The bean 'xxx-xxx.FeignClientSpe

启动springboot项目，控制台报如下错误：
Description:
The bean 'xxx-xxx.FeignClientSpecification', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.

解决办法：
此错误是因为spring容器中存在相同名称的bean对象，在yml配置文件中配置代码
main:
allow-bean-definition-overriding: true
覆盖相同名称的bean即可：

spring:
  application:
    name: xxx-xxx-service
  main:
    allow-bean-definition-overriding: true  # 后来发现的bean会覆盖之前相同名称的bean
