Spring websocket send message from async method

Question

I am using spring websocket 4.2.4 with sockjs and stomp and i am trying to send a message from the server to all the subscribers in an async task with no luck

my class is:

public class MyClass{
    private timer;
    public MyClass(){
        this.timer = new Timer();
    }

    @Async
    public void myMethod(){
        timer.schedule(new MyReminder(), 1000);
    }

    @Async
    private class MyReminder extends TimerTask{

        @Autowired
        SimpMessagingTemplate messageingTemplate;

        @Override
        public void run(){
            messageingTemplate.convertAndSend("/app/subscribers","message");
        }
    }
}

but the subscribers dont get the message

any help? what did i do wrong :(

* EDIT *

my message broker:

public void configureMessageBroker(MessageBrokerRegistry config){ 
    config.enableSimpleBroker("/topic","/myApp"); 
    config.setApplicationDestinationPrefixes("/myApp");
}

and when i subscribe:

subscribe("myApp/someRoute") 

thanks!!

** Edit 2: **

thanks for the help i fix the problem :)

Answer 1

You can do that but over Broker destination.

Share, please, your AbstractWebSocketMessageBrokerConfigurer .

Typically we do this:

public void configureMessageBroker(MessageBrokerRegistry registry) {
    registry.setApplicationDestinationPrefixes("/app/")
            .enableSimpleBroker("/queue/", "/topic/");
}

Where all those /app/ destinations won't be treated by Broker. You can subscribe to them only in case of @SubscribeMapping - the request-reply scenario from the client initiative.

Your task is fully fits to the publish-subscribe story - topic in terms of STOMP.

There fore your subscribers (clients) should be subscribed to some topic on the broker and after that you can simply send message to it.
