1、配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- 配置JMS连接工厂 --> <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="failover:(tcp://192.168.147.131:61616)" /> </bean> <!-- 定义消息队列(Queue) --> <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue"> <!-- 设置消息队列的名字 --> <constructor-arg> <value>testSpringQueue</value> </constructor-arg> </bean> <!-- 配置JMS模板(Queue),Spring提供的JMS工具类,它发送、接收消息。 --> <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <property name="connectionFactory" ref="connectionFactory" /> <property name="defaultDestination" ref="queueDestination" /> <property name="receiveTimeout" value="10000" /> </bean> </beans>
2、生产者代码
package com.mq.spring.queue; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import javax.annotation.Resource; import javax.jms.*; /** * created on 2015/6/4 * @author dennisit@163.com * @version 1.0 */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath:spring-mq-queue.xml"}) public class QueueSender { @Resource private JmsTemplate jmsTemplate; @Test public void send(){ sendMqMessage(null,"spring activemq queue type message !"); } /** * 说明:发送的时候如果这里没有显示的指定destination.将用spring xml中配置的destination * @param destination * @param message */ public void sendMqMessage(Destination destination, final String message){ if(null == destination){ destination = jmsTemplate.getDefaultDestination(); } jmsTemplate.send(destination, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage(message); } }); System.out.println("spring send message..."); } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } }
3、消费者代码
package com.mq.spring.queue; import org.junit.Test; import javax.jms.*; import org.junit.runner.RunWith; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import javax.annotation.Resource; import javax.jms.Message; /** * created on 2015/6/4 * @author dennisit@163.com * @version 1.0 */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath:spring-mq-queue.xml"}) public class QueueReceiver { @Resource private JmsTemplate jmsTemplate; @Test public void receiveMqMessage(){ Destination destination = jmsTemplate.getDefaultDestination(); receive(destination); } /** * 接受消息 */ public void receive(Destination destination) { TextMessage tm = (TextMessage) jmsTemplate.receive(destination); try { System.out.println("从队列" + destination.toString() + "收到了消息: " + tm.getText()); } catch (JMSException e) { e.printStackTrace(); } } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } }
程序运行结果:
说明:上面的生产者和消费者使用同一套配置文件,使用独立的程序去接收消息,spring jms也提供了消息监听处理.接下来我们换成监听式消费
配置文件如下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- 配置JMS连接工厂 --> <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="failover:(tcp://192.168.147.131:61616)" /> </bean> <!-- 定义消息队列(Queue) --> <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue"> <!-- 设置消息队列的名字 --> <constructor-arg> <value>testSpringQueue</value> </constructor-arg> </bean> <!-- 配置消息队列监听者(Queue) --> <bean id="consumerMessageListener" class="com.mq.spring.queue.ConsumerMessageListener" /> <!-- 消息监听容器(Queue),配置连接工厂,监听的队列是testSpringQueue,监听器是上面定义的监听器 --> <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueDestination" /> <property name="messageListener" ref="consumerMessageListener" /> </bean> </beans>
这样我们的消息消费就可以在监听器中处理消费了.生产的代码不变,修改发送者的消息体内容,执行生产程序.可以看到运行效果如下:
