RabbitMQ学习(十一)之spring整合发送异步消息

2016-07-15 16:01 585 查看
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?





#============== rabbitmq config ====================  
rabbit.hosts=192.168.36.102  
rabbit.username=admin  
rabbit.password=admin  
rabbit.virtualHost=/  
rabbit.queue=spring-queue-async  
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?





<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
       xmlns:context="http://www.springframework.org/schema/context"  
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
       xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">  
  
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
        <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />  
        <property name="ignoreResourceNotFound" value="true" />  
        <property name="locations">  
            <list>  
                <!-- 标准配置 -->  
                <value>classpath*:/application.properties</value>  
            </list>  
        </property>  
    </bean>  
      
    <!-- 创建connectionFactory -->  
    <bean id="rabbitConnectionFactory"  
      class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">  
        <constructor-arg value="${rabbit.hosts}"/>  
        <property name="username" value="${rabbit.username}"/>  
        <property name="password" value="${rabbit.password}"/>  
        <property name="virtualHost" value="${rabbit.virtualHost}"/>  
        <property name="channelCacheSize" value="5"/>  
    </bean>  
      
    <!-- 创建rabbitAdmin 代理类 -->  
    <bean id="rabbitAdmin"  
        class="org.springframework.amqp.rabbit.core.RabbitAdmin">  
        <constructor-arg ref="rabbitConnectionFactory" />  
    </bean>  
      
    <!-- 创建rabbitTemplate 消息模板类 
     -->  
    <bean id="rabbitTemplate"  
        class="org.springframework.amqp.rabbit.core.RabbitTemplate">  
        <constructor-arg ref="rabbitConnectionFactory"></constructor-arg>  
        <property name="routingKey" value="${rabbit.routingKey}"></property>  
    </bean>  
</beans>  

3.生产者发送消息代码Send.java

[java]
view plain
copy
print?





package cn.slimsmart.rabbitmq.demo.spring.async;  
  
import org.springframework.amqp.core.AmqpTemplate;  
import org.springframework.amqp.rabbit.core.RabbitTemplate;  
import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
  
public class Send {  
  
    public static void main(String[] args) throws InterruptedException {  
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-send.xml");    
        AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);    
        for(int i=0;i<1000;i++){  
            amqpTemplate.convertAndSend("test spring async=>"+i);   
            Thread.sleep(3000);  
        }  
    }  
}  

4.处理消息类ReceiveMsgHandler.Java

[java]
view plain
copy
print?





package cn.slimsmart.rabbitmq.demo.spring.async;  
  
public class ReceiveMsgHandler {  
  
    public void handleMessage(String text) {  
        System.out.println("Received: " + text);  
    }  
}  

5.配置applicationContext-rabbitmq-async-receive.xml:

[html]
view plain
copy
print?





<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
       xmlns:context="http://www.springframework.org/schema/context"  
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
       xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">  
     
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
        <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />  
        <property name="ignoreResourceNotFound" value="true" />  
        <property name="locations">  
            <list>  
                <!-- 标准配置 -->  
                <value>classpath*:/application.properties</value>  
            </list>  
        </property>  
    </bean>  
      
    <!-- 创建connectionFactory -->  
    <bean id="rabbitConnectionFactory"  
      class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">  
        <constructor-arg value="${rabbit.hosts}"/>  
        <property name="username" value="${rabbit.username}"/>  
        <property name="password" value="${rabbit.password}"/>  
        <property name="virtualHost" value="${rabbit.virtualHost}"/>  
        <property name="channelCacheSize" value="5"/>  
    </bean>  
      
    <!-- 声明消息转换器为SimpleMessageConverter -->    
    <bean id="messageConverter"    
        class="org.springframework.amqp.support.converter.SimpleMessageConverter">    
    </bean>    
    <!-- 监听生产者发送的消息开始 -->    
    <!-- 用于接收消息的处理类 -->    
    <bean id="receiveHandler"    
        class="cn.slimsmart.rabbitmq.demo.spring.async.ReceiveMsgHandler">    
    </bean>    
    <!-- 用于消息的监听的代理类MessageListenerAdapter -->    
    <bean id="receiveListenerAdapter"    
        class="org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter">    
        <constructor-arg ref="receiveHandler" />    
        <property name="defaultListenerMethod" value="handleMessage"></property>    
        <property name="messageConverter" ref="messageConverter"></property>    
    </bean>    
    <!-- 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 -->    
    <bean id="listenerContainer"    
        class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer">    
        <property name="queueNames" value="${rabbit.queue}"></property>   
        <property name="connectionFactory" ref="rabbitConnectionFactory"></property>    
        <property name="messageListener" ref="receiveListenerAdapter"></property>    
    </bean>    
    <!-- 监听生产者发送的消息结束 -->    
</beans>  

5.接收消息启动类Receive.java

[java]
view plain
copy
print?





package cn.slimsmart.rabbitmq.demo.spring.async;  
  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
  
public class Receive {  
  
    public static void main(String[] args) {  
         new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-receive.xml");  
    }  
}  

启动接收消息,再发送消息

[plain]
view plain
copy
print?





Received: test spring async=>0  
Received: test spring async=>1  
Received: test spring async=>2  
Received: test spring async=>3  
Received: test spring async=>4  
Received: test spring async=>5  
Received: test spring async=>6  
Received: test spring async=>7  
......  

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。

[java]
view plain
copy
print?

控制台添加队列。
