Java 使用zookeper服务器的群集环境中的FTP入站适配器

我有一个FTP入站适配器，它将部署在tomcat的多个实例上。问题是，所有实例都将从远程目录中提取文件，但我需要一个文件只提取一次，而不是由所有实例提取。因此，我使用Zookeeper元数据存储，但它在启动时给了我错误

错误

我的问题现在已经解决了。将ftpperAssistanceAcceptonFileListFilter的constructor参数从foo/bar/更改为下面提到的空字符串代码后，问题得到了解决

<beans:bean class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter">
                    <beans:constructor-arg name="store" ref="metadataStore"/>
                    <beans:constructor-arg value=""/>
</beans:bean>

您只需要

spring集成zookeeper

就可以了。但无论如何，堆栈跟踪与配置无关。堆栈跟踪是否包含目标

@Configuration

中的问题在哪里的信息？通过将POM条目更改为spring integration zookeeper，我的问题已得到解决，感谢Artem BilanI有一个查询我现在应该向CuratorFrameworkFactoryBean传递什么值我正在传递下面的zookeeper端口是代码。但是，在zookeeper元数据存储中添加值时，它给出了error.keeperrorcode=NoNode for/SpringIntegration元数据存储/foo/bar/20160626S001\u 20160626.xml编辑有问题老实说，我不喜欢你的

“0.0.0.0

IP。如何放置ZK节点的真实IP地址？当传递我机器的IP地址时，因为我在本地机器上运行ZK服务器，所以它也会给出相同的错误。您只需要
