RabbitMQ安装和使用（和Spring集成）

一、安装Rabbit MQ　　

　　Rabbit MQ 是建立在强大的Erlang OTP平台上，因此安装Rabbit MQ的前提是安装Erlang。通过下面两个连接下载安装3.2.3 版本：

下载并安装 Eralng OTP For Windows (vR16B03)
运行安装 Rabbit MQ Server Windows Installer (v3.2.3)
具体操作步骤参考：在 Windows 上安装Rabbit MQ 指南
本人遇到的问题

  当安装RabbitMQ后，使用rabbitmqctl，rabbitmq-plugins等相应的命令，出现如下错误：* connected to epmd (port 4369) on mqmaster* epmd reports node 'rabbit' running on port 25672* TCP connection succeeded but Erlang distribution failed* suggestion: hostname mismatch?* suggestion: is the cookie set correctly?* suggestion: is the Erlang distribution using TLS?

　　原因是，安装 Rabbit MQ的过程中没有使用默认的安装路径。重新安装并使用默认的安装路径就没有问题了。如果使用自定义路径，需要同步 Erlang Cookies。具体解释请参考官网中的解释：http://www.rabbitmq.com/install-windows-manual.html （在Finding Command Scripts and App Data 标题下）。

二、Spring集成Rabbit MQ示例1

　　1.创建一个新的maven工程demo1。

　　2.pom文件依赖如下。

    <dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency><dependency><groupId>org.springframework.amqp</groupId><artifactId>spring-rabbit</artifactId><version>1.6.1.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>4.3.1.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.3.1.RELEASE</version></dependency>

　　3.创建application.properties文件。

#mq
mq.username=guest
mq.password=guest
mq.addresses=127.0.0.1:5672

　　4.创建spring公共配置文件applicationContext.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"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"default-lazy-init="true"><description>Spring公共配置</description><bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath*:application.properties</value></list></property></bean><bean id="configProperties"class="org.springframework.beans.factory.config.PropertiesFactoryBean"><property name="locations"><list><value>classpath*:application.properties</value></list></property></bean><context:component-scan base-package="com.hjz.rabbit" />
</beans>

　　5.创建Rabbit MQ的配置文件。

<?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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/rabbithttp://www.springframework.org/schema/rabbit/spring-rabbit-1.4.xsd"><description>rabbitmq 连接服务配置</description><!-- 连接配置 --><rabbit:connection-factory id="connectionFactory" addresses="${mq.addresses}"  username="${mq.username}" password="${mq.password}" /><rabbit:admin connection-factory="connectionFactory"/><!-- spring template声明--><rabbit:template id="amqpTemplate" exchange="test-mq-exchange"  connection-factory="connectionFactory"  message-converter="jsonMessageConverter" /><!-- 消息对象json转换类 --><bean id="jsonMessageConverter" class="org.springframework.amqp.support.converter.Jackson2JsonMessageConverter" /><!-- 消息队列Queue durable:是否持久化exclusive: 仅创建者可以使用的私有队列，断开后自动删除auto_delete: 当所有消费客户端连接断开后，是否自动删除队列--><rabbit:queue id="test_queue_id" name="test_queue_name" durable="true" auto-delete="false" exclusive="false" /><!-- 交换机定义rabbit:direct-exchange：定义exchange模式为direct，意思就是消息与一个特定的路由键完全匹配，才会转发。 rabbit:binding：设置消息queue匹配的key 打印的消息实体：(Body:'{"id":"02cf5aee-d56d-4b54-ad76-a7ec6d4720b6","type":null,"params":null,"body":"大家好，我是hjzgg!!!"}' MessageProperties [headers={__TypeId__=com.hjz.rabbit.common.MqMessage}, timestamp=null, messageId=null, userId=null, receivedUserId=null, appId=null, clusterId=null, type=null, correlationId=null, correlationIdString=null, replyTo=null, contentType=application/json, contentEncoding=UTF-8, contentLength=0, deliveryMode=null, receivedDeliveryMode=PERSISTENT, expiration=null, priority=0, redelivered=false, receivedExchange=, receivedRoutingKey=test_queue_name, receivedDelay=null, deliveryTag=1, messageCount=0, consumerTag=amq.ctag-HyePMBO-c59W3z9q9DRaug, consumerQueue=test_queue_name])key 对应的就是  receivedRoutingKey 对应的值， 而这个值就是在 amqpTemplate.convertAndSend(queueName, message) 中的 queueName。如果rabbit:template 不配置 exchange属性，那么 receivedRoutingKey 就是 队列的 name值--><rabbit:direct-exchange name="test-mq-exchange" durable="true" auto-delete="false" id="test-mq-exchange"><rabbit:bindings><rabbit:binding queue="test_queue_name" key="test_queue_routing_key"/></rabbit:bindings></rabbit:direct-exchange><!-- 监听配置queues：监听的队列，多个的话用逗号（,）分隔 ref：监听器--><rabbit:listener-container connection-factory="connectionFactory" acknowledge="auto"><rabbit:listener queues="test_queue_name" ref="queueListenter"/></rabbit:listener-container>
</beans>

View Code

　　6.新建MQ消息实体类（MqMessage.java）。

public class MqMessage implements Serializable {private static final long serialVersionUID = -6791105187137215924L;private String id;private String type;//保留参数private Object params;private Object body;public String getId() {return id;}public void setId(String id) {this.id = id;}public String getType() {return type;}public void setType(String type) {this.type = type;}public Object getBody() {return body;}public void setBody(Object body) {this.body = body;}public Object getParams() {return params;}public void setParams(Object params) {this.params = params;}}

View Code

　　7.新建MQ消息发送接口（MQSender.java）。

import com.hjz.rabbit.common.MqMessage;
public interface MQSender {/*** 发送消息到指定队列* @param message* @param queueName*/void sendMessage(MqMessage message, String queueName);
}

　　8.新建MQ消息发送实现类 MQSenderImpl.java。

import java.util.UUID;import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;import com.hjz.rabbit.api.MQSender;
import com.hjz.rabbit.common.MqMessage;@Component
public class MQSenderImpl implements MQSender {@Autowiredprivate AmqpTemplate amqpTemplate;@Overridepublic void sendMessage(MqMessage message, String queueName) {if(message==null){System.out.println("消息发送失败：消息为null");return;}if(message.getId()==null){message.setId(UUID.randomUUID().toString());            }amqpTemplate.convertAndSend(queueName, message);}
}/*convertAndSend：将Java对象转换为消息发送到匹配Key的交换机中Exchange，由于配置了JSON转换，这里是将Java对象转换成JSON字符串的形式。　　原文：Convert a Java object to an Amqp Message and send it to a default exchange with a specific routing key.
*/

　　9.创建消息监听器QueueListenter.java。

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.stereotype.Component;@Component("queueListenter")
public class QueueListenter implements MessageListener {@Overridepublic void onMessage(Message msg) {try{System.out.print(msg.toString());}catch(Exception e){e.printStackTrace();}}}

　　10.终于到最后一步了，新建测试类。

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.hjz.rabbit.api.MQSender;
import com.hjz.rabbit.common.MqMessage;@RunWith(value = SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:applicationContext.xml", "classpath*:applicationContext-mq.xml"})
public class TestQueue{@Autowiredprivate MQSender mqSender;final String queueName = "test_queue_routing_key";@Testpublic void send(){MqMessage message = new MqMessage();message.setBody("大家好，我是hjzgg!!!");mqSender.sendMessage(message, queueName);}
}

　　11.最终结果，消息监听器中的输出如下。

(Body:'{"id":"723db571-1b0e-4ea5-aad4-dbfed01d158a","type":null,"params":null,"body":"大家好，我是hjzgg!!!"}' MessageProperties [headers={__TypeId__=com.hjz.rabbit.common.MqMessage}, timestamp=null, messageId=null, userId=null, receivedUserId=null, appId=null, clusterId=null, type=null, correlationId=null, correlationIdString=null, replyTo=null, contentType=application/json, contentEncoding=UTF-8, contentLength=0, deliveryMode=null, receivedDeliveryMode=PERSISTENT, expiration=null, priority=0, redelivered=false, receivedExchange=test-mq-exchange, receivedRoutingKey=test_queue_routing_key, receivedDelay=null, deliveryTag=1, messageCount=0, consumerTag=amq.ctag-PSySAf57jb5fU99UgoG2kA, consumerQueue=test_queue_name])

　　12.浏览器中输入“http://localhost:15672/”，进入 Rabbit MQ的管理系统，查看 queue和exchange对应的相关信息如下。

三、Spring集成Rabbit MQ示例2

　　1.对MQ的生产者和消费者做了一些简单的封装，同一放到了一个工程下面里。无论是生产者还是消费者，只需要依赖上这个工程对应的jar就可以了。另外就是依赖上这个工程中MQ对应的XML文件。工程的基本结构如下所示。

　　2.XML文件如下。
