解压 启动bin\activemq.bat

生产者接口：

public interface ProducerService {
/**
* 向指定队列发送消息
*/
void sendMessage(Destination destination, final String msg);
/**
* 向默认队列发送消息
*/
void sendMessage(final String msg);
}

消费者接口：

public interface ConsumerService {
/**
* 接受消息
*/
void receive(Destination destination);
}

生产者实现：

@Service("producerService")
public class ProducerServiceImpl implements ProducerService {
@Resource
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);
}
});

}
}

消费者实现：

@Service("consumerService")
public class ConsumerServiceImpl implements ConsumerService {
@Resource
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();
}
}
}
