使用spring和activemq的XA事务

Question

I am trying to prove I don't need the activemq rar deployed to JBoss EAP 6.3 in order to use XA transactions...I'd like to use just the active mq client jar. I created a simple spring-boot project and exposed a method which gets exposed via a restful web service. The following code correctly rolls back if I have the active-mq rar deployed.

@Transactional
public void work() throws Exception {

    ConnectionFactory connectionFactory = (ConnectionFactory) this.context
            .getBean("jmsConnectionFactory");

    // Send a message
    MessageCreator messageCreator = new MessageCreator() {
        @Override
        public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage("Test message!");
        }
    };

    JmsTemplate jmsTemplate = new JmsTemplate(connectionFactory);
    System.out.println("Sending a new message.");
    jmsTemplate.send("test-destination", messageCreator);

    throw new Exception("Something bad happened!!");
}

However, when I create my own ConnectionFactory via JNDI, the code doesn't rollback and the message still gets sent.

@Transactional
public void work() throws Exception {

    ConnectionFactory connectionFactory = null;
    try {
        Context ctx = new InitialContext();
        connectionFactory = (ConnectionFactory) ctx.lookup("java:/ConnectionFactory");
    } catch (NamingException e) {
        e.printStackTrace();
        throw new RuntimeException(e);
    }

    // Send a message
    MessageCreator messageCreator = new MessageCreator() {
        @Override
        public Message createMessage(Session session) throws JMSException {
            return session.createTextMessage("Test message!");
        }
    };

    JmsTemplate jmsTemplate = new JmsTemplate(connectionFactory);
    System.out.println("Sending a new message.");
    jmsTemplate.send("test-destination", messageCreator);

    throw new Exception("Something bad happened!!");
}

What I'd like to understand is what spring-boot is doing at boot time to provide XA support when the activemq rar is deployed as a resource adaptor on EAP. If I understand that, I think I should be able to just package the active-mq client jar and my database jar in my spring app (not spring-boot based) and still provide XA support ie get spring to manage the XA transactions by delegating to the PlatformTransactionManager.

Any help would be appreciated.

Thanks, Will

Spring Boot is all about conventions. You need to indicate Spring Boot that you are connecting to a XA connection factory. According to Spring Boot documentation ( 32.3 Using a Java EE managed transaction manager ) :

Spring Boot will attempt to auto-configure JMS by looking for a ConnectionFactory at the JNDI path java:/JmsXA or java:/XAConnectionFactory
