在没有Windows任务计划程序的情况下计划可执行文件

Question

Is it possible to schedule a executable file to run just before log-off using java? I am working on a application that needed to send a message to the sever just before the system log-off/shutdown. But I didn't find any method to solve it. If anyone know plz help me.

Thanks in advnce.

Answer 1

As stated in the comments a ShutdownHook is probably what you are searching for. Short example:

Runtime.getRuntime().addShutdownHook(new Thread() {
  @Override 
  public void run() {
    // Code to be executed when JVM exits
    System.out.println("JVM exit");
  }
});

Note that the ShutdownHook will execute whenever the JVM exits. So it will also execute when your program terminates normally.
