ArtemisMQ is successor of ActiveMQ, using it with springboot is easy as auto-configuration is provided by spring-boot-starter-artemis. A starter project is created here. Below are some notes in using the starter project.

1. Artemis mode in Springboot config

There are 2 modes for the configuration spring.artemis.mode:

• embedded
  Server mode, embed Artemis Server into the springboot app. Note: By default embedded server only accept internal connection. See point 2 to allow external connection.
• native
  Client mode, no Artemis Server included. A JmsTemplate will be auto-configured for connecting to the Artemis Server specified by host & port properties.
  

  spring:
      artemis:
        mode: native  # client mode
        host: localhost
        port: 61616

2. Allow embedded Artemis server to receive external connection

By default embedded Artemis won’t accept external connection. To allow this, edit springboot default config with below code.

@Configuration
public class ArtemisConfig implements ArtemisConfigurationCustomizer {
    @Override
    public void customize(org.apache.activemq.artemis.core.config.Configuration configuration) {
        // Allow Artemis to accept tcp connections (Default port localhost:61616)
        configuration.addConnectorConfiguration("nettyConnector", new TransportConfiguration(NettyConnectorFactory.class.getName()));
        configuration.addAcceptorConfiguration(new TransportConfiguration(NettyAcceptorFactory.class.getName()));
    }
}

3. Artemis auto destination creation feature

There is no need to define destinations (e.g. queue) in Artemis Server as destination are auto created when first use (e.g. incoming message).
