Where to do context setup stuff in a guice enabled camel app

[dermoritz <ta...@hotmail.com>]

i am using guice in conjunction with "CamelModule" in my camel application
(standalone using Main). In my case i need to do some things on the context
before starting it:

context.addRoutePolicyFactory(startUpLogic);
context.getRegistry(JndiRegistry.class).bind(CepModule.LOOKUP_DATASOURCE,
ds);

But i am not sure where to put this lines. At the moment this lines are
added in constructor of my main RouteBuilder that is adding all other
RoutBuilders. (do context setup stuff in route builder feels wrong)
Alternativly i could put this lines into this method (mandatory if using
CepModule)
    @Provides
    @Inject
    private Set<RoutesBuilder> getRoutes(final RouteBuilder routes) 

I just would inject context but it also feels wrong to do this here. So is
there a good way/practice to hook into before starting and doing this kind
of setup?

thanks in advance

It’s not a good idea to setup the camel context inside the RouteBuilder, as it could have some side effect on the other RouteBuilder.

CamelContext support to inject the registry, but it doesn’t supper to addRoutePolicyFactory.
You may need to find other way to add the RoutePolicyFactory, such as extends the GuiceCamelContext to made the startUpLogic injectable.
