如何在Vertex Hazelcast群集中设置分布式事件总线？

这是发信人的头像 我已启用多播并将公用主机设置为我的计算机ip地址

VertxOptions options = new VertxOptions()
                .setClusterManager(ClusterManagerConfig.getClusterManager());
       EventBusOptions eventBusOptions = new EventBusOptions()
               .setClustered(true)
               .setClusterPublicHost("10.10.1.160");

        options.setEventBusOptions(eventBusOptions);



        Vertx.clusteredVertx(options, res -> {
            if (res.succeeded()) {
                Vertx vertx = res.result();
                vertx.deployVerticle(new requestHandler());
                vertx.deployVerticle(new requestSender());
             
                EventBus eventBus = vertx.eventBus();
                eventBus.send("some.address","hello",reply -> {
                    System.out.println(reply.toString());
                   
                });


            } else {
                LOGGER.info("Failed: " + res.cause());
            }
        });
    }

这是接收器的垂直方向

VertxOptions options = new VertxOptions().setClusterManager(mgr);
        options.setEventBusOptions(new EventBusOptions()
                .setClustered(true)
                .setClusterPublicHost("10.10.1.174") );



        Vertx.clusteredVertx(options, res -> {
            if (res.succeeded()) {
                Vertx vertx1 = res.result();

                System.out.println("Success");
                EventBus eb = vertx1.eventBus();
                System.out.println("ready");
                eb.consumer("some.address", message -> {
                  
                    message.reply("hello hello");
                });
            } else {
                System.out.println("Failed");
            }
        });

当我运行两个主垂直轴时，我得到了这个结果，因此hazelcast会检测到垂直轴并建立连接

但是当事件总线试图向给定地址发送消息时，我遇到了这个错误，这是事件总线配置的问题吗

在Vert.x 3中，集群主机和集群公共主机默认为

localhost

如果您仅在

VertxOptions

中更改群集公用主机，则Vert.x会将EventBus传输服务器绑定到

localhost

，同时通知其他节点连接到公用主机

在某些云提供商上运行Vert.x时需要这种配置，但在大多数情况下，您只需要设置集群主机（然后公共主机将默认为其值）：

EventBusOptions eventBusOptions = new EventBusOptions()
  .setClustered(true)
  .setHost("10.10.1.160");
