ActiveMQ生產者和消費者案例

一、啓動ActiveMQ

 

二、生產者代碼 

/**
 * @program: activemqdemo
 * @description:
 * @author: hq.zheng
 * @create: 2019-08-17 14:45
 */
public class Producer {

    public static void main(String[] args) throws JMSException {
        // ConnectionFactory ：連接工廠，JMS 用它創建連接
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER,
                ActiveMQConnection.DEFAULT_PASSWORD, "tcp://127.0.0.1:61616");

        //JMS 客戶端到JMS Provider 的連接
        Connection connection = connectionFactory.createConnection();
        //啓動連接
        connection.start();

        //Session： 一個發送或接收消息的線程,自動簽收
        Session session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
        //Destination ：消息的目的地;消息發送給誰.
        //獲取session注意參數值my-queue是Query的名字
        Destination destination = session.createQueue("my-queue");
        //MessageProducer：消息生產者
        MessageProducer producer = session.createProducer(destination);
        //設置不持久化
        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

        // 發送一條消息
        TextMessage textMessage = session.createTextMessage("This is my first ActiveMQ");
        producer.send(textMessage);

        //關閉連接
        session.close();
        connection.close();
    }

}

運行後

 

三、消費者代碼 

/**
 * @program: activemqdemo
 * @description:
 * @author: hq.zheng
 * @create: 2019-08-17 15:08
 */
public class Receiver {
    public static void main(String[] args) throws JMSException {
        // ConnectionFactory ：連接工廠，JMS 用它創建連接
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER,
                ActiveMQConnection.DEFAULT_PASSWORD, "tcp://127.0.0.1:61616");
        // JMS 客戶端到JMS Provider 的連接
        Connection connection = connectionFactory.createConnection();
        connection.start();
        // Session： 一個發送或接收消息的線程
        Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
        // Destination ：消息的目的地;消息發送給誰.
        // 獲取session注意參數值xingbo.xu-queue是一個服務器的queue，須在在ActiveMq的console配置
        Destination destination = session.createQueue("my-queue");
        // 消費者，消息接收者
        MessageConsumer consumer = session.createConsumer(destination);
        while (true) {
            TextMessage message = (TextMessage) consumer.receive();
            if (null != message) {
                System.out.println("收到消息：" + message.getText());
                session.commit();
            } else
                break;
        }
        session.close();
        connection.close();

    }
}
