已采纳

找到原因了，报Caused by: java.lang.ClassNotFoundException: org.springframework.cloud.client.loadbalancer.LoadBalancedRetryFactory，是依赖的版本不对，改成

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-feign</artifactId>
  <version>2.0.0.M1</version>
</dependency>

就OK了

用此版本依赖是可以的

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-feign</artifactId>
  <version>1.3.2.RELEASE</version>
</dependency>

我的也报这个错，引入spring-cloud-starter-feign后启动，会报以下错误，没有查到解决办法，feign这块没法用，类确实有，就是说找不到
