偏移日期时间解析

需要从格式解析日期时间2016-06-24T13:39:44.687680.

第一步使用，尝试用线路解析没有微秒的时间。

System.out.println(OffsetDateTime.parse("2011-12-03T10:15:30", DateTimeFormatter.ISO_LOCAL_DATE_TIME));

有例外

Exception in thread "main" java.time.format.DateTimeParseException: Text '2011-12-03T10:15:30' could not be parsed: Unable to obtain OffsetDateTime from TemporalAccessor: {},ISO resolved to 2011-12-03T10:15:30 of type java.time.format.Parsed

尝试使用DateTimeFormatter with TimeZone

System.out.println(OffsetDateTime.parse("2011-12-03T10:15:30", DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.systemDefault())));

类似的例外

OffsetDateTime是日期时间的表示 抵消。 创建一个OffsetDateTime，您需要一个区域偏移。

ISO-8601 日历中与 UTC/格林威治有偏移的日期时间 系统，例如 2007-12-03T10:15:30+01:00。

see: https://docs.oracle.com/javase/8/docs/api/java/time/OffsetDateTime.html https://docs.oracle.com/javase/8/docs/api/java/time/OffsetDateTime.html

例如：

OffsetDateTime.parse("2011-12-03T10:15:30+01:00", DateTimeFormatter.ISO_OFFSET_DATE_TIME);

如果您尝试解析日期时间ZoneId，你应该使用ZonedDateTime.

ISO-8601 日历系统中带有时区的日期时间，例如 2007-12-03T10:15:30+01:00 欧洲/巴黎。

see: https://docs.oracle.com/javase/8/docs/api/java/time/ZonedDateTime.html https://docs.oracle.com/javase/8/docs/api/java/time/ZonedDateTime.html

例如：

ZonedDateTime.parse("2011-12-03T10:15:30", DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.systemDefault()));

如果您需要的是 ISO-8601 日历系统中没有时区的日期时间，您可以使用LocalDateTime.

ISO-8601 日历系统中没有时区的日期时间，例如 如 2007-12-03T10:15:30。

see: https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html

例如：

LocalDateTime.parse("2016-06-24T13:39:44.687680", DateTimeFormatter.ISO_LOCAL_DATE_TIME);
