java获取前...天日期(两种方式)

1. 获取前一天日期

if(StringUtils.isBlank(curDate)) {    curDate=DateTime.now().toDateStr();}// 获取前一天日期String date = LocalDate.parse(curDate)                .minusDays(1)                .format(DateTimeFormatter.ofPattern("yyyyMMdd"));

Date dBefore = new Date();SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");Calendar calendar = Calendar.getInstance();calendar.setTime(dBefore);calendar.add(Calendar.DATE, -1);curDate = format.format(calendar.getTime());

2.获取前三个月日期

Date dBefore = new Date();Calendar calendar = Calendar.getInstance();calendar.setTime(dBefore);calendar.add(Calendar.MONDAY, -3);curDate = format.format(calendar.getTime());

if(StringUtils.isBlank(curDate)) {    curDate=DateTime.now().toDateStr();}String date = LocalDate.parse(curDate)                .minusMonths(3)                .format(DateTimeFormatter.ofPattern("yyyyMMdd"));
