Claus Ibsen commented on CAMEL-2650:
------------------------------------
Using @Produce or other Camel injected services will not consider singleton or
prototype scope beans. For prototype scoped a WARN is logged about the need to
manually stop the service after usage."
trunk: 934731.
> @Produce and @Consume injected on prototype beans needs a mechanism for
> automatic stopping when no longer in use

>
> This only applies for prototype scoped POJOs which uses @Produce or @Consume
> to inject a Camel Producer/Consumer.
> As the prototype scoped POJO is short lived and there could potentially be
> created many of those POJOs.
> Then @Produce / @Consume will inject new instances of Producer / Consumer as
> well.
> And since there is no standard way of knowing when the POJO is no longer in
> need, which is where we can to stop the Producer/Consumer.
> For singleton scoped this is not a problem as CamelContext will keep track on
> the created Producer/Consumer in its internal _servicesToClose_.
> Which is then stopped when CamelContext stops.
> For prototype we need a different strategy such as
> - proxy it to use pooled producers/consumers which CamelContext manage the
> lifecycle
> - use a shared ProducerTemplate / ConsumerTemplate instead which CamelContext
> manages the lifecycle
> - other
> - maybe some thread local tricks
