类名称：ACL
方法名：impersonate

ACL.impersonate介绍

[英]Changes the Authentication associated with the current thread to the specified one, and returns the previous security context.

When the impersonation is over, be sure to restore the previous authentication via SecurityContextHolder.setContext(returnValueFromThisMethod); or just use #impersonate(Authentication,Runnable).

We need to create a new SecurityContext instead of SecurityContext#setAuthentication(Authentication)because the same SecurityContext object is reused for all the concurrent requests from the same session.
[中]将与当前线程关联的身份验证更改为指定的身份验证，并返回以前的安全上下文。
模拟结束后，请确保通过SecurityContextHolder恢复以前的身份验证。setContext（returnValueFromThisMethod）；或者只使用#模拟（身份验证，可运行）。
我们需要创建一个新的SecurityContext，而不是SecurityContext#setAuthentication（身份验证），因为同一个SecurityContext对象可用于来自同一会话的所有并发请求。
