方法一 ： 調用第三方接口獲得節假日

周末 + 節假日 -（被調成工作日的日期）= 節假日 這種方式獲得節假日往往需要進行調整，因為每個公司放假時間不一樣，所以還是建議結合第一種方式使用

調用api查詢

方式一：調用api查詢

首先查詢百度萬年歷節接口（其中包含全年節假日數據），得到json數據 （全年節假日信息在json的holiday中，query=2020，其實默認就是202001，其他月份的萬年歷請求如query=202004）

請求的api：

https://sp0.baidu.com/8aQDcjqpAAV3otqbppnN2DJv/api.php?query=2020&resource_id=6018返回的json內容如下，

方法二 ： 代碼運行獲得節假日

周末 + 節假日 -（被調成工作日的日期）= 節假日

1.修改DBhelper數據庫配置文件
2.執行db.sql文件
3.配置getHolidays方法中的法定節假日和調休日期
4.運行com.holiday.GetHolidays 的 main方法

日期格式自定義getHolidays的SEPARATOR參數內容，用20200101或2020-01-01

方法三：直接執行拿2020.sql 日期數據 到自己的數據庫

createDB.sql

2020.sql
