Morning all,
I've been struggling lately with the spring-boot-artemis-starter. My understanding of its spring-boot support was the following:
spring.artemis.mode=embedded
and, like tomcat, spring-boot will instanciate a broker reachable through tcp (server mode). The following command should be successful: nc -zv localhost 61616
spring.artmis.mode=native
and spring-boot will only configure the jms template according to the spring.artemis.*
properties (client mode).The client mode works just fine with a standalone artemis server on my machine. Unfortunatelly, I could never manage to reach the tcp port in server mode.
I would be grateful if somebody confirms my understanding of the embedded mode.
Thank you for tour help
After some digging I noted that the implementation provided out of the box by the spring-boot-starter-artemis uses org.apache.activemq.artemis.core.remoting.impl.invm.InVMAcceptorFactory
acceptor. I'm wondering if that's not the root cause (again I'm by no means an expert).
But it appears that there is a way to customize artemis configuration.
Therefore I tried the following configuration without any luck:
@SpringBootApplication
public class MyBroker {
public static void main(String[] args) throws Exception {
SpringApplication.run(MyBroker.class, args);
}
@Autowired
private ArtemisProperties artemisProperties;
@Bean
public ArtemisConfigurationCustomizer artemisConfigurationCustomizer() {
return configuration -> {
try {
configuration.addAcceptorConfiguration("netty", "tcp://localhost:" + artemisProperties.getPort());
} catch (Exception e) {
throw new RuntimeException("Failed to add netty transport acceptor to artemis instance");
}
};
}
}
You just have to add a Connector and an Acceptor to your Artemis Configuration. With Spring Boot Artemis starter Spring creates a Configuration bean which will be used for EmbeddedJMS configuration. You can see this in ArtemisEmbeddedConfigurationFactory class where an InVMAcceptorFactory
will be set for the configuration. You can edit this bean and change Artemis behaviour through custom ArtemisConfigurationCustomizer
bean which will be sucked up by Spring autoconfig and be applied to the Configuration.
An example config class for your Spring Boot application:
import org.apache.activemq.artemis.api.core.TransportConfiguration;
import org.apache.activemq.artemis.core.remoting.impl.netty.NettyAcceptorFactory;
import org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory;
import org.springframework.boot.autoconfigure.jms.artemis.ArtemisConfigurationCustomizer;
import org.springframework.context.annotation.Configuration;
@Configuration
public class ArtemisConfig implements ArtemisConfigurationCustomizer {
@Override
public void customize(org.apache.activemq.artemis.core.config.Configuration configuration) {
configuration.addConnectorConfiguration("nettyConnector", new TransportConfiguration(NettyConnectorFactory.class.getName()));
configuration.addAcceptorConfiguration(new TransportConfiguration(NettyAcceptorFactory.class.getName()));
}
}
