本类依赖commons-lang包java日期计算简单实用方法如下：SimpleDateFormatformat=newSimpleDateFormat("yyyy-MM-dd");WorkdayUtilsworkdayUtils=newWorkdayUtils();workdayUtils.setLegalWorkdayList(legalWorkdayList);workdayUtils.setLegalHolidayList(legalHolidayList);//计算15个工作日之后的工作日日期Datedate=workdayUtils.getWorkday(newDate(),15);/
