java 获取n个工作日后的日期(包含法定节假日、双休日、节后补班)

1.说明:

  获取n个工作日后的日期(包含法定节假日、双休日、节后补班),需要在数据库手动入库当年的法定节假日及节假日调休补班。(也可写在配置文件中读取)

2.工具类代码

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.List;

3.测试调用

public String holiday(String date){
        Date today1 = new Date();
        int num = 10;//
        List<Holiday> holidayList = holidayService.queryAllHoliday("0");//查询出法定节假日list
        List<Holiday> weekDayList =holidayService.queryAllHoliday("1");//查询节假日调休补班list
        
        List hoList = new ArrayList();//节假日数据源
        List weList = new ArrayList();//节后节前数据源
        
        for (Holiday holiday : holidayList) {
            hoList.add(holiday.getDate());
        }
        for (Holiday holiday : weekDayList) {
            weList.add(holiday.getDate());
        }
        try {
            Date date111 = HolidayUtils.getScheduleActiveDate(hoList,weList,today1,num);
            System.out.println(HolidayUtils.parseDate(date111, "yyyy-MM-dd"));
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return "";
    }

4.sql脚本

DROP TABLE IF EXISTS `holiday`;
CREATE TABLE `holiday` (
  `GUID` varchar(36) COLLATE utf8_bin NOT NULL,
  `DATE` varchar(10) COLLATE utf8_bin DEFAULT NULL,
  `TYPE` varchar(1) COLLATE utf8_bin DEFAULT NULL COMMENT '0:法定节假日;1 节假日调休补班(如某个节假日前后周六日上班的情况)',
  PRIMARY KEY (`GUID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='此表需每年根据法定节假日具体时间更新一次';
