Question

我在hazelcast实例上有以下代码：

ITopic<String> topic;
HazelcastInstance hz = Hazelcast.newHazelcastInstance();
topic = hz.getTopic("data");

数据重复发布到主题

String event = "abc123"
topic.publish(event);

然后在局域网上的另一台机器上运行客户端，如下所示：

public class Listener implements MessageListener<String>
{
    ClientConfig clientConfig = new ClientConfig();     
    clientConfig.getNetworkConfig().addAddress("192.168.21.89:5701");
    HazelcastInstance client = HazelcastClient.newHazelcastClient(clientConfig);

    ITopic<String> topic = client.getTopic("data");
    topic.addMessageListener(new Listener());  

    public void onMessage(Message<String> m) {
        System.out.println("onMessage");
    }
}

客户端找到hz节点并启动，但在iTopic上看不到任何数据消息。我认为hz实例和客户端默认会自动发现对方？我是否必须以某种方式为网络配置hz？

客户端日志显示：

这是我自己的问题，因为我实际上并没有发布我想听的数据。 Aaargh！

hazelcast客户端iTopic没有看到这个话题
