场景

我们在一些特殊的业务场景下，想要获取到下一个工作日，这里的工作日指正常的法定工作日（包含调休日），这个需求来源于银联的提现，银联只能在法定工作日才能体现，那么在业务代码里对提现日期必须就是工作日即可，在查询了相关的信息，目前没有稳定的API或者三方付费的稳定API，那么这个需求其实不难处理，自己也可以动手维护一套WorkingHolidayAPI的，那么我就以Springboot简答举例写出重要的环节。

Springboot单元测试

调用IWorkingHolidayService.nextWorkingDay(curDate) 即可

原理

实现过程也很简单，因为法定节假日法定工作日长时间是稳定不变，在此基础上，我们先通过以数据表为基础，再以hutool为辅助，来完成近365天的所有法定日的标记，通过维护好的线程安全map我们很快就能获取到具体某一日的下一个工作日是哪一天。

优化项

可以将实时获取到数据库数据的操作改为每天一获取最新的
根据大部分业务来说固定offDay的长度，并注入到容器中
完善其方法，比如下一个休息日等需要的方法

总结

很简单的实现不是么，没有花里胡哨的操作，一起加油
