消息队列之ActiveMQ简单环境搭建

准备:

　　　环境:win7,Eclipse,jdk1.8

　　　ActiveMQ版本:ActiveMQ 5.9.0 Release下载地址:http://activemq.apache.org/download-archives.html

开始:

　　1.下载完后进行解压,解压完找到其中的activemq-all-5.9.0.jar包.

　　2.Eclipse创建一个java项目,导入上面这个jar包

　　3.创建生产者和消费者类

　　生产者

package com.sinosoft.activemq;


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 javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnection;
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;
	//默认连接地址
	private static final String BROKERURL = ActiveMQConnection.DEFAULT_BROKER_URL;
	//发送的消息数量
	private static final int SENDNUM = 10;
	
	
	public static void main(String[] args) {
		//连接工厂
		ConnectionFactory connectionFactory;
		//连接
		Connection connection = null;
		//会话,接收或者发送消息的线程
		Session session;
		//消息的目的地
		Destination destination;
		//消息生产者
		MessageProducer messageProducer;
		//实例化连接工厂
		connectionFactory = new ActiveMQConnectionFactory(JMSProducer.USERNAME, JMSProducer.PASSWORD, JMSProducer.BROKERURL);
		
		try {
			//通过连接工厂获取连接
			connection = connectionFactory.createConnection();
			//启动连接
			connection.start();
			//创建session
			session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
			//创建一个名称为Hello World!的消息队列
			destination = session.createQueue("Hello World");
			//创建消息生产者
			messageProducer = session.createProducer(destination);
			//发送消息
			sendMessage(session,messageProducer);
			
			session.commit();
			
		} catch (Exception e) {
			e.printStackTrace();
		} finally{
			if(connection != null){
				try {
					connection.close();
				} catch (JMSException e) {
					e.printStackTrace();
				}
			}
		}
		
	}
	
	/**
	 * 发送消息
	 * @param session
	 * @param messageProducer 消息生产者
	 * @throws Exception
	 */
	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.err.println("发送消息:activemq 发送消息:" + i);
			//通过消息生产者发出消息
			messageProducer.send(message);
		}
	}
	
}

　　消费者

package com.sinosoft.activemq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

public class JMSConsumer {

	//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;
	//默认连接地址
	private static final String BROKERURL = ActiveMQConnection.DEFAULT_BROKER_URL;
	
	public static void main(String[] args) {
		//连接工厂
		ConnectionFactory connectionFactory;
		//连接
		Connection connection = null;
		//会话,接收或者发送消息的线程
		Session session;
		//消息目的地
		Destination destination;
		//消息的消费者
		MessageConsumer messageConsumer;
		//实例化连接工厂
		connectionFactory = new ActiveMQConnectionFactory(JMSConsumer.USERNAME, JMSConsumer.PASSWORD, JMSConsumer.BROKERURL);
		
		try {
			//通过工厂获取连接
			connection = connectionFactory.createConnection();
			//启动连接
			connection.start();
			//创建会话
			session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
			//创建一个连接Hello World!的消息队列
			destination = session.createQueue("Hello World");
			//创建消息的消费者
			messageConsumer = session.createConsumer(destination);
			
			while(true){
				TextMessage textMessage = (TextMessage) messageConsumer.receive(100000);
				if (textMessage != null) {
					System.err.println("收到的消息:" + textMessage.getText());
				} else {
					break;
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

从解压的压缩包找到bin目录下的activemq.bat并运行它
