How to stop all running threads in ThreadPoolTaskExecutor?

Question

I am add new threads like this using ThreadPoolTaskExecutor :

threadPoolTaskExecutor.execute(new Runnable() {

    @Override
    public void run() {
        while(true){
            doSomething();
        }

        Thread.sleep(1000); 
    }

});

All active threads are not stopped, when I shutdown this executor:

threadPoolTaskExecutor.shutdown();

Is there option how to stop this active threads using ThreadPoolTaskExecutor?

Answer 1

You should set setWaitForTasksToCompleteOnShutdown(false) when create ThreadPoolTaskExecutor.

Default is false, shutting down immediately through interrupting ongoing tasks and clearing the queue.
