RabbitMQ安装和使用（和Spring集成）-阿里云开发者社区

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"

        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>
        </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"

    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" />
    <!--

    -->
    <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: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。

        }
        ((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};
