The bean ‘xxx.FeignClientSpecification‘, defined in null, could not be registered. A bean with that

Spring Cloud + Nacos + OpenFeign

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


Process finished with exit code 1

Spring在启动扫描时检测到同名的FeignClient，导致初始化失败。

网上大多数教程都是说打开allow-bean-definition-overriding: true，但是尼玛我复写之后，生效的bean不就只有一个了，真是误人子弟，正确办法是在@FeignClient里面再多添加一个专属的contextId。
