java获取法定节假日
**状态1：法定节假日
状态2：周末，但是因为调休而变更为工作日**
如果只是想获取法定节日，可以用这个接口轻松获取2050年之前的信息
很简单，就不上代码了。但是这里只能获取法定节，无法获取法定休息日与调休。
法定休息日与调休一般是国务院在年末公布下一年的安排，所以下面的代码最多也只能获取下一年之前的信息

使用百度日历的接口
查看工作台可以发现数据是从这个接口中获取的
比较可疑的是status这个参数，继续查看百度搜索页面源代码，大概在6000行左右可以发现处理日历的js源代码
格式化一下
很明显，status为1时为节假日，为2时就是改为工作日的休息日。通过观察得知这里面的参数与实际值是差一天的。剩下的代码就很容易了。
