RabbitMQ Java代码声明队列和交换机（方法一）

交换机和队列的声明一般写在消费者模块里

代码示例：

package com.itheima.config_RabbitMQ;

import org.springframework.amqp.core.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class FanoutConfiguration {
    @Bean
    public FanoutExchange fanoutExchange() { //创建交换机
        //方法一
        return ExchangeBuilder.fanoutExchange("hmall.fanout2").build();

        //方法二
        //return new FanoutExchange("hmall.fanout2");
    }

    @Bean
    public Queue fanoutQueue() { //创建队列
        //方法一
        return QueueBuilder.durable("fanout.queue3").build();

        //方法二
        //return new Queue("fanout.queue3");
    }

    @Bean
    public Queue fanoutQueue4() { //创建队列
        return QueueBuilder.durable("fanout.queue4").build();
    }

    @Bean
    public Binding fanoutBinding(Queue fanoutQueue, FanoutExchange fanoutExchange) { //绑定交换机、队列 方法一
        return BindingBuilder.bind(fanoutQueue).to(fanoutExchange);
    }

    @Bean
    public Binding fanoutBinding2() { //绑定交换机、队列 方法二
        return BindingBuilder.bind(fanoutQueue4()).to(fanoutExchange());
    }
}
