看到网上工作日的工具类不是很完整，整理了一份出来

一、获取几个工作日后的日期

1、先预置国家规定的法定节假日，和调休日（特殊工作日）
2、判断当前日期是否为工作日

二、使用步骤

1.完整代码

代码如下（示例）：

package utils;import cn.hutool.core.date.DateUtil;
import cn.hutool.http.HttpUtil;
import cn.hutool.json.JSONArray;
import cn.hutool.json.JSONObject;
import cn.hutool.json.JSONUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.time.DayOfWeek;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.*;/*** @Desc:* @Author: ding* @Date: 2022/06/08 10:43**/

个人整理的比较粗糙
