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

解决

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

server:
  port: 9000
  servlet:
    context-path: /
spring:
  application:
    name: ym-base
  main:
    allow-bean-definition-overriding: true #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
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848 #nacos配置中心地址
        file-extension: yaml #文件扩展格式
        username: nacos
        password: nacos
  profiles:
    active: '@spring.active@' #对应nacos的Data ID命名规则
