Re: Route Template and dependency to Spring Boot Component Order initialization

[Claus Ibsen <cl...@gmail.com>]

Hi

Sorry for the late reply.
Yeah we should make using this out of the box better on SB.
Can you create a JIRA ticket.

On top of my mind, then Spring Boot may have some annotation/interface that
can be implemented to specify priority/ordering.
And we have that in Camel as well with org.apache.camel.Ordered (I think).

Because if you use RouteBuilder to build route templates then Camel cannot
know just by the class that its template or not.
So we may also consider some interface where you can mark the class to say
it has templates, and therefore should be loaded first.
