@Import(DelegatingWebSocketMessageBrokerConfiguration.class)
public @interface EnableWebSocketMessageBroker

Add this annotation to an @Configuration class to enable broker-backed messaging over WebSocket using a higher-level messaging sub-protocol.

 @Configuration
 @EnableWebSocketMessageBroker
 public class MyWebSocketConfig {

 }
 

Customize the imported configuration by implementing the WebSocketMessageBrokerConfigurer interface or more likely extend the convenient base class AbstractWebSocketMessageBrokerConfigurer:

 @Configuration
 @EnableWebSocketMessageBroker
 public class MyConfiguration extends AbstractWebSocketMessageBrokerConfigurer {

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

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