ActiveMQ

参考：http://yufenfei.iteye.com/blog/1874089      dome::http://blog.youkuaiyun.com/jiuqiyuliang/article/details/48608237

1>ActiveMq的下载

　　http://activemq.apache.org/activemq-5144-release.html

2>ActiveMq的安装

　　解压任意目录下即可

3>启动ActiveMq服务器

　　直接运行bin\activemq.bat

4>测试

　　在cmd命令行执行： netstat -an|find"61616"

　　C:\>netstat -an|find "61616"

      TCP        0.0.0.0:61616                    0.0.0.0:0                            LISTENING

5>监控

　　ActiveMQ默认启动时，启动了内置的jetty服务器，提供一个用于监控ActiveMQ的admin应用

　　Url:  http://127.0.0.1:8161/admin   需要输入登录用户名与密码；默认用户名与密码是 admin,admin

　　注意：

   （1）、登录的用户与密码配置

           conf/jetty-realm.properties

   （2）、8161端口配置

           conf/jetty.xml

6>点对点Dome

　（1）先将activemq-all-5.14.4.jar 引入工程的lib目录下

　（2）消息生产者

package com.wyx.test;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;

import org.apache.activemq.ActiveMQConnectionFactory;

public class JmsProducer {
    //默认连接用户名
    private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;
    //默认连接密码
    private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;
    //默认连接URL
    private static final String BROKEURL = ActiveMQConnection.DEFAULT_BROKER_URL;
    //发送消息的数量
    private static final int SENDNUM = 10;
    public static void main(String[] args){
        //连接工厂
        ConnectionFactory  connectionFactory;
        //连接
        Connection connection = null;
        //Session会话 接收或者发送消息的线程
        Session session;
        //消息目的地（Queue）
        Destination destination;
        //消息生产者
        MessageProducer messageProducer;
        //实例化连接工厂
        connectionFactory = new ActiveMQConnectionFactory(JmsProducer.USERNAME,JmsProducer.PASSWORD,JmsProducer.BROKEURL);
        try {
            //通过连接工厂获取连接
            connection = connectionFactory.createConnection();
            //启动链接
            connection.start();
            //创建Session
            session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
            //创建一个"helloWorld"的Queue
            destination = session.createQueue("HelloWorld");
            //创建消息生产者
            messageProducer = session.createProducer(destination);
            //发送消息
            sendMessage(session,messageProducer);
            //消息确认
            session.commit();            
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }finally{
            if(connection != null){
                try {
                    connection.close();
                } catch (JMSException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }
    
    public static void sendMessage(Session session,MessageProducer messageProducer) throws Exception{
        for(int i=0;i<JmsProducer.SENDNUM;i++){
            //创建一条文本消息
            TextMessage message = session.createTextMessage("ActiveMq 发送消息=>"+ i);
            System.out.println("发送消息---"+i);
            messageProducer.send(message);
        }
    }
}

　（3）消息消费者

package com.wyx.test;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.swing.plaf.synth.SynthSeparatorUI;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

public class JmsConsumer {
    //默认连接名
    private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;
    //默认连接密码
    private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;
    //默认连接URL
    private static final String BROKEURL = ActiveMQConnection.DEFAULT_BROKER_URL;
    public static void main(String[] args){
        ConnectionFactory connectionFactory;
        Connection connection = null;
        Session session;
        Destination destination;
        MessageConsumer messageConsumer;
        connectionFactory = new ActiveMQConnectionFactory(JmsConsumer.USERNAME,JmsConsumer.PASSWORD,JmsConsumer.BROKEURL);
        try {
            connection = connectionFactory.createConnection();
            connection.start();
            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
            destination = session.createQueue("HelloWorld");
            messageConsumer = session.createConsumer(destination);
            while(true){
                TextMessage textMessage = (TextMessage)messageConsumer.receive(100000);
                if(textMessage != null){
                    System.out.println("接收消息---"+textMessage.getText());
                }else{
                    break;
                }
            }
            //确认消息
            session.commit();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}
