Zuul网关启动报错：The bean 'proxyRequestHelper', defined in class path resource [org/springframework/cloud

背景：构建springcloud微服务过程中，通过Zuul的微服务网关，实现身份认证，动态路由，负载均衡等过滤需求。

问题：启动zuul服务时，报错，无法启动

Description:

The bean 'proxyRequestHelper', defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$NoActuatorConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$EndpointConfiguration.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

主要是springboot的版本与是springcloud的版本兼容出现问题，需要调整springboot，springcloud和zuul的版本

springboot：

    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.1.RELEASE
        
    

springcloud：

Greenwich.RC1

zuul依赖：

   org.springframework.cloud
   spring-cloud-starter-netflix-zuul
   2.2.0.RC1
