Feign报错：The bean 'xxx.FeignClientSpecification' could not be registered.

Java 项目中Spring Cloud组件中Feign，使用异常，提示如下

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

解决方案

 可以在配置文件中，添加如下配置

spring:
  main:
    allow-bean-definition-overriding: true
