Websocket + ActiveMQ配置

Question

我尝试使用 ActiveMQ （消息代理）配置 Websocket 。

启动 Springboot 应用程序时，我收到以下消息：

8.12.20 10:57:44.705 [tcp-client-loop-nio-3] INFO  o.s.m.s.s.StompBrokerRelayMessageHandler - TCP connection failure in session _system_: Failed to connect: Connection timed out: no further information: /192.168.1.88:61613

    at java.lang.Thread.run(Thread.java:748)
Caused by: java.net.ConnectException: Connection timed out: no further information

这是 application.yml 中 ActiveMQ 的配置：

activemq:
      broker-url: vm://embedded?broker.persistent=false,useShutdownHook=false
      in-memory: true
      non-blocking-redelivery: true
      packages:
        trust-all: false
        trusted: com.memorynotfound
      pool:
        block-if-full: true
        block-if-full-timeout: -1
        enabled: false
        idle-timeout: 30000
        max-connections: 1
        max-sessions-per-connection: 500
        time-between-expiration-check: -1
        use-anonymous-producers: true

  # Spring JMS Settings
  jms:
    listener:
      acknowledge-mode: auto
      auto-startup: true
      concurrency: 5
      max-concurrency: 10
    pub-sub-domain: false
    template:
      default-destination:
      delivery-mode: NON_PERSISTENT
      priority: 100
      qos-enabled: true
      receive-timeout: 1000
      time-to-live: 36000

这是 Websocket 配置类：

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

  @Override
  public void configureMessageBroker(MessageBrokerRegistry config) {
    config.enableStompBrokerRelay("/topic").setRelayHost("192.168.1.88").setRelayPort(61613);

    config.setApplicationDestinationPrefixes("/app");
  }

  @Override
  public void registerStompEndpoints(StompEndpointRegistry registry) {
        ...
  }
}

我不知道relayHost和relayPort是否具有正确的值-我尝试了几对主机/端口，但没有成功（localhost，vm：// localhost，vm：// embedded等）

此错误（？）消息的性质是什么：ActiveMQ超时问题？ relayHost和relayPort的当前值正确吗？...

有什么想法吗？

感谢您的进阶。
