Joda Time

取整天的方法

    DateTime now = new DateTime(); // 2016-02-26T16:51:28.749+08:00
    now.dayOfWeek().roundCeilingCopy(); // 2016-02-27T00:00:00.000+08:00
    now.dayOfWeek().roundFloorCopy(); // 2016-02-26T00:00:00.000+08:00
    now.minuteOfDay().roundFloorCopy(); // 2016-02-26T16:51:00.000+08:00
    now.secondOfMinute().roundFloorCopy(); // 2016-02-26T16:51:28.000+08:00

两个时间相差多少天

    DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss");
    DateTime date1 = dateTimeFormatter.parseDateTime("2020-07-30 23:00:00").dayOfWeek().roundFloorCopy();
    Date date = new Date();
    DateTime date2 = new DateTime(date).dayOfWeek().roundFloorCopy();
    System.out.println("时间2："+date2.toString("yyyy-MM-dd HH:mm:ss"));
    System.out.println("时间1："+date1.toString("yyyy-MM-dd HH:mm:ss"));
    System.out.println("时间相差："+ Days.daysBetween(date1,date2).getDays()+" 天 " );
