我们使用Spring Integration MessageChannel API将请求文件发布到FTP位置。在此过程中，文件已成功发送，但在此过程中我们收到MessageDeliveryException。 PFB堆栈跟踪供您参考。寻找解决方案。请指导。
注意：Exception表示它试图删除，但我们并没有尝试删除。

答案 0 :(得分：0)
让我们来看看StackTrace的近距离！
Caused by: org.springframework.core.NestedIOException: Failed to remove file: 3: Permission denied.
at org.springframework.integration.sftp.session.SftpSession.remove(SftpSession.java:83)
at org.springframework.integration.sftp.session.SftpSession.rename(SftpSession.java:194)
所以，完全通过rename你做remove :-)。
这是因为：
if (logger.isDebugEnabled()) {
logger.debug("Initial File rename failed, possibly because file already exists. Will attempt to delete file: "
+ pathTo + " and execute rename again.");
}
我猜你也没有权限重命名文件。
rename操作仅在RemoteFileTemplate时从useTemporaryFileName == true启动。
因此，要解决您的问题，请尝试将其配置为use-temporary-file-name="false"上的<int-sftp:outbound-channel-adapter>
