ActiveMQ入门教程

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

启动ActiveMQ以后，登陆：http://localhost:8161/admin/。

3.创建Eclipse项目并运行

Producter类

package com.hbk.test;import java.util.concurrent.atomic.AtomicInteger;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.JMSException;import javax.jms.MessageProducer;import javax.jms.Queue;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;public class Producter {    // ActiveMq 的默认用户名    private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;    // ActiveMq 的默认登录密码    private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;    // ActiveMQ 的链接地址    private static final String BROKEN_URL = ActiveMQConnection.DEFAULT_BROKER_URL;    AtomicInteger count = new AtomicInteger(0);    // 链接工厂    ConnectionFactory connectionFactory;    // 链接对象    Connection connection;    // 事务管理    Session session;    ThreadLocal<MessageProducer> threadLocal = new ThreadLocal<MessageProducer>();    public void init() {        try {            // 创建一个链接工厂            connectionFactory = new ActiveMQConnectionFactory(USERNAME, PASSWORD, BROKEN_URL);            // 从工厂中创建一个链接            connection = connectionFactory.createConnection();            // 开启链接            connection.start();            // 创建一个事务（这里通过参数可以设置事务的级别）            session = connection.createSession(true, Session.SESSION_TRANSACTED);        } catch (JMSException e) {            e.printStackTrace();        }    }    public void sendMessage(String disname) {        try {            // 创建一个消息队列            Queue queue = session.createQueue(disname);            // 消息生成者            MessageProducer messageProducer = null;            if (threadLocal.get() != null) {                messageProducer = threadLocal.get();            } else {                messageProducer = session.createProducer(queue);                threadLocal.set(messageProducer);            }            while (true) {                Thread.sleep(1000);                int num = count.getAndIncrement();                // 创建一条消息                TextMessage msg = session.createTextMessage(Thread.currentThread().getName() + "productor:我是大帅哥，我现在正在生产东西！,count:" + num);                System.out.println(Thread.currentThread().getName() + "productor:我是大帅哥，我现在正在生产东西！,count:" + num);                // 发送消息                messageProducer.send(msg);                // 提交事务                session.commit();            }        } catch (Exception e) {            e.printStackTrace();        }    }}

Consumer类

package com.hbk.test;import java.util.concurrent.atomic.AtomicInteger;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.JMSException;import javax.jms.MessageConsumer;import javax.jms.Queue;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;public class Consumer {    // ActiveMq 的默认用户名    private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;    // ActiveMq 的默认登录密码    private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;    // ActiveMQ 的链接地址    private static final String BROKEN_URL = ActiveMQConnection.DEFAULT_BROKER_URL;    AtomicInteger count = new AtomicInteger(0);    // 链接工厂    ConnectionFactory connectionFactory;    // 链接对象    Connection connection;    // 事务管理    Session session;    ThreadLocal<MessageConsumer> threadLocal = new ThreadLocal<MessageConsumer>();    public void init() {        try {            // 创建一个链接工厂            connectionFactory = new ActiveMQConnectionFactory(USERNAME, PASSWORD, BROKEN_URL);            // 从工厂中创建一个链接            connection = connectionFactory.createConnection();            // 开启链接            connection.start();            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);        } catch (JMSException e) {            e.printStackTrace();        }    }    public void getMessage(String disname) {        try {            Queue queue = session.createQueue(disname);            MessageConsumer consumer = null;            if (threadLocal.get() != null) {                consumer = threadLocal.get();            } else {                consumer = session.createConsumer(queue);                threadLocal.set(consumer);            }            while (true) {                Thread.sleep(1000);                TextMessage msg = (TextMessage) consumer.receive();                if (msg != null) {                    msg.acknowledge();                    System.out.println(Thread.currentThread().getName() + ": Consumer:我是消费者，我正在消费Msg" + msg.getText() + "--->" + count.getAndIncrement());                } else {                    break;                }            }        } catch (Exception e) {            e.printStackTrace();        }    }}

测试生产者生产消息

package com.hbk.test;public class TestProcucter {    public static void main(String[] args) {        Producter producter = new Producter();        producter.init();        TestProcucter testMQ = new TestProcucter();        try {            Thread.sleep(1000);        } catch (Exception e) {            e.printStackTrace();        }        // Thread 1        new Thread(testMQ.new ProductorMq(producter)).start();        // Thread 2        new Thread(testMQ.new ProductorMq(producter)).start();        // Thread 3        new Thread(testMQ.new ProductorMq(producter)).start();        // Thread 4        new Thread(testMQ.new ProductorMq(producter)).start();        // Thread 5        new Thread(testMQ.new ProductorMq(producter)).start();    }    private class ProductorMq implements Runnable {        Producter producter;        public ProductorMq(Producter producter) {            this.producter = producter;        }        @Override        public void run() {            while (true) {                try {                    producter.sendMessage("Jaycekon-MQ");                    Thread.sleep(10000);                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }    }}
