RabbitMQ —— spring标签整合实现

1.实现一个消息监听器ReceiveMessageListener

public class ReceiveMessageListener implements MessageListener  {
    public void onMessage(Message message) {
        System.out.println("msg:"+new String(message.getBody()));
    }
}

2. 消费者配置Consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"  
           xmlns:context="http://www.springframework.org/schema/context"

    <context:property-placeholder location="classpath:rabbitmq.properties"/>
  
    <!--配置connection-factory，指定连接rabbit server参数 -->
    <rabbit:connection-factory id="rabbitConnectionFactory" host="${rabbit.hosts}"
        username="${rabbit.username}" password="${rabbit.password}"

    <!--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 -->

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

        <rabbit:bindings>
            <rabbit:binding queue="spring.queue.tag" key="spring.queue.tag.key"></rabbit:binding>
        </rabbit:bindings>
    </rabbit:direct-exchange>
    
    <!-- amqp中MessageListener的实现类 -->
    <bean id="receiveMessageListener" class="test.spring.ReceiveMessageListener"></bean>
    
    <!-- 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="rabbitConnectionFactory" acknowledge="auto">
        <rabbit:listener queues="spring.queue.tag" ref="receiveMessageListener"/>
    </rabbit:listener-container>
</beans>

5. 生产者Producer

public class Producer {
    public static void main(String[] args) throws InterruptedException {  
        ApplicationContext context = new ClassPathXmlApplicationContext("spring/Producer.xml");  
        AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);  
        for(int i = 0;i < 10;i++) {
            User user = new User();  
            user.setId(i);
            user.setName("niuniu");  
            amqpTemplate.convertAndSend(user); 
            System.out.println("生产者发送完成:"+user.toString());
            Thread.sleep(2000);
        }
