将远程文件下载到本地文件系统后,如何配置spring-integration-sftp来移动它?

我具有以下Kotlin配置,用于与远程服务器同步sftp文件。

@Bean
fun sessionFactory(): SessionFactory<ChannelSftp.LsEntry> {
    val factory = DefaultSftpSessionFactory(true)
    factory.setHost(sftpHost)
    factory.setPort(sftpPort.toInt())
    factory.setUser(sftpUser)
    factory.setPassword(sftpPasword)
    factory.setAllowUnknownKeys(true)
    return CachingSessionFactory<ChannelSftp.LsEntry>(factory)
}

@Bean
fun template(): SftpRemoteFileTemplate {
    return SftpRemoteFileTemplate(sessionFactory())
}

@Bean
fun sftpInboundFileSynchronizer(): SftpInboundFileSynchronizer {
    val fileSynchronizer = SftpInboundFileSynchronizer(sessionFactory())
    fileSynchronizer.setDeleteRemoteFiles(false)
    fileSynchronizer.setRemoteDirectory(sftpRemoteDirectoryDownload)
    fileSynchronizer.setFilter(SftpPersistentAcceptOnceFileListFilter(PropertiesPersistingMetadataStore(), "downloaded"))
    return fileSynchronizer
}

@Bean
@InboundChannelAdapter(channel = "download", poller = [Poller(cron = "0/5 * * * * *")])
fun sftpMessageSource(): MessageSource<File> {
    val source = SftpInboundFileSynchronizingMessageSource(sftpInboundFileSynchronizer())
    source.setLocalDirectory(File(sftpLocalDirectoryDownload))
    source.setAutoCreateLocalDirectory(true)
    source.setLocalFilter(FileSystemPersistentAcceptOnceFileListFilter(PropertiesPersistingMetadataStore(), "downloaded"))
    return source
}

@Bean
@ServiceActivator(inputChannel = "download", outputChannel = "move")
fun resultFileHandler(): MessageHandler {
    return MessageHandler { message -> publisher.handleMessage(message) }
}

@Bean
@ServiceActivator(inputChannel = "move")
fun sftpOutboundGateway(sessionFactory: SessionFactory<ChannelSftp.LsEntry>): SftpOutboundGateway {
    val gateway = SftpOutboundGateway(sessionFactory, "mv", "payload")
    gateway.setOutputChannelName("errorChannel")
    return gateway
}

我想做的是从远程服务器下载文件后移动文件;但是,我还没有找到一种可行的方法。大多数示例都使用xml配置。

一切正常,可以处理resultFileHandler方法调用,在这里我可以处理本地文件;但是MessageHandler没有发送到move通道。我想知道我在想什么。

考虑改用3个出站网关

worksheet.merge_range('A3:A10', 'Merged Range', merge_format)
worksheet.merge_range('A10:A17', 'Merged Range', merge_format)

ftp sample显示了类似的技术,但是使用RM而不是MV(尽管使用XML配置是因为它已经很老了。)
