Spring integration 无法重命名SFTP远程目录中的临时文件

继续担任该职位-

我正在使用sftp:outbound channel adapter将文件上载到一个sftp服务器中。上传文件后，API无法重命名临时文件sample\u test.pgp。将写入sample\u test.pgp

在上传文件之前，我在sftp远程文件夹中验证了文件是否存在，并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，它在最后失败，出现了无效路径错误消息

如果我设置了使用临时文件名=false，它就可以工作，但如果有任何文件监视程序作业可能会拾取在远程服务器端加载的不完整文件，我不想设置此标志

这是我的配置

<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}"/>

请显示完整的配置

您的sftp用户是否已注册？如果不是，

/inbox/…

正在尝试操作服务器上的根目录，并且他可能没有相应的权限

---

尝试从远程目录中删除前导的

/

。

感谢Gary的回复。请在我的原始帖子中找到更新的配置。如果没有属性值，将不会有多大帮助。没有想法；很抱歉有些服务器被配置为不允许重命名（）。但如果我使用putty手动登录并尝试重命名它，它将非常有效。putty是

ssh

客户端，而不是

sftp

客户端；当您从命令行使用

sftp

时，它是否工作？此外，您的配置也有一些奇怪之处。

ls

的结果是一个

列表

，因此如果没有

，我看不出您的配置将如何工作。我希望

payload.getName（）

在一个列表负载上失败。你能在某处发布一个显示完整交互的调试日志吗？

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()
