Question

我有一个文件：inbound-channel-adapter，用于轮询目录中的文件，然后通过SFTP将其发送到服务器。上传后（工作正常），需要删除原始文件;如何上传原始文件后如何删除原始文件？在文件：outbound-channel-adapter中，我可以设置一个属性来自动删除文件。

<file:inbound-channel-adapter 
    id="incomingFiles"      
    channel="myFiles"       
    directory="file:/tmp/kots">
    <int:poller id="poller" fixed-delay="1000"/>
</file:inbound-channel-adapter>

<int:channel id="myFiles"/>

....

<sftp:outbound-channel-adapter 
    id="sftpOutboundAdapter"
    channel="myFiles"
    charset="UTF-8"     
    remote-directory="/tmp/testing"     
    session-factory="sftpSessionFactory"/>

Transaction Synchronization适合您：

<file:inbound-channel-adapter 
    id="incomingFiles"      
    channel="myFiles"       
    directory="file:/tmp/kots">
    <int:poller id="poller" fixed-delay="1000">
         <int:transactional transaction-manager="transactionManager" synchronization-factory="syncFactory" />
    </int:poller>
</file:inbound-channel-adapter>


<int:transaction-synchronization-factory id="syncFactory">
    <int:after-commit expression="payload.delete()" channel="nullChannel"/>
</int:transaction-synchronization-factory>

开箱即用的transactionManager可能是org.springframework.integration.transaction.PseudoTransactionManager。
