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

LocalDateTime.minusHours介绍

[英]Returns a copy of this LocalDateTime with the specified period in hours subtracted.

This instance is immutable and unaffected by this method call.
[中]返回此LocalDateTime的副本，并减去指定的时间段（以小时为单位）。
此实例是不可变的，不受此方法调用的影响。
