【分布式系列之ActiveMq】ActiveMq入门示例
前言
github地址：https://github.com/AndyFlower/web-back/tree/master/ActiveMq01
下载ActiveMQ :http://activemq.apache.org/download.html
放到自己的目录，大致目录如下：
- 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
然后启动ActiveMQ:比如我的目录是：D:\develop tools\apache-activemq-5.15.2\bin\win64下的activemq.bat
出现如下消息则说明启动成功了。
登录上述启动成功的地址：http://127.0.0.1:8161用户名和密码是admin:admin
一、创建一个java项目，加入maven依赖
<dependencies>
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-all</artifactId>
<version>5.15.2</version>
</dependency>
</dependencies>
二、项目目录如下
三、编写具体的生产者和消费者
package com.slp.activemq;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
import javax.jms.*;
import java.util.concurrent.atomic.AtomicInteger;
/**
* @author sanglp
* @create 2017-12-05 11:30
* @desc 生产者
**/
public class Producer {
//ActiveMQ默认用户名
private static final String USERNAME= ActiveMQConnection.DEFAULT_USER;
//ActiveMQ默认登陆密码
private static final String PASSWORD= ActiveMQConnection.DEFAULT_PASSWORD;
//ActiveMQ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（通过参数设置事务的级别）
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:我正在生产东西！，count:"+count);
System.out.println(Thread.currentThread().getName()+"productor：我正在生产东西！，count:"+count);
//发送消息
messageProducer.send(msg);
//提交事务
session.commit();
}
} catch (JMSException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
package com.slp.activemq;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
import javax.jms.*;
import java.util.concurrent.atomic.AtomicInteger;
/**
* @author sanglp
* @create 2017-12-05 11:30
* @desc 消费者
**/
public class Consumer {
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<MessageConsumer>();
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 ;
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();
}
}
}
四、运行测试
package com.slp.activemq;
/**
* @author sanglp
* @create 2017-12-05 11:31
* @desc mq测试
**/
public class TestMq {
public static void main(String[] args){
Producer producer = new Producer();
producer.init();
TestMq testMq = new TestMq();
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
//Thread 1
new Thread(testMq.new ProducorMq(producer)).start();
//Thread 2
new Thread(testMq.new ProducorMq(producer)).start();
//Thread 3
new Thread(testMq.new ProducorMq(producer)).start();
//Thread 4
new Thread(testMq.new ProducorMq(producer)).start();
//Thread 5
new Thread(testMq.new ProducorMq(producer)).start();
}
private class ProducorMq implements Runnable{
Producer producer;
public ProducorMq(Producer producer){
this.producer = producer;
}
public void run() {
while(true){
try {
producer.sendMessage("Jaycekon-MQ");
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
运行消费者
package com.slp.activemq;
/**
* @author sanglp
* @create 2017-12-05 11:31
* @desc 消费者测试
**/
public class TestConcumer {
public static void main(String[] args){
Consumer consumer = new Consumer();
consumer.init();
TestConcumer testConsumer = new TestConcumer();
new Thread(testConsumer.new ConsumerMq(consumer)).start();
new Thread(testConsumer.new ConsumerMq(consumer)).start();
new Thread(testConsumer.new ConsumerMq(consumer)).start();
new Thread(testConsumer.new ConsumerMq(consumer)).start();
}
private class ConsumerMq implements Runnable{
Consumer consumer;
public ConsumerMq(Consumer consumer){
this.consumer = consumer;
}
public void run() {
while(true){
try {
consumer.getMessage("Jaycekon-MQ");
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
