Camel routeTemplate
Hello,
i am trying to use routeTemplates within karaf with DSL but i don't find
any examples how to create routes with XML DSL. Also
https://camel.apache.org/manual/latest/route-template.html#_creating_routes_from_properties_file
seems not wo work in karaf.
Any suggestions?
br,
Matthias

Hello again,
I looked into the source..
What do you think about adding RouteTemplateParameterSource interface to
public class BlueprintPropertiesSource extends ServiceSupport implements
PropertiesSource?
Otherwise I would work with a simple service like
MyRouteTemplateParameterSource implements RouteTemplateParameterSource.
But How can I trigger the reload of a blueprint? The only "hackaround" i
could think of would be something like this
<cm:property-placeholder
persistent-id="same-config-which-configs-my-MyRouteTemplateParameterSource
" update-strategy="reload"/> ?
Or is there a better mechanism to restart a blueprint bundle with an event
e.g. EventAdmin? i only found one point in code where
blueprintContainer.reload(); is called.
What do you think?
BR

Hello Jb,
i wasn't looking for the basic stuff... I tried this:
And yes i configured cm:property-paceholder from osgi config (Which is
working with reloading) but this here doesn't work
<camelContext>
<routeTemplate id="myTemplate">
<templateParameter name="name"/>
<templateParameter name="greeting"/>
<templateParameter name="myPeriod" defaultValue="3s"/>
<route>
<from uri="timer:{{name}}?period={{myPeriod}}"/>
<setBody><simple>{{greeting}} ${body}</simple></setBody>
<log message="${body}"/>
</route>
</routeTemplate></camelContext>
And in spring application.props you can do something like the following
what i added to the osgi config. Its quite handy when you want to create
multiple kafka consumer within one context e.g.
camel.route-template[0].template-id=myTemplatecamel.route-template[0].name=Jeancamel.route-template[0].greeting=cheese
camel.route-template[1].template-id=myTemplatecamel.route-template[1].name=Matthiascamel.route-template[1].greeting=wurst
Btw i had an outher Caml regarded question .. injecting karaf JAAS
into jetty and kubernetes clustering support.
BR,
Matthias
