教你怎么⽤Java获取国家法定节假⽇
前⾔
此节假⽇为严格按照国家要求的双休和法定节假⽇并且包含节假⽇的补班信息，⼤家可根据⾃⼰的需求⾃定义处理哦。以下为Maven配置，是程序⽤到的依赖。版本的话，可以⽤最新的。
Maven配置
<!-- okhttp -->
<dependency>
<groupId>com.squareup.okhttp</groupId>
<artifactId>okhttp</artifactId>
<version>${okhttp.version}</version>
</dependency>
<!-- fastjson -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>${fastjson.version}</version>
</dependency>

return dateList;fastjson怎么用
}
}
以上⽅法可以拿来即⽤，当然也可以根据⾃⼰的需求⾃定义。
以下是我⾃⼰业务需求，将调⽤API接⼝获取的节假⽇信息保存到本地数据库中，如果不感兴趣可以跳过以下内容哦~~~~ package com.uiotsoft.daily.task;
