这是我的路线 - ＆gt;

sftp://myftp:22?delay
=1h&delete=true&doneFileName=done&password=xxxxxx&sortBy=ignoreCase%3Afile%3Aname&stepwise=false&username=myUser

是的，有java.io.IOException：管道已关闭。我刚检查了camel-ftp的代码，它有代码来检查连接，但是如果我们不向服务器套接字发送一些字节，那么很难知道连接是否仍然打开。

解决方案可能是强制ftp客户端发送一些ping消息来检查连接是否仍然打开。

如果你想为ftp pull设置一个很长的延迟，那么解决方法是将 disconnect 选项设置为true以强制ftp端点重新启动新连接时重新启动FTP服务器。

我刚为它创建了a JIRA。
