springcloud-3:required a bean of type 'com.netflix.discovery.DiscoveryClient' that could not be found.

在写客户端程序的时候，总是报'com.netflix.discovery.DiscoveryClient' that could not be found。

原因在于导入了错误的类：com.netflix.discovery.DiscoveryClient

应该是引用：org.springframework.cloud.client.discovery.DiscoveryClient
