ThreadContext.getSecurityManager介绍

[英]Convenience method that simplifies retrieval of the application's SecurityManager instance from the current thread. If there is no SecurityManager bound to the thread (probably because framework code did not bind it to the thread), this method returns null.

It is merely a convenient wrapper for the following:

return (SecurityManager)get( SECURITY_MANAGER_KEY );

This method only returns the bound value if it exists - it does not remove it from the thread. To remove it, one must call #unbindSecurityManager() instead.
[中]简化从当前线程检索应用程序的SecurityManager实例的便捷方法。如果没有绑定到线程的SecurityManager（可能是因为框架代码没有将其绑定到线程），此方法将返回null。
它只是以下内容的方便包装：
return (SecurityManager)get( SECURITY_MANAGER_KEY );
此方法仅在绑定值存在时返回它——它不会将其从线程中移除。要删除它，必须调用#unbindSecurityManager（）。
