实现代码
- ProducerService 接口及其实现
public interface ProducerService {
/**
* 发送消息
* @param msg 消息
*/
void sendMsg(final String msg);
}
import com.github.houbb.jms.learn.activemq.spring.service.ProducerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
@Service
public class ProducerServiceImpl implements ProducerService {
@Autowired
private JmsTemplate jmsTemplate;
@Autowired
private Destination destination;
@Override
public void sendMsg(String msg) {
System.out.println("生产者发了一个消息：" + msg);
jmsTemplate.send(destination, new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(msg);
}
});
}
}
- ConsunerMessageListener 消息监听器
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
public class ConsunerMessageListener implements MessageListener {
@Override
public void onMessage(Message message) {
//这里我们知道生产者发送的就是一个纯文本消息，所以这里可以直接进行强制转换
TextMessage textMsg = (TextMessage) message;
System.out.println("接收到一个纯文本消息。");
try {
System.out.println("消息内容是：" + textMsg.getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
}
测试
- ActiveMQTest.java
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:application-mq.xml"})
public class ActiveMQTest {
@Autowired
private ProducerService producerService;
@Test
public void sendTest() {
producerService.sendMsg("hello spring activeMQ!");
}
}
- 测试日志
生产者发了一个消息：hello spring activeMQ!
接收到一个纯文本消息。
消息内容是：hello spring activeMQ!
