### 问题 ###

报错如下：

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

    Description:
    
    The bean 'service-demo.FeignClientSpecification' could not be registered. A bean with that name has already been defined and overriding is disabled.
    
    Action:
    
    Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

### 解决 ###

1.  feign扫包
2.  rpc调用类中添加`contextId`值
3.  如果还不行，将该远程调用服务下的所有rpc相关类都添加`contextId`值，自己慢慢玩吧，小问题`^_^`

@FeignClient(value = "test",
            path = "/rpc/api/common",
            fallback = CommonFeignFallback.class,
            contextId = "CommonFeignApi")
    public interface CommonFeignApi { 
    
        @GetMapping("/getData")
        Boolean getData();
    
    }
