在Java8中使用Timezone格式化LocalDateTime [英] Format LocalDateTime with Timezone in Java8
本文介绍了在Java8中使用Timezone格式化LocalDateTime的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有这个简单的代码:
DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss.SSSSSS Z");
LocalDateTime.now().format(FORMATTER)
然后我会得到以下异常:
Then I will get following exception:
java.time.temporal.UnsupportedTemporalTypeException: Unsupported field: OffsetSeconds
at java.time.LocalDate.get0(LocalDate.java:680)
at java.time.LocalDate.getLong(LocalDate.java:659)
at java.time.LocalDateTime.getLong(LocalDateTime.java:720)
at java.time.format.DateTimePrintContext.getValue(DateTimePrintContext.java:298)
at java.time.format.DateTimeFormatterBuilder$OffsetIdPrinterParser.format(DateTimeFormatterBuilder.java:3315)
at java.time.format.DateTimeFormatterBuilder$CompositePrinterParser.format(DateTimeFormatterBuilder.java:2182)
at java.time.format.DateTimeFormatter.formatTo(DateTimeFormatter.java:1745)
at java.time.format.DateTimeFormatter.format(DateTimeFormatter.java:1719)
at java.time.LocalDateTime.format(LocalDateTime.java:1746)
如何解决此问题?
推荐答案
LocalDateTime
是没有时区的日期时间。您以格式指定了时区偏移格式符号,但是, LocalDateTime
没有此类信息。这就是发生错误的原因。
LocalDateTime
is a date-time without a time-zone. You specified the time zone offset format symbol in the format, however, LocalDateTime
doesn't have such information. That's why the error occured.
如果你想要时区信息,你应该使用 ZonedDateTime
。
If you want time-zone information, you should use ZonedDateTime
.
DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss.SSSSSS Z");
ZonedDateTime.now().format(FORMATTER);
=> "20140829 14:12:22.122000 +09"
