有很多答案,但我无法找到与我的情况兼容.我需要找到8小时的差异以及日期变化.就像时间大于8小时然后不执行某些事情.

我们有没有LocalDateTime在Java-8中实现相同的方法？

我试过使用以下但无法实现相同的目标.

LocalDateTime fromDateTime = LocalDateTime.of(2017, 07, 07, 07, 00, 55);
LocalDateTime toDateTime = LocalDateTime.now();
LocalDateTime tempDateTime = LocalDateTime.from(fromDateTime);

long years = tempDateTime.until(toDateTime, ChronoUnit.YEARS);
tempDateTime = tempDateTime.plusYears(years);

long months = tempDateTime.until(toDateTime, ChronoUnit.MONTHS);
tempDateTime = tempDateTime.plusMonths(months);

long days = tempDateTime.until(toDateTime, ChronoUnit.DAYS);
tempDateTime = tempDateTime.plusDays(days);

long hours = tempDateTime.until(toDateTime, ChronoUnit.HOURS);
tempDateTime = tempDateTime.plusHours(hours);

long minutes = tempDateTime.until(toDateTime, ChronoUnit.MINUTES);
tempDateTime = tempDateTime.plusMinutes(minutes);

long seconds = tempDateTime.until(toDateTime, ChronoUnit.SECONDS);

System.out.println("" + java.time.Duration.between(tempDateTime, toDateTime).toHours());

System.out.println(years + " years "
        + months + " …
