How to use spring-messaging-5.1.* to connect stomp+ssl broker?

Question

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.

@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());
   }}

ReactorNettyTcpClient is the implementation of TcpOperations in spring-messaging-5.1.*, how can it support SSL?

Answer 1

Recently encountered this issue using ActiveMQ.

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {

    ReactorNettyTcpClient<byte[]> client = new ReactorNettyTcpClient<>(builder -> { 
        builder.port(activeMQProperties.getPort())
               .host(activeMQProperties.getHost())
               .sslSupport(opts -> { /* set SSL options here */})
    }, new StompReactorNettyCodec());

    registry.setApplicationDestinationPrefixes("/app");
    registry.enableStompBrokerRelay("/queue", "/topic")
        .setAutoStartup(true)
        .setVirtualHost(activeMQProperties.getHost())
        .setSystemLogin(activeMQProperties.getUser())
        .setSystemPasscode(activeMQProperties.getPassword())
        .setClientLogin(activeMQProperties.getUser())
        .setClientPasscode(activeMQProperties.getPassword())
        .setTcpClient(client);
}}

Works like a charm. One thing I needed to do was slightly update TCP client creation:

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {

    ReactorNettyTcpClient<byte[]> tcpClient = new ReactorNettyTcpClient<>(configurer -> configurer
            .host(properties.getRelayHost())
            .port(properties.getRelayPort())
            .secure(), new StompReactorNettyCodec());

    registry.enableStompBrokerRelay("/queue", "/topic")
            .setAutoStartup(true)
            .setSystemLogin(properties.getClientLogin())
            .setSystemPasscode(properties.getClientPasscode())
            .setClientLogin(properties.getClientLogin())
            .setClientPasscode(properties.getClientPasscode())
            .setTcpClient(tcpClient);

    registry.setApplicationDestinationPrefixes("/app");
    }
