Java 管理员与Zookeeper服务发现连接被强制关闭

我正在尝试使用馆长和动物园管理员进行服务发现

当我尝试注册我的服务时，会发生以下情况

2014-09-23 16:36:09,755 [myid:] - INFO  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@197] - Accepted socket connection from /127.0.0.1:52026

相关代码如下：（getDiscovery方法就是导致上述错误的方法）

以下是所需策展人框架的初始化

    CuratorFramework curatorFramework;
    curatorFramework = CuratorFrameworkFactory.builder()
        .connectionTimeoutMs(1000)
        .retryPolicy(new RetryNTimes(10, 500))
        .connectString(Config.address+":"+Config.port)
        .build();
    curatorFramework.start();
    new EnsurePath(Config.basePath).ensure(curatorFramework.getZookeeperClient());

jacksonInstanceSerializer如下所示：

    this.jacksonInstanceSerializer = instanceSerializerFactory.getInstanceSerializer(
        new TypeReference<ServiceInstance<InstanceDetails>>() {}
    );

this.jacksonInstanceSerializer=instanceSerializerFactory.getInstanceSerializer(
新类型引用（）{}
);

其中instanceSerializerFactory是：

public class InstanceSerializerFactory {
    private final ObjectReader objectReader;
    private final ObjectWriter objectWriter;

    public InstanceSerializerFactory(ObjectReader objectReader, ObjectWriter objectWriter) {
        this.objectReader = objectReader;
        this.objectWriter = objectWriter;
    }

    public <T> InstanceSerializer<T> getInstanceSerializer(
            TypeReference<ServiceInstance<T>> typeReference) {
        return new JacksonInstanceSerializer<T>(objectReader, objectWriter, typeReference);
    }

}

final class JacksonInstanceSerializer<T> implements InstanceSerializer<T> {
    private final TypeReference<ServiceInstance<T>> typeRef;
    private final ObjectWriter objectWriter;
    private final ObjectReader objectReader;

    JacksonInstanceSerializer(ObjectReader objectReader, ObjectWriter objectWriter,
                              TypeReference<ServiceInstance<T>> typeRef) {
        this.objectReader = objectReader;
        this.objectWriter = objectWriter;
        this.typeRef = typeRef;
    }

注意：实例详细说明了我试图注册的内容（服务名称和地址等）

连接似乎正在从客户端关闭。Zookeeper会话绑定到Zookeeper服务器和客户端之间的连接（在您的案例中使用curator）。最可能的情况是，客户端正在关闭，因此服务器正在识别此场景并关闭您的会话。

您似乎在使用发现实例后立即关闭它。这没有意义。

    CuratorFramework curatorFramework;
    curatorFramework = CuratorFrameworkFactory.builder()
        .connectionTimeoutMs(1000)
        .retryPolicy(new RetryNTimes(10, 500))
        .connectString(Config.address+":"+Config.port)
        .build();
    curatorFramework.start();
    new EnsurePath(Config.basePath).ensure(curatorFramework.getZookeeperClient());

    this.jacksonInstanceSerializer = instanceSerializerFactory.getInstanceSerializer(
        new TypeReference<ServiceInstance<InstanceDetails>>() {}
    );

public class InstanceSerializerFactory {
    private final ObjectReader objectReader;
    private final ObjectWriter objectWriter;

    public InstanceSerializerFactory(ObjectReader objectReader, ObjectWriter objectWriter) {
        this.objectReader = objectReader;
        this.objectWriter = objectWriter;
    }

    public <T> InstanceSerializer<T> getInstanceSerializer(
            TypeReference<ServiceInstance<T>> typeReference) {
        return new JacksonInstanceSerializer<T>(objectReader, objectWriter, typeReference);
    }

}

final class JacksonInstanceSerializer<T> implements InstanceSerializer<T> {
    private final TypeReference<ServiceInstance<T>> typeRef;
    private final ObjectWriter objectWriter;
    private final ObjectReader objectReader;

    JacksonInstanceSerializer(ObjectReader objectReader, ObjectWriter objectWriter,
                              TypeReference<ServiceInstance<T>> typeRef) {
        this.objectReader = objectReader;
        this.objectWriter = objectWriter;
        this.typeRef = typeRef;
    }
