ActiveMQ使用例子

网上收集的例子：有broker，producer，consumer

public class MqApp {
    public static void main(String[] args) throws Exception {
        // 启动broker
        BrokerService broker = new BrokerService();
        // configure the broker
        broker.addConnector("tcp://localhost:61616");
        broker.start();

        // 创建producer和consumer
        makeThread(new HelloProducer(), false);
        makeThread(new HelloConsumer(), false);

//        LockSupport.park();
    }

    public static void makeThread(Runnable runnable, boolean daemon) {
        Thread t = new Thread(runnable);
        t.setDaemon(daemon);
        t.start();
    }

    public static class HelloProducer implements Runnable {
        public void run() {
            try {
                // Create a ConnectionFactory
                ActiveMQConnectionFactory connectionFactory =
//                        new ActiveMQConnectionFactory("vm://localhost");
                        new ActiveMQConnectionFactory("tcp://localhost:61616");

                // Create a Connection
                Connection connection = connectionFactory.createConnection();
                connection.start();

                // Create a Session
                Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

                // Create the destination (Topic or Queue)
                Destination destination = session.createQueue("TEST.FOO");

                // Create a MessageProducer from the Session to the Topic or Queue
                MessageProducer producer = session.createProducer(destination);
                producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
