# spring 整合 rabbitmq #

### （rabbitmq的简单认识） ###

Rabbitmq 是一种消息队列 消息队列都会包含 producer（生产者），consumer（消费者）及broker（代理）

RabbitMQ 是信息传输的中间者。本质上，他从生产者（producers）接收消息，转发这些消息给消费者（consumers）.换句话说，他能够按根据你指定的规则进行消息转发、缓冲、和持久化。

###  （spring+rabbitmq） ###

首先需要启动rabbitmq 可查看http://blog.csdn.net/raccoon\_hzy/article/details/53893379 这个地址进行rabbitmq的安装与启动，接下来就开始入门案例

一个producer发送消息，一个接收者（consumer）接收消息，并在控制台打印出来。

## 1，消息生产者（producer）    ##

###    1.1  创建一个maven项目 ###

###    1.2 在maven项目的pom文件中添加入约束 ###

<dependency>
    			<groupId>org.springframework</groupId>

    			<artifactId>spring-rabbit</artifactId>
    			<version>1.4.1.RELEASE</version>

    			<groupId>org.springframework</groupId>
    			<artifactId>spring-test</artifactId>
    			<version>4.1.3.RELEASE</version>
    		</dependency>

###    1.3 编写spring核心配置文件 applicationContext.properties ###

<?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:rabbit="http://www.springframework.org/schema/rabbit"
    	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/rabbit
                    http://www.springframework.org/schema/rabbit/spring-rabbit-1.4.xsd">
    	
    	<context:component-scan base-package="com.chainhu" />
    	
    	<bean
    		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    		<property name="locations">
    			<list>
    				<value>classpath:application.properties</value>
    			</list>
    		</property>
    	</bean>
    	<import resource="classpath:rabbit-config.xml"/>
    	</beans>

###    1.4 编写参数配置文件 application.properties ###

![Center][]

###    1.5  编写rabbitmq的配置文件rabbit-config.xml ###

###   1.6 编写测试类 test.class ###

@Test
    	public void queueSend(){
    		while(true){
    		QueueMessage qm = new QueueMessage();
    		qm.setCode("0");
    		qm.setOrderId("123456");
    		qm.setDesc("操作成功！");
    		try {
    			Thread.sleep(5000);
    			boolean b = RabbitQueueManager.queueSend(qm);
    			System.out.println(b);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		}
    	}

###   1.7 控制台打印出 true时表示消息发送成功！ ###

## 2  队列消费者（consumer） ##

###    2.1 建立队列消费者 配置文件 rabbit-config-consumer.xml ###

<rabbit:connection-factory id="rabbitConnectionFactory"
    		host="${host}" port="${port}" username="${username}" password="${password}"
    		virtual-host="${virtualhost}" />
    
    	<rabbit:admin connection-factory="rabbitConnectionFactory" />
    	
        
    	
    	
    	<rabbit:queue durable="true" exclusive="false"
    		auto-declare="true" name="${queue}"></rabbit:queue>
    	
    	<bean name="rabbitConsumer" class="com.chainhu.rabbitmq.comsumer.RabbitConsumer"
    		lazy-init="false" />
    	<rabbit:listener-container
    		connection-factory="rabbitConnectionFactory" acknowledge="manual">
    		
    		<rabbit:listener ref="rabbitConsumer" method="onMessage"
    			queue-names="${queue}" />
    	</rabbit:listener-container>

###   2.2 建立队列监听类 RabbitConsumer.class ###

public class RabbitConsumer implements ChannelAwareMessageListener \{  
  
    public void onMessage(Message message, Channel channel) throws Exception \{  
         try\{  
             String respMessage = new String(message.getBody(), "UTF-8");  
             System.out.println("消费者接收到消息："+respMessage);  
             // 确认返回状态  
             channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);  
         \}catch(Exception e)\{  
             e.printStackTrace();  
             channel.basicAck(message.getMessageProperties().getDeliveryTag(), true);  
         \}  
    \}  
  
\}

###   2.3 运行项目 当控制台打印出 ###

<table> 
 <tbody> 
  <tr> 
   <td>{"code":"0","desc":"操作成功！","orderId":"123456"}</td> 
  </tr> 
 </tbody> 
</table>

此时队列消费者建立成功！

spring 整合rabbitmq 简单案例结束！
