ActiveMQ（四）：Topic方式使用MessageListener监听的方式接收消息

发布/订阅模式

消息发布者：

xml配置：

<?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">     <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">        <property name="brokerURL" value="tcp://localhost:61616" />        <property name="userName" value="admin" />        <property name="password" value="admin" />    </bean>    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">        <property name="connectionFactory" ref="connectionFactory" />    </bean>    <bean id="destination" class="org.apache.activemq.command.ActiveMQTopic">        <!-- 设置消息队列的名字 -->        <constructor-arg index="0" value="STATUS" />    </bean> </beans>

发送消息：

package ActiveMQ;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.Session;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;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 FileSystemXmlApplicationContext("conf/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");    }}

xml配置：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:task="http://www.springframework.org/schema/task"     xmlns:util="http://www.springframework.org/schema/util"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:p="http://www.springframework.org/schema/p"    xmlns:jaxrs="http://cxf.apache.org/jaxrs"     xmlns:jaxws="http://cxf.apache.org/jaxws"    xsi:schemaLocation="    http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans.xsd    http://www.springframework.org/schema/aop    http://www.springframework.org/schema/aop/spring-aop.xsd    http://www.springframework.org/schema/task     http://www.springframework.org/schema/task/spring-task-3.0.xsd    http://www.springframework.org/schema/util    http://www.springframework.org/schema/util/spring-util-2.5.xsd    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd    http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd    http://cxf.apache.org/transports/http/configuration        http://cxf.apache.org/schemas/configuration/http-conf.xsd">    <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">        <property name="brokerURL" value="tcp://localhost:61616" />        <property name="userName" value="admin" />        <property name="password" value="admin" />    </bean>      <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">        <property name="connectionFactory" ref="connectionFactory" />    </bean>    <bean id="mqDestination" class="org.apache.activemq.command.ActiveMQTopic">        <!-- 设置消息队列的名字 -->        <constructor-arg index="0" value="STATUS" />    </bean>    <bean id="messageListener" class="activeMQ.ConsumerMessageListener"></bean>    <bean id="listenerContainer" class="org.springframework.jms.listener.SimpleMessageListenerContainer">        <property name="connectionFactory" ref="connectionFactory" />        <property name="destination" ref="mqDestination" />        <property name="messageListener" ref="messageListener" />    </bean> </beans>

消息监听者：

package activeMQ;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.ObjectMessage;import javax.jms.TextMessage;import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;import org.springframework.jms.core.JmsTemplate;//监听代码 public class ConsumerMessageListener implements MessageListener{    @Override    public void onMessage(Message message) {        // TODO Auto-generated method stub        System.out.println("topic收到的消息："+message);        TextMessage textmessage = (TextMessage)message;        try {            System.out.println("message："+textmessage.getText());        } catch (JMSException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}

消费者代码：

package activeMQ;import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;//这是消费者代码，这里你可以创建多个XML文件，模拟多个消费者public class JmsTopicReceiver {    public static void main(String[] args){        //加载消费者监听        ApplicationContext ctx = new FileSystemXmlApplicationContext("conf/applicationContext.xml");        //写个死循环        while(true){}    }}

测试：
先启动消息监听者JmsTopicReceiver：

再启动消息发送端：

在监控端即可监控到发送的消息：
