Question

我有两台不同的机器。一个配置为IP 192.168.2.100，另一个配置为192.168.2.101。这是第一个Verticle的代码：

 public class Sender extends AbstractVerticle {

public static void main(String... args) {

        // Configuration du cluster manager
        Config config = new Config();
        config.getNetworkConfig().getJoin().getTcpIpConfig().addMember("192.168.2.101");

        VertxOptions options = new VertxOptions();
        options.setClusterManager(new HazelcastClusterManager());
        options.setClusterHost("192.168.2.100");
        options.setClustered(true);
        options.setHAEnabled(true);


        Vertx.clusteredVertx(options, vertx ->
                vertx.result().deployVerticle(Sender.class.getName(), new DeploymentOptions().setHa(true))
        );
    }


    @Override
    public void start() throws Exception {

        vertx.setPeriodic(5000, id -> {
            vertx.eventBus().send("Address", "message",rep->{
            System.out.println("response : "+rep.result().body());
            });
        });
    }
}

这是第二个Verticle的代码：

 package com.vetx.Consumer;
import com.hazelcast.config.Config;



public class Consumer extends AbstractVerticle {

    private String name = null;

    public Consumer(String name) {
        this.name = name;
    }
    public Consumer(){

    }

    public static void main(String... args) {

        // Configuration du cluster manager
        Config config = new Config();
        config.getNetworkConfig().getJoin().getTcpIpConfig().addMember("192.168.2.100");

        VertxOptions options = new VertxOptions();
        options.setClusterManager(new HazelcastClusterManager());
        options.setClusterHost("192.168.2.101");
        options.setClustered(true);
        options.setHAEnabled(true);



        Vertx.clusteredVertx(options, vertx ->
                vertx.result().deployVerticle(Consumer.class.getName(), new DeploymentOptions().setHa(true))
        );
    }


    @Override
    public void start() throws Exception {

        vertx.eventBus().consumer("Address", message -> {
            System.out.println(" received message: " +message.body());
           message.reply("Success");
        });
    }
}

我尝试使用群集的高可用性来实现消费者使用消息和发送者发送消息。当尝试杀死发送者以便在故障转移后重新部署Verticle时，我得到以下异常：< / p>

两个集群成员都应在其类路径中具有类com.vetx.Sender.Sender，因为它将在两端进行序列化/反序列化。似乎其中一个成员没有它。另外，你确定成员可以形成一个2的集群吗？我看到你的网络配置在每个主机getTcpIpConfig().addMember("192.168.2.101")上都有一个ip，最佳做法是在所有主机上添加所有ip，即在所有主机上使用相同的网络配置以避免混淆。

具有高可用性的两台不同机器的集群？
