Franky Georg commented on CAMEL-15686:
--------------------------------------
I've added an usage example in the description.
I'm actually struggling to replicate this now - my example above is working
perfectly at home with Camel 3.3, 3.4.4, and 3.5.
I'll take another look at my failing code when I'm back in the office, but that
won't be for a couple days.
> Enable EndpointDSL with simple expressions within an Endpoint Builder bean
> --------------------------------------------------------------------------

> Key: CAMEL-15686
> URL: https://issues.apache.org/jira/browse/CAMEL-15686
> Project: Camel
> Issue Type: Improvement
> Components: camel-endpointdsl
> Environment: Experienced with
> * Camel 3.3
> * Spring Boot 2.3.4
> Reporter: Franky Georg
> Assignee: Claus Ibsen
> Priority: Minor
>
> Injecting an EndpointProducerBuilder bean that uses a simple expression
> causes an exception.
> {code:java}
> @Autowired
> @Qualifier("publishToKafkaEndpoint")
> EndpointProducerBuilder publishToKafkaEndpoint;
> @Bean
> org.apache.camel.builder.EndpointProducerBuilder publishToKafkaEndpoint() {
> return kafka("${exchangeProperty.destination}");
> }
> @Override
> public void configure() {
> from("direct:publish-to-kafka")
> .toD(publishToKafkaEndpoint)
> ;
> }{code}
> Exception from org.apache.kafka.clients.Metadata:
> {code:java}
> Metadata response reported invalid topics
> [${exchangeProperty.destination}]{code}
>
> It _does_ work for static endpoints:
> {code:java}
> return kafka("myTopic"); // This works fine from an
> EndpointProducerBuilder bean{code}
> And it _does_ work for dynamic endpoints in URI form:
> {code:java}
> return "kafka:${exchangeProperty.destination}"; // This works fine but
> you lose type safety{code}
>
> Creating beans like this is useful for unit testing as they can be overridden
> to return mock/direct/whatever-is-useful, _without_ _first creating the
> original endpoint_, which can significantly reduce execution time.
