eureka-server-client启动流程

EurekaHttpClients#canonicalClientFactory

AbstractInstanceRegistry#register

<dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId></dependency>在这个依赖中有一个eureka客户端的依赖的jar包：<dependency>             <groupId>org.springframework.cloud</groupId>             <artifactId>spring-cloud-netflix-eureka-client</artifactId></dependency>进入jar保重查看到有对应的如下的结构：cloud/spring-cloud-netflix-eureka-client/2.1.2.RELEASE/spring-cloud-netflix-eureka-client-2.1.2.RELEASE.jar!/META-INF/spring.factories进入到spring.factories发现eureka客户端的自动配置

EurekaServerInitializerConfiguration#start

EurekaClientAutoConfiguration.RefreshableEurekaClientConfiguration#eurekaClient

AbstractJerseyEurekaHttpClient#getApplicationsInternal

RemoteRegionRegistry#fetchRemoteRegistry

DefaultEurekaServerContext

RefreshablePeerEurekaNodes

AbstractInstanceRegistry#initializedResponseCache

PeerAwareInstanceRegistryImpl#updateRenewalThreshold

服务续约

获得服务注册列表

AbstractInstanceRegistry#updateRenewsPerMinThreshold

RetryableEurekaHttpClient

EurekaClientAutoConfiguration#eurekaAutoServiceRegistration

SessionedEurekaHttpClient

EurekaServerMarkerConfiguration

RedirectingEurekaHttpClient

EurekaServerBootstrap

DiscoveryClient#register

DefaultEurekaServerContext#initialize

DiscoveryClient#initScheduledTasks

ResponseCacheImpl

AbstractJerseyEurekaHttpClient

往容器中添加了一个maker的bean

EurekaHttpClientDecorator#execute

EurekaClientAutoConfiguration.RefreshableEurekaClientConfiguration#eurekaApplicationInfoManager

InstanceRegistry#openForTraffic

PeerEurekaNodes#start

RemoteRegionRegistry#fetchRegistry

InstanceRegistry

@ConditionalOnBean({Marker.class})

DiscoveryClient#scheduleServerEndpointTask

RemoteRegionRegistry#fetchAndStoreDelta

EurekaServerBootstrap#contextInitialized

HeartbeatThread

ResponseCacheImpl#getCacheUpdateTask

DiscoveryClient#refreshInstanceInfo

EurekaServerHttpClients#createRemoteRegionClient

EurekaHttpClients#queryClientFactory

InstanceInfoReplicator#start

CacheRefreshThread

EurekaClientAutoConfiguration

AbstractInstanceRegistry#evict(long)

EnableEurekaServer（开启eureka服务端）

AbstractInstanceRegistry.EvictionTask#run

EurekaClientAutoConfiguration.RefreshableEurekaClientConfiguration#eurekaRegistration

MetricsCollectingEurekaHttpClient

JerseyEurekaHttpClientFactory

维护了服务注册列表

@Configuration@Import(EurekaServerInitializerConfiguration.class)EurekaServerAutoConfiguration（去掉部分东西，只保留关键内容）

PeerAwareInstanceRegistryImpl#init

DiscoveryClient#fetchRegistry

JerseyApplicationClient

AbstractJerseyEurekaHttpClient#getApplications

EurekaServerInitializerConfiguration

new RemoteRegionRegistry

AbstractJerseyEurekaHttpClient#register

从其他eureka节点拷贝服务注册列表

AbstractInstanceRegistry#postInit

PeerAwareInstanceRegistryImpl#scheduleRenewalThresholdUpdateTask

服务剔除

AbstractInstanceRegistry#initRemoteRegionRegistry

TransportClientFactories#newTransportClientFactory

DiscoveryClient#getAndStoreFullRegistry

@ConditionalOnBean(EurekaServerMarkerConfiguration.Marker.class)

SmartLifecycle，容器启动的时候自动调用start方法

PeerAwareInstanceRegistry#syncUp

响应缓存

EurekaHttpClientDecorator#getApplications

EurekaClientAutoConfiguration#eurekaServiceRegistry
