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

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException:
Invalid bean definition with name xxxx.FeignClientSpecification' defined in null:
Cannot register bean definition [Generic bean: class [org.springframework.cloud.openfeign.FeignClientSpecification]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] for bean 'xxxx.FeignClientSpecification': There is already [Generic bean: class [org.springframework.cloud.openfeign.FeignClientSpecification]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] bound.

解决方案

多个接口上的@FeignClient("相同服务名")会报错,A bean with that name has already been defined in null and overriding is disabled.

在application.yml中配置:

1

3
spring:
main:
allow-bean-definition-overriding: true
