RabbitMQ学习之spring配置文件rabbit标签的使用

下面我们通过一个实例看一下rabbit的使用。

1.实现一个消息监听器ReceiveMessageListener.Java

 

package org.springframework.amqp.core;

/**
 * Listener interface to receive asynchronous delivery of Amqp Messages.
 *
 * @author Mark Pollack
 */
public interface MessageListener {

    void onMessage(Message message);

}

2.消费者配置Consumer.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"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:rabbit="http://www.springframework.org/schema/rabbit"
       xsi:schemaLocation="
            http://www.springframework.org/schema/beans
                http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context
                http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/rabbit
                http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd">

   <!-- 连接服务配置  -->
    <rabbit:connection-factory id="connectionFactory" host="192.168.36.102" username="admin"
        password="admin" port="5672" virtual-host="/"  channel-cache-size="5" />

   <rabbit:admin connection-factory="connectionFactory"/>

   <!-- queue 队列声明-->
   <rabbit:queue durable="true" auto-delete="false" exclusive="false" name="spring.queue.tag"/>


   <!-- exchange queue binging key 绑定 -->
    <rabbit:direct-exchange name="spring.queue.exchange" durable="true" auto-delete="false">
        <rabbit:bindings>
            <rabbit:binding queue="spring.queue.tag" key="spring.queue.tag.key"/>
        </rabbit:bindings>
    </rabbit:direct-exchange>

    <bean id="receiveMessageListener"
        class="cn.slimsmart.rabbitmq.demo.spring.tag.ReceiveMessageListener" />

    <!-- queue litener  观察 监听模式 当有消息到达时会通知监听在对应的队列上的监听对象-->
    <rabbit:listener-container connection-factory="connectionFactory" acknowledge="auto" >
        <rabbit:listener queues="spring.queue.tag" ref="receiveMessageListener" />
    </rabbit:listener-container>
</beans>

3.生产者配置Producer.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" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:rabbit="http://www.springframework.org/schema/rabbit"
    xsi:schemaLocation="
            http://www.springframework.org/schema/beans
                http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context
                http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/rabbit
                http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd">

    <!-- 连接服务配置 -->
    <rabbit:connection-factory id="connectionFactory"
        host="192.168.36.102" username="admin" password="admin" port="5672"
        virtual-host="/" channel-cache-size="5" />

    <rabbit:admin connection-factory="connectionFactory" />

    <!-- queue 队列声明 -->
    <rabbit:queue  durable="true"
        auto-delete="false" exclusive="false" name="spring.queue.tag" />


    <!-- exchange queue binging key 绑定 -->
    <rabbit:direct-exchange name="spring.queue.exchange"
        durable="true" auto-delete="false">
        <rabbit:bindings>
            <rabbit:binding queue="spring.queue.tag" key="spring.queue.tag.key" />
        </rabbit:bindings>
    </rabbit:direct-exchange>

    <!-- spring amqp默认的是jackson 的一个插件,目的将生产者生产的数据转换为json存入消息队列，由于Gson的速度快于jackson,这里替换为Gson的一个实现 -->
    <bean id="jsonMessageConverter"
        class="cn.slimsmart.rabbitmq.demo.spring.tag.Gson2JsonMessageConverter" />

    <!-- spring template声明 -->
    <rabbit:template id="amqpTemplate" exchange="spring.queue.exchange"  routing-key="spring.queue.tag.key"
        connection-factory="connectionFactory" message-converter="jsonMessageConverter" />
</beans>

4.消费者启动类ConsumerMain.java

 

 

package cn.slimsmart.rabbitmq.demo.spring.tag;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ConsumerMain {

    public static void main(String[] args) {
        new ClassPathXmlApplicationContext("Consumer.xml");
    }
}

5.生产者启动类ProducerMain.java

 

 

package cn.slimsmart.rabbitmq.demo.spring.tag;

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 ProducerMain {

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("Producer.xml");
        AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);
        User user = new User();
        user.setName("niuniu");
        amqpTemplate.convertAndSend(user);
    }
}

先启动消费者，监听接收消息，再启动生产者发送消息。

 

输出： data :{"name":"niuniu"}

如下4中转发器类型标签

rabbit:fanout-exchange

rabbit:direct-exchange

rabbit:topic-exchange

rabbit:headers-exchange
