Spring - Create Bean after Camel Context is started

Hello everybody,

using camel 2.20 with spring 5.0.1 and need to start another component (defined as spring bean) after camel context has started. I added 'depends-on="camelContextId"' to the other beans spring xml definition, but this has a no effect as the camel context is starting asynchronously.

Any ideas how to solve this?

Thanks and kind regards,

Pascal

Could you add some endpoint like direct (failIfNoConsumers=false), vm, seda or activmq beween the routes that want to sent to your component and the route that consumes your component?

Consuming Endpoints                                                                                         Your Component Endpoint
| ----------------------------------------------------------------------------------------------|

=>
Consuming Endpoints                            (direct,vm,seda,activemq)                 Your Component Endpoint
|-------------------------------------------------|---------------------------------------------|
             Static route                                            dynamic route

Then the message may stay in that endpoint until a consumer will register on the endpoint.

Aw: AW: Spring - Create Bean after Camel Context is started

Posted by Pascal Schumacher <Pa...@gmx.net>.

Hi Michael,

thanks for the response.

Sorry for not making myself clear. The other component accesses multiple camel routes and throws errors if the routes are not started yet, therefore I would like spring to start it after the camel context has been started. The simplifed spring configuration:

<beans>
    <camelContext id="camelContext" />
    <bean id="componentDependingOnStartedCamelContext" depends-on="camelContext" />
</beans>
 
Cheers,
Pascal

Hi Pascal,

perhaps you can encapsulate the call to the bean into a single route builder and add that route dynamically to the Camel Context like here:
https://stackoverflow.com/questions/10451444/add-camel-route-at-runtime-in-java

But I'm not sure if I understood the use case correctly.

Hi Pascal, 

perhaps you can encapsulate the call to the bean into a single route builder and add that route dynamically to the Camel Context like here:
https://stackoverflow.com/questions/10451444/add-camel-route-at-runtime-in-java

But I'm not sure if I understood the use case correctly.

Hi Pascal,
I think you'll find StartupListener[1] helpful, there is a
`addStartupListener` method on the CamelContext,
