大菜菜学习RabbitMQ——第八篇

本篇文章主要讲如何用java代码创建队列和交换机，或者说是声明

 我们都是在消费者这边进行声明

所以我们开始写代码

 我们先创建这么个文件

package com.itheima.consumer.config;

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() {
//        ExchangeBuilder.fanoutExchange("").build(); //这里也可以这么写
        return new FanoutExchange("hmall.fanout2");
    }

    @Bean
    public Queue fanoutQueue3() {
//        QueueBuilder.durable("").build(); //这里的durable是持久的意思
        return new Queue("fanout.queue3");
    }

    @Bean
    public Binding fanoutBinding3(Queue fanoutQueue3 , FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanoutQueue3).to(fanoutExchange);
    }

    @Bean
    public Queue fanoutQueue4() {
//        QueueBuilder.durable("").build(); //这里的durable是持久的意思
        return new Queue("fanout.queue4");
    }

    @Bean
    public Binding fanoutBinding4() {
        return BindingBuilder.bind(fanoutQueue4()).to(fanoutExchange());
    }
}

只要我们一运行我们就可以看到

 但这个只是fanout，如果我们是direct呢

所以我们在同目录下面创建文件

package com.itheima.consumer.config;

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

/**
 * 功能：
 * 作者：LiCooer
 * 日期：2024/4/9 14:52
 */
@Configuration
public class DirectConfiguration {

    @Bean
    public DirectExchange directExchange() {
//        ExchangeBuilder.fanoutExchange("").build(); //这里也可以这么写
        return new DirectExchange("hmall.direct1");
    }

    @Bean
    public Queue directQueue3() {
//        QueueBuilder.durable("").build(); //这里的durable是持久的意思
        return new Queue("direct.queue3");
    }

    @Bean
    public Binding directQueue3BindingRed(Queue directQueue3 , DirectExchange directExchange) {
        return BindingBuilder.bind(directQueue3).to(directExchange).with("red");
    }

    @Bean
    public Binding directQueue3BindingBlue(Queue directQueue3 , DirectExchange directExchange) {
        return BindingBuilder.bind(directQueue3).to(directExchange).with("blue");
    }

    @Bean
    public Queue directQueue4() {
//        QueueBuilder.durable("").build(); //这里的durable是持久的意思
        return new Queue("direct.queue4");
    }

    @Bean
    public Binding directQueue4BindingRed(Queue directQueue4 , DirectExchange directExchange) {
        return BindingBuilder.bind(directQueue4).to(directExchange).with("red");
    }

    @Bean
    public Binding directQueue4BindingBrown(Queue directQueue4 , DirectExchange directExchange) {
        return BindingBuilder.bind(directQueue4).to(directExchange).with("brown");
    }
}

交换机还有队列就不多赘述了

 很显然，很麻烦，所以祝贺各位变成白学公主
