FileUtils.checkFileAccessWithImpersonation介绍

[英]Perform a check to determine if the user is able to access the file passed in. If the user name passed in is different from the current user, this method will attempt to do impersonate the user to do the check; the current user should be able to create proxy users in this case.
[中]执行检查以确定用户是否能够访问传入的文件。如果传入的用户名与当前用户不同，此方法将尝试模拟用户进行检查；在这种情况下，当前用户应该能够创建代理用户。
