We have several file routes that have several 'when' clauses in a 'choice'
element (XML config). I need a way to let the user disable some of the
'when' options at runtime. Each 'when' clause currently just has a 'to'
file URI.
Note I can't just stop the route that picks up the file at the above 'to'
URI because if I did that the files would continue to be produced at the
'to' URL.
I need to somehow disable the 'when' so that the files never get directed
anywhere because we have an ortherwise/stop clause in the choice...so files
that are not recognized go nowhere which is the correct behavior.
I could possibly wrap each of the when elements with another choice/when
that simply checks a bean if the 'when' is enabled but it feels like Camel
might already handle this more elegantly.
Part 2:
If I go with the custom bean idea, is there a way to pass method parameters
to the bean inline in the simple (or some other) expression? Currently I
set the method parameter in a camel header and then the bean gets it via
annotations but would prefer to pass it directly if possible. E.g.
currently I have this just to check if the when is enabled.
<setHeader headerName="CamelRouteName">
<simple>ingestXdomain_OC</simple>
</setHeader>
<choice>
<when id="ingestXdomain_OC_Enabled">
<simple>bean:routeEnabled?method=isEnabled</simple>
<to
uri="file://{{gangplank.home}}/work/ingestXdomain/OC/?tempFileName=${file:name}.partial"/>
</when>
<otherwise>
<stop/>
</otherwise>
</choice>
