This periodic background refresh will be retried in 30 seconds. status = Cannot execute request on any known server stacktrace = com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
原因：
调用心跳函数向注册中心发送信息时解析失败
解決方案：
euraka要求服务端和客户端的后缀要为eureka保持一致
我的服务端配置
我的客户端配置
修改为：
服务端
客户端
启动成功。
