我有一个配置了tcp-ip的有效的Hazelcast群集。我需要它与Eureka发现一起使用。我正在尝试实现hazelcast-eureka-one插件。
（Spring-Boot）应用程序当前已经使用@EnableEurekaClient注释成功地向Eureka注册了自己。我不关心hazelcast eureka客户端是相同还是不同的客户端。我可以将hazelcast与应用分开注册。只要有效。
当我删除eureka-client.properties时，该应用程序将无法启动，并显示错误消息，找不到eureka-client.properties。将文件放置到位后，应用程序启动，但显然eureka-client.properties中的所有属性均未加载，这使hazelcast无法知道eureka服务器在哪里。日志表明已找到属性文件，但似乎未导入任何属性。
将hazelcast-eureka-one升级到1.1不会改变。
将用于主机和端口的元数据设置为true不会更改。

答案 0 :(得分：1)
您在namespace中的hazelcast.xml必须与eureka-client.properties中属性的前缀相同。
换句话说，您需要将命名空间更改为：
<property name="namespace">hazelcast</property>
或将您的eureka-client.properties更改为：
hazelcast-app-name.shouldUseDns=false
hazelcast-app-name.datacenter=primary
hazelcast-app-name.name=hazelcast-app-name-sessions
hazelcast-app-name.serviceUrl.default=http://username:password@svcregistry1-dev.company.com:8580/eureka/,http://username:password@svcregistry2-dev.company.com:8590/eureka/
