基于@siddhadev的回答，我写了一个将毫秒转换为格式化字符串的函数:

   /**
     * Convert a millisecond duration to a string format
     * 
     * @param millis A duration to convert to a string form
     * @return A string of the form "X Days Y Hours Z Minutes A Seconds".
     */
    public static String getDurationBreakdown(long millis) {
        if(millis < 0) {
            throw new IllegalArgumentException("Duration must be greater than zero!");
        }

        long days = TimeUnit.MILLISECONDS.toDays(millis);
        millis -= TimeUnit.DAYS.toMillis(days);
        long hours = TimeUnit.MILLISECONDS.toHours(millis);
        millis -= TimeUnit.HOURS.toMillis(hours);
        long minutes = TimeUnit.MILLISECONDS.toMinutes(millis);
        millis -= TimeUnit.MINUTES.toMillis(minutes);
        long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);

        StringBuilder sb = new StringBuilder(64);
        sb.append(days);
        sb.append(" Days ");
        sb.append(hours);
        sb.append(" Hours ");
        sb.append(minutes);
        sb.append(" Minutes ");
        sb.append(seconds);
        sb.append(" Seconds");

        return(sb.toString());
    }

我认为最好的办法是:

String.format("%d min, %d sec", 
    TimeUnit.MILLISECONDS.toSeconds(length)/60,
    TimeUnit.MILLISECONDS.toSeconds(length) % 60 );

嗯……一秒是多少毫秒?一分钟后呢?除法没那么难。

int seconds = (int) ((milliseconds / 1000) % 60);
int minutes = (int) ((milliseconds / 1000) / 60);

这样持续几小时、几天、几周、几个月、一年、几十年，等等。

我修改了@MyKuLLSKI的回答，增加了多元化支持。我去掉了几秒，因为我不需要它们，如果你需要的话，可以重新添加。

public static String intervalToHumanReadableTime(int intervalMins) {

    if(intervalMins <= 0) {
        return "0";
    } else {

        long intervalMs = intervalMins * 60 * 1000;

        long days = TimeUnit.MILLISECONDS.toDays(intervalMs);
        intervalMs -= TimeUnit.DAYS.toMillis(days);
        long hours = TimeUnit.MILLISECONDS.toHours(intervalMs);
        intervalMs -= TimeUnit.HOURS.toMillis(hours);
        long minutes = TimeUnit.MILLISECONDS.toMinutes(intervalMs);

        StringBuilder sb = new StringBuilder(12);

        if (days >= 1) {
            sb.append(days).append(" day").append(pluralize(days)).append(", ");
        }

        if (hours >= 1) {
            sb.append(hours).append(" hour").append(pluralize(hours)).append(", ");
        }

        if (minutes >= 1) {
            sb.append(minutes).append(" minute").append(pluralize(minutes));
        } else {
            sb.delete(sb.length()-2, sb.length()-1);
        }

        return(sb.toString());          

    }

}

public static String pluralize(long val) {
    return (Math.round(val) > 1 ? "s" : "");
}

DurationFormatUtils.formatDurationHMS(长)

我在另一个答案中提到了这一点，但你可以这样做:

public static Map<TimeUnit,Long> computeDiff(Date date1, Date date2) {
    long diffInMillies = date2.getTime() - date1.getTime();
    List<TimeUnit> units = new ArrayList<TimeUnit>(EnumSet.allOf(TimeUnit.class));
    Collections.reverse(units);
    Map<TimeUnit,Long> result = new LinkedHashMap<TimeUnit,Long>();
    long milliesRest = diffInMillies;
    for ( TimeUnit unit : units ) {
        long diff = unit.convert(milliesRest,TimeUnit.MILLISECONDS);
        long diffInMilliesForUnit = unit.toMillis(diff);
        milliesRest = milliesRest - diffInMilliesForUnit;
        result.put(unit,diff);
    }
    return result;
}

输出类似Map:{DAYS=1, HOURS=3, MINUTES=46, SECONDS=40, MILLISECONDS=0, MICROSECONDS=0, NANOSECONDS=0}，单位是有序的。

由您决定如何根据目标语言环境对这些数据进行国际化。
