Hazelcast 需要作为现有集群中的客户端而不是成员进行连接

Question

我在服务器端所做的更改：

@Bean(name = {"hazelcast"})
public HazelcastInstance hazelcastInstance() {
ClientConfig clientConfig = new ClientConfig();
clientConfig.getGroupConfig().setName(integrationSettings.getHazelcastClusterGroupName())
.setPassword(integrationSettings.getHazelcastClusterGroupPass());
final ClientNetworkConfig clientNetworkConfig = new ClientNetworkConfig();
clientNetworkConfig.addAddress("127.0.0.1:6701");
clientConfig.setNetworkConfig(clientNetworkConfig);
clientConfig.setInstanceName("INTEGRATION_INSTANCE");
final String hazelcastEnterpriseLicenseKey = null;
if (hazelcastEnterpriseLicenseKey != null) {
clientConfig.setLicenseKey(hazelcastEnterpriseLicenseKey);
}
return HazelcastClient.newHazelcastClient(clientConfig);
}

我将从我的属性文件中获取我的组名和密码。

我的客户端代码：

ClientConfig clientConfig = new ClientConfig();            
clientConfig.getGroupConfig().setName(hazelcastGroupName).setPassword(hazelcastGroupPwd);
clientConfig.getNetworkConfig().addAddress(serverAddress);
hazelcastInstance = HazelcastClient.newHazelcastClient(clientConfig);

我的错误日志：

我需要将我的 hazelcast 作为客户端连接，但此 bean 异常使部署失败。还有其他方法吗？

查看您的代码，您正在服务器端和客户端创建"Hazelcast-Client"。 在服务器端代码中，请通过传递"Config"对象而不是"ClientConfig"来创建一个 hazelcast ServerMember 实例，更像

@Bean
public HazelcastInstance hazelcastInstance() throws Exception {
Config cfg = new Config();
...
...
HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);
return instance;
}

Hazelcast-client可以连接到Hazelcast ServerMember。您还需要确保在客户端可以连接到服务器成员之前启动它。
