基于Rdisson实现延时队列，解决支付延时查单、关单方案

1.需求
2.实现方式
3.具体代码

1.需求

下单支付后，支付回调因部分因素不可达，导致订单状态与微信支付状态不一致。此时需要服务端主动查询订单支付状态，进行更改订单状态。

2.实现方式

基于定时任务
每隔30秒启动一次，找出最近10分钟内创建并且未支付的订单，调用微信查单接口核实订单状态。系统记录订单查询的次数，在n次查询之后状态还是未支付成功，则停止后续查询，并调用关单接口关闭订单。
基于延时队列
每隔5秒/30秒/1分钟/3分钟/5分钟/10分钟/30分钟调用查单接口，若查询付款成功，不再执行队列任务，最后一次查询若还是未返回支付成功状态，则停止后续查询，并调用《关单接口》关闭订单。
延时队列实现方式（这里不做详细描述，优缺点自行百度，本文采用redis实现）

delayqueue
RabbitMQ
reids

3.具体代码

新建实体类 DelayQueueJob 与 ScoredSortedItem

            <version>3.10.5</version>
