用到的jar包:

 

发送类

package com.anhw.test;

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

public class JMSSend {
    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, "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("anhw是一个非常不错的好人!");
        ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session
                .createObjectMessage();
        msg.setObject((Serializable) s);
        producer.send(msg);
    }

    static 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;
        }
    }
}

接收类:

package com.anhw.test;

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

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

import com.anhw.test.JMSSend.Student;

public class ActiveMQReceive {
    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) {
            }
        }
    }
}

 先启动发送类,启动没有问题再启动接收类,如果控制台打印如下消息,则说明测试没有问题:
