The bean 'cyb-weixin.FeignClientSpecification' could not be registered. A bean with that name has already been defined and overriding is disabled.

该错误原因是springboot2.0以后，默认不允许同一个服务中接口中存在多个feign实体bean，即@FeignClient(“相同服务名”)会报错

解决办法：在bootstrap.yml文件中添加如下配置，注意该配置不能配置到配置中心

spring.main.allow-bean-definition-overriding=true
