How to configure connection factor for Camel SJMS2 Component - apache-camel

Question

I'm confused about the best way to configure the SJMS2 component. I'm using camel-spring-boot-starter in a simple test application and trying to write from a ProducerTemplate to ActiveMQ Artemis using the SJMS2 Camel Component. The component documentation says it handles things like connection caching and such which I would normally configure in my ConnectionFactory bean, so I'm getting the sense that I should defining less in my Configuration than I would without using Camel.
The documentation seems to lack a clear example of how to configure an jsms2 route and its ConnectionFactory when using Camel Spring. Is there a good example of this somewhere or could someone show me how that would look? Here's my current test application:
Spring Boot Application:
#SpringBootApplication
public class WebhookpublisherApplication implements CommandLineRunner {
#Autowired
private ProducerTemplate producerTemplate;
public static void main(String[] args) {
SpringApplication.run(WebhookpublisherApplication.class, args);
}
#Override
public void run(String... args) throws Exception {
producerTemplate.sendBody("direct:test", "testBody");
}
}
Route:
#Component
public class RestToJmsRoute extends RouteBuilder {
#Override
public void configure() {
from("direct:test")
.log("Recieved a test body: ${body}")
.to("sjms2:topic:test-topic");
}
}
JMS Config (which is clearly not being used by the Camel component)
#Configuration
public class JmsConfig {
#Bean
public ActiveMQConnectionFactory activeMQConnectionFactory() {
return new ActiveMQConnectionFactory("tcp://localhost:61616");
}
}

The above is resulting in the following exception:
Caused by: java.lang.IllegalArgumentException: ConnectionResource or
ConnectionFactory must be configured for sjms2://test-topic

Answer 1

I ended up adding the following configuration class:
#Configuration
public class CamelContextConfig {
#Bean
public CamelContextConfiguration contextConfiguration() {
return new CamelContextConfiguration() {
#Override
public void beforeApplicationStart(CamelContext context) {
Sjms2Component component = new Sjms2Component();
ActiveMQConnectionFactory activeMqConnectionFactory = new ActiveMQConnectionFactory("tcp://myArtemisHost:61616");
activeMqConnectionFactory.setUser("user");
activeMqConnectionFactory.setPassword("pass");
component.setConnectionFactory(activeMqConnectionFactory);
context.addComponent("sjms2", component);
}
#Override
public void afterApplicationStart(CamelContext camelContext) {
}
};
}
}
and then I changed my pom dependencies to these:

<version>2.3.0.RELEASE</version>
