无秒解析即时

Question

我在字符串中有日期"2015-05-08T02:56"。如您所见，它没有秒。

当我尝试解析它时：

Instant instant = Instant.from(
        DateTimeFormatter.ofPattern("yyyy-MM-dd'T'hh:mm")
                .parse("2015-05-08T02:56"));

我得到异常

Exception in thread "main" java.time.DateTimeException: Unable to obtain Instant from TemporalAccessor: {MinuteOfHour=56, HourOfAmPm=2},ISO resolved to 2015-05-08 of type java.time.format.Parsed

    at java.time.format.Parsed.getLong(Parsed.java:203)
    at java.time.Instant.from(Instant.java:373)
    ... 6 more

如何正确解析此日期并用 填充秒0？

Answer 1

我忘了指定时区

Instant instant = Instant.from(
        DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm")
                .withZone(ZoneId.of("UTC"))
                .parse("2015-05-08T22:57"));

工作正常。

更新：我也有我用另外一个问题hh来代替HH。
