RabbitMq详细入门学习介绍二


相信你如果看过RabbitMq详细入门学习介绍一的5种消息队列模式是不是有点烦锁复杂。那么在这里,幸运的是,Spring提供了对rabbitMQ的封装,将复杂的关系设置整合到配置文件中。

依赖于两个组件,抽象层spring-amqp和实现层spring-rabbit。

于是代码简化为:

生产者:

public class SpringMain {
    public static void main(final String... args) throws Exception {
        AbstractApplicationContext ctx = new ClassPathXmlApplicationContext(
                "classpath:spring/rabbitmq-context.xml");
        //RabbitMQ模板
        RabbitTemplate template = ctx.getBean(RabbitTemplate.class);
        //发送消息
        template.convertAndSend("Hello, world!");
        Thread.sleep(1000);// 休眠1秒
        ctx.destroy(); //容器销毁
    }

}

消费者:

public class Foo {


    //具体执行业务的方法
    public void listen(String foo) {
        System.out.println("消费者: " + foo);
    }

}

spring-rabbitmq.xml的封装配置如下:

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit-1.4.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd">


<!--1 定义RabbitMQ的连接工厂 -->
<rabbit:connection-factory id="connectionFactory"
host="127.0.0.1" port="5672" username="learn" password="learn"
virtual-host="/mystore" />


<!--2 定义Rabbit模板,指定连接工厂以及定义exchange -->
<rabbit:template id="amqpTemplate" connection-factory="connectionFactory" exchange="fanoutExchange" />


<!-- MQ的管理,包括队列、交换器等 -->
<rabbit:admin connection-factory="connectionFactory" />


<!-- 定义队列,自动声明 -->
<rabbit:queue name="myQueue" auto-declare="true"/>

<!-- 3 定义交换器,自动声明 -->
<rabbit:fanout-exchange name="fanoutExchange" auto-declare="true">
<rabbit:bindings>
<rabbit:binding queue="myQueue"/>
</rabbit:bindings>
</rabbit:fanout-exchange>

<!-- 消费队列监听 -->
<rabbit:listener-container connection-factory="connectionFactory">
<rabbit:listener ref="foo" method="listen" queue-names="myQueue" />
</rabbit:listener-container>
<!--  消费者-->
<bean id="foo" class="com.learn.rabbitmq.spring.Foo" />


</beans>
