Java模块 -- 计算工作日 (Excel导入法定假日至数据库 排除周六 周日 法定假日) Calendar

有一个小功能,要求是按照指定时间,计算出规定的工作日,排除国家法定节假日,周日,周六...

网上找了一些案例,但都算不准,但是它们的思路和方法可以借鉴下...于是一边想,一边改...就出来了....

国家法定假日,Java 不可能有专门的API去做调用..

所以,我的思路是,做一个页面,将当年的所有法定假日输入到Excel中,用Excel去导入至数据库,然后从数据库取出数据,去和当前时间进行比较....

Struts2版本     完整项目下载 

SpringMVC版本   完整项目下载     (更新于2016-6-15 )

其实就是Excel上传 不一样,判断工作日还是一样的.....

这个是按照Struts2 上传Excel的....

先看Demo结构图
