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

ACL.as介绍

[英]Changes the Authentication associated with the current thread to the specified one and returns an AutoCloseable that restores the previous security context.

This makes impersonation much easier within code as it can now be used using the try with resources construct:

try (ACLContext ctx = ACL.as(auth)) { 
... 
}

[中]将与当前线程关联的身份验证更改为指定的身份验证，并返回可自动关闭的身份验证，以恢复以前的安全上下文。
这使得代码中的模拟更加容易，因为现在可以使用try with resources构造来使用它：

try (ACLContext ctx = ACL.as(auth)) { 
... 
}
