ConsumerQuery01
@Service public class ConsumerQueue01 implements MessageListener{ @Override public void onMessage(Message message) { TextMessage message2 = (TextMessage) message; try { System.out.println("消费者获取消息:"+message2.getText()); } catch (JMSException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
ConsumerQuery02
@Service public class ConsumerQueue02 implements MessageListener{ @Override public void onMessage(Message message) { TextMessage message2 = (TextMessage) message; try { System.out.println("消费者获取消息2:"+message2.getText()); } catch (JMSException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
ConsumerTopic01
@Service public class ConsumerTopic01 implements MessageListener{ @Override public void onMessage(Message message) { TextMessage message2 = (TextMessage) message; try { System.out.println("Topic消费者获取消息:"+message2.getText()); } catch (JMSException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
ConsumerTopic02
@Service public class ConsumerTopic02 implements MessageListener{ @Override public void onMessage(Message message) { TextMessage message2 = (TextMessage) message; try { System.out.println("Topic消费者获取消息2:"+message2.getText()); } catch (JMSException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
QueueSender.java
@Service public class QueueSender { @Autowired @Qualifier("jmsQueueTemplate") private JmsTemplate jmsTemplate; public void send(String QueueName,final String message){ jmsTemplate.send(QueueName, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { TextMessage message2 = session.createTextMessage(message); return message2; } }); } }
TopicSender.java
@Service public class TopicSender { @Autowired @Qualifier("jmsTopicTemplate") private JmsTemplate jmsTemplate; public void send(String topicName,final String message){ jmsTemplate.send(topicName, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { TextMessage message2 = session.createTextMessage(message); return message2; } }); } }
queue 一个生产者 只能让一个消费者消费
如果存在多个消费 ,消费者之间是竞争的关系
Topic 一个生产者 可以让多个消费者消费
生产了一个任务,消费者一起消费这个任务
测试: 生产者
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:applicationContext.xml") public class Demo { @Autowired private QueueSender queueSender; @Autowired private TopicSender topicSender; @Test public void test01(){ queueSender.send("spring_queue", "test"); topicSender.send("spring_topic", "topic_test"); } }
消费者
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:applicationContext-mq-consumer.xml") public class Demo02 { @Test public void test01(){ while(true){ } } }
在测试时一定要先启动消费者再去生产消息 否则topic不会消费消息
