activeMq 簡單的通信程序

首先是發送方：程序代碼如下！

package JMStile;

 

import java.io.BufferedReader;

import java.io.InputStreamReader;

import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.MessageProducer;

import javax.jms.Queue;

import javax.jms.Session;

import javax.jms.TextMessage;

import javax.jms.Topic;

import javax.jms.TopicConnection;

import javax.naming.InitialContext;

import javax.jms.Destination;

 

import org.apache.activemq.ActiveMQConnectionFactory;

/*

 * 

 * 消息的發送方

 * 

 * **/

 

public class Sender {

 

 public void send(){

 

try {

ConnectionFactory connectionFactory=new ActiveMQConnectionFactory(ActiveMQConnectionFactory.DEFAULT_USER,

     ActiveMQConnectionFactory.DEFAULT_PASSWORD,"tcp://192.168.16.228:61616");

TopicConnection  connection=(TopicConnection)connectionFactory.createConnection();

//創建session

Session session=connection.createSession(true, Session.AUTO_ACKNOWLEDGE);

//設置將消息發送給誰

 Destination destination=session.createQueue("my-queue");

 MessageProducer sender=session.createProducer(destination);

 

TextMessage messagetext=session.createTextMessage("我的第一個MQ發送成功了！！！！！！"+destination);

System.out.println("消息的值："+messagetext.getText());

sender.send(messagetext);

session.commit();

            connection.close();

            System.out.println("發送完畢！!");

} catch (Exception e) {

e.printStackTrace();

System.exit(1);//終止真在運行的JVM，非0的代表異常終止虛擬機

}

 }

public static void main(String[] args) {

// TODO Auto-generated method stub

      new Sender().send();

}

 

}

下面的是接受方的代碼：

package JMStile;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.Destination;

import javax.jms.JMSException;

import javax.jms.Message;

import javax.jms.MessageConsumer;

import javax.jms.MessageListener;

import javax.jms.Queue;

import javax.jms.Session;

import javax.jms.TextMessage;

import javax.jms.Topic;

import javax.jms.TopicConnection;

import javax.naming.InitialContext;

import org.apache.activemq.ActiveMQConnection;

import org.apache.activemq.ActiveMQConnectionFactory;

/*

 * 

 * 消息的接收方

 * 

 * **/

public class Receiver {

    private boolean stop=false;

    

public void receive(){

try {

            //創建連接

ConnectionFactory factory=new ActiveMQConnectionFactory(ActiveMQConnectionFactory.DEFAULT_USER,

ActiveMQConnectionFactory.DEFAULT_PASSWORD,"tcp://192.168.16.228:61616");

//JMS 客戶端到JMS Provider 的連接 

TopicConnection connection=(TopicConnection)factory.createConnection();

//創建session,一個接受或發送消息的線程

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

//指定消息的目的地

   Destination destination=session.createQueue("my-queue");

//消費者，消息的接收者

MessageConsumer receiver=session.createConsumer(destination);

connection.start();

while(true){

TextMessage msgMessage=(TextMessage)receiver.receive(1000);

System.out.println("接收："+msgMessage);

if(msgMessage!=null){

//打印一下消息

System.out.println("收到消息：-------》"+msgMessage.getText());

}else {

break;

}

}

            connection.close();

            session.close();

            System.out.println("接收完畢!");

} catch (Exception e) {

e.printStackTrace();

System.exit(1);

}

}

    public static void main(String[] args) {

new Receiver().receive();

}

}

運行程序：

首先運行一下發送方程序，然後運行接受方，看能能不能接受到消息。能接受到消息說明通信成功！
