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

DateTime.plusMonths介绍

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

The calculation will do its best to only change the month field retaining the same day of month. However, in certain circumstances, it may be necessary to alter smaller fields. For example, 2007-03-31 plus one month cannot result in 2007-04-31, so the day of month is adjusted to 2007-04-30.

The following three lines are identical in effect:

DateTime added = dt.plusMonths(6); 
DateTime added = dt.plus(Period.months(6)); 
DateTime added = dt.withFieldAdded(DurationFieldType.months(), 6);

This datetime instance is immutable and unaffected by this method call.
[中]返回此datetime加上指定月数的副本。
计算将尽最大努力只更改保留当月同一天的月份字段。但是，在某些情况下，可能需要更改较小的字段。例如，2007-03-31加上一个月不能生成2007-04-31，因此将月日调整为2007-04-30。
以下三行实际上是相同的：

DateTime added = dt.plusMonths(6); 
DateTime added = dt.plus(Period.months(6)); 
DateTime added = dt.withFieldAdded(DurationFieldType.months(), 6);

此datetime实例是不可变的，不受此方法调用的影响。
