1. 创建 SpringBoot 工程

由于有的 Idea 不选择插线无法创建 Spring Boot 项目，这里我们先随便选一个插件，大家也可以根据需求选择~~

把版本改为 2.7.14

引入这两个依赖:

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-amqp</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>

配置 application.yml文件

2. 编写代码

生产者 :

Config 类 : RabbitMQConfig

SpringBoot 整合 RabbitMQ,spring boot,java-rabbitmq,rabbitmq

package com.lqf.rabbitmq.springbootrabbitmq.config;

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

@Configuration
public class RabbitMQConfig {

    public static final String EXCHANGE_NAME = "boot_topic_exchange";
    public static final String QUEUE_NAME = "boot_queue";

    //1.交换机
    @Bean("bootExchange")
    public Exchange bootExchange(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }


    //2.Queue 队列
    @Bean("bootQueue")
    public Queue bootQueue(){
        return QueueBuilder.durable(QUEUE_NAME).build();
    }

    //3. 队列和交互机绑定关系 Binding
    /*
        1. 知道哪个队列
        2. 知道哪个交换机
        3. routing key
     */
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue, @Qualifier("bootExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }


}

测试类: RabbitMQConfigTests

package com.lqf.rabbitmq.springbootrabbitmq;

import com.lqf.rabbitmq.springbootrabbitmq.config.RabbitMQConfig;
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.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
@RunWith(SpringRunner.class)
public class RabbitMQConfigTests {

    //1.注入RabbitTemplate
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testSend(){

        rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","boot mq hello~~~");
    }
}

结果

当我们启动测试类之后就可以发现我们的 rabbitmq 界面里的 Exchange 里多了一个

Queue 中多了一个消息:

消费者:

消费者的创建与生产者一样

Component 类 :

package com.example.rabbitmq;

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

@Component
public class RabbitMQListener {
    
    @RabbitListener(queues = "boot_queue")
    public void ListenerQueue(Message message) {
        System.out.println("Message : ");
        System.out.println(message);
    }
}
