ActiveMQ使用setMessageListener监听器小demo

消息生产者

/**

public class JmsProduce {

    public static final  String ACTIVEMQ_URL = "tcp://192.168.78.131:61616";
    public static final  String QUEUE_NAME= "queue01";


    public static void main(String[] args) throws Exception{
        //1.创建工厂,安装url地址采用默认账户密码
        ActiveMQConnectionFactory activeMQConnectionFactory  = new ActiveMQConnectionFactory(ACTIVEMQ_URL);

        //2.通过连接工厂,获得连接Connection
        Connection connection = activeMQConnectionFactory.createConnection();
        //启动
        connection.start();

        //3.创建会话session (有两个参数,1.事物 2.签收)
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        //4.创建目的地(具体是队列还是主题)
         Queue queue = session.createQueue(QUEUE_NAME);

         //5.创建消息生产者
         MessageProducer messageProducer = session.createProducer(queue);
         //6.通过使用messageProducer生产3条消息发送到MQ队列中
         for(int  q= 1;q<=50;q++){

             //7.创建消息
             TextMessage textMessage = session.createTextMessage("msg----"+q);//理解为一个字符串
             //8.通过消息生产者发布消息
             messageProducer.send(textMessage);
         }

         //9.关闭资源
         messageProducer.close();
         session.close();
         connection.close();

        System.out.println("消息发送成功!");
    }
}

消息消费者

/**
 * @author songzixian
 * @description ActiveMQ消费者
 */
public class JmsConsumer {

    public static final String ActiveMQ_URL="tcp://192.168.78.131:61616";
    public static final String QUEUE_NAME = "queue01";

    public static void main(String[] args) throws Exception{
        //1.创建连接工厂,按照指定的url地址,采用默认帐号密码
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(ActiveMQ_URL);

        //2.通过连接工厂,获得连接connection
        Connection connection = activeMQConnectionFactory.createConnection();
        //启动
        connection.start();
        //3.创建会话session
        Session session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);

        //4.创建目的地(具体是列队还是主题topic);
        Queue queue = session.createQueue(QUEUE_NAME);


        //5.创建消息消费者
        MessageConsumer messageConsumer = session.createConsumer(queue);

        //使用监听器,有消息就处理没消息就关掉
        messageConsumer.setMessageListener(new MessageListener() {
            @Override
            public void onMessage(Message message) {
                //如果列队消息不等于空,则执行
                if(null != message && message instanceof TextMessage){
                    TextMessage textMessage = (TextMessage) message;
                    try {
                        System.out.println("消费者接收到了消息"+textMessage.getText());
                    } catch (JMSException e) {
                        e.printStackTrace();
                    }
                }
            }
        });
        //保持控制台不关闭
        System.in.read();


        //关闭资源
        messageConsumer.close();
        session.close();
        connection.close();
    }
}
