写了一个获取全年的节假日非工作日，2019年节假日的工具类
说明文档
获取全年的节假日非工作日
方式一：调用api查询
http://api.goseek.cn/Tools/holiday?date=20180430
{“code”:10000,“data”:2}
返回数据：工作日对应结果为 0, 休息日对应结果为 1, 节假日对应的结果为 2
那么只要是0，就是工作日，for循环遍历全年的就可以了，但是每个公司会有不同的情况需要定制或者假期长度不一致，所以只能作为一个参考，
方式二：手动去维护部分数据
1.修改DBhelper数据库配置文件
2.执行sql文件
3.配置getHolidays方法中的法定节假日和调休日期
4.运行main方法
日期格式自定义，用20190101或2019-01-01
