如何使用管理员权限从Java运行批处理文件？

Question

how to run a batch file from java using administrator privileges?

I am trying to do this.But code is not working.

String cmd = "runas /profile /user:Administrator /cmd.exe /C certutil -addstore ROOT  E:\\WORK\\UI\\DesktopRecorder\\userdata\\certgen\\X509CA\\ca\\new_ca.crt";

Runtime run = Runtime.getRuntime();
Process process = run.exec(cmd);

Answer 1

You can create a shortcut to your bat file and make it run as administrator from Properties > Advanced,

Now that you created a shortcut to your bat file lets say its name is example.bat and its located on C drive, so it means that its full name is c:\\\\example.bat.lnk

In order to run this shortcut, you will need to run it using ProcessBuilder, it should look like that:

ProcessBuilder pb = new ProcessBuilder("cmd", "/c","c:\\example.bat.lnk");   
Process p = pb.start();

It won't work using Runtime.getRuntime().exec();

runas needs its main input parameter encapsulated in double quotes. The kicker is that cmd.exe does too , if you are passing it a command string with spaces, so you will have to use escape characters for it to work on the windows command prompt:

runas /profile /user:Administrator "cmd.exe /C \"certutil -addstore ROOT  E:\\WORK\\UI\\DesktopRecorder\\userdata\\certgen\\X509CA\\ca\\new_ca.crt\""

You would then have to escape that entire string again for it to work in your java code:

String cmd = "runas /profile /user:Administrator \"cmd.exe /C \\\"certutil -addstore ROOT  E:\\\\WORK\\\\UI\\\\DesktopRecorder\\\\userdata\\\\certgen\\\\X509CA\\\\ca\\\\new_ca.crt\\\"\"";

Sometimes in runas with a nested cmd call, you don't have to escape the backslash \\ characters, so if that fails, you may want to try replacing the sequences of four backslashes with two. Good luck!
