web项目中spring如何整合RabbitMQ？

如何在Windows下安装rabbitMQ？这个问题已在我的上一篇文章中讲解清楚，不清楚的同学可以看看我的上一篇文章。 

Windows下安装及配置RabbitMQ？

接下来讲解如何在web项目中配合spring来使用rabbitMQ？

一、若是maven工程，在pom.xml文件中添加依赖： 若不是maven工程，需自己找jar包加入工程。

<dependency> <groupId>com.rabbitmqgroupId> <artifactId>amqp-clientartifactId> <version>3.5.1version> dependency> <dependency> <groupId>org.springframework.amqpgroupId> <artifactId>spring-rabbitartifactId> <version>1.4.5.RELEASEversion> dependency>

二、项目中新建配置文件 spring-rabbit.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:rabbit="http://www.springframework.org/schema/rabbit" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit-1.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <context:property-placeholder location="classpath*:/META-INF/env/*.properties" /> <rabbit:connection-factory id="connectionFactory" username="guest" password="guest" host="localhost" port="5672" virtual-host="/"/> <rabbit:admin connection-factory="connectionFactory"/> <rabbit:queue id="com.mj.test" name="com.mj.test" durable="true" auto-delete="false" exclusive="false"/> <rabbit:direct-exchange name="myChange" durable="true" auto-delete="false"> <rabbit:bindings> <rabbit:binding queue="com.mj.test" key="testKey">rabbit:binding> rabbit:bindings> rabbit:direct-exchange> <rabbit:template id="amqpTemplate" connection-factory="connectionFactory" exchange="myChange" /> <bean id="messageReceiver" class="com.hp.netpro.rf.web.utils.RabbitMQConsumer"/> <rabbit:listener-container connection-factory="connectionFactory"> <rabbit:listener queues="com.mj.test" ref="messageReceiver"/> rabbit:listener-container> beans>

三、在工程的配置文件applicationContext.xml中增加配置如下：

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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <import resource="classpath*:/META-INF/spring/spring-api-mybatis.xml" /> <import resource="classpath*:/META-INF/spring/spring-rabbit.xml" /> <aop:aspectj-autoproxy/> <context:component-scan base-package="com.hp.netpro.rf.web.utils"/> <context:annotation-config/> <context:property-placeholder location="classpath*:/META-INF/env/*.properties" /> <context:spring-configured /> beans>

四、新建消息生产者类  RabbitMQProducer.java

packagecom.hp.netpro.rf.web.utils; importorg.springframework.amqp.core.AmqpTemplate; importorg.springframework.stereotype.Service; importjavax.annotation.Resource; /**  * @Description:消息生产者  * @Author:  *@CreateTime:  */ @Service public classRabbitMQProducer {     @Resource     privateAmqpTemplateamqpTemplate;     public voidsendMessage(Object message){         amqpTemplate.convertAndSend("testKey",message);//testKey为配置文件中queue对应的key,指明发送给哪个queue。     } }

 

五、新建消息消费者 RabbitMQConsumer.java 

package com.hp.netpro.rf.web.utils; import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageListener; import org.springframework.stereotype.Service; /**  * @Description:消息队列接收者  * @Author:  *@CreateTime:  */ @Service public class RabbitMQConsumerimplementsMessageListener {     public voidonMessage(Message message) {        System.out.println("消息！");        System.out.println(message);        System.out.println("消息getMessageProperties！");        System.out.println(message.getMessageProperties());        System.out.println("消息getBody");        System.out.println(message.getBody());     } }

六、编写测试方法

/**  * @Description:消息队列  * @Author:  *@CreateTime:  */ @Resource private RabbitMQProducer rabbitMQProducer; //注意：这里必须以这种注入的方式 不能使用new来创建对象， @ResponseBody @RequestMapping("/sendMessage") publicString testQueue() {     try{         rabbitMQProducer.sendMessage("I am amq sender");         return"发送完毕";     }catch(Exception e){         e.printStackTrace();         return"发送失败！！";     } }

接下来启动RabbitMQ-Server,启动工程，浏览器访问对应测试方法的RequestMapping。

结果：
