SpringBoot集成RabbitMQ消息中间件

有了SpringBoot框架，我们开发RabbitMQ会十分便捷。

	首先需要引入pom文件：

		<!--引入rabbitmq 的springboot依赖，这个依赖需要在接收方和发送方同时引用-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-amqp</artifactId>
		</dependency>

	然后我们需要在配置文件加入  rabbitMq相关的配置信息，这个需要在发送方和接收方同时配置。

spring
   rabbitmq:
      host: 127.0.0.1
      port: 5672
      username: guest
      password: guest
      virtual-host: /

发送方：

	加入配置文件：

package org.jeecg.rabbitmq发送方.boot.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;



/**

 * @Email [email protected]
 * @date: 2021-12-16 17:14
 * @discription: mq 配置类
 **/
@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("botExchange")
    public Exchange  botExchange(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }



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



    //3.队列和交换的绑定
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue, @Qualifier("botExchange") Exchange exchange ){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }


}

	测试Controller：

package org.jeecg.rabbitmq发送方.boot;

import org.jeecg.rabbitmq发送方.boot.config.RabbitMQConfig;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

/**
 * @Author: xiaoduo
 * @Email [email protected]
 * @date: 2021-12-16 17:46
 * @discription: 测试
 **/
@RestController
@RequestMapping("/rabbitmq")
public class TestController {


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

    @GetMapping("/testSend")
    public String testSend(){

        rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","哈哈 今天 是2021-12-16");

        return "发送成功！";
    }


}

	开始测试:

接受方:

	接收方我们只用 监听消息后消费即可,代码相对较少.

package org.jeecg.rabbitmq接收方.boot;

import com.sun.org.apache.xpath.internal.operations.String;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * @Author: xiaoduo
 * @Email [email protected]
 * @date: 2021-12-16 17:59
 * @discription: rabbit 接收方
 **/
@Component
public class RabbitMQListener {

    @RabbitListener(queues = "boot_queue")
    public void ListenerQueue( Message  message){

        System.out.println(message);
    }

}

	当消费方发送消息他将自动接收并 消费。

消息接收成功。
