zuul的loadbalance的代碼

關於超時參數的代碼：

org.springframework.cloud.netflix.ribbon.support.AbstractLoadBalancingClient

@Override
public void initWithNiwsConfig(IClientConfig clientConfig) {
   super.initWithNiwsConfig(clientConfig);
   this.connectTimeout = clientConfig.getPropertyAsInteger(
         CommonClientConfigKey.ConnectTimeout,
         DefaultClientConfigImpl.DEFAULT_CONNECT_TIMEOUT);
   this.readTimeout = clientConfig.getPropertyAsInteger(
         CommonClientConfigKey.ReadTimeout,
         DefaultClientConfigImpl.DEFAULT_READ_TIMEOUT);
   this.secure = clientConfig.getPropertyAsBoolean(CommonClientConfigKey.IsSecure,
         false);
   this.followRedirects = clientConfig.getPropertyAsBoolean(
         CommonClientConfigKey.FollowRedirects,
         DefaultClientConfigImpl.DEFAULT_FOLLOW_REDIRECTS);
   this.okToRetryOnAllOperations = clientConfig.getPropertyAsBoolean(
         CommonClientConfigKey.OkToRetryOnAllOperations,
         DefaultClientConfigImpl.DEFAULT_OK_TO_RETRY_ON_ALL_OPERATIONS);
}

ZoneAwareLoadBalancer

public class ZoneAwareLoadBalancer<T extends Server> extends DynamicServerListLoadBalancer<T> {

查了好久才知道在這個類的updateAllServerList中更新的服務列表。 DynamicServerListLoadBalancer

@VisibleForTesting
public void updateListOfServers() {
        List servers = new ArrayList();
        if (serverListImpl != null) {
            servers = serverListImpl.getUpdatedListOfServers();
            LOGGER.debug("List of Servers for {} obtained from Discovery client: {}",
                    getIdentifier(), servers);

            if (filter != null) {
                servers = filter.getFilteredListOfServers(servers);
                LOGGER.debug("Filtered List of Servers for {} obtained from Discovery client: {}",
                        getIdentifier(), servers);
            }
        }
        updateAllServerList(servers);
}

protected void updateAllServerList(List ls) {
        // other threads might be doing this - in which case, we pass
        if (serverListUpdateInProgress.compareAndSet(false, true)) {
            for (T s : ls) {
                s.setAlive(true); // set so that clients can start using these
                                  // servers right away instead
                // of having to wait out the ping cycle.
            }
            setServersList(ls);
            super.forceQuickPing();
            serverListUpdateInProgress.set(false);
        }
    }
