配置文件：

MyRabbitConfig

package org.example.config;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MyRabbitConfig
{

    public final static String FANOUT_NAME ="amqp-fanout";

    @Bean
    FanoutExchange fanoutExchange(){
        return new FanoutExchange(FANOUT_NAME,true,false);
    }

    @Bean
    Queue queueOne(){
        return new Queue("queue-one");
    }

    @Bean
    Queue queueTwo(){
        return new Queue("queue-two");
    }

    @Bean
    Binding bindingOne(){
        return BindingBuilder.bind(queueOne()).to(fanoutExchange());
    }

    @Bean
    Binding bindingTwo(){
        return BindingBuilder.bind(queueTwo()).to(fanoutExchange());
    }

}

监听-接收消息：

FanoutReceiver

package org.example.receiver;

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * 配置消费者
 * 两个消费者分别监听两个不同的队列
 */
@Component
public class FanoutReceiver {

    @RabbitListener(queues = "queue-one")
    public void handler1(String msg)
    {

        System.out.println("第一个队列>>>"+msg);

    }

    @RabbitListener(queues = "queue-two")
    public void handler2(String msg)
    {

        System.out.println("第二个队列>>>"+msg);


    }
