1.使用maven管理依赖包
junit junit 4.12 test org.apache.activemq activemq-all 5.11.0 org.springframework spring-jms 4.1.4.RELEASE org.springframework spring-test 4.1.4.RELEASE
2.队列消息的收发
2.1Spring配置文件
queue1
2.2消息生产者代码
package guo.examples.mq02.queue; import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Session; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; public class ProducerServiceImpl implements ProducerService { private JmsTemplate jmsTemplate; /** * 向指定队列发送消息 */ public void sendMessage(Destination destination, final String msg) { System.out.println("向队列" + destination.toString() + "发送了消息------------" + msg); jmsTemplate.send(destination, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage(msg); } }); } /** * 向默认队列发送消息 */ public void sendMessage(final String msg) { String destination = jmsTemplate.getDefaultDestination().toString(); System.out.println("向队列" +destination+ "发送了消息------------" + msg); jmsTemplate.send(new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage(msg); } }); } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } }
2.3消息消费者代码
package guo.examples.mq02.queue; import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.TextMessage; import org.springframework.jms.core.JmsTemplate; public class ConsumerServiceImpl implements ConsumerService { private JmsTemplate jmsTemplate; /** * 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:\t" + tm.getText()); } catch (JMSException e) { e.printStackTrace(); } } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } }
2.4队列消息监听
queue2
package guo.examples.mq02.queue; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; public class QueueMessageListener implements MessageListener { //当收到消息时,自动调用该方法。 public void onMessage(Message message) { TextMessage tm = (TextMessage) message; try { System.out.println("ConsumerMessageListener收到了文本消息:\t" + tm.getText()); } catch (JMSException e) { e.printStackTrace(); } } }
3.主题消息收发
在使用Spring JMS的时候,主题(Topic)和队列消息的主要差异体现在JmsTemplate中"pubSubDomain"是否设置为True。如果为True,则是Topic;如果是false或者默认,则是queue。
<
property
name
=
"pubSubDomain"
value
=
"true"
/>
3.1Spring配置
guo_topic
3.2消息发布者
package guo.examples.mq02.topic; import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Session; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; public class TopicProvider { private JmsTemplate topicJmsTemplate; /** * 向指定的topic发布消息 * * @param topic * @param msg */ public void publish(final Destination topic, final String msg) { topicJmsTemplate.send(topic, new MessageCreator() { public Message createMessage(Session session) throws JMSException { System.out.println("topic name 是" + topic.toString() + ",发布消息内容为:\t" + msg); return session.createTextMessage(msg); } }); } public void setTopicJmsTemplate(JmsTemplate topicJmsTemplate) { this.topicJmsTemplate = topicJmsTemplate; } }
3.3消息订阅者(监听)
package guo.examples.mq02.topic; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; /** *和队列监听的代码一样。 */ public class TopicMessageListener implements MessageListener { public void onMessage(Message message) { TextMessage tm = (TextMessage) message; try { System.out.println("TopicMessageListener \t" + tm.getText()); } catch (JMSException e) { e.printStackTrace(); } } }
4.测试
4.1 测试代码
package guo.examples.mq02; import javax.jms.Destination; import guo.examples.mq02.queue.ConsumerService; import guo.examples.mq02.queue.ProducerService; import guo.examples.mq02.topic.TopicProvider; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; /** * 测试Spring JMS * * 1.测试生产者发送消息 * * 2. 测试消费者接受消息 * * 3. 测试消息监听 * * 4.测试主题监听 * */ @RunWith(SpringJUnit4ClassRunner.class) // ApplicationContext context = new // ClassPathXmlApplicationContext("applicationContext.xml"); @ContextConfiguration("/applicationContext.xml") public class SpringJmsTest { /** * 队列名queue1 */ @Autowired private Destination queueDestination; /** * 队列名queue2 */ @Autowired private Destination queueDestination2; /** * 主题 guo_topic */ @Autowired @Qualifier("topicDestination") private Destination topic; /** * 主题消息发布者 */ @Autowired private TopicProvider topicProvider; /** * 队列消息生产者 */ @Autowired @Qualifier("producerService") private ProducerService producer; /** * 队列消息生产者 */ @Autowired @Qualifier("consumerService") private ConsumerService consumer; /** * 测试生产者向queue1发送消息 */ @Test public void testProduce() { String msg = "Hello world!"; producer.sendMessage(msg); } /** * 测试消费者从queue1接受消息 */ @Test public void testConsume() { consumer.receive(queueDestination); } /** * 测试消息监听 * * 1.生产者向队列queue2发送消息 * * 2.ConsumerMessageListener监听队列,并消费消息 */ @Test public void testSend() { producer.sendMessage(queueDestination2, "Hello China~~~~~~~~~~~~~~~"); } /** * 测试主题监听 * * 1.生产者向主题发布消息 * * 2.ConsumerMessageListener监听主题,并消费消息 */ @Test public void testTopic() throws Exception { topicProvider.publish(topic, "Hello T-To-Top-Topi-Topic!"); } }
4.2 测试结果
topic name 是topic:
//guo_topic
,发布消息内容为: Hello T-To-Top-Topi-Topic!
TopicMessageListener Hello T-To-Top-Topi-Topic!
向队列queue:
//queue2
发送了消息------------Hello China~~~~~~~~~~~~~~~
ConsumerMessageListener收到了文本消息: Hello China~~~~~~~~~~~~~~~
向队列queue:
//queue1
发送了消息------------Hello world!
从队列queue:
//queue1
收到了消息: Hello world!
