Spring integration 春季整合：无法与动物园管理员进行领袖选举

我正在尝试从我的应用程序容器中选出领导者来完成一些任务

我编写了以下代码

@Configuration
@EnableIntegration
public class LeaderConfiguration {

  @Bean
  public LeaderInitiatorFactoryBean leaderInitiator(CuratorFramework client) {
   return new LeaderInitiatorFactoryBean()
        .setClient(client)
        .setPath("/app/test/")
        .setRole("app");
  }


  @Bean
  @Primary
  CuratorFrameworkFactoryBean curatorFramework() {
    return new CuratorFrameworkFactoryBean("127.0.0.1:2181");
  }

  @Bean
  @InboundChannelAdapter(channel = "attributeChannel", autoStartup = "false", poller = @Poller(fixedDelay = "100"))
  @Role("app")
  public Supplier<String> inboundChannelAdapter() {
    return () -> "app";
  }

  @Bean("attributeChannel")
  public MessageChannel attributeChannel() {
    return new DirectChannel();
  }

  @ServiceActivator(inputChannel = "attributeChannel", autoStartup = "false")
  public void listen(Object a) {
    System.out.println("I am leader");
  }

}

我当地的动物园管理员已经开始工作了

我不断收到错误，可能是我的连接设置错误

我做错了什么。

看起来像是

compile（“org.apache.curator:curator recipes:4.2.0”）

附带

org.apache.zookeer:zookeer:3.5.4-beta

要使它与zookeer

3.4.x

一起工作，我们需要遵循策展人框架的指示：

Curator 4.0以软兼容模式支持ZooKeeper 3.4.x集成。若要使用此模式，在将管理员添加到依赖项管理工具时，必须排除ZooKeeper

因此，包括

zookeeper

对

3.4.14

版本的依赖关系

---

嗯。看起来你也需要将它从

spring cloud zookeeper core

依赖项中排除。

我想知道你是否使用最新的zookeeper版本：@ArtemBilan。我使用的zookeeper 3.4.3与zookeeper集成5.1.4.0版本不兼容。我降级到5.0.2.RELEASE，然后开始正常工作。非常感谢
