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

|---|---|
| Greenwich |
2.1.x |
| Finchley |
2.0.x |
| Edgware |
1.5.x |
| Dalston |
1.5.x |
Greenwich构建SpringBoot2.1.x。
Finchley构建SpringBoot2.0.x并与其协同工作，而不是使用SpringBoot1.5.x。
Dalston和Edgware发布的列车构建在SpringBoot1.5.x。
Camden发布列车构建在SpringBoot1.4.x上。
