简单的mq开发

1.下载ActiveMQ

去官方网站下载:http://activemq.apache.org/

 

2.运行ActiveMQ

解压缩apache-activemq-5.5.1-bin.zip,需要mq的jar包activemq-all-5.9.0.jar

修改配置文件activeMQ.xml,将0.0.0.0修改为localhost

       

       

       

      

       

然后双击apache-activemq-5.5.1\bin\activemq.bat运行ActiveMQ程序。

1.创建class文件ConsumerTest

package on.it.mq;

import javax.jms.JMSException;

public class ConsumerTest implements Runnable {
    static Thread t1 = null;

    /**
     * @param args
     * @throws InterruptedException
     * @throws InterruptedException
     * @throws JMSException
     * @throws InterruptedException
     */
    public static void main(String[] args) throws InterruptedException {

        t1 = new Thread(new ConsumerTest());
        t1.setDaemon(false);
        t1.start();
        /**
         * 如果发生异常,则重启consumer
         */
        /*while (true) {
            System.out.println(t1.isAlive());
            if (!t1.isAlive()) {
                t1 = new Thread(new ConsumerTest());
                t1.start();
                System.out.println("重新启动");
            }
            Thread.sleep(5000);
        }*/
        // 延时500毫秒之后停止接受消息
        // Thread.sleep(500);
        // consumer.close();
    }

    public void run() {
        try {
            ConsumerTool consumer = new ConsumerTool();
            consumer.consumeMessage();
            while (ConsumerTool.isconnection) {    
            }
        } catch (Exception e) {
        }

    }
}

2.创建class文件ConsumerTool

package on.it.mq;
import javax.jms.Connection;      
import javax.jms.Destination;      
import javax.jms.ExceptionListener;
import javax.jms.JMSException;      
import javax.jms.MessageConsumer;      
import javax.jms.Session;      
import javax.jms.MessageListener;      
import javax.jms.Message;      
import javax.jms.TextMessage;      
     
import org.apache.activemq.ActiveMQConnection;      
import org.apache.activemq.ActiveMQConnectionFactory;      
     
public class ConsumerTool implements MessageListener,ExceptionListener {      
    private String user = ActiveMQConnection.DEFAULT_USER;      
    private String password = ActiveMQConnection.DEFAULT_PASSWORD;      
    private String url =ActiveMQConnection.DEFAULT_BROKER_URL;      
    private String subject = "mytopic";      
    private Destination destination = null;      
    private Connection connection = null;      
    private Session session = null;      
    private MessageConsumer consumer = null;  
    public static Boolean isconnection=false;
    // 初始化      
    private void initialize() throws JMSException, Exception {      
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(      
                user, password, url);      
        connection = connectionFactory.createConnection();      
        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);      
        destination = session.createTopic(subject);      
        consumer = session.createConsumer(destination);     
    }      
     
    // 消费消息      
    public void consumeMessage() throws JMSException, Exception {      
        initialize();      
        connection.start();
        consumer.setMessageListener(this);    
        connection.setExceptionListener(this);
        isconnection=true;
        System.out.println("Consumer:->Begin listening...");      
        // 开始监听  
        // Message message = consumer.receive();      
    }
    // 关闭连接      
    public void close() throws JMSException {      
        System.out.println("Consumer:->Closing connection");      
        if (consumer != null)      
            consumer.close();      
        if (session != null)      
            session.close();      
        if (connection != null)      
            connection.close();      
    }
    // 消息处理函数      
    public void onMessage(Message message) {      
        try {      
            if (message instanceof TextMessage) {      
                TextMessage txtMsg = (TextMessage) message;      
                String msg = txtMsg.getText();      
                System.out.println("Consumer:->Received: " + msg);      
            } else {      
                System.out.println("Consumer:->Received: " + message);      
            }      
        } catch (JMSException e) {      
            // TODO Auto-generated catch block      
            e.printStackTrace();      
        }      
    }

    public void onException(JMSException arg0) {
        isconnection=false;
    }      
}      
     


3创建class文件ProducerTest

package on.it.mq;
import java.util.Random;

import javax.jms.JMSException;      

public class ProducerTest {      
     
    /**    
     * @param args    
     */     
    public static void main(String[] args) throws JMSException, Exception {      
        ProducerTool producer = new ProducerTool();
        Random random = new Random();
        for(int i=0;i<20;i++){
            
            Thread.sleep(random.nextInt(10)*1000);
            
            producer.produceMessage("Hello, world!--"+i);      
            producer.close();
        }
        
    }      
}      


4创建class文件ProducerTool

package on.it.mq;
import javax.jms.Connection;      
import javax.jms.DeliveryMode;      
import javax.jms.Destination;      
import javax.jms.JMSException;      
import javax.jms.MessageProducer;      
import javax.jms.Session;      
import javax.jms.TextMessage;      
     
import org.apache.activemq.ActiveMQConnection;      
import org.apache.activemq.ActiveMQConnectionFactory;      
     
public class ProducerTool {        
    private String user = ActiveMQConnection.DEFAULT_USER;         
    private String password = ActiveMQConnection.DEFAULT_PASSWORD;       
    private String url = ActiveMQConnection.DEFAULT_BROKER_URL;       
    private String subject = "mytopic";      
    private Destination destination = null;      
    private Connection connection = null;      
    private Session session = null;      
    private MessageProducer producer = null;
    // 初始化      
    private void initialize() throws JMSException, Exception {      
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(      
                user, password, url);      
        connection = connectionFactory.createConnection();      
        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);      
        destination = session.createTopic(subject);      
        producer = session.createProducer(destination);      
        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);      
    }
    // 发送消息      
    public void produceMessage(String message) throws JMSException, Exception {      
        initialize();      
        TextMessage msg = session.createTextMessage(message);      
        connection.start();      
        System.out.println("Producer:->Sending message: " + message);      
        producer.send(msg);      
        System.out.println("Producer:->Message sent complete!");      
    }
    // 关闭连接      
    public void close() throws JMSException {      
        System.out.println("Producer:->Closing connection");      
        if (producer != null)      
            producer.close();      
        if (session != null)      
            session.close();      
        if (connection != null)      
            connection.close();      
    }      
}
