Question

首先，我遇到以下错误：GenericFileOperationFailedException - Cannot change directory to: ..] 我通过在端点字符串中添加stepwise=false来解决此问题：

sftp://sales.data.com:22/data/100?fileName=20190410.dat.gz&password=xxxxxx&stepwise=false&username=UserName

此后，它失败并显示以下错误，并且我找不到有关解决此问题的任何相关信息。什么可能导致这里出现问题？

在使用方上使用readLock，使其等待文件完全通过FTP进行编辑。在Camel documentation for ftp中，找到以下选项：

readLock更改

这个想法是：告诉骆驼（Camel）在看到文件时不要读取文件，而要继续检查文件大小是否在增长。只要它保持增长，骆驼就会等待。您可以更改相关选项来确定等待时间等，等等。在该页面中搜索“ readLock”的所有提及内容以查找更多信息。

如何解决错误：org.apache.camel.component.file.GenericFileOperationFailedException：无法检索文件？
