（转） RabbitMQ学习之spring整合发送异步消息

http://blog.csdn.net/zhu_tianwei/article/details/40919031

实现使用Exchange类型为DirectExchange. routingkey的名称默认为Queue的名称。异步发送消息。

1.配置文件

[plain] view plain copy
 
 print?
  1. #============== rabbitmq config ====================  
  2. rabbit.hosts=192.168.36.102  
  3. rabbit.username=admin  
  4. rabbit.password=admin  
  5. rabbit.virtualHost=/  
  6. rabbit.queue=spring-queue-async  
  7. rabbit.routingKey=spring-queue-async#<span style="font-family: Helvetica, Tahoma, Arial, sans-serif; font-size: 14px; line-height: 25.2000007629395px;">routingkey的名称默认为Queue的名称</span>  
2.生产者配置applicationContext-rabbitmq-async-send.xml：
[html] view plain copy
 
 print?
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <beans xmlns="http://www.springframework.org/schema/beans"  
  3.        xmlns:context="http://www.springframework.org/schema/context"  
  4.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  5.        xsi:schemaLocation="  
  6.         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
  7.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">  
  8.   
  9.     <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
  10.         <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />  
  11.         <property name="ignoreResourceNotFound" value="true" />  
  12.         <property name="locations">  
  13.             <list>  
  14.                 <!-- 标准配置 -->  
  15.                 <value>classpath*:/application.properties</value>  
  16.             </list>  
  17.         </property>  
  18.     </bean>  
  19.       
  20.     <!-- 创建connectionFactory -->  
  21.     <bean id="rabbitConnectionFactory"  
  22.       class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">  
  23.         <constructor-arg value="${rabbit.hosts}"/>  
  24.         <property name="username" value="${rabbit.username}"/>  
  25.         <property name="password" value="${rabbit.password}"/>  
  26.         <property name="virtualHost" value="${rabbit.virtualHost}"/>  
  27.         <property name="channelCacheSize" value="5"/>  
  28.     </bean>  
  29.       
  30.     <!-- 创建rabbitAdmin 代理类 -->  
  31.     <bean id="rabbitAdmin"  
  32.         class="org.springframework.amqp.rabbit.core.RabbitAdmin">  
  33.         <constructor-arg ref="rabbitConnectionFactory" />  
  34.     </bean>  
  35.       
  36.     <!-- 创建rabbitTemplate 消息模板类 
  37.      -->  
  38.     <bean id="rabbitTemplate"  
  39.         class="org.springframework.amqp.rabbit.core.RabbitTemplate">  
  40.         <constructor-arg ref="rabbitConnectionFactory"></constructor-arg>  
  41.         <property name="routingKey" value="${rabbit.routingKey}"></property>  
  42.     </bean>  
  43. </beans>  
3.生产者发送消息代码Send.java
[java] view plain copy
 
 print?
  1. package cn.slimsmart.rabbitmq.demo.spring.async;  
  2.   
  3. import org.springframework.amqp.core.AmqpTemplate;  
  4. import org.springframework.amqp.rabbit.core.RabbitTemplate;  
  5. import org.springframework.context.ApplicationContext;  
  6. import org.springframework.context.support.ClassPathXmlApplicationContext;  
  7.   
  8. public class Send {  
  9.   
  10.     public static void main(String[] args) throws InterruptedException {  
  11.         ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-send.xml");    
  12.         AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);    
  13.         for(int i=0;i<1000;i++){  
  14.             amqpTemplate.convertAndSend("test spring async=>"+i);   
  15.             Thread.sleep(3000);  
  16.         }  
  17.     }  
  18. }  

4.处理消息类ReceiveMsgHandler.Java

[java] view plain copy
 
 print?
  1. package cn.slimsmart.rabbitmq.demo.spring.async;  
  2.   
  3. public class ReceiveMsgHandler {  
  4.   
  5.     public void handleMessage(String text) {  
  6.         System.out.println("Received: " + text);  
  7.     }  
  8. }  
5.配置applicationContext-rabbitmq-async-receive.xml：
[html] view plain copy
 
 print?
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <beans xmlns="http://www.springframework.org/schema/beans"  
  3.        xmlns:context="http://www.springframework.org/schema/context"  
  4.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  5.        xsi:schemaLocation="  
  6.         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
  7.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">  
  8.      
  9.     <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
  10.         <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />  
  11.         <property name="ignoreResourceNotFound" value="true" />  
  12.         <property name="locations">  
  13.             <list>  
  14.                 <!-- 标准配置 -->  
  15.                 <value>classpath*:/application.properties</value>  
  16.             </list>  
  17.         </property>  
  18.     </bean>  
  19.       
  20.     <!-- 创建connectionFactory -->  
  21.     <bean id="rabbitConnectionFactory"  
  22.       class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">  
  23.         <constructor-arg value="${rabbit.hosts}"/>  
  24.         <property name="username" value="${rabbit.username}"/>  
  25.         <property name="password" value="${rabbit.password}"/>  
  26.         <property name="virtualHost" value="${rabbit.virtualHost}"/>  
  27.         <property name="channelCacheSize" value="5"/>  
  28.     </bean>  
  29.       
  30.     <!-- 声明消息转换器为SimpleMessageConverter -->    
  31.     <bean id="messageConverter"    
  32.         class="org.springframework.amqp.support.converter.SimpleMessageConverter">    
  33.     </bean>    
  34.     <!-- 监听生产者发送的消息开始 -->    
  35.     <!-- 用于接收消息的处理类 -->    
  36.     <bean id="receiveHandler"    
  37.         class="cn.slimsmart.rabbitmq.demo.spring.async.ReceiveMsgHandler">    
  38.     </bean>    
  39.     <!-- 用于消息的监听的代理类MessageListenerAdapter -->    
  40.     <bean id="receiveListenerAdapter"    
  41.         class="org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter">    
  42.         <constructor-arg ref="receiveHandler" />    
  43.         <property name="defaultListenerMethod" value="handleMessage"></property>    
  44.         <property name="messageConverter" ref="messageConverter"></property>    
  45.     </bean>    
  46.     <!-- 用于消息的监听的容器类SimpleMessageListenerContainer，对于queueName的值一定要与定义的Queue的值相同 -->    
  47.     <bean id="listenerContainer"    
  48.         class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer">    
  49.         <property name="queueNames" value="${rabbit.queue}"></property>   
  50.         <property name="connectionFactory" ref="rabbitConnectionFactory"></property>    
  51.         <property name="messageListener" ref="receiveListenerAdapter"></property>    
  52.     </bean>    
  53.     <!-- 监听生产者发送的消息结束 -->    
  54. </beans>  
5.接收消息启动类Receive.java
[java] view plain copy
 
 print?
  1. package cn.slimsmart.rabbitmq.demo.spring.async;  
  2.   
  3. import org.springframework.context.support.ClassPathXmlApplicationContext;  
  4.   
  5. public class Receive {  
  6.   
  7.     public static void main(String[] args) {  
  8.          new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-receive.xml");  
  9.     }  
  10. }  
启动接收消息，再发送消息
[plain] view plain copy
 
 print?
  1. Received: test spring async=>0  
  2. Received: test spring async=>1  
  3. Received: test spring async=>2  
  4. Received: test spring async=>3  
  5. Received: test spring async=>4  
  6. Received: test spring async=>5  
  7. Received: test spring async=>6  
  8. Received: test spring async=>7  
  9. ......  
若报如下错误，说明消息队列不存在，请在控制台添加消息队列。
