Java Process Termination - onEnd()?

When you force kill a process by PID:

kill -9 1123

Is there any method that is called when the process is terminated, that halts until shutdown?

Solution

  • For java, you can add a ShutdownHook to your process, when sigterm is send to this process, the code in ShutdownHook will be executed before jvm shuts itself down.

        Runtime.getRuntime().addShutdownHook(new Thread() {
        @Override
        public void run() {
            //your cleanup codes
        }
    });
