How to get a process id of exe running through java program

问题

I am running a exe through java runtime api

     Process process = runTime.exec("cmd.exe /c start abc.exe "+Id, null, new       File("D:/My"));

and retrieving the process id using jna like this -

    Kernel32.INSTANCE.GetProcessId((Long) f.get(process));

but the process id return is not of abc.exe but of cmd.exe ..... i need the process id of abc.exe . Do not know how to get that can anyone help.

回答1:

The process is an object of type java.lang.Process. You can get the process id of abc.exe by using the Reflection API.

Field field = process.getClass().getDeclaredField("pid");
field.setAccessible(true);
System.out.println( field.get( process ) );

i cant get the process id of the exe start through cmd.exe but my purpose was served by making the cmd.exe to wait till the child exe is running using following command

Process process = runTime.exec("cmd.exe /c start /wait abc.exe "+Id, null, new       File("D:/My"));

and i got the process id of the cmd.exe using jna-api
