• 消息中间件activemq-5.13.0整合spring


    首先说明这里是在qctivemq配置好并启动服务的情况下进行,请先自行配置好。也可关注我的博文(消息中间件qctivemq安全验证配置)进行配置。

    1.首先看一下项目结构

    2.所需jar包,这里只列出mq相关jar包,spring相关不与说明。

    3.消息生产service  QueueMessageProducer

    package cn.carowl.activemq;
    
    import javax.jms.Destination;
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.Session;
    
    import org.springframework.jms.core.JmsTemplate;
    import org.springframework.jms.core.MessageCreator;
    
    /**
     * 消息生产者service
     * @author weishengbin
     *
     */
    public class QueueMessageProducer {
        private JmsTemplate jmsTemplate;
        private Destination notifyQueue;
        private NotifyMessageConverter messageConverter;
    
        public void sendQueue(String noticeInfo) {
            sendMessage(noticeInfo);
        }
    
        private void sendMessage(final String noticeInfo) {
            this.jmsTemplate.send(notifyQueue, new MessageCreator() {  
                public Message createMessage(Session session) throws JMSException {  
                    return session.createObjectMessage(noticeInfo); 
                }
      
            }); 
        }
    
        public JmsTemplate getJmsTemplate() {
            return jmsTemplate;
        }
    
        public void setJmsTemplate(JmsTemplate jmsTemplate) {
            this.jmsTemplate = jmsTemplate;
        }
    
        public Destination getNotifyQueue() {
            return notifyQueue;
        }
    
        public void setNotifyQueue(Destination notifyQueue) {
            this.notifyQueue = notifyQueue;
        }
    
        public NotifyMessageConverter getMessageConverter() {
            return messageConverter;
        }
    
        public void setMessageConverter(NotifyMessageConverter messageConverter) {
            this.messageConverter = messageConverter;
        }
    }

    4.消息转换NotifyMessageConverter

    package cn.carowl.activemq;
    
    import java.io.Serializable;
    
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.ObjectMessage;
    import javax.jms.Session;
    
    import org.apache.activemq.command.ActiveMQObjectMessage;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.jms.support.converter.MessageConversionException;
    import org.springframework.jms.support.converter.MessageConverter;
    
    /**
     * 消息转换
     * @author weishengbin
     *
     */
    public class NotifyMessageConverter implements MessageConverter {
        private static Logger logger = LoggerFactory.getLogger(NotifyMessageConverter.class);
    
        /**
         * 转换NoticeInfo对象到消息
         */
        public Message toMessage(Object object, Session session) throws JMSException, MessageConversionException {      
            System.out.println("sendMessage:"+object.toString());  
            ActiveMQObjectMessage msg = (ActiveMQObjectMessage) session.createObjectMessage();
            msg.setObject((Serializable) object);
            return msg;
        }
        
        /**
         * 转换接收到的消息为NoticeInfo对象
         */
        public Object fromMessage(Message message) throws JMSException, MessageConversionException {
            if (logger.isDebugEnabled()) {
                logger.debug("Receive JMS message :" + message);
            }
            if (message instanceof ObjectMessage) {
                ObjectMessage oMsg = (ObjectMessage) message;
                if (oMsg instanceof ActiveMQObjectMessage) {
                    ActiveMQObjectMessage aMsg = (ActiveMQObjectMessage) oMsg;
                    try {
                        Object object = aMsg.getObject();
                        String noticeInfo = object.toString();
                        return noticeInfo;
                    } catch (Exception e) {
                        logger.error("Message:${} is not a instance of NoticeInfo." + message.toString());
                        throw new JMSException(
                                "Message:" + message.toString() + "is not a instance of NoticeInfo." + message.toString());
                    }
                } else {
                    logger.error("Message:${} is not a instance of ActiveMQObjectMessage." + message.toString());
                    throw new JMSException("Message:" + message.toString() + "is not a instance of ActiveMQObjectMessage."
                            + message.toString());
                }
            } else {
                logger.error("Message:${} is not a instance of ObjectMessage." + message.toString());
                throw new JMSException(
                        "Message:" + message.toString() + "is not a instance of ObjectMessage." + message.toString());
            }
        }
    }

    5.监听接收消息QueueMessageListener

    package cn.carowl.activemq;
    
    import javax.jms.Message;
    import javax.jms.MessageListener;
    import javax.jms.ObjectMessage;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    /**
     * 监听接收消息
     * @author weishengbin
     *
     */
    public class QueueMessageListener  implements MessageListener {
        private static Logger logger = LoggerFactory.getLogger(QueueMessageListener.class);
        private NotifyMessageConverter messageConverter;
    
        /**
         * 接收消息
         */
        public void onMessage(Message message) {
            
            try {
                
                ObjectMessage textMessage = (ObjectMessage) message;
                String str = (String)messageConverter.fromMessage(textMessage);
                System.out.println("接收到的消息:"+str);
    
            } catch (Exception e) {
                logger.error("处理信息时发生异常", e);
            }
        }
    
        public NotifyMessageConverter getMessageConverter() {
            return messageConverter;
        }
    
        public void setMessageConverter(NotifyMessageConverter messageConverter) {
            this.messageConverter = messageConverter;
        }
    }

    6.消息生产者Sender

    package cn.carowl.activemq;
    
    import javax.servlet.ServletContext;
    
    import org.springframework.beans.factory.BeanFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    /**
     * 消息生产者
     * @author weishengbin
     *
     */
    @Service
    public class Sender {
         private static ServletContext servletContext;
         private static BeanFactory factory;
         @Autowired
         private QueueMessageProducer notifyMessageProducer;
         
         
        /**
         * 发送点对点信息
         * 
         * @param noticeInfo
         */
        public void setQueueSender(String obj) {
    //        factory = new ClassPathXmlApplicationContext("classpath:/applicationContext-activemq.xml");
    //        factory.getBean("queueMessageProducer");
    //        QueueMessageProducer notifyMessageProducer = ((QueueMessageProducer) factory.getBean("queueMessageProducer"));
            notifyMessageProducer.sendQueue(obj);
        }
    
        public static ServletContext getServletContext() {
            return servletContext;
        }
    
        public static void setServletContext(ServletContext servletContext) {
            Sender.servletContext = servletContext;
        }
    
        public static BeanFactory getFactory() {
            return factory;
        }
    
        public static void setFactory(BeanFactory factory) {
            Sender.factory = factory;
        }
    
    }

    7.发送消息TestSend

    package cn.carowl.activemq;
    
    import javax.annotation.Resource;
    
    import org.springframework.http.MediaType;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    @RequestMapping("/api")
    public class TestSend {
        @Resource(name="sender")
        private Sender sender;
        
        @RequestMapping(value = "/send/test",
                method = RequestMethod.GET,
                produces = MediaType.APPLICATION_JSON_VALUE)
        @ResponseBody
        public void send() {
            sender.setQueueSender("发送的消息");
        }
    }

    9.配置前端控制器web.xml

        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>

    10.启动服务,浏览器访问接口路径,测试发送消息是否成功!
