推荐答案

文件连接器未下载数据，您是否与HTTP连接器混淆了?还是您是说Mule文件传输在文件生产者仍在复制文件的同时拾取了文件?

The file connector doesn't download data, are you mixing up with the HTTP connector? Or do you mean the Mule file transport picks-up a file while it is still being copied by the file producer?

如果是后者，最好的选择是将文件写入一个临时位置，然后将其移动到Mule拾取文件夹中，因为移动文件是原子操作.

If the latter, the best option is to write to file into a temporary location then move it to the Mule pick-up folder because moving a file is an atomic operation.

或者，您可以在文件连接器上使用fileAge属性，将Mule配置为仅拾取比指定时间更早的文件.仅当您了解文件编写器写入文件所花费的最长时间时，此方法才有效.

Alternatively, you can use the fileAge attribute on the file connector to configure Mule to only pick-up files that are older than the specified age. This can work only if you have an idea of the maximum time it takes the file writer to write the file.
