我们有一个代理服务，它从 JasperReports 服务器下载 pdf 文件，然后执行 vfs:ftps 将 pdf 上传到 FTP 服务器。下载部分工作得很好，但我们正在努力处理上传部分。这是我们的问题：

启动代理服务时，我们收到以下 WARN 消息（注意我们在配置中确实有一个参数 FileURI）：

WARN PollTableEntry transport.vfs.FileURI parameter is missing in the proxy service configuration

并且在运行请求时，我们得到了如下异常：

我想知道这是否是代理配置中的潜在错误或任何错误。

请帮忙，谢谢！

这是代理配置 xml：

你定义了transport.vfs.FileNamePattern参数吗？

按照这个示例
