Spring Cloud采坑记录

一、Caused by: java.lang.ClassNotFoundException: feign.Feign$Builder

原因：没有引用jar包

在pom文件引用jar

   org.springframework.cloud
   spring-cloud-starter-feign

二、使用fegin时，编写service调用服务接口，启动报错

出现以下错误：

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

Description:


Field demoFeignClient in org.crazyit.cloud.TestController required a bean of type 'org.crazyit.client.DemoFeignClient' that could not be found.




Action:


Consider defining a bean of type 'org.crazyit.client.DemoFeignClient' in your configuration.

Disconnected from the target VM, address: '127.0.0.1:10453', transport: 'socket'

错误原因：fegin调用所在包没有被扫描到，在项目启动时，注解添加扫描包
