我正在尝试将服务实例注册到发现服务器并收到以下错误

问题描述 投票：0回答：1

我尝试向在 docker 上运行的 eureka 发现服务器注册我的微服务实例。该应用程序运行良好，但是当我尝试注册一个实例时，它会注册它，但会带来这个运行时异常...这是我的错误日志...我很困惑，因为它试图连接到 localhost:8761我没有在配置文件中配置。

您是否尝试过将 

defaultZone
添加到 
eureka.client
配置中？我的意思是这样的：

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://localhost:8761/eureka
  instance:
    hostname: localhost
