Question

在sftp remote中-我有2个[ready]和[process]文件夹，我需要做的是首先将文件从ready移至处理，然后使用单个通道将该文件移至本地目录。请检查我的代码是否正确？我的代码可以正常工作，但是我怀疑首先将代码移到远程处理或本地文件夹中吗？

@Bean
public IntegrationFlow remoteToLocal() {
    return IntegrationFlows
            .from(Sftp.inboundAdapter(sftpSessionFactory())
                            .remoteDirectory(sftpProperties.getRemoteRootDir() + "/ready")
                            .regexFilter(FILE_PATTERN_REGEX)
                            .deleteRemoteFiles(true)
                            .localDirectory(new File(mmFileProperties.getMcfItes()+ mmFileProperties.getInboundDirectory()))
                            .preserveTimestamp(true)
                            .temporaryFileSuffix(".tmp"),
                    e -> e.poller(Pollers.fixedDelay(sftpProperties.getPollerIntervalMs()))
                            .id("sftpInboundAdapter"))
            .handle(Sftp.outboundAdapter(mmSftpSessionFactory())
                    .remoteDirectory(sftpProperties.getRemoteRootDir() + "/process")
                    .temporaryFileSuffix(".tmp"))

            .get();
}

请检查新代码，但是它不起作用

private StandardIntegrationFlow remoteToLocalFlow(final String localDirectory, final String remoteDirectoryProcessing, final String adapterName) {
        return IntegrationFlows
            .from(Sftp.inboundAdapter(mmSftpSessionFactory())
                            .remoteDirectory(remoteRootDir + remoteDirectoryProcessing)
                            .regexFilter(FILE_PATTERN_REGEX)
                            .deleteRemoteFiles(true)
                            .localDirectory(Paths.get(localDirectory).toFile())
                            .preserveTimestamp(true)
                            .temporaryFileSuffix(".tmp"),
                    e -> {
                        e.poller(Pollers.fixedDelay(mmSftpProperties.getPollerIntervalMs()))
                                .id(adapterName);
                    })
            .handle(m -> logger.trace("File received from sftp interface: {}", m))
            .handleWithAdapter(h -> h.sftpGateway(sftpSessionFactory(),AbstractRemoteFileOutboundGateway.Command.MV, "payload")
            .renameExpression(remoteRootDir + ready) 
            .localDirectoryExpression(remoteRootDir + process)).get(); }

看起来不错，但这不是最好的方法；您正在复制文件，将其删除并以其他名称发送回去。

改为使用SftpOutboundGateway with a MV (move) command。

您还可以使用网关列出和获取文件。
