Annotation Type EnableWebSocketMessageBroker

@Retention(value=RUNTIME)
 @Target(value=TYPE)
 @Documented
 @Import(value=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 the convenient base class AbstractWebSocketMessageBrokerConfigurer:

 @Configuration
 @EnableWebSocketMessageBroker
 public class MyConfiguration implements extends AbstractWebSocketMessageBrokerConfigurer {

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

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