Spring integration 使用出站网关删除文件失败,spring-integration,jsch,Spring Integration,Jsch,我正在尝试使用sftp出站网关删除远程sftp上的特定日志文件 <int-sftp:outbound-gateway id="removeSourceGateway" session-factory="sftpCachingSessionFactory" reply-channel="outputChannel"

我正在尝试使用sftp出站网关删除远程sftp上的特定日志文件

<int-sftp:outbound-gateway id="removeSourceGateway"
                               session-factory="sftpCachingSessionFactory" 
                               reply-channel="outputChannel"
                               request-channel="afterSuccessBackupChannel"
                               requires-reply="false"
                               command="ls"
                               expression="'/export/logs/'"
                               remote-directory="${sftp.remote.dir}">
</int-sftp:outbound-gateway>

为了使这个问题更加复杂，每当我使用WinSCP连接到SFTP并使用完全相同的帐户时，我就能够完全删除远程文件

干杯，杰斯

未能删除文件：4:失败

不幸的是，在本例中，

com.jcraft.jsch

库（用于sftp）中的异常有点神秘（

4:Failure

）

4表示：

SSH_FX_FAILURE
  is a generic catch-all error message; it should be returned if an
  error occurs for which there is no more specific error code
  defined.

…深入研究jsch代码，我觉得这个状态是由服务器返回的。服务器日志中有什么内容吗

如果没有，您可能必须使用wireshark或类似工具来找出服务器不喜欢rm请求的地方
