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：

  1. 下载并安装 Eralng OTP For Windows (vR16B03)
  2. 运行安装 Rabbit MQ Server Windows Installer (v3.2.3)
  3. 具体操作步骤参考：在 Windows 上安装Rabbit MQ 指南
  4. 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>
View Code

　　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"

        http://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">

            </list>
        </property>
    </bean>
    
    <context:component-scan base-package="com.hjz.rabbit" />
</beans>
View Code

　　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"

    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">
     
    <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

        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" />
    
    <!--

        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

    -->
    <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 {
    
    @Autowired
    private AmqpTemplate amqpTemplate;
    
    @Override
    public 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 {

    @Override
    public 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{
    @Autowired
    private MQSender mqSender;

    final String queueName = "test_queue_routing_key";

    @Test
    public 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。

//    private ServletContext application = ContextLoader.getCurrentWebApplicationContext().getServletContext();
    
    @SuppressWarnings("unchecked")
    @Override
    protected void doConsumeMsg(MqMessage mqMessage) {
        if(application.getAttribute("MQ_MESSAGE") == null) {

        }
        ((List<Object>)application.getAttribute("MQ_MESSAGE")).add(mqMessage.getBody());
    }

    @Override
    protected String[] getQueueNames() {
        return new String[] {MqConfig.MQ_QUEUE_ADD, MqConfig.MQ_QUEUE_SAVE, MqConfig.MQ_QUEUE_UPDATE};
