骆驼：filterFile DSL示例

Question

I want to use filterFile inside my camel route.

I have route like this:

from(String.format("sftp://%s@%s:%d/%s?password=%s&delete=true&readLock=changed&delay=%s,
                systemSettingsService.getSystemSettings().getSftpUserName(),
                systemSettingsService.getSystemSettings().getSftpHost(),
                systemSettingsService.getSystemSettings().getSftpPort(),
                systemSettingsService.getSystemSettings().getSftpSourcePathDestWorking(),
                systemSettingsService.getSystemSettings().getSftpPassword(),
                systemSettingsService.getSystemSettings().getSftpPollPeriod()))...

I have read file2 doc

Here is written:

Camel 2.18: Filters the file based on Simple language. For example to filter on file size, you can use ${file}:size > 5000.

But I don't understand where should I use this simple language.

Answer 1

I think the docs have made a typo. It would probably look something like this: from(String.format("sftp://%s@%s:%d/%s?filterFile=$simple{file:size} > 5000&delete=true..."))
