使用 Apache Camel 删除文件

Question

I just tried out a Camel route to move such files which are modified in the last 10 days from input directory to output directory and after the transfer of all the files from input directory are deleted as I set the option delete=true.

Date tenDaysBack = new Date(System.currentTimeMillis() - 10*8640000);
from("file:data/input?noop=true")
    .filter(header("CamelFileLastModified").isGreaterThan(tenDaysBack))
    .to("file:data/output");

This worked fine. But now what I want to do is keep the files that were modified in the last 10 days in the input directory only and delete the rest. How can we do it using Camel?

Answer 1

Use parameter filterFile option of File component instead of filter EIP

To look for file older than 10 days, try filterFile=${date:file:yyyyMMddHHmm} <= ${date:now-240h:yyyyMMddHHmm}

• ${date:file:yyyyMMddHHmm} - file last modified time (up to minutes level)
• ${date:now-240h:yyyyMMddHHmm} - time of current minus 10 days (up to minutes level)
