Java LocalDate使用总结

LocalDate todayDate = LocalDate.now();// 当前日期

System.out.println(todayDate.atStartOfDay(ZoneId.systemDefault()).toInstant().toEpochMilli());// 获取时间戳

LocalDate lastSevenDayDate = todayDate.minusDays(7);// 7天前的日期

System.out.println(lastSevenDayDate);

LocalDate lastMonday = todayDate.with(TemporalAdjusters.previousOrSame(DayOfWeek.MONDAY));// 上周一

System.out.println(lastMonday);

LocalDate lastSunday = todayDate.with(TemporalAdjusters.previousOrSame(DayOfWeek.SUNDAY));// 上周日

System.out.println(lastSunday);

LocalDate lastMonthDay = todayDate.minusMonths(1);// 1个月前日期

System.out.println(lastMonthDay);

// LocalDate转Date
Date date = Date.from(todayDate.atStartOfDay(ZoneId.systemDefault()).toInstant());
