同步工厂删除sftp：inbound-channel-adapter的文件夹

Question

I have this issue where the first time this code is processed, it works well, but then the second time (first and second run is based on the set cron), it looks for a file in the failed folder and then deletes the success folder and copies it into the failed folder. I have no idea why this is happening??

<int-sftp:inbound-channel-adapter

    session-factory="sftpSessionFactory"

    local-directory="${local.download.folder}"

    channel="InboundChannel"
    filter="CompositeIncomingFilesFilter"
    auto-startup="true">
    <int:poller cron="*/60 * * * * ?" error-channel="PollerErrorChannel">
        <int:transactional transaction-manager="transactionManager" synchronization-factory="syncFactory" />
    </int:poller>
</int-sftp:inbound-channel-adapter>

My logs display the following:

Answer 1

and then it moves the folder with the file under failure

OK. So, when you rename a /success directory to something else, it disappears and, of course, you can't write to the /success anymore. You have to have it to be created in advice for writing files into it. You need to consider to rename each file individually if you don't have control over /success directory created before writing files.
