本文详细介绍如何在SpringBoot项目中整合RabbitMQ，包括创建服务类、添加监听方法及配置启动类，实现消息接收与处理。通过示例代码展示如何在BookService类中接收来自RabbitMQ的消息。

1-新建service包BookService类

package com.example.springbootamqp.service;

import com.example.springbootamqp.bean.Book;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Service;

@Service
public class BookService {

    @RabbitListener(queues = "atguigu.news")
    public void receive(Book book){
        System.out.println("收到消息:"+book);
    }
}

2-启动类上添加注解@EnableRabbit

package com.example.springbootamqp;

import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableRabbit //开启基于注解的RabbitMQ模式
@SpringBootApplication
public class SpringbootRabbitmqAmqpApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootRabbitmqAmqpApplication.class, args);
    }

}

3-运行主程序类

Book类添加toString()方法

发送消息时,监听到消息

4-BookService中添加监听方法

import org.springframework.amqp.core.Message;

    @RabbitListener(queues = "atguigu")
    public void receive02(Message message){
        System.out.println(message.getBody());    //打印消息体
        System.out.println(message.getMessageProperties());     //打印消息头
    }
