DiscoveryClient_EMPLOYEE-SERVICE / localhost：employee-service：9090-注册失败，无法在任何已知服务器上执行请求
我正在从此处运行代码：https://dzone.com/articles/quick-guide-to-microservices-with-spring-boot-20-e，并且仅更新了 spring boot 依赖版本 2.0.4.RELEASE ，其中代码运行得很好，但是当我更新Spring Boot版本 2.1.2.RELEASE 时，其中的代码给出了错误。
看来discovery-service并未从config-service中读取配置详细信息，因此这会产生以下错误。 spring.profiles.active=native是否有任何变化？似乎此配置设置无法正常运行。
