1.下载安装ActiveMQ
官网下载地址：http://activemq.apache.org/download.html
ActiveMQ 提供了Windows 和Linux、Unix 等几个版本，我选择了Windows 版本下进行开发。
下载完压缩包后，直接解压：
目录：
bin存放的是脚本文件
conf存放的是基本配置文件
data存放的是日志文件
docs存放的是说明文档
examples存放的是简单的实例
lib存放的是activemq所需jar包
webapps用于存放项目的目录
2.启动ActiveMQ
可以在命令行中用命令启动，我这里就直接鼠标点击运行脚本启动了
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。
admin：http://127.0.0.1:8161/admin/
我们在浏览器打开链接之后输入账号密码（默认账号密码都是admin），类似于访问tomcat。
登陆成功后页面显示：
ActiveMQ启动就完成了，关闭直接点击关闭脚本或用命令管就可以了。
3.不多bb，直接上helloworld代码
创建一个maven项目，最好是用jdk1.8，我用jdk1.7会报错，pom.xml依赖如下：
<dependencies> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-all</artifactId> <version>5.15.0</version> </dependency> </dependencies>
3.1创建生产者类：
package com.iflytek; 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; /** * * @author cjf * 生产者 */ 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<>(); 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); //消息生产者 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 (JMSException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } } }
3.2，创建消费者类：
package com.iflytek; 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; /** * * @author cjf * 消费者 */ public class Comsumer { private static final String USERNAME = ActiveMQConnection.DEFAULT_USER; private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD; private static final String BROKEN_URL = ActiveMQConnection.DEFAULT_BROKER_URL; ConnectionFactory connectionFactory; Connection connection; Session session; ThreadLocal<MessageConsumer> threadLocal = new ThreadLocal<>(); AtomicInteger count = new AtomicInteger(); public void init(){ try { connectionFactory = new ActiveMQConnectionFactory(USERNAME,PASSWORD,BROKEN_URL); connection = connectionFactory.createConnection(); 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 (JMSException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } } }
4.运行ActiveMQ项目，进行测试
4.1，生产者生产消息：
package com.iflytek; /** * * @author cjf * 测试生产者生产消息 */ public class TestProducter { public static void main(String[] args){ Producter producter = new Producter(); producter.init(); TestProducter testMq = new TestProducter(); try { Thread.sleep(1000); } catch (InterruptedException 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(); } } } } }
运行结果：
4.2，测试消费者消费消息：
package com.iflytek; /** * * @author cjf * activeMQ测试消费者消费消息 */ public class TestConsumer { public static void main(String[] args){ Comsumer comsumer = new Comsumer(); comsumer.init(); TestConsumer testConsumer = new TestConsumer(); new Thread(testConsumer.new ConsumerMq(comsumer)).start(); new Thread(testConsumer.new ConsumerMq(comsumer)).start(); new Thread(testConsumer.new ConsumerMq(comsumer)).start(); new Thread(testConsumer.new ConsumerMq(comsumer)).start(); } private class ConsumerMq implements Runnable{ Comsumer comsumer; public ConsumerMq(Comsumer comsumer){ this.comsumer = comsumer; } @Override public void run() { while(true){ try { comsumer.getMessage("Jaycekon-MQ"); Thread.sleep(10000); } catch (InterruptedException e) { e.printStackTrace(); } } } } }
运行结果：
5.ActiveMQ的helloworld就写完了，更多MQ其他的知识自己再好好学，我也是个菜鸡刚看了2天这东西，求关注啊，可以交流一下。
