SpringBoot整合RabbitMQ之發(fā)布訂閱模式

更新時(shí)間：2025年06月12日 09:13:47 作者：新綠MEHO

本文主要介紹了SpringBoot整合RabbitMQ之發(fā)布訂閱模式,涵蓋依賴配置、隊(duì)列與交換機(jī)聲明綁定、生產(chǎn)者與雙消費(fèi)者代碼實(shí)現(xiàn),具有一定的參考價(jià)值,感興趣的可以了解一下

發(fā)布訂閱模式

引入依賴

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

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

添加配置

spring:
  application:
    name: rabbitmq-springboot
  rabbitmq:
    addresses: amqp://study:study@47.98.109.138:5672/aaa

常量類

public class Constants {

    //發(fā)布訂閱模式
    public static final String FANOUT_QUEUE1 = "fanout.queue1";
    public static final String FANOUT_QUEUE2 = "fanout.queue2";
    public static final String FANOUT_EXCHANGE = "fanout.exchange";
}

聲明隊(duì)列和交換機(jī)并綁定二者關(guān)系

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

@Configuration
public class RabbitMQConfig {

    @Bean("fanoutQueue1")
    public Queue fanoutQueue1(){
        return QueueBuilder.durable(Constants.FANOUT_QUEUE1).build();
    }

    @Bean("fanoutQueue2")
    public Queue fanoutQueue2(){
        return QueueBuilder.durable(Constants.FANOUT_QUEUE2).build();
    }
    @Bean("fanoutExchange")
    public FanoutExchange fanoutExchange(){
        return ExchangeBuilder.fanoutExchange(Constants.FANOUT_EXCHANGE).durable(true).build();
    }

    @Bean("fanoutQueueBinding1")
    public Binding fanoutQueueBinding1(@Qualifier("fanoutExchange") FanoutExchange fanoutExchange, @Qualifier("fanoutQueue1") Queue queue){
        return BindingBuilder.bind(queue).to(fanoutExchange);
    }
    @Bean("fanoutQueueBinding2")
    public Binding fanoutQueueBinding2(@Qualifier("fanoutExchange") FanoutExchange fanoutExchange, @Qualifier("fanoutQueue2") Queue queue){
        return BindingBuilder.bind(queue).to(fanoutExchange);
    }
}

編寫生產(chǎn)者代碼

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import rabbitmq.constant.Constants;

@RequestMapping("/producer")
@RestController
public class ProducerController {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @RequestMapping("/fanout")
    public String fanout(){
        rabbitTemplate.convertAndSend(Constants.FANOUT_EXCHANGE,"", "hello spring amqp:fanout...");
        return "發(fā)送成功";
    }
}

編寫消費(fèi)者代碼（含兩個(gè)隊(duì)列）

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import rabbitmq.constant.Constants;

@Component
public class FanoutListener {

    @RabbitListener(queues = Constants.FANOUT_QUEUE1)
    public void queueListener1(String message){
        System.out.println("隊(duì)列["+Constants.FANOUT_QUEUE1+"] 接收到消息:" +message);
    }

    @RabbitListener(queues = Constants.FANOUT_QUEUE2)
    public void queueListener2(String message){
        System.out.println("隊(duì)列["+Constants.FANOUT_QUEUE2+"] 接收到消息:" +message);
    }
}

生產(chǎn)消息

消費(fèi)消息

兩個(gè)隊(duì)列都收到并消費(fèi)了消息，且結(jié)果符合預(yù)期。
