我在为现有Eureka客户端配置简单Hazelcast群集时遇到问题。我的应用程序是简单的Java SpringBoot应用程序，启用了Eureka发现，它可以正确地用于Eureka，但是Hazelcast集群不可用

这是我的配置：

@Bean
@Autowired
public HazelcastInstance hazelcastInstance( EurekaClient eurekaClient, GroupConfig groupConfig ) {

    EurekaOneDiscoveryStrategyFactory.setEurekaClient( eurekaClient );

    ClientConfig config = new ClientConfig();
    config.setGroupConfig( groupConfig );
    config.setProperty( "hazelcast.discovery.enabled", "true" );

    DiscoveryStrategyConfig discoveryStrategyConfig = new DiscoveryStrategyConfig( new EurekaOneDiscoveryStrategyFactory() );
    discoveryStrategyConfig.addProperty( "use-classpath-eureka-client-props", "false" );
    discoveryStrategyConfig.addProperty( "self-registration", "false" );

    DiscoveryConfig discoveryConfig = new DiscoveryConfig();
    discoveryConfig.addDiscoveryStrategyConfig( discoveryStrategyConfig );
    config.getNetworkConfig().setDiscoveryConfig( discoveryConfig );

    return HazelcastClient.newHazelcastClient( config );
}

配置类：

@Configuration
public class HazelcastInstanceConfiguration {

    @Bean
    public HazelcastInstance hazelcastInstance(Config config, EurekaClient eurekaClient) { 
        EurekaOneDiscoveryStrategyFactory.setEurekaClient( eurekaClient );
        return Hazelcast.newHazelcastInstance(config);
    }

    @Bean
    public Config config() {    
        Config config = new ClasspathXmlConfig( "hazelcast.xml" );
        return config;
    }
}

bootstrap.yml

然后我的缓存服务器应用程序可以在Eureka上使用，但我想hazelcast集群不应该这样

Hazelcast客户端服务日志（剪切）：

我的配置有什么问题，这是服务器问题还是客户端问题

客户端配置：

@Bean
@Autowired
public HazelcastInstance hazelcastInstance( EurekaClient eurekaClient, GroupConfig groupConfig ) {

    EurekaOneDiscoveryStrategyFactory.setEurekaClient( eurekaClient );

    ClientConfig config = new ClientConfig();
    config.setGroupConfig( groupConfig );
    config.setProperty( "hazelcast.discovery.enabled", "true" );

    DiscoveryStrategyConfig discoveryStrategyConfig = new DiscoveryStrategyConfig( new EurekaOneDiscoveryStrategyFactory() );
    discoveryStrategyConfig.addProperty( "use-classpath-eureka-client-props", "false" );
    discoveryStrategyConfig.addProperty( "self-registration", "false" );

    DiscoveryConfig discoveryConfig = new DiscoveryConfig();
    discoveryConfig.addDiscoveryStrategyConfig( discoveryStrategyConfig );
    config.getNetworkConfig().setDiscoveryConfig( discoveryConfig );

    return HazelcastClient.newHazelcastClient( config );
}

您是否看到了中的示例配置以及？我看你的配置和你的有些不同。如果您仍然有问题，请检查并告知我。

问题在于您使用相同的EurekaClient进行应用程序发现（端口7990）和Hazelcast发现（端口5701）。有关更多信息，请阅读相关的

您可以通过两种方式解决此问题：

如前所述，为主机和端口使用属性
```
使用元数据
```


为您的应用程序和Hazelcast使用单独的Eureka客户端和端口


编辑：主机和端口的使用元数据
将很快在hazelcast eureka:1.0.3
中发布。我也准备好了。

是的，我试着遵循它，但是缺少重用现有EurekaClient对象的示例。公平地说，我不知道我应该期望做什么hazelcast服务器注册，它应该像普通的Spring Boot应用程序一样在Eureka上可用吗？第二个链接有一个有点过于复杂的解决方案，因为它使用分区组，我只需要一个集群实例。是的，我试图遵循它，但是缺少重用现有EurekaClient对象的示例。公平地说，我不知道我应该期望做什么hazelcast服务器注册，它应该像普通的Spring Boot应用程序一样在Eureka上可用吗？第二个链接有一个过于复杂的解决方案，因为它使用分区组，我只需要一个集群实例。我认为这有助于我理解这个问题，我在Eureka成功注册了Hazelcast集群。现在的问题是，我无法从Eureka客户端应用程序（使用现有的、自动连接的EurekaClient）访问该集群。你能帮帮我吗？我用HazelcastInstance配置为客户端项目更新了帖子描述，正确注入了groupConfig。Hazelcast客户端尝试连接到本地端口，而不是eureka:hz.client_0[xxxx][3.11]尝试连接到[127.0.0.1]：5702作为所有者成员我认为在客户端中，您还需要指定名称空间
（将其设置为Hazelcast
）。我已经编辑了我的答案，请查看。另外，我还添加了代码示例，它将阐明如何使用Hazelcast Eureka插件。@RafałLeszko谢谢，添加了use metadata for host and port帮助我使用PCF register Service在PCF上注册Hazelcast成员。我认为这有助于我理解这个问题，我在Eureka成功注册了Hazelcast集群。现在的问题是，我无法从Eureka客户端应用程序（使用现有的、自动连接的EurekaClient）访问该集群。你能帮帮我吗？我用HazelcastInstance配置为客户端项目更新了帖子描述，正确注入了groupConfig。Hazelcast客户端尝试连接到本地端口，而不是eureka:hz.client_0[xxxx][3.11]尝试连接到[127.0.0.1]：5702作为所有者成员我认为在客户端中，您还需要指定名称空间
