（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

#============== 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：

<?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

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

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：

<?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

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

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。

控制台添加队列。
