如果我以分布式模式在两台不同的服务器上部署我的project war，那么它会有问题吗？因为在这两台服务器上，
FTP入站通道适配器将运行。然后两个适配器将读取同一文件两次。
请帮助我在分布式模式下设置此系统

编辑：

我已经在两台服务器上设置了我的
Spring集成
projectwar。它正在使用FTP入站通道适配器
。两台服务器的适配器
远程位置
指向相同的ftp文件位置。当我启动两台服务器时，两台服务器开始传输相同的文件并多次生成消息。我正在按照Gary的建议使用Redis元数据存储。
两台服务器上的我的
Ftp入站通道适配器
如下所示：



<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">
    <constructor-arg name="connectionFactory" ref="redisConnectionFactory"/>
</bean>

<bean id="fileSystemPersistantFilter" class="org.springframework.integration.file.filters.FileSystemPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"
    session-factory="ftpClientFactory" channel="ftpChannel"
    filter="ftpPersistantFilter"
    local-filter="fileSystemPersistantFilter" delete-remote-files="false"
    remote-directory="${ftp.remote_directory}/test/" local-directory="${ftp.local_directory}/test/"
    temporary-file-suffix=".writing" auto-create-local-directory="true">
    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>


第二台服务器正在生成具有不同消息ID的相同日志。
我是不是遗漏了什么？

我需要为此编写自定义筛选器吗


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"
    session-factory="ftpClientFactory" channel="ftpChannel"
    filter="ftpPersistantFilter"
    local-filter="fileSystemPersistantFilter" delete-remote-files="false"
    remote-directory="${ftp.remote_directory}/test/" local-directory="${ftp.local_directory}/test/"
    temporary-file-suffix=".writing" auto-create-local-directory="true">
    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>


我的问题是，它每天能处理大约500万个文件吗


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">

<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"

    filter="ftpPersistantFilter"

    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>


这取决于文件的大小和网络的带宽；使用Spring集成不太可能是一个因素


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">
    <constructor-arg name="connectionFactory" ref="redisConnectionFactory"/>
</bean>

<bean id="fileSystemPersistantFilter" class="org.springframework.integration.file.filters.FileSystemPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"
    session-factory="ftpClientFactory" channel="ftpChannel"
    filter="ftpPersistantFilter"
    local-filter="fileSystemPersistantFilter" delete-remote-files="false"
    remote-directory="${ftp.remote_directory}/test/" local-directory="${ftp.local_directory}/test/"
    temporary-file-suffix=".writing" auto-create-local-directory="true">
    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>


不过，您可能应该在处理后在本地删除文件，以避免大型目录扫描


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">
    <constructor-arg name="connectionFactory" ref="redisConnectionFactory"/>
</bean>

<bean id="fileSystemPersistantFilter" class="org.springframework.integration.file.filters.FileSystemPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"
    session-factory="ftpClientFactory" channel="ftpChannel"
    filter="ftpPersistantFilter"
    local-filter="fileSystemPersistantFilter" delete-remote-files="false"
    remote-directory="${ftp.remote_directory}/test/" local-directory="${ftp.local_directory}/test/"
    temporary-file-suffix=".writing" auto-create-local-directory="true">
    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>


为了避免集群中的重复，您需要使用由共享元数据存储支持的
ftppersistentAcceptonFileListFilter
，这样每个实例都将跳过由其他实例处理的文件


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">
    <constructor-arg name="connectionFactory" ref="redisConnectionFactory"/>
</bean>

<bean id="fileSystemPersistantFilter" class="org.springframework.integration.file.filters.FileSystemPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"
    session-factory="ftpClientFactory" channel="ftpChannel"
    filter="ftpPersistantFilter"
    local-filter="fileSystemPersistantFilter" delete-remote-files="false"
    remote-directory="${ftp.remote_directory}/test/" local-directory="${ftp.local_directory}/test/"
    temporary-file-suffix=".writing" auto-create-local-directory="true">
    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>

我刚刚测试了您的配置，没有发现任何问题。您确定两个实例使用相同的Redis服务器吗


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">

</int-ftp:inbound-channel-adapter>


如果运行
redis cli
，然后运行
monitor
，您应该会看到如下内容：


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

<bean name="metadataStore" class="org.springframework.integration.redis.metadata.RedisMetadataStore">

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter">

    temporary-file-suffix=".writing" auto-create-local-directory="true">
    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>

在本例中，远程目录有2个文件；前两行来自远程筛选器，后两行来自本地筛选器（设置初始值）


<bean id="redisMessageStore" class="org.springframework.integration.redis.store.RedisMessageStore">
    <constructor-arg ref="redisConnectionFactory"/>
</bean>

    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>

<bean id="ftpPersistantFilter" class="org.springframework.integration.ftp.filters.FtpPersistentAcceptOnceFileListFilter"> 
    <constructor-arg name="store" ref="metadataStore"/> <constructor-arg name="prefix" value="" />
</bean>
<int-ftp:inbound-channel-adapter id="ftpInboundAdapter"
    session-factory="ftpClientFactory" channel="ftpChannel"
    filter="ftpPersistantFilter"
    local-filter="fileSystemPersistantFilter" delete-remote-files="false"
    remote-directory="${ftp.remote_directory}/test/" local-directory="${ftp.local_directory}/test/"

    <int:poller fixed-rate="1000" max-messages-per-poll="-1" />
</int-ftp:inbound-channel-adapter>


然后你会看到一堆

（每次轮询一次-检查时间戳是否更改）。
但是，假设我的FTP服务器上有10个文件，我启动了
入站适配器
，然后它将所有文件的元数据存储到
元数据存储
，然后开始将文件从FTP传输到本地文件系统。传输了5个文件后，我重新启动了服务器，然后适配器并没有传输剩下的5个文件。在这种情况下我们应该怎么做？如果在复制文件6时出现异常，将从元数据存储中删除文件6-10。如果只是在复制文件时关闭服务器，文件将保留在存储中，您必须手动清理它们。由于文件系统不是事务性的（一般来说），因此没有什么可以做的。我在两台不同的服务器上设置了
FTP入站适配器
，两台服务器都配置为使用共享
Redis元数据存储
。当我启动两台服务器时，两台服务器都开始传输所有文件。之后，两台服务器都使用多个消息ID多次从这些文件生成消息。我正在使用
ftppersistentacceptancefilelistfilter
和
filesystemtempersistentaptacceptoncefilelistfilter
您需要显示配置和调试日志。编辑问题不要试图将其放在评论中。请对此进行更新？？？？
