parameter types in RouteTemplateDefinition
Hi all,
I’ve a Question About the usage of Route templates (Camel-3.7.0).
As far as I see, it is possible to provide every kind of object as a paramter.
But within the template, it seems to me, that those Parameters are
only processed as Strings.
So my question:
Is there a way/best practice to provide object parameters, to e.g. a
startup order or route configurable error handler could be provided?
Maybe I miss something, but I could not find anything about it within
the documentation
(https://camel.apache.org/manual/latest/route-template.html)?
Btw: Using the route templates is a really great feature!
Thanks,
Joerg

Hi Jorg
Yeah that is a good question. At first route templates is designed to
be simple from the beginning.
Can you try with
errorHandler(new ErrorHandlerBuilderRef("{{my-error-handler-ref}}"));

Hi Claus,
thanks for your response.
I agree, just to use String literals.
But maybe you can tell me what's the best way to add a route-specific
errorhandler?
I solved my issue by doing it the following way:
ModelCamelContext modelCamelContext =
camelContext.adapt(ModelCamelContext.class);
RouteDefinition routeDefinition =
modelCamelContext.getRouteDefinition("my-templated-route-id");
if (routeDefinition != null)
routeDefinition.setErrorHandlerRef("my-error-handler-ref");
This seems to me, quite complicate, so maybe there is a better way to
do, which I'm not aware of?
Or maybe it would be a good improvement (handle this like the routeId)
for an upcoming release?
Kind regards,
Jörg

Hi
The template parameters are intended as text based placeholders,eg for
string, numbers, booleans, etc.
If you need to pass in objects, then it should be as reference to
objects to use in the registry via their bean id.
