本文整理了Java中org.apache.shiro.subject.Subject.runAs()方法的一些代码示例，展示了Subject.runAs()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。Subject.runAs()方法的具体详情如下：
包路径：org.apache.shiro.subject.Subject
类名称：Subject
方法名：runAs

Subject.runAs介绍

[英]Allows this subject to 'run as' or 'assume' another identity indefinitely. This can only be called when the Subject instance already has an identity (i.e. they are remembered from a previous log-in or they have authenticated during their current session).

Some notes about runAs:

• You can tell if a Subject is 'running as' another identity by calling the #isRunAs() method.
• If running as another identity, you can determine what the previous 'pre run as' identity was by calling the #getPreviousPrincipals() method.
• When you want a Subject to stop running as another identity, you can return to its previous 'pre run as' identity by calling the #releaseRunAs() method.
  [中]允许此主题无限期地“运行为”或“假定”另一身份。只有当主题实例已经具有标识时（即，他们从以前的登录中被记住，或者他们在当前会话中进行了身份验证），才能调用此函数。
  关于runAs的一些注意事项：
  *通过调用#isRunAs（）方法，可以判断一个主题是否作为另一个身份“运行”。
  *如果以另一个身份运行，可以通过调用#GetPreviousPrinciples（）方法来确定上一个“pre run as”身份是什么。
  *当您希望主题停止以另一身份运行时，可以通过调用#releaseRunAs（）方法返回到其以前的“pre run as”身份。
