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

AccessController.getContext介绍

[英]This method takes a "snapshot" of the current calling context, which includes the current Thread's inherited AccessControlContext, and places it in an AccessControlContext object. This context may then be checked at a later point, possibly in another thread.
[中]此方法获取当前调用上下文的“快照”，其中包括当前线程继承的AccessControlContext，并将其放置在AccessControlContext对象中。然后可能会在稍后的某个点（可能是在另一个线程中）检查此上下文。
