请把提供你使用的软件版本号信息，以及问题的上下文（是运行ServiceComb Demo，还是你自己改写的程序），单从描述来看有可能是服务中心 ServiceCenter没有启动。

[wz510172336]

你的项目能跑，目前是想按照你的demo，集成到我的springboot项目中，你有配套完整的软件依赖包吗？按照你servicecomb-demo项目的父pom及子pom依赖，全按我的层级关系加到了我项目pom文件中，目前serviercenter及postgrasql、alpha、都已经启动，但是我的项目微服务模块就是注册不上服务，我引用包是你项目install的pack包，依赖是：

org.springframework.boot spring-boot-starter-actuator com.google.guava guava org.apache.commons commons-lang3 org.apache.servicecomb spring-boot-starter-provider org.hibernate hibernate-validator org.apache.servicecomb.pack omega-spring-starter org.apache.servicecomb.pack omega-transport-servicecomb org.apache.servicecomb.pack omega-connector-grpc

[WillemJiang]

这个错和之前的那个错不一样。 之前的错是和 ServiceComb 注册中心相关的，新的错是Alpha Server 连不上 Omega 实例。

@wz510172336 请问问题解决了吗？

[WillemJiang]

长期没有回复，先关闭问题了。
