看著不錯,轉載過來
1, 獲取每天的零點
DateTime dt=new DateTime().withMillisOfDay(0);
System.out.println(dt.toString("yyyy-MM-dd HH:mm:ss"));
//結果
2016-09-09 00:00:00
2, 在每天的6:30處理一些東西
DateTime dt=new DateTime().withHourOfDay(6).withMinuteOfHour(30).withSecondOfMinute(0);
System.out.println(dt.toString("yyyy-MM-dd HH:mm:ss"));
//結果
2016-09 -09 06:30:00
3, 在每月的7號的6:30處理一些東西
DateTime dt=new DateTime().withDayOfMonth(7).withHourOfDay(6).withMinuteOfHour(30).withSecondOfMinute(0);
System.out.println(dt.toString("yyyy-MM-dd HH:mm:ss"));
//結果
2016-09-07 06:30:00
4, 在每年的8月的7號的6:30處理一些東西
DateTime dt=new DateTime().withMonthOfYear(8).withDayOfMonth(7).withHourOfDay(6 ).withMinuteOfHour(30).withSecondOfMinute(0);
System.out.println(dt.toString("yyyy-MM-dd HH:mm:ss"));
//結果
2016-08-07 06:30:00
5, 獲取每個月的第一天和最後一天
DateTime dateTime=new DateTime();
System.out.println(dateTime.dayOfMonth().withMinimumValue().dayOfMonth().get());
System.out.println(dateTime.dayOfMonth().withMaximumValue().dayOfMonth().get ());
//結果
1
30
6, 獲取每天的零點的下一天零點
DateTime dt=new DateTime().withMillisOfDay(0).plusDays(1);
System.out.println(dt.toString("yyyy-MM-dd HH:mm:ss"));
7, 獲取日期差
DateTime start=new DateTime(2015,5,4,12,20);
DateTime start=new DateTime(2015,5,4,12,20);
DateTime end=new DateTime(2015,5,6,3,10);
Period period=new Period(start,end);
System.out.println("month:"+period.getMonths());
System.out.println("days:"+period.getDays());
System.out.println("hours:"+period.getHours());
System.out.println("minutes:"+period.getMinutes());
System.out.println("second:"+period.getSeconds());
//結果
month:0
days:1
hours:14
minutes:50
second:0
8, 單獨獲取天,小時,分鐘,秒
DateTime start=new DateTime(2015,5,4,12,20);
DateTime end =new DateTime(2015,5,5,12,00);
System.out.println(Days.daysBetween(start,end).getDays());
System.out.println(Hours.hoursBetween(start,end).getHours());
System.out.println(Minutes.minutesBetween(start,end).getMinutes());
System.out.println(Seconds.secondsBetween(start,end));
9, 時間判斷是否在某個範圍以及獲取時間差的毫秒
DateTime start=new DateTime(2015,5,4,12,20);
DateTime end =new DateTime(2015,5,5,12,00);
Interval interval=new Interval(start,end);
System.out.println(interval.contains(new DateTime(2015,5,5,11,00)));
Duration duration=new Duration(start,end);
System.out.println(duration.getStandardHours());
