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();
        }
    }
}
