【springcloud】springcloud Cannot execute request on any known server

在搭建springcloud eureka服务端和一个spring cloud config服务端 时 先启动了config服务器 在启动eureka服务器 

这时eureka启动报错，

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

通过排查 原因是自己yml文件写错了。

修改成bootstrap.yml 就可以了
