• 消息生产者:ActiveMQProduce.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;

@Component
public class ActiveMQProduce {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        ActiveMQProduce activeMQProduce = (ActiveMQProduce) applicationContext.getBean("activeMQProduce");
        activeMQProduce.jmsTemplate.send(session -> session.createTextMessage("-------spring activeMQ message--------"));
        System.out.println("--------spring message send success-----------");
    }
}

• 消息消费者–方式一：手动消费 只需要使用jmsTemplate.receiveAndConvert() 即可

//消费
String content = (String)jmsTemplate.receiveAndConvert();

• 消息消费者–方式二：监听消费，实现MessageListener接口，重写onMessage方法，在sping配置中配置监听，如上面applicationContext.xml配置所示（jmsContainer）

import org.springframework.stereotype.Component;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

@Component
public class MyMessageListener implements MessageListener {

    @Override
    public void onMessage(Message message) {
        if (message instanceof TextMessage) {
            TextMessage textMessage = (TextMessage) message;
            try {
                System.out.println("消费：" + textMessage.getText());
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    }
}
