时存进db中，在延时任务触发的时候，处理成功再删除db的数据，如果你说的这种情况，在重启的时候再重建队列。 |

这里采用简单的queue + 系统重启查询数据库建立queue即可。 |

延时队列检查订单是否已经超期
目前通过定时检查订单未付款情况，如果超时自动取消订单，这种实现的问题就是无法准确时间内取消订单。通过java自带的延时队列，可以准确的实现取消订单的功能，当然如果允许Redis，或者mq也可以在分布式的环境中实现统一的延时队列。项目中定时任务都可以使用延时队列实现准时的任务操作。
