HOW: Apache Camel, Regex match files

Question

im experimenting in getting camel to do some file operations and pass them through the activeMQ broker, ive taken this project over from a guy who recently quit.

wha

Answer 1

In the implementation of name matching, the following code is used:

if (ObjectHelper.isNotEmpty(endpoint.getInclude())) {
    if (!name.matches(endpoint.getInclude())) {
        return false;
    }
}

So you can test which regular expression you should use. In you case, I think .*2280\\.xsl is what you should use.

Answer 2

Use the include option that uses Java regular expression:

include=.*2280\\.xsl

Please, mind the \\ before the dot .

Alternatively, use antInclude:

antInclude=*2280.xsl

Answer 3

Yeah you need to use the include/exclude/filter option if you want to filter out files based on patterns. The fileName option is for a single file.

So in your case, remove fileName option and replace it with include=.*2280.xsl. Mind that the include is based on Java regular expressions, so we use dot star to indicate wildcard. More details here: https://camel.apache.org/components/latest/file-component.html. The ftp component inherits 99% of the options of the file component, so that is why I refer to the file wiki page.

Answer 4

For that kind of filtering I recommend to use the GenericFileFilter
