消息中间件-----Rabbitmq入门Demo

消息中间件三部曲:

开启服务器
配置文件
发送与接受

1, 生产者的Rabbitmq.xml配置

1.1 配置文件

<?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:rabbit="http://www.springframework.org/schema/rabbit"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
      http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
      http://www.springframework.org/schema/rabbit
      http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd">

    <!--配置connection-factory，指定连接rabbit server参数-->
    <rabbit:connection-factory id="connectionFactory" username="guest" password="guest"
                               host="localhost"
                               port="5672"
                               virtual-host="/"/>

    <!--通过指定下面的admin信息，当前producer中的exchange和queue会在rabbitmq服务器上自动生成-->
    <rabbit:admin connection-factory="connectionFactory"/>

    <!--定义queue-->
    <rabbit:queue id="com.mj.test" name="com.mj.test" durable="true" auto-delete="false" exclusive="false"/>

    <!-- 定义direct exchange，绑定com.mj.test queue -->
    <rabbit:direct-exchange name="myChange" durable="true" auto-delete="false">
        <rabbit:bindings>
            <rabbit:binding queue="com.mj.test" key="hello"></rabbit:binding>
        </rabbit:bindings>
    </rabbit:direct-exchange>
    
    <!--定义rabbit template用于数据的接收和发送-->
    <rabbit:template id="myAmqpTemplate" connection-factory="connectionFactory" exchange="myChange"/>
</beans>

1.2. 生产消息

@Service
public class MessageSender {

    @Resource(name="myAmqpTemplate")
    AmqpTemplate amqpTemplate;

    public void sendMessage(Object message){
        amqpTemplate.convertAndSend("hello",message);
    }
}

2, 消费消息

2.1 配置文件

<?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:rabbit="http://www.springframework.org/schema/rabbit"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
      http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
      http://www.springframework.org/schema/rabbit
      http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd">


    <rabbit:connection-factory id="connectionFactory" username="guest" password="guest"
                               host="localhost"
                               port="5672"
                               virtual-host="/"/>

    <rabbit:queue id="com.mj.test" name="com.mj.test" durable="true" auto-delete="false" exclusive="false"/>


    <bean id="messageReceiver" class="com.mj.amq.MessageReceiver"></bean>

    <rabbit:listener-container connection-factory="connectionFactory">
        <rabbit:listener queues="com.mj.test" ref="messageReceiver"/>
    </rabbit:listener-container>

</beans>

2.2 监听消息

public class MessageReceiver implements MessageListener {

    public void onMessage(Message message) {
        System.out.println(message);
    }

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