五、相关业务实现类

producer相关类:

import org.springframework.jms.core.JmsTemplate;

import javax.jms.Destination;

public abstract class AbstractActivemqProducer {
  private JmsTemplate jmsTemplate;
  private Destination destination;

  public AbstractActivemqProducer(JmsTemplate jmsTemplate, Destination destination) {
    this.jmsTemplate = jmsTemplate;
    this.destination = destination;
  }

  public void send(String msg){
    jmsTemplate.convertAndSend(destination, msg);
  }
}

public class QueueActivemqProducer extends AbstractActivemqProducer {

  public QueueActivemqProducer(JmsTemplate jmsTemplate, Destination destination) {
    super(jmsTemplate, destination);
  }
}

public class TopicActivemqProducer extends AbstractActivemqProducer {

  public TopicActivemqProducer(JmsTemplate jmsTemplate, Destination destination) {
    super(jmsTemplate, destination);
  }
}

customer相关类:

public class CustomerMsgListener implements MessageListener {

    private BusinessHandler businessHandler;

    public CustomerMsgListener(BusinessHandler businessHandler) {
        this.businessHandler = businessHandler;
    }

    @Override
    public void onMessage(Message message) {
        try {
            if (message instanceof TextMessage) {
                businessHandler.handle(((TextMessage) message).getText() );
            }
            if (message instanceof MapMessage) {
                MapMessage mapMessage = (MapMessage) message;
                businessHandler.handle(mapMessage.getString("key01") );
                businessHandler.handle(mapMessage.getString("key02") );
            }
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

public interface BusinessHandler {

    void handle(String msg);
}

public class QueueHandler implements BusinessHandler {
    @Override
    public void handle(String msg) {
        System.out.println("msg = [" + msg + "]");
    }

}

六、测试

public class XmlActivemqTest {

    public static void main(String[] args) {
        customerXml();
    }

    public static void producerXml(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:spring-activemq-producer.xml");
        AbstractActivemqProducer queueActivemqProducer = context.getBean(QueueActivemqProducer.class);
        queueActivemqProducer.send("this is a test");
    }


    public static void customerXml(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:spring-activemq-customer.xml");
    }
}
