问题现象：
启动测试类（含通过Feign远程调用的组件），报错： No qualifying bean of type 'org.springframework.cloud.openfeign.FeignContext' available
问题解决：
在测试类上加上如下代码：
import org.springframework.cloud.netflix.ribbon.RibbonAutoConfiguration;
import org.springframework.cloud.openfeign.FeignAutoConfiguration;
import org.springframework.cloud.openfeign.ribbon.FeignRibbonClientAutoConfiguration;
@ImportAutoConfiguration({RibbonAutoConfiguration.class, FeignRibbonClientAutoConfiguration.class, FeignAutoConfiguration.class})
