1、网上的例子都是直接发送文本消息的, 我做了一个简单的变换,就是能够发送和接收对象。

首先,在这里确认一下版本,activemq版本是apache-activemq-5.4.1-bin.zip,activemq安装环境是win7,jdk是1.6版本。下载apache-activemq-5.4.1-bin.zip,到官网

http://activemq.apache.org/download.html,注意找对应的版本,然后下载解压到系统的任意一个目录。

activemq发送和接收对象_apache

如图,我这里是放在了我windows系统的e盘下面,然后双击activemq.bat文件,启动activemq,启动成功会出现下面这个界面:

activemq发送和接收对象_消息发送_02


请注意,如果activemq不能正常启动,出现这个问题的话:

java.io.EOFException: Chunk stream does not exist at page: 0


2、将下载的activemq中的activemq-all-5.4.1.jar导入到工程中


3、发送类

package com.test.activemq;

import java.io.Serializable;

import javax.jms.Connection;  
import javax.jms.ConnectionFactory;  
import javax.jms.DeliveryMode;  
import javax.jms.Destination;  
import javax.jms.MessageProducer;  
import javax.jms.Session;  
import javax.jms.TextMessage;  

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

public class SenderMain {

	private static final int SEND_NUMBER = 5;  
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ConnectionFactory connectionFactory; // Connection :JMS 客户端到JMS 
		// Provider 的连接  
        Connection connection = null; // Session: 一个发送或接收消息的线程  
        Session session; // Destination :消息的目的地;消息发送给谁.  
        Destination destination; // MessageProducer:消息发送者  
        MessageProducer producer; // TextMessage message;  
        // 构造ConnectionFactory实例对象,此处采用ActiveMq的实现jar  
        connectionFactory = new ActiveMQConnectionFactory(  
                ActiveMQConnection.DEFAULT_USER,  
                ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616"); 
        
        try { // 构造从工厂得到连接对象  
            connection = connectionFactory.createConnection();  
            // 启动  
            connection.start();  
            // 获取操作连接  
            session = connection.createSession(Boolean.TRUE,  
                    Session.AUTO_ACKNOWLEDGE);  
            // 获取session注意参数值xingbo.xu-queue是一个服务器的queue,须在在ActiveMq的console配置  
            destination = session.createQueue("FirstQueue");  
            // 得到消息生成者【发送者】  
            producer = session.createProducer(destination);  
            // 设置不持久化,此处学习,实际根据项目决定  
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);  
            // 构造消息,此处写死,项目就是参数,或者方法获取  
            sendMessage(session, producer);  
            session.commit();  
        } catch (Exception e) {  
            e.printStackTrace();  
        } finally {  
            try {  
                if (null != connection)  
                    connection.close();  
            } catch (Throwable ignore) {  
            }  
        }  
	}
	
	/*
	 * 利用activemq发送java对象
	 * */
	public static void sendMessage(Session session, MessageProducer producer)  
            throws Exception {  

		Student s=new Student();
		s.setName("蒋辉文是一个非常不错的好人!");
		ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session.createObjectMessage();
        msg.setObject((Serializable) s);
        producer.send(msg);
    }  

}

class Student implements Serializable
{
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
}


4、接收类

package com.test.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; 
import org.apache.activemq.command.ActiveMQObjectMessage;

public class ReceiveMain {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		// ConnectionFactory :连接工厂,JMS 用它创建连接  
        ConnectionFactory connectionFactory;  
        // Connection :JMS 客户端到JMS Provider 的连接  
        Connection connection = null;  
        // Session: 一个发送或接收消息的线程  
        Session session;  
        // Destination :消息的目的地;消息发送给谁.  
        Destination destination;  
        // 消费者,消息接收者  
        MessageConsumer consumer;  
        connectionFactory = new ActiveMQConnectionFactory(  
                ActiveMQConnection.DEFAULT_USER,  
                ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616");  
        try {  
            // 构造从工厂得到连接对象  
            connection = connectionFactory.createConnection();  
            // 启动  
            connection.start();  
            // 获取操作连接  
            session = connection.createSession(Boolean.FALSE,  
                    Session.AUTO_ACKNOWLEDGE);  
            // 获取session注意参数值xingbo.xu-queue是一个服务器的queue,须在在ActiveMq的console配置  
            destination = session.createQueue("FirstQueue");  
            consumer = session.createConsumer(destination); 
            /*
        	 * 利用activemq接收java对象
        	 * */
            while (true) {  
                // 设置接收者接收消息的时间,为了便于测试,这里谁定为100s  
            	ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session.createObjectMessage();
            	msg = (ActiveMQObjectMessage) consumer.receive(100000);  
            	if(msg != null)
            	{
            		Student s=(Student) msg.getObject();
                	System.out.println("收到的消息对象:"+s.getName());
            	}
            	
               
            }  
        } catch (Exception e) {  
            e.printStackTrace();  
        } finally {  
            try {  
                if (null != connection)  
                    connection.close();  
            } catch (Throwable ignore) {  
            }  
        }  
    }  

}


5、先运行发送类,再运行接收类,会打印出下面的消息


activemq发送和接收对象_消息发送_03


说明运行正常,先给消息中间件发消息,然后从消息中间件接收消息。
