"message:Broker not available." 在 spring websocket 上执行 stomp 时出错

Question

我正在使用 spring WebSocket、SockJs 和 Amazon MQ 构建示例聊天应用程序。当客户端订阅主题时，它会抛出 'broker not available' 异常。所有入站流量规则都在 AWS 安全组中正确设置，并且代理也有 stomp 支持。我正在关注这个 Spring Guide。

如果我使用内存代理，它工作正常。非常感谢您对此的帮助，以下是示例代码。

代理：Amazon MQ（内部使用 Active MQ）

版本：5.15.0

WebSocketConfig.java

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {

    registry.enableStompBrokerRelay("/topic")
            .setRelayHost("***********.mq.us-east-2.amazonaws.com").setRelayPort(61614)
            .setClientLogin("******").setClientPasscode("*****");

    registry.setApplicationDestinationPrefixes("/app");

}

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {

    registry.addEndpoint("/chat-endpoint").withSockJS();
}

客户端

var socket = new SockJS('/chat-endpoint');
    stompClient = Stomp.over(socket);

    stompClient.connect({}, function(frame) {

        setConnected(true);
        stompClient.subscribe('/topic/message', function(message) {
                                   displayMessage(message); });

});

我遇到了同样的问题。为了修复它，我稍微更改了 configureMessageBroker 方法：

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        ReactorNettyTcpClient<byte[]> client = new ReactorNettyTcpClient<>(tcpClient -> tcpClient
                .host("your-amazon-mq-host.amazonaws.com")
                .port(61614)
                .secure(SslProvider.defaultClientProvider()), new StompReactorNettyCodec());

        registry.setApplicationDestinationPrefixes("/app");
        registry.enableStompBrokerRelay("/queue", "/topic")
                .setAutoStartup(true)
                .setSystemLogin("amazonmq-login")
                .setSystemPasscode("amazonmq-pass")
                .setClientLogin("amazonmq-login")
                .setClientPasscode("amazonmq-pass")
                .setTcpClient(client);
    }
