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

DateTime.plusHours介绍

[英]Returns a copy of this datetime plus the specified number of hours.

The calculation will add a duration equivalent to the number of hours expressed in milliseconds.

For example, if a spring daylight savings cutover is from 01:59 to 03:00 then adding one hour to 01:30 will result in 03:30. This is a duration of one hour later, even though the hour field value changed from 1 to 3.

The following three lines are identical in effect:

DateTime added = dt.plusHours(6); 
DateTime added = dt.plus(Period.hours(6)); 
DateTime added = dt.withFieldAdded(DurationFieldType.hours(), 6);

This datetime instance is immutable and unaffected by this method call.
[中]返回此datetime加上指定小时数的副本。
该计算将添加一个与以毫秒表示的小时数相等的持续时间。
例如，如果春季夏令时切换时间为01:59到03:00，则将1小时添加到01:30将导致03:30。这是一个一小时后的持续时间，即使小时字段值从1更改为3。
以下三行实际上是相同的：

DateTime added = dt.plusHours(6); 
DateTime added = dt.plus(Period.hours(6)); 
DateTime added = dt.withFieldAdded(DurationFieldType.hours(), 6);

此datetime实例是不可变的，不受此方法调用的影响。
