本文整理了Java中org.joda.time.format.DateTimeFormatter.withChronology()方法的一些代码示例，展示了DateTimeFormatter.withChronology()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。DateTimeFormatter.withChronology()方法的具体详情如下：
包路径：org.joda.time.format.DateTimeFormatter
类名称：DateTimeFormatter
方法名：withChronology

DateTimeFormatter.withChronology介绍

[英]Returns a new formatter that will use the specified chronology in preference to that of the printed object, or ISO on a parse.

When printing, this chronolgy will be used in preference to the chronology from the datetime that would otherwise be used.

When parsing, this chronology will be set on the parsed datetime.

A null chronology means no-override. If both an override chronology and an override zone are set, the override zone will take precedence over the zone in the chronology.
[中]返回一个新的格式化程序，该格式化程序将优先使用指定的时间顺序，而不是打印对象的时间顺序，或在解析时使用ISO。
打印时，此计时将优先于使用datetime的年表。
解析时，将在解析的日期时间上设置此年表。
空的时间顺序表示没有覆盖。如果同时设置了替代年表和替代分区，则替代分区将优先于年表中的分区。
