Enable STOMP

STOMP over WebSocket support is available in the spring-messaging and spring-websocket modules. Once you have those dependencies, you can expose a STOMP endpoint over WebSocket, as the following example shows:

import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

	@Override
	public void registerStompEndpoints(StompEndpointRegistry registry) {
		registry.addEndpoint("/portfolio"); (1)
	}

	@Override
	public void configureMessageBroker(MessageBrokerRegistry config) {
		config.setApplicationDestinationPrefixes("/app"); (2)
		config.enableSimpleBroker("/topic", "/queue"); (3)
	}
}
1 /portfolio is the HTTP URL for the endpoint to which a WebSocket (or SockJS) client needs to connect for the WebSocket handshake.
2 STOMP messages whose destination header begins with /app are routed to @MessageMapping methods in @Controller classes.
3 Use the built-in message broker for subscriptions and broadcasting and route messages whose destination header begins with /topic or /queue to the broker.

The following example shows the XML configuration equivalent of the preceding example:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:websocket="http://www.springframework.org/schema/websocket"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans
		https://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/websocket
		https://www.springframework.org/schema/websocket/spring-websocket.xsd">

	<websocket:message-broker application-destination-prefix="/app">
		<websocket:stomp-endpoint path="/portfolio" />
		<websocket:simple-broker prefix="/topic, /queue"/>
	</websocket:message-broker>

</beans>
For the built-in simple broker, the /topic and /queue prefixes do not have any special meaning. They are merely a convention to differentiate between pub-sub versus point-to-point messaging (that is, many subscribers versus one consumer). When you use an external broker, check the STOMP page of the broker to understand what kind of STOMP destinations and prefixes it supports.

To connect from a browser, for STOMP, you can use stomp-js/stompjs which is the most actively maintained JavaScript library.

The following example code is based on it:

const stompClient = new StompJs.Client({
       brokerURL: 'ws://domain.com/portfolio',
       onConnect: () => {
           // ...
       }
   });

Alternatively, if you connect through SockJS, you can enable the SockJS Fallback on server-side with registry.addEndpoint("/portfolio").withSockJS() and on JavaScript side, by following those instructions.

Note that stompClient in the preceding example does not need to specify login and passcode headers. Even if it did, they would be ignored (or, rather, overridden) on the server side. See Connecting to a Broker and Authentication for more information on authentication.
