I would advise against using STOMP as it requires a framework to be embedded in your code. Frameworks come and go, and need to be updated.

You can use a Spring (boot) WebSocket channel to pass JSON without ever using STOMP. If you are talking with a front end application (e.g. JavaScript) the JSON is already your "model" data that can easily be passed/parsed bidirectionally.

The WebSocket API contains enough to be able to onConnect(), onMessage(), onError() your implementation. Actually I prefer this, because I am in control. For instance in the onConnect, you can validate tokens and customize security.

This guide is using the simple broker implementation provided in Spring Framework. It's just a piece of Java code that plays that part - there's no actual broker in that setup. So yes, there is a broker-less way to use this, and you're already doing it.

This implementation lacks many features though, and you may want to use a real broker (like RabbitMQ) in production.

Edit:

You don't have to use STOMP and a message broker, in fact you can use the Websocket API directly. As stated in this presentation:

Using a WebSocket API directly is a bit like writing a custom Servlet application, except the WebSocket protocol is on lower level than HTTP.

Depending on your app goals, you may go towards a message-driven application anyway; not an easy task to solve on your own...
