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)

3.测试调用
publicString holiday(String date){
Date today1= newDate();int num = 10;// List holidayList = holidayService.queryAllHoliday("0");//查询出法定节假日list
List 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 "";
}
