ribbon

作为初始化@bean参数数

LoadBalancerContext.reconstructURIWithServer()

InterceptingClientHttpRequest.execute()

clientFactory.getLoadBalancer(serviceId)

restOfInit

DynamicServerListLoadBalancer

super()初始化父类

SmartInitializingSingleton

初始化

一般某个类初始化的地方可以直接去找项目下对应的configuration类里面找

this.iterator.hasNext()=false

@Bean

替换uri

LoadBalancerAutoConfiguration

设置server的定时平任务PingTask()

RibbonAutoConfiguration

RibbonLoadBalancerClient.execute()

 restTemplate.getForEntity(\"http://product-center/selectProductInfoById

ZoneAwareLoadBalancer

2.获取所以Nacoss实例列表

@AutoConfigureBefore

SpringClientFactory

RibbonClientConfiguration

用RestTemplateCustomizer定制所有的RestTemplate

@Bean初始化SpringClientFactory

ILoadBalancer

ILoadBalancer loadBalancer = getLoadBalancer(serviceId)

setPingInterval(pingIntervalTime)

初始化父类

RestTemplateCustomizer

updateListOfServers()

BaseLoadBalancer

定制restTemplate（将LLoadBalancerInterceptor封装到restTemplatede的拦截器集合里去）

PollingServerListUpdater

NacosServerList.getUpdatedListOfServers

LoadBalancerInterceptor

LoadBalancerInterceptor.intercept()

作为初始化@bean参数

实现

hostReactor.getServiceInfo

NamedContextFactory

将服务实例列表设置到父类的BaseLoadBalancer的allServerList

setServersList(ls)

返回实例列表

super.setServersList(lsrv)

updateAllServerList(servers)

IPing

LoadBalancerClient

enableAndInitLearnNewServersFeature()

1.ribbon定时获取nacos实例列表

作为bean 的初始化参数

ServiceRequestWrapper.getUrI()

request.apply(serviceInstance)

RibbonLoadBalancerClient

this.defaultConfigType = RibbonClientConfiguration;

1.获取负载均衡器

request.getURI()

serverListUpdater.start(updateAction)

从容器中获取loadBalancer

2.负载均衡器loadBalancer根据负载均衡算法获取服务

serverListImpl.getUpdatedListOfServers()

delegate.execute()

DynamicServerListLoadBalancer初始化实现了doUpdate方法

RibbonLoadBalancerClient.reconstructURI()

initWithConfig

restTemplate

被@LoadBalance注解的RestTemplates
