Disconnect client session from Spring websocket stomp server

Actually using some workarounds you can achieve what you want.
For that you should do:

1. Use java configuration (not sure if it is possible with XML config)
2. Extend your config class from WebSocketMessageBrokerConfigurationSupport and implement WebSocketMessageBrokerConfigurer interface
3. Create custom sub-protocol websocket handler and extend it from SubProtocolWebSocketHandler class
4. In your custom sub-protocol websocket handler override afterConnectionEstablished method and you will have access to WebSocketSession 🙂

I’ve created sample spring-boot project to show how we can disconnect client session from server side:
