这可能有点俗气，但如果你决心使用Java 8的Java .time来实现这一点，这是一个很好的解决方案:

        this.duration = duration;

如果你不想拖进库，使用Formatter或相关的快捷方式就足够简单了。给定整数秒数s:

  String.format("%d:%02d:%02d", s / 3600, (s % 3600) / 60, (s % 60));

下面是在Kotlin中将java.time.Duration转换为一个漂亮的字符串的一行代码:

duration.run {
   "%d:%02d:%02d.%03d".format(toHours(), toMinutesPart(), toSecondsPart(), toMillisPart())
}

示例输出: 120:56:03.004

这是一个可行的选择。

public static String showDuration(LocalTime otherTime){          
    DateTimeFormatter df = DateTimeFormatter.ISO_LOCAL_TIME;
    LocalTime now = LocalTime.now();
    System.out.println("now: " + now);
    System.out.println("otherTime: " + otherTime);
    System.out.println("otherTime: " + otherTime.format(df));

    Duration span = Duration.between(otherTime, now);
    LocalTime fTime = LocalTime.ofNanoOfDay(span.toNanos());
    String output = fTime.format(df);

    System.out.println(output);
    return output;
}

使用

System.out.println(showDuration(LocalTime.of(9, 30, 0, 0)));

产生如下内容:

otherTime: 09:30
otherTime: 09:30:00
11:31:27.463
11:31:27.463

我的库Time4J提供了一个基于模式的解决方案(类似于Apache DurationFormatUtils，但更灵活):

Duration<ClockUnit> duration =
    Duration.of(-573421, ClockUnit.SECONDS) // input in seconds only
    .with(Duration.STD_CLOCK_PERIOD); // performs normalization to h:mm:ss-structure
String fs = Duration.formatter(ClockUnit.class, "+##h:mm:ss").format(duration);
System.out.println(fs); // output => -159:17:01

这段代码演示了处理小时溢出和符号处理的功能，请参见基于模式的持续时间格式化程序的API。
