How does ribbon get the default zoneawareloadbalancer?

1.ILoadBalancer family

2.ZoneAwareLoadBalancer Where was it declared ？

From the previous articles, I can see the default LoadBalancer yes ZoneAwareLoadBalancer, Where did it state ？
stay org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration in

as for RibbonClientConfiguration How to load is detailed , stay Ribbon Automatic injection , There is an initialization SpringClientFactory .

3. have a look ZoneAwareLoadBalancer What is needed for the creation of ？

@Bean
	@ConditionalOnMissingBean
	public ILoadBalancer ribbonLoadBalancer(
			IClientConfig config, //  Client configuration 
			ServerList<Server> serverList, //  List of services 
			ServerListFilter<Server> serverListFilter, //  Service filter 
			IRule rule,  //  Service selection rules 
			IPing ping,  //  Service detection tools 
			ServerListUpdater serverListUpdater //  Service regular update tool 
		) {
    
		if (this.propertiesFactory.isSet(ILoadBalancer.class, name)) {
    
			return this.propertiesFactory.get(ILoadBalancer.class, config, name);
		}
		return new ZoneAwareLoadBalancer<>(config, rule, ping, serverList,
				serverListFilter, serverListUpdater);
	}

What you need ：

• IClientConfig config, // Client configuration
• ServerList serverList, // List of services
• ServerListFilter serverListFilter, // Service filter
• IRule rule, // Service selection strategy
• IPing ping, // Service detection tools
• ServerListUpdater serverListUpdater // Service regular update tool

Where did these objects come from ？ It's all in RibbonClientConfiguration Declarative . It also represents ribbon Default configuration






In these classes , except RibbonLoadBalancerClient No other , Other core classes are here .ZoneAwareLoadBalancer How to get , And creating the required objects can basically be done in RibbonClientConfiguration in . Of course , Everything here is default ,ConditionalOnMissingBean This annotation is to tell spring, If other places have creation related bean, There is no longer initialization .
