錯誤信息如下：
***************************
APPLICATION FAILED TO START
***************************
Description:
The bean 'xxx.FeignClientSpecification', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
錯誤里面已經提示出來了 ，主要是springboot2.x版本以后被@FeignClient標記的接口對應的服務名稱不能重復，原則上同一個服務的接口聲明都應該盡量放到一個里面
這里可以設置spring.main.allow-bean-definition-overriding=true來屏蔽此問題
