camel-ftp间歇性问题

Question

我使用camel-ftp组件将文件上传到服务器。我随机得到以下异常，ftp突然停止可能是什么问题。感谢任何指针。 我使用的骆驼版本是2.10.1

Answer 1

由于您提到您有时可以成功执行操作，因此可能不存在权限问题。不确定它是否可能是存储空间问题等。

我建议最好的方法是尝试通过您正在使用的版本的源代码进行调试。您将在org.apache.camel.component.file.remote.FtpOperations Java类中发现异常，并且IOException将被包含在那里。

然而，话虽如此 - 您也可以考虑使用全局错误处理程序。这篇文章解释了如何：http://java.dzone.com/articles/camel-exception-handling。它可以帮助理解究竟出了什么问题。
