Java的。 在Linux中以root身份保存文件

Question

如何在具有root访问权限的文件夹中保存java应用程序生成的文件？

Answer 1

The straight forward way to do that is to run your application as the root user.

Another solution is to ask to the user the root password. To do that, you have to ask the "su" command of your system. Be careful, your user must have the "wheel" group. Or, you can use sudo (make sure that sudo is installed and configured for the current user).

As caarlos0 said in the comments, you can use "kdesu" or "gtksu/gksudo" if you prefer.

Of course, your application is not portable ! On windows, there's no "su", "sudo", etc.
