本文整理了Java中java.time.ZoneId.from()方法的一些代码示例，展示了ZoneId.from()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZoneId.from()方法的具体详情如下：
包路径：java.time.ZoneId
类名称：ZoneId
方法名：from

ZoneId.from介绍

[英]Obtains an instance of ZoneId from a temporal object.

A TemporalAccessor represents some form of date and time information. This factory converts the arbitrary temporal object to an instance of ZoneId.

The conversion will try to obtain the zone in a way that favours region-based zones over offset-based zones using TemporalQueries#zone().

This method matches the signature of the functional interface TemporalQueryallowing it to be used in queries via method reference, ZoneId::from.
[中]从时间对象获取ZoneId的实例。
临时助理代表某种形式的日期和时间信息。该工厂将任意时态对象转换为ZoneId的实例。
转换将尝试使用TemporalQueries#zone（）以支持基于区域的分区而不是基于偏移的分区的方式获取分区。
此方法匹配函数接口TemporalQueryLow的签名，通过方法引用ZoneId:：from将其用于查询。
