ProducerService接口
package com.cn.activemq;
import javax.jms.Destination; public interface ProducerService { public void sendMessage(Destination destination, final String message); }
ProducerServiceimpl实现类
package com.cn.activemq; import javax.annotation.Resource; 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; import org.springframework.stereotype.Component; @Component public class ProducerServiceImpl implements ProducerService { private JmsTemplate jmsTemplate; public JmsTemplate getJmsTemplate() { return jmsTemplate; } @Resource public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } @Override public void sendMessage(Destination destination, String message) { System.out.println("--------------生产者要发信息----------------"); System.out.println("生产者发了一个信息"+message); jmsTemplate.send(destination,new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { return session.createTextMessage(message); } }); } }
ConsumerMessageListener监听
package com.cn.activemq; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class ConsumerMessageListener implements MessageListener { private static Logger log = LoggerFactory.getLogger(ConsumerMessageListener.class); @Override public void onMessage(Message message) { //这里我们知道生产者发送的就是一个消息， //所以这里可以直接进行强制转换，或者直接g把onMessae方法的参数 //改成Message的子类TextMessage TextMessage mes = (TextMessage)message; System.out.println("接收到路径"); log.info("接收到路径"); try { System.out.println(" 路径是:"+mes.getText()); log.info("路径是:"+mes.getText()); } catch (JMSException e) { e.printStackTrace(); } } }
Test测试
package test; import javax.jms.Destination; 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; import com.cn.activemq.ProducerService; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath:spring/spring-*.xml"}) public class Testte { @Autowired private ProducerService producerService; @Autowired @Qualifier("queueDestination") private Destination destination; @Test public void testSend() { for (int i=0; i<2; i++) { producerService.sendMessage(destination, "你好，生产者！这是消息：" + (i+1)); } } }
