MQ全称为Message Queue, （MQ）是一种应用程序对应用程序的通信方法。应用程序通过读写出入队列的消息（针对应用程序的数据）来通信，而无需专用连接来链接它们。消息传递指的是程序之间通过在消息中发送数据进行通信，而不是通过直接调用彼此来通信，直接调用通常是用于诸如的技术。排队指的是应用程序通过 队列来通信。队列的使用除去了接收和发送应用程序同时执行的要求..

开始正题!

在开发之前需要下载rabbitmq, 而在rabbitmq安装之前,童鞋们需要安装erlang, 因为rabbitmq是用erlang写的.

安装完毕之后,我们建立一个maven项目.然后我们开始配置项目.

46.  
    <artifactId>spring-web</artifactId>
47.  
    <version>${spring.version}</version>
48.  
    </dependency>

由于是spring整合,我们需要加入spring的依赖.

1.  
   <!--rabbitmq依赖 -->
2.  
   <dependency>
3.  
   <groupId>org.springframework.amqp</groupId>
4.  
   <artifactId>spring-rabbit</artifactId>
5.  
   <version>1.3.5.RELEASE</version>
6.  
   </dependency>

依赖加好了之后, 我们需要定义消息生产者和消息发送者.

由于exchange有几种,这里我只测试了两种, 通过分别定义两个exchange去绑定direct和topic..

首先, 定义消息生产者, 通过配置将template链接connect-factory并注入到代码中使用.

1.  
   package com.chris.producer;
2.  
    
3.  
   import org.slf4j.Logger;
4.  
   import org.slf4j.LoggerFactory;
5.  
   import org.springframework.amqp.core.AmqpTemplate;
6.  
   import org.springframework.stereotype.Service;
7.  
    
8.  
   import javax.annotation.Resource;
9.  
   import java.io.IOException;
10.  
     
11.  
    /**
12.  
    * Created by wuxing on 2016/9/21.
13.  
    */
14.  
    @

    Service
15.  
    public class MessageProducer {
16.  
     
17.  
    private Logger logger = LoggerFactory.getLogger(MessageProducer.class);
18.  
     
19.  
    @

    Resource(name="amqpTemplate")
20.  
    private AmqpTemplate amqpTemplate;
21.  
     
22.  
    @

    Resource(name="amqpTemplate2")
23.  
    private AmqpTemplate amqpTemplate2;
24.  
     
25.  
    public void sendMessage(Object message) throws IOException {
26.  
    logger.info(

    "to send message:{}", message);
27.  
    amqpTemplate.convertAndSend(

    "queueTestKey", message);
28.  
    amqpTemplate.convertAndSend(

    "queueTestChris", message);
29.  
     
30.  
    amqpTemplate2.convertAndSend(

    "wuxing.xxxx.wsdwd", message);
31.  
    }
32.  
    }

然后我们定义消息消费者, 这里,我定义了三个消费者, 通过监听消息队列, 分别接受各自所匹配的消息.

第一个消费者, 接受direct的消息, 他的exchange为exchangeTest,  rout-key为queueTestKey

1.  
   package com.chris.consumer;
2.  
    
3.  
   import org.slf4j.Logger;
4.  
   import org.slf4j.LoggerFactory;
5.  
   import org.springframework.amqp.core.Message;
6.  
   import org.springframework.amqp.core.MessageListener;
7.  
    
8.  
   /**
9.  
   * Created by wuxing on 2016/9/21.
10.  
    */
11.  
    public class MessageConsumer implements MessageListener {
12.  
     
13.  
    private Logger logger = LoggerFactory.getLogger(MessageConsumer.class);
14.  
     
15.  
    @Override
16.  
    public void onMessage(Message message) {
17.  
    logger.info(

    "consumer receive message------->:{}", message);
18.  
    }
19.  
     
20.  
    }

第二个消费者, 接受direct的消息(为了测试一个exchange可以发送多个消息), 他的exchange为exchangeTest,  rout-key为queueTestChris.

1.  
   package com.chris.consumer;
2.  
    
3.  
   import org.slf4j.Logger;
4.  
   import org.slf4j.LoggerFactory;
5.  
   import org.springframework.amqp.core.Message;
6.  
   import org.springframework.amqp.core.MessageListener;
7.  
    
8.  
   /**
9.  
   * Created by wuxing on 2016/9/21.
10.  
    */
11.  
    public class ChrisConsumer implements MessageListener {
12.  
    private Logger logger = LoggerFactory.getLogger(ChrisConsumer.class);
13.  
     
14.  
    @Override
15.  
    public void onMessage(Message message) {
16.  
    logger.info(

    "chris receive message------->:{}", message);
17.  
    }
18.  
    }

第三个消费者, 接受topic的消息他的exchange为exchangeTest2,  pattern为wuxing.*.. 网上说.*可以匹配一个, .#可以匹配一个或多个..但是笔者好像两个都试了..都可以匹配一个或多个..不知道什么鬼...

1.  
    
2.  
   package com.chris.consumer;
3.  
    
4.  
   import org.slf4j.Logger;
5.  
   import org.slf4j.LoggerFactory;
6.  
   import org.springframework.amqp.core.Message;
7.  
   import org.springframework.amqp.core.MessageListener;
8.  
    
9.  
   /**
10.  
    * Created by wuxing on 2016/9/21.
11.  
    */
12.  
    public class WuxingConsumer implements MessageListener {
13.  
    private Logger logger = LoggerFactory.getLogger(WuxingConsumer.class);
14.  
     
15.  
    @Override
16.  
    public void onMessage(Message message) {
17.  
    logger.info(

    "wuxing receive message------->:{}", message);
18.  
    }
19.  
    }

然后就是关键的地方了..rabbit整合spring的配置文件.

85.  
    </beans>

 

这里,有个问题笔者研究了好久...就是如何定义两个exchange, 一开始一直不成功..直到找到了一篇国外的文章才解决...

定义两个exchange的时候, 需要用到declared-by..

而这个必须要引入下面的这个申明, 才有..

1.  
   http:

   //www.springframework.org/schema/rabbit
2.  
   http:

   //www.springframework.org/schema/rabbit/spring-rabbit-1.2.xsd">

 

文件中大概的配置解释一下.

connect-factory进行连接rabbitmq服务.

template用于连接factory并指定exchange, 这上面还能直接指定rout-key.

admin相当于一个管理员的角色..可以将exchange和queue进行管理, 

queue和topic-exchange分别定义队列和路由器, 这里需要用declared-by指定管理员,从而连接到相应的factory.

listener-container用于消费者的监听(其实,rabbit配置中是可以指定某个类的某个方法的, 但是笔者失败了, 还在试验中...)

这里还有一个问题...需要大家注意..

当一个exchange绑定了一种类型之后, 这个exchange在配置就不能再换成另一种了.会一直报错, received 'direct' but current is 'topic'  类似这种..

笔者这个也是被坑了若干时间去找问题...

 

然后贴下spring的基本配置

1.  
   <?xml version="1.0" encoding="UTF-8"?>
2.  
   <beans xmlns="http://www.springframework.org/schema/beans"
3.  
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
4.  
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
5.  
   http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
6.  
    
7.  
   <import resource="classpath*:rabbitmq.xml" />
8.  
    
9.  
   <!-- 扫描指定package下所有带有如@controller,@services,@resource,@ods并把所注释的注册为Spring Beans -->
10.  
    <context:component-scan base-package="com.chris.consumer, com.chris.producer" />
11.  
     
12.  
    <!-- 激活annotation功能 -->
13.  
    <context:annotation-config />
14.  
    <!-- 激活annotation功能 -->
15.  
    <context:spring-configured />
16.  
     
17.  
    </beans>

 

然后是单元测试类, 这里通过输出100-1慢慢递减,去观察控制台消费者接收消息的情况.

1.  
   package com.chris;
2.  
    
3.  
   import com.chris.producer.MessageProducer;
4.  
   import org.junit.Before;
5.  
   import org.junit.Test;
6.  
   import org.slf4j.Logger;
7.  
   import org.slf4j.LoggerFactory;
8.  
   import org.springframework.context.ApplicationContext;
9.  
   import org.springframework.context.support.ClassPathXmlApplicationContext;
10.  
     
11.  
    /**
12.  
    * Created by wuxing on 2016/9/21.
13.  
    */
14.  
    public class MessageTest {
15.  
     
16.  
    private Logger logger = LoggerFactory.getLogger(MessageTest.class);
17.  
     
18.  
    private ApplicationContext context = null;
19.  
     
20.  
    @Before
21.  
    public void setUp() throws Exception {
22.  
    context =

    new ClassPathXmlApplicationContext("application.xml");
23.  
    }
24.  
     
25.  
    @Test
26.  
    public void should_send_a_amq_message() throws Exception {
27.  
    MessageProducer messageProducer = (MessageProducer) context.getBean(

    "messageProducer");
28.  
    int a = 100;
29.  
    while (a > 0) {
30.  
    messageProducer.sendMessage(

    "Hello, I am amq sender num :" + a--);
31.  
    try {
32.  
    //暂停一下，好让消息消费者去取消息打印出来
33.  
    Thread.sleep(

    1000);
34.  
    }

    catch (InterruptedException e) {
35.  
    e.printStackTrace();
36.  
    }
37.  
     
38.  
    }
39.  
    }
40.  
    }

然后控制台的结果如下(这里只贴出关键信息, 其他配置的log的省略了)

我们可以看到生产者有发出一个信息, 然后发布在了三个通道上.

 

1. on exchange [exchangeTest] , routingKey = [queueTestKey]

2. on exchange [exchangeTest] , routingKey = [queueTestChris]

3. on exchange [exchangeTest2] , routingKey = [wuxing.xxxx.wsdwd]

 

然后三个消费者分别收到了他们的消息..至此, 整个test就结束了.

对项目有兴趣的童鞋可以拿项目的源码玩一玩
