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>
            classpath*:/applicationContext.xml,
            classpath*:/applicationContext-shiro.xml,
            classpath*:/applicationContext-activemq.xml
        </param-value>
    </context-param>

    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:/applicationContext-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

10.启动服务，浏览器访问接口路径，测试发送消息是否成功！
