Spring Boot Web Socket RabbitMQ 不可用

Question

我有带有网络套接字配置的简单 Spring Boot 应用程序。

当我使用SimpleBroker（由spring提供）运行我的应用程序时，一切正常，但是当我想使用rabbitmq而不是SimpleBroker时，我遇到了一些问题，我的经纪人“不可用”

@Configuration
@EnableWebSocketMessageBroker
open class WebSocketConfig : ILogging by LoggingImp<WebSocketConfig>(), 
WebSocketMessageBrokerConfigurer {

@Autowired
private lateinit var env: Environment

override fun registerStompEndpoints(registry: StompEndpointRegistry) {
    registry.addEndpoint("/hig").setAllowedOrigins("*").withSockJS()
}

override fun configureMessageBroker(registry: MessageBrokerRegistry) {
    registry.setApplicationDestinationPrefixes("/app")
    val host = env.getProperty("spring.rabbitmq.host")!!
    val port = env.getProperty("spring.rabbitmq.port")!!.toInt()
    val login = env.getProperty("spring.rabbitmq.username")!!
    val pass = env.getProperty("spring.rabbitmq.password")!!
    log.debug("webSocket=$host, $port, $login, $pass")
//        registry.enableSimpleBroker("/chat")
    registry.enableStompBrokerRelay("/chat")
            .setRelayHost(host)
            .setRelayPort(port)
            .setClientLogin(login)
            .setClientPasscode(pass)
            .setAutoStartup(true)
            .setSystemHeartbeatReceiveInterval(10000)
            .setSystemHeartbeatSendInterval(10000)
    }

}

来自 WebSocketMessageBrokerStats 的响应：

}

对于客户，我使用的是 Angular 5

当我使用时registry.enableSimpleBroker("/chat")一切正常

当我启用时registry.enableStompBrokerRelay("/chat")...我得到：

Answer 1

您正在尝试在不运行 stomp 适配器的rabbitmq 上使用 stomp 协议进行连接。跑步：

rabbitmq-plugins enable rabbitmq_stomp

启用踩踏。

此外，您正在连接到端口 5672，这是 amqp 协议/适配器。这就是为什么你有这个stompCommand=ERROR, nativeHeaders={message=[Broker not available.]}。启用后，stomp 适配器将默认侦听 tcp/61613。
