1.结论：

Eureka根据IP地址将defaultZone: http://peer2:8002/eureka/,http://peer1:8001/eureka/生成不同的集合

2.源码分析

2.1.ClusterResolver集群解析器负责解析配置的EurekaServer地址

eureka:client:serviceUrl:defaultZone: http://peer2:8002/eureka/,http://peer1:8001/eureka/public interface ClusterResolver<T extends EurekaEndpoint> {String getRegion();List<T> getClusterEndpoints();
}

2.2 EurekaClient使用了ClusterResolver的两个实现类ZoneAffinityClusterResolver和AsyncResolver来实现注册功能

public class ZoneAffinityClusterResolver implements ClusterResolver<AwsEndpoint> {public class AsyncResolver<T extends EurekaEndpoint> implements ClosableResolver<T> {

2.3.在DiscoveryClient初始化的时候实例化ZoneAffinityClusterResolver，然后调用getClusterEndpoints，之后将值赋值到AsyncResolver（ClosableResolver）供服务使用，将ClosableResolver赋值给EurekaHttpClientFactory

//初始化DiscoveryClient
@Singleton
public class DiscoveryClient implements EurekaClient {private final EurekaTransport eurekaTransport;private static final class EurekaTransport {private ClosableResolver bootstrapResolver;private TransportClientFactory transportClientFactory;}@InjectDiscoveryClient(ApplicationInfoManager applicationInfoManager, EurekaClientConfig config, DiscoveryClientOptionalArgs args,Provider<BackupRegistry> backupRegistryProvider) {eurekaTransport = new EurekaTransport();scheduleServerEndpointTask(eurekaTransport, args);                }private void scheduleServerEndpointTask(EurekaTransport eurekaTransport,DiscoveryClientOptionalArgs args) {//实例化ZoneAffinityClusterResolver，然后调用getClusterEndpoints，之后将值赋值到AsyncResolver（ClosableResolver）eurekaTransport.bootstrapResolver = EurekaHttpClients.newBootstrapResolver(clientConfig,transportConfig,eurekaTransport.transportClientFactory,applicationInfoManager.getInfo(),applicationsSource);     if (clientConfig.shouldRegisterWithEureka()) {EurekaHttpClientFactory newRegistrationClientFactory = null;EurekaHttpClient newRegistrationClient = null;try {//将ClosableResolver赋值给EurekaHttpClientFactorynewRegistrationClientFactory = EurekaHttpClients.registrationClientFactory(eurekaTransport.bootstrapResolver,eurekaTransport.transportClientFactory,transportConfig);newRegistrationClient = newRegistrationClientFactory.newClient();} catch (Exception e) {logger.warn("Experimental transport initialization failure", e);}eurekaTransport.registrationClientFactory = newRegistrationClientFactory;eurekaTransport.registrationClient = newRegistrationClient;}                      }
}public final class EurekaHttpClients {public static ClosableResolver<AwsEndpoint> newBootstrapResolver(final EurekaClientConfig clientConfig,final EurekaTransportConfig transportConfig,final TransportClientFactory transportClientFactory,final InstanceInfo myInstanceInfo,final ApplicationsResolver.ApplicationsSource applicationsSource){// if all else fails, return the defaultreturn defaultBootstrapResolver(clientConfig, myInstanceInfo);}static ClosableResolver<AwsEndpoint> defaultBootstrapResolver(final EurekaClientConfig clientConfig,final InstanceInfo myInstanceInfo) {String[] availZones = clientConfig.getAvailabilityZones(clientConfig.getRegion());String myZone = InstanceInfo.getZone(availZones, myInstanceInfo);//初始化new ZoneAffinityClusterResolverClusterResolver<AwsEndpoint> delegateResolver = new ZoneAffinityClusterResolver(new ConfigClusterResolver(clientConfig, myInstanceInfo),myZone,true);//调用ZoneAffinityClusterResolver的getClusterEndpoints计算新的initialValueList<AwsEndpoint> initialValue = delegateResolver.getClusterEndpoints();if (initialValue.isEmpty()) {String msg = "Initial resolution of Eureka endpoints failed. Check ConfigClusterResolver logs for more info";logger.error(msg);}//将initialValue值赋值给AsyncResolverreturn new AsyncResolver<>(EurekaClientNames.BOOTSTRAP,delegateResolver,initialValue,1,clientConfig.getEurekaServiceUrlPollIntervalSeconds() * 1000);}}public class ZoneAffinityClusterResolver implements ClusterResolver<AwsEndpoint> {private static final Logger logger = LoggerFactory.getLogger(ZoneAffinityClusterResolver.class);private final ClusterResolver<AwsEndpoint> delegate;private final String myZone;private final boolean zoneAffinity;/*** A zoneAffinity defines zone affinity (true) or anti-affinity rules (false).*/public ZoneAffinityClusterResolver(ClusterResolver<AwsEndpoint> delegate, String myZone, boolean zoneAffinity) {this.delegate = delegate;this.myZone = myZone;this.zoneAffinity = zoneAffinity;}@Overridepublic String getRegion() {return delegate.getRegion();}@Overridepublic List<AwsEndpoint> getClusterEndpoints() {List<AwsEndpoint>[] parts = ResolverUtils.splitByZone(delegate.getClusterEndpoints(), myZone);List<AwsEndpoint> myZoneEndpoints = parts[0];List<AwsEndpoint> remainingEndpoints = parts[1];List<AwsEndpoint> randomizedList = randomizeAndMerge(myZoneEndpoints, remainingEndpoints);if (!zoneAffinity) {Collections.reverse(randomizedList);}if (logger.isDebugEnabled()) {logger.debug("Local zone={}; resolved to: {}", myZone, randomizedList);}return randomizedList;}private static List<AwsEndpoint> randomizeAndMerge(List<AwsEndpoint> myZoneEndpoints, List<AwsEndpoint> remainingEndpoints) {if (myZoneEndpoints.isEmpty()) {return ResolverUtils.randomize(remainingEndpoints);}if (remainingEndpoints.isEmpty()) {return ResolverUtils.randomize(myZoneEndpoints);}List<AwsEndpoint> mergedList = ResolverUtils.randomize(myZoneEndpoints);mergedList.addAll(ResolverUtils.randomize(remainingEndpoints));return mergedList;}
}

2.4.ResolverUtils的randomize方法，根据IP地址生成不同的集合（修改集合顺序）。

public final class ResolverUtils {public static <T extends EurekaEndpoint> List<T> randomize(List<T> list) {List<T> randomList = new ArrayList<>(list);if (randomList.size() < 2) {return randomList;}Random random = new Random(LOCAL_IPV4_ADDRESS.hashCode());int last = randomList.size() - 1;for (int i = 0; i < last; i++) {int pos = random.nextInt(randomList.size() - i);if (pos != i) {Collections.swap(randomList, i, pos);}}return randomList;}}

3.实验

}

3.2实验2,同一ip下的应用在相同的Eureka上

背景：
背景一:一个主机Ip地址172.16.20.140

根据实验一172.16.20.140将会生成以下集合，ip上的实例将首先注册到peer1
172.16.20.140[http://peer1:8001/eureka/, http://peer2:8002/eureka/]

背景二:两个Eureka

application-peer1.yml
spring:application:name: eurekaserver:port: 8001eureka:instance:appname: ${spring.application.name}hostname: peer1client:registerWithEureka: falsefetchRegistry: falseserviceUrl:defaultZone: http://peer2:8002/eureka/application-peer2.ymlspring:application:name: eurekaserver:port: 8002eureka:instance:appname: ${spring.application.name}hostname: peer2client:registerWithEureka: falsefetchRegistry: falseserviceUrl:defaultZone: http://peer1:8001/eureka/

背景三:两个User实例注册到两个Eureka

user实例1：
spring:application:name: spring-cloud-userserver:port: 8082eureka:client:serviceUrl:defaultZone: http://peer2:8002/eureka/,http://peer1:8001/eureka/user实例2：
spring:application:name: spring-cloud-userserver:port: 8083eureka:client:serviceUrl:defaultZone: http://peer2:8002/eureka/,http://peer1:8001/eureka/

观察1:启动两个Eureka，启动三个User实例观察是否注册到Peer1

观察结果:user两个实例都注册到了Peer1上

观察2:停止Peer2，观察是否两个User实例不收到影响，观察完成启动peer2

观察结果:peer2节点停止，两个User实例没有受到影响

观察3:停止Peer1，观察是否出现Peer1连接失败，重新连接到Peer2

观察结果：peer1节点停止，两个User实例都出现了连接peer1失败，重现建立peer1连接，再次失败，最后建立Peer2连接的情况。
