本文有两篇参考文献,因此有两个实例,项目结构如下图所示:

在Spring停集成ActiveMQ

3.实例1

信息发送者:HelloSender.java

package edu.sjtu.erplab.springactivemq;import javax.jms.JMSException;import javax.jms.Session;import javax.jms.Destination;import javax.jms.Message;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.jms.core.JmsTemplate;import org.springframework.jms.core.MessageCreator;public class HelloSender {    /**     * @param args     * jmsTemplate和destination都是在spring配置文件中进行配制的     * Sender只使用了配置文件中的jmsFactory,jmsTemplate,还有destination这三个属性     */    public static void main(String[] args) {        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");        JmsTemplate template = (JmsTemplate) applicationContext.getBean("jmsTemplate");        Destination destination = (Destination) applicationContext.getBean("destination");        template.send(destination, new MessageCreator() {            public Message createMessage(Session session) throws JMSException {                return session.createTextMessage("发送消息:Hello ActiveMQ Text Message2!");            }        });        System.out.println("成功发送了一条JMS消息");    }}

信息接受者:ProxyJMSConsumer.java

package edu.sjtu.erplab.springactivemq;import javax.jms.Destination;import javax.jms.TextMessage;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.jms.core.JmsTemplate;/** * JMS消费者 * 消息题的内容定义 * 消息对象 接收消息对象后: 接收到的消息体* <p>  */public class ProxyJMSConsumer {    public ProxyJMSConsumer() {    }    private JmsTemplate jmsTemplate;    public JmsTemplate getJmsTemplate() {        return jmsTemplate;    }    public void setJmsTemplate(JmsTemplate jmsTemplate) {        this.jmsTemplate = jmsTemplate;    }        /**     * 监听到消息目的有消息后自动调用onMessage(Message message)方法     */    public void recive() {        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");        Destination destination = (Destination) applicationContext.getBean("destination");        while (true) {            try {                TextMessage txtmsg = (TextMessage) jmsTemplate                        .receive(destination);                if (null != txtmsg) {                    System.out.println("[DB Proxy] " + txtmsg);                    System.out.println("[DB Proxy] 收到消息内容为: "                            + txtmsg.getText());                } else                    break;            } catch (Exception e) {                e.printStackTrace();            }        }    }}

客户端:JMSTest.java

package edu.sjtu.erplab.springactivemq;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class JMSTest {    /**     * @param args     */    public static void main(String[] args) {        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");        ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext.getBean("messageReceiver");        proxyJMSConsumer.recive();                System.out.println("初始化消息消费者");    }}

Spring配置文件:applicationContext-jms.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-2.5.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-2.5.xsd"    default-autowire="byName">    <!-- 配置connectionFactory -->    <bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory"        destroy-method="stop">        <property name="connectionFactory">            <bean class="org.apache.activemq.ActiveMQConnectionFactory">                <property name="brokerURL">                    <value>tcp://127.0.0.1:61616</value>                </property>            </bean>        </property>        <property name="maxConnections" value="100"></property>    </bean>    <!-- Spring JMS Template -->    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">        <property name="connectionFactory">            <ref local="jmsFactory" />        </property>        <property name="defaultDestinationName" value="subject" />        <!-- 区别它采用的模式为false是p2p为true是订阅 -->        <property name="pubSubDomain" value="true" />    </bean>    <!-- 发送消息的目的地(一个队列) -->    <bean id="destination" class="org.apache.activemq.command.ActiveMQTopic">        <!-- 设置消息队列的名字 -->        <constructor-arg index="0" value="subject" />    </bean>    <bean id="messageReceiver" class="edu.sjtu.erplab.springactivemq.ProxyJMSConsumer">        <!--alt="在Spring停集成ActiveMQ">

测试方法:首先运行JMSTest,然后运行HelloSender。
