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;

AtomicInteger count = new AtomicInteger(0);
// 链接工厂

// 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 {

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.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();
}
}
}
}
}
执行结果如下:
