配置连接rabbitmq信息

#这几个参数 地址 端口号 账号 密码 虚拟机路径
rabbitmq.host=192.168.137.150
rabbitmq.port=5672
rabbitmq.username=admin
rabbitmq.password=123456
rabbitmq.virtual-host=/

spring配置文件 配置各种 交换机 绑定相关消息队列等

声明消息队列和交换机 并将交换机和消息队列绑定起来 也可以配置消息队列的监听器配置消息队列和交换机之间的路由key 通配符等信息

        </rabbit:bindings>

</beans> 

测试通过交换机向消息队列发送消息

那个交换机绑定的那些消息队列 配置文件里面都有

package com.atguigu.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@ContextConfiguration(locations = "classpath:/spring-rabbitmq.xml")
public class ProducerTest {

    @Autowired
    RabbitTemplate rabbitTemplate;


/**
配置向普通的消息队列发送消息
*/
    @Test
    public void testSimpleQueue(){
        rabbitTemplate.convertAndSend("spring_queue","spring info message");
    }


/**
向广播类型的交换机发送消息
*/
    @Test
    public void testFanout(){
        rabbitTemplate.convertAndSend("spring_fanout_exchange","","fanout info message");
    }


    /**
     * 通配符交换机
     * 交换机类型为 topic
     * 匹配路由键的通配符,*表示一个单词,#表示多个单词
     * 绑定到该交换机的匹配队列能够收到对应消息
     */
    @Test
    public void topicTest(){
        /**
         * 参数1：交换机名称
         * 参数2：路由键名
         * 参数3：发送的消息内容
         */
        rabbitTemplate.convertAndSend("spring_topic_exchange", "atguigu.bj", "发送到spring_topic_exchange交换机atguigu.bj的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "atguigu.bj.1", "发送到spring_topic_exchange交换机atguigu.bj.1的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "atguigu.bj.2", "发送到spring_topic_exchange交换机atguigu.bj.2的消息");
        rabbitTemplate.convertAndSend("spring_topic_exchange", "guigu.cn", "发送到spring_topic_exchange交换机guigu.cn的消息");
    }

}

测试 消费者监听并获取消息队列的信息

比如当前这个广播机的监听器 配置文件会配置这个监听器监听的时那个消息队列

package com.atguigu.rabbitmq.listener;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;

public class FanoutListener1 implements MessageListener {
    public void onMessage(Message message) {
        try {
            String msg = new String(message.getBody(), "utf-8");

            System.out.printf("1接收路由名称为：%s,路由键为：%s,队列名为：%s的消息：%s \n",
                    message.getMessageProperties().getReceivedExchange(),
                    message.getMessageProperties().getReceivedRoutingKey(),
                    message.getMessageProperties().getConsumerQueue(),
                    msg);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
