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

LocalDateTime.plusMonths介绍

[英]Returns a copy of this LocalDateTime with the specified period in months added.

This method adds the specified amount to the months field in three steps:

  1. Add the input months to the month-of-year field
  2. Check if the resulting date would be invalid
  3. Adjust the day-of-month to the last valid day if necessary

For example, 2007-03-31 plus one month would result in the invalid date 2007-04-31. Instead of returning an invalid result, the last valid day of the month, 2007-04-30, is selected instead.

This instance is immutable and unaffected by this method call.
[中]返回此LocalDateTime的副本，并添加指定的期间（以月为单位）。
此方法分三步将指定金额添加到“月份”字段：
1.将输入月份添加到“年度月份”字段
1.检查结果日期是否无效
1.如有必要，将月份日期调整为最后一个有效日期
例如，2007-03-31加上一个月将导致无效日期2007-04-31。将选择月份的最后一个有效日期2007-04-30，而不是返回无效结果。
此实例是不可变的，不受此方法调用的影响。
