Spring整合JMS、IBM MQ发送和接收消息

Spring整合JMS、IBM MQ发送和接收消息

最近才接触到MQ,由于之前完全不知道是干嘛用的,还是很花了一点时间研究的~先来简单解释一下名词啦

一、名词解释

  1. MQ

    MQ(message queue)指消息队列,是应用程序对应用程序的通信方法。可以利用消息队列暂存数据报文。 
    MQ的原理其实就是生产者-消费者模式。有关生产者-消费者模式的详细解释可以看这篇博文http://blog.csdn.net/yolanda_nuonuo/article/details/62038122 
    MQ是一种异步通讯。 
    生产者,发送消息到MQ服务器 
    消费者,到MQ服务器,获取生产者发送的消息(根据MQ的不同配置,可以是MQ推送消息给消费者,或者是消费者主动从MQ获取消息)

  2. JMS

    JMS即 
    JAVA消息服务(Java Message Service),是一个Java平台中关于面向消息中间件(MOM)的API,用于在两个应用程序之间,或分布式系统中发送消息,进行异步通信。

使用JMS 的应用程序被称为JMS 客户端,处理消息路由与传递的消息系统被称为JMS Provider,而JMS 应用则是由多个JMS 客户端和一个JMS Provider 构成的业务系统。 
发送消息的JMS 客户端被称为生产者(producer),而接收消息的JMS 客户端则被称为消费者(consumer)。同一JMS 客户端既可以是生产者也可以是消费者。

所以MQ跟JMS的关系就是,我们可以通过JMS来跟MQ进行通信。

二、具体实现

1.首先是发送数据,新建application-send.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <context:property-placeholder ignore-unresolvable="false" location="classpath:application.properties" /> <context:annotation-config /> <!-- <context:component-scan base-package="com.*" /> --> <bean id="ibmJmsConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory"> <property name="hostName" value="${ibm.mqHostUrl}" /> <property name="port" value="${ibm.mqPort}" /> <property name="CCSID" value="0000" /> <property name="queueManager" value="${ibm.mqManager}" /> <property name="channel" value="${ibm.mqChannel}" /> <property name="transportType" value="1" /> </bean> <bean id="ibmQueueConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="ibmJmsConnectionFactory"/> <property name="sessionCacheSize" value="10"/> </bean> <bean id="ibmQueue" class="com.ibm.mq.jms.MQQueue"> <property name="baseQueueName" value="${ibm.mqName}" /> </bean> <bean id="ibmJmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <property name="connectionFactory" ref="ibmQueueConnectionFactory" /> <property name="defaultDestination" ref="ibmQueue" /> <property name="pubSubDomain" value="false" /> </bean> <bean id="ibmMessageSender" class="com.yolanda.sender.MessageSenderImpl"> </bean> </beans>

2.发送数据的代码 
先写一个接口

public interface MessageSender {

    public void sendMessage(String message); }

再写实现类

import java.io.UnsupportedEncodingException;
import javax.annotation.Resource;
import javax.jms.BytesMessage;
import javax.jms.JMSException;
import javax.jms.Message; import javax.jms.Session; import org.springframework.beans.factory.annotation.Value; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.stereotype.Component; @Component("ibmMessageSender") public class MessageSenderImpl implements MessageSender { @Resource(name="ibmJmsTemplate") private JmsTemplate jmsTemplate; /** * 这里为什么要用final呢?是下面那个createTextMessage方法要求的... */ public void sendMessage(final String message) { this.jmsTemplate.send(new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage(message); } }); } }

3.接下来就是收数据辣,新建application-recv.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <bean id="ibmJmsConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory"> <property name="hostName" value="${ibm.mqHostUrl}" /> <property name="port" value="${ibm.mqPort}" /> <property name="CCSID" value="1381" /> <property name="queueManager" value="${ibm.mqManager}" /> <property name="channel" value="${ibm.mqChannel}" /> <property name="transportType" value="1" /> </bean> <bean id="ibmQueueConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="ibmJmsConnectionFactory"/> <property name="sessionCacheSize" value="10"/> </bean> <bean id="ibmQueue" class="com.ibm.mq.jms.MQQueue"> <property name="baseQueueName" value="MQTEST" /> </bean> <bean id="queueContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="ibmQueueConnectionFactory" /> <property name="destination" ref="ibmQueue" /> <property name="pubSubDomain" value="false" /> <property name="concurrentConsumers" value="20" /> <property name="messageListener" ref="ibmTextMessageListener" /> </bean> <!-- 异步接收消息处理类 --> <bean id="ibmextMessageListener" class="com.yolanda.receive.TextMessageListener" /> </beans>

4.由于整合了Spring,又是用JMS,所以代码还是灰常简单的,这里我们只需要实现MessageListener的onMessage(),监听一下就可以啦

package com.yolanda.receiver;

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

import org.springframework.beans.factory.annotation.Autowired; public class TextMessageListener implements MessageListener { @Autowired public void onMessage(Message message) { try { TextMessage msg = (TextMessage) message; String msgStr = msg.getText(); System.out.println("Receive message:" + msgStr); } catch (Exception e) { e .printStackTrace(); } }

好啦,圆满结束啦,不用spring整合的话,代码还是比较繁琐的,果然还是用比较好呢!
