【消息队列】ActiveMQ和Spring整合的一个简单例子

发送方发送消息

package cn.e3mall.activemq;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

public class ActiveMqSpring {

    @Test
    public void sendMessage() throws Exception {
        //初始化spring容器
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
        //从容器中获得JmsTemplate对象。
        JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class);
        //从容器中获得一个Destination对象。
        Destination destination = (Destination) applicationContext.getBean("queueDestination");
        //发送消息
        jmsTemplate.send(destination, new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("send activemq message");
            }
        });
    }
}

</beans>

接收方接收消息

package cn.e3mall.search.message;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

public class MyMessageListener implements MessageListener {

    @Override
    public void onMessage(Message message) {
        //取消息内容
        TextMessage textMessage = (TextMessage) message;
        try {
            String text = textMessage.getText();
            System.out.println(text);
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }

}

初始化spring容器

package cn.e3mall.activemq;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MessageConsumer {

    @Test
    public void msgConsumer() throws Exception {
        //初始化spring容器
        ApplicationContext applicationContext =  new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
        //等待
        System.in.read();
    }
}
