body: <p>I wanna using stomp over websocket and intend to integrate with Amazon MQ, but Amazon MQ using stomp+ssl as default, then i encounter my problem.</p>
  
  <pre><code>@Configuration
  @EnableWebSocketMessageBroker
  public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
  
  @Autowired
  private ActiveMQProperties activeMQProperties;
  
  /**
   * Register STOMP endpoints mapping each to a specific URL and (optionally)
   * enabling and configuring SockJS fallback options.
   *
   * @param registry
   */
  @Override
  public void registerStompEndpoints(StompEndpointRegistry registry) {
      registry.addEndpoint("/endpoint").setAllowedOrigins("*");
  }
  
  /**
   * Configure message broker options.
   *
   * @param registry
   */
  @Override
  public void configureMessageBroker(MessageBrokerRegistry registry) {
      registry.setApplicationDestinationPrefixes("/app");
      registry.enableStompBrokerRelay("/queue", "/topic")
              .setAutoStartup(true)
              .setVirtualHost(activeMQProperties.getHost())
              .setRelayHost(activeMQProperties.getHost())
              .setRelayPort(activeMQProperties.getPort())
              .setSystemLogin(activeMQProperties.getUser())
              .setSystemPasscode(activeMQProperties.getPassword())
              .setClientLogin(activeMQProperties.getUser())
              .setClientPasscode(activeMQProperties.getPassword());
     }}
