1.說明：
獲取n個工作日后的日期（包含法定節假日、雙休日、節后補班），需要在數據庫手動入庫當年的法定節假日及節假日調休補班。（也可寫在配置文件中讀取）
2.工具類代碼

3.測試調用
public String holiday(String date){ Date today1 = new Date(); int num = 10;// List<Holiday> holidayList = holidayService.queryAllHoliday("0");//查詢出法定節假日list List<Holiday> weekDayList =holidayService.queryAllHoliday("1");//查詢節假日調休補班list List hoList = new ArrayList();//節假日數據源 List weList = new ArrayList();//節后節前數據源 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 ""; }
