　连接工具类：

package com.toov5.utils;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
 
//没有做成单例的  VirtualHost 需要复用
public class MQConnectionUtils {
    //创建新的连接
    public static Connection newConnection() throws IOException, TimeoutException {
         //创建连接工厂
    ConnectionFactory factory= new ConnectionFactory();
    //链接地址
    factory.setHost("192.168.91.6");
    //用户名称
    factory.setUsername("admin");
    //用户密码
    factory.setPassword("admin");
    //amqp端口号
    factory.setPort(5672);
    //连接virtualhost
    factory.setVirtualHost("/admin_toov5");
    Connection connection = factory.newConnection();
        return connection;
    }    
}

生产者：

package com.toov5.fanout;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.toov5.utils.MQConnectionUtils;

//生产者 交换机类型 producerFanout类型
public class FanoutProducer {
    //交换机名称
     private static final String EXCHANGE_NAME = "my_fanout"; 
     public static void main(String[] args) throws IOException, TimeoutException {
        //建立MQ连接
         Connection connection = MQConnectionUtils.newConnection();
        //创建通道
          Channel channel = connection.createChannel();
          //生产者绑定交换机
          channel.exchangeDeclare(EXCHANGE_NAME, "fanout");  //交换机名称  交换机类型
          //创建对应的消息 
          String msString = "my_fanout_destination_msg";
          //通过频道 发送消息
          System.out.println("生产者投递消息："+msString);
          channel.basicPublish(EXCHANGE_NAME, "", null, msString.getBytes());
          //关闭通道 和 连接
          channel.close();
          connection.close();
    }
    
}

         System.out.println("邮件消费者启动");
        //建立MQ连接
         Connection connection = MQConnectionUtils.newConnection();
        //创建通道
          Channel channel = connection.createChannel();
          
       //消费者声明队列
          channel.queueDeclare(EMAIL_QUEUE, false, false, false, null);
         //消费者队列绑定交换机
          channel.queueBind(EMAIL_QUEUE, EXCHANGE_NAME, "");
          //消费者监听消息
      DefaultConsumer defaultConsumer =     new DefaultConsumer(channel) {
              //重写监听方法
             @Override
             public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties, byte[] body)
                     throws IOException {

                 System.out.println("邮件消费者获取生产者消息"+msg);
             }
         };
         channel.basicConsume(EMAIL_QUEUE,true, defaultConsumer);   //绑定队列 事件监听
            
    }
