Question

我试图让Eureka客户端的故障转移行为正常工作并收到以下异常。 Eureka server1已关闭，我希望它能够故障转移到Eureka server2。应用程序意识到服务器1已关闭并尝试使用故障转移，但在代码中到达此位置并引发异常，因为备份注册表未定义。

2016-07-08T14:25:41.369Z WARN 0 [main] com.netflix.discovery.DiscoveryClient: Using default backup registry implementation which does not do anything. 2016-07-08T14:25:41.370Z WARN 0 [main] com.netflix.discovery.DiscoveryClient: Cannot fetch applications from apps although backup registry was specified java.lang.UnsupportedOperationException: Backup registry not implemented. at com.netflix.discovery.NotImplementedRegistryImpl.fetchRegistry(NotImplementedRegistryImpl.java:15) at com.netflix.discovery.DiscoveryClient.fetchRegistryFromBackup(DiscoveryClient.java:1811)

我的bootstrap.yml

eureka:
  client:  
    fetchRegistry: true
    service-url:
      defaultZone: https://server1/eureka/,https://server2/eureka/

Eureka Client中的这条线路正在发生故障。

private void fetchRegistryFromBackup() {
    try {
        @SuppressWarnings("deprecation")
        BackupRegistry backupRegistryInstance = newBackupRegistryInstance();
        if (null == backupRegistryInstance) { // backward compatibility with the old protected method, in case it is being used.
            backupRegistryInstance = backupRegistryProvider.get();
        }

        if (null != backupRegistryInstance) {

您可以尝试以下配置：

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    availability-zones:
      us-east-1: us-east-1a,us-east-1b
    region: us-east-1
    service-url:
      us-east-1a: http://<server1>/eureka/
      us-east-1b: http://<server2>/eureka/
