@Retention(value=RUNTIME) @Target(value=TYPE) @Documented @Import(value=DelegatingWebSocketConfiguration.class) public @interface EnableWebSocket
@Configuration class to configure
 processing WebSocket requests. A typical configuration would look like this:
 
 @Configuration
 @EnableWebSocket
 public class MyWebSocketConfig {
 }
 
 Customize the imported configuration by implementing the
 WebSocketConfigurer interface:
 
 @Configuration
 @EnableWebSocket
 public class MyConfiguration implements WebSocketConfigurer {
           @Override
           public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
         registry.addHandler(echoWebSocketHandler(), "/echo").withSockJS();
           }
           @Override
           public WebSocketHandler echoWebSocketHandler() {
         return new EchoWebSocketHandler();
     }
 }
