定时查询未支付单，进行处理：

已支付更新状态。
未支付视情况通知支付。

定时任务实现：

在入口类添加注解：

   @EnableScheduling

在要执行的方法上添加

@Scheduled(cron = "0 * * * * ? ")
// 秒 分 时 日 月 周

* 表示所有值。例如:在分的字段上设置 *,表示每一分钟都会触发。
? 表示不指定值。使用的场景为不需要关心当前设置这个字段的值。例如:要在每月的 10 号触发一个操作，但不关心是周几，所以需要周位置的那个字段设置为”?” 具体设置为 0 0 0 10 * ?
- 表示区间。例如在小时上设置 “10-12”,表示 10,11,12 点都会触发。
, 表示指定多个值，例如在周字段上设置 “MON,WED,FRI” 表示周一，周三和周五触发
/ 用于递增触发。如在秒上面设置”5/15” 表示从 5 秒开始，每增 15 秒触发 (5,20,35,50)。在日字段上设置’1/3’所示每月 1 号开始，每隔三天触发一次。
L 表示最后的意思。在日字段设置上，表示当月的最后一天(依据当前月份，如果是二月还会依据是否是润年[leap]), 在周字段上表示星期六，相当于”7”或”SAT”。如果在”L” 前加上数字，则表示该数据的最后一个。例如在周字段上设置”6L”这样的格式,则表示“本月最后一个星期五”
W 表示离指定日期的最近那个工作日(周一至周五). 例如在日字段上置”15W”，表示离每月 15 号最近的那个工作日触发。如果 15 号正好是周六，则找最近的周五(14 号)触发, 如果 15 号是周未，则找最近的下周一(16 号)触发.如果 15 号正好在工作日(周一至周五)，则就在该天触发。如果指定格式为 “1W”,它则表示每月 1 号往后最近的工作日触发。如果 1 号正是周六，则将在 3 号下周一触发。(注，”W”前只能设置具体的数字,不允许区间”-“)。
# 序号(表示每月的第几个周几)，例如在周字段上设置”6#3”表示在每月的第三个周六.注意如果指定”#5”,正好第五周没有周六，则不会触发该配置(用在母亲节和父亲节再合适不过了) ；小提示：’L’和 ‘W’可以一组合使用。如果在日字段上设置”LW”,则表示在本月的最后一个工作日触发；周字段的设置，若使用英文字母是不区分大小写的，即 MON 与 mon 相同。
