        //方法一

        long milliSecondsLeftToday = 86400000 - DateUtils.getFragmentInMilliseconds(Calendar.getInstance(), Calendar.DATE);

        long secondsLeftToday = 86400 - DateUtils.getFragmentInSeconds(Calendar.getInstance(), Calendar.DATE);

        System.out.println("当天剩余毫秒1：" + milliSecondsLeftToday);

        System.out.println("当天剩余秒1：" + secondsLeftToday);

        //方法二

        DateTime dateTime = new DateTime().millisOfDay().withMaximumValue();

        long millSeconds2 = new Duration(new DateTime(), dateTime).getMillis();

        long count = new Duration(new DateTime(), dateTime).getStandardSeconds();

        System.out.println("当天剩余毫秒2：" + millSeconds2);

        System.out.println("当天剩余秒2：" + count);

        //方法三:LocalDateTime和ChronoUnit为1.8新增

        LocalDateTime midnight = LocalDateTime.now().plusDays(1).withHour(0).withMinute(0).withSecond(0).withNano(0);

        long millSeconds = ChronoUnit.MILLIS.between(LocalDateTime.now(),midnight);

        long seconds = ChronoUnit.SECONDS.between(LocalDateTime.now(), midnight);

        System.out.println("当天剩余毫秒3：" + millSeconds);

        System.out.println("当天剩余秒3：" + seconds);

    }
