Creating temporary JMS jms topic in Spring

Question

I\'m trying to refactor some legacy code to use Spring to handle the jms connections to a mainframe service. I need to connect create a temporary topic for the mainframe ser

Answer 1

I was able to create a queue dynamically using the following code in a Spring Boot app:

In Application.java

@Bean 
public ConnectionFactory jmsFactory()
{
    ActiveMQConnectionFactory amq = new ActiveMQConnectionFactory()

    amq.setBrokerURL("tcp://somehost");

    return amq;
}

@Bean 
public JmsTemplate myJmsTemplate()
{
    JmsTemplate jmsTemplate = new JmsTemplate(jmsFactory());

    jmsTemplate.setPubSubDomain(false);
    return jmsTemplate;
}

Then in another class which creates the queue dynamically:

@Component
public class Foo {
    @Autowired
    private ConnectionFactory jmsFactory;

    public void someMethod () {
        DefaultMessageListenerContainer messageListener = new DefaultMessageListenerContainer();

        messageListener.setDestinationName("queueName");
        messageListener.setConnectionFactory(jmsFactory);
        messageListener.setMessageListener(new Consumer("queueName"));
        messageListener.setPubSubDomain(false);
        messageListener.initialize();
        messageListener.start();
    }
}
