I am try to implement a basic web socket app by following this tutorial:https://spring.io/guides/gs/messaging-stomp-websocket/

However, in that tutorial there was a client UI implementation. I don't want to use UI. Instead of the UI, I want to use a websocket client extension in Chrome for sending and seeing messages.

All codes same with the tutorial(except the UI part since I'dont want UI), so I don't rewrite all codes here.

I am able to connect and send message to the url: ws://localhost:8081/gs-guide-websocket for example,

enter image description here

However, I can't get response with this url: ws://localhost:8081/topic/greetings. (I use this URL for getting responses by subscribing it. Because this topic/greetings path used in the UI side of that tutorial for subscription) enter image description here

The Chrome extension that I used is Simple WebSocket Client.

Why I couldn't subscribe the ws://localhost:8081/topic/greetings url? and How can I get messages from the server by using the Chrome client websocket extensions?

Your application works with STOMP and SockJs, this plugin does not support that. It only works with ws. In this example, you can write a simple ws endpoint for your application: example simple ws endpoint
