In spring cloud, the default configuration for the Ribbon is as follows, in the following format: Beantype beanname:classname

1, Iclientconfig Ribbonclientconfig:defaultclientconfigimpl

2, IRule Ribbonping:zoneavoidancerule

3, IPing ribbonping:noopping

4, ServerList Ribbonserverlist:configurationbasedserverlist

5, Serverlistfilter Ribbonserverlistfilter:zonepreferenceserverlistfilter

6, Iloadbalancer Ribbonloadbalancer:zoneawareloadbalancer

Analyze the following code: (org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration)

@Bean @conditionalonmissingbeanpublic IRule ribbonrule (iclientconfig config) {zoneavoidancerule rule = new Zoneavoidanc  Erule ();  Rule.initwithniwsconfig (config); return rule;}
