java – com.netflix.discovery.shared.transport.TransportException：无法在任何已知服务器上执行请求

我是微服务的新手,并试图从链接： https://dzone.com/articles/advanced-microservices-security-with-spring-and-oa运行代码.当我只是运行代码时,我看到出现以下错误.

有什么问题？

我没有在系统上安装任何特殊功能.请告诉我我需要安装什么？

eureka.client.register-with-eureka=false

eureka.client.fetch-registry=false
