Checking if periodic ScheduledFuture is running now

I have a periodic task scheduled via Spring TaskScheduler.schedule(Runnable, Trigger).

Given the returned ScheduledFuture, is there any way to check, if the task is running at current moment?


  • You can change you Runnable like this:

    class Runner implements Runnable{
        public volatile boolean RUNNING = false;
            public void run(){
            RUNNING = true;
                // Your code
            } finally {
                RUNNING = false;

    edit Thought operations with boolean are atomic and don't need to be volatile.
