我正在使用 sftp：outbound-channel-adapter 将文件上传到其中一个sftp服务器。上传文件后，API无法将临时文件 sample_test.pgp.writing 重命名为 sample_test.pgp 。

在上传文件之前，我在sftp远程文件夹中验证了文件存在且远程文件夹完全为空。

当我查看调试级别日志时，我可以看到下面的消息，并且最后因无效路径错误消息而失败。

如果我设置 use-temporary-file-name = false ，但是如果有任何文件观察程序作业可能会拾取加载的不完整文件，我不想设置此标志。远程服务器端。

以下是我的配置 

<int:gateway id="file.upload.gateway"
    service-interface="ftp.outbound.FTPUploadGateway"
    default-request-channel="ftp.uploadgateway.request.channel"
    default-reply-channel="ftp.uploadgateway.response.channel" />

<int:filter 
    input-channel="ftp.uploadgateway.request.channel" 
    output-channel="ftp.file.exist.outbound.channel" 
    discard-channel="upload.file.to.sftp"
    expression="${ftp.outbound.remote.file.check.flag:false}">
</int:filter>

<sftp:outbound-channel-adapter id="sftpOutboundAdapter"
    session-factory="sftpSessionFactory"
    channel="upload.file.to.sftp"
    charset="UTF-8"
    remote-directory="${ftp.outbound.remote.directory}"
    use-temporary-file-name="${ftp.outbound.use.temporary.filename:true}"
    remote-filename-generator-expression="${ftp.outbound.remote.filename.expression}"/>

以下是属性值

ftp.outbound.remote.file.check.flag=false
ftp.outbound.remote.directory=/inbox/
ftp.outbound.use.temporary.filename=true
ftp.outbound.remote.filename.expression=payload.getName()

答案 0 :(得分：0)

请显示完整的配置。

你的sftp用户是否被chrooted？如果不是/inbox/...正试图操纵服务器上的根目录，并且他可能没有权限。

尝试从远程目录中删除前导/。
