springBoot整合RabbitMQ

1、工程结构

2、创建生产者工程

工程名：springboot-rabbitmq-producer

2.1 引入以下依赖

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

2.2 编写application.properties

# 应用名称
spring.application.name=springboot-rabbitmq-producer
# 应用服务 WEB 访问端口
server.port=8080
#RabbitMQ配置
spring.rabbitmq.virtual-host=/
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

2.3 编写RabbitMQConfig

package com.cn.fb.config;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @className: RabbitMQConfig
 * @Description: RabbitMQConfig
 * @Author: liangyongyong
 * @Date: 2022/3/23 20:43
 * @Version: 1.0.0
 */
@Configuration
public class RabbitMQConfig {

    /**
     * 交换机名称
     */
    private static final String ITEM_DIRECT_EXCHANGE = "itemDirectExchange";
    /**
     * 队列名称
     */
    private static final String ITEM_QUEUE = "itemQueue";

    /**
     * 声明交换机
     *
     * @return
     */
    @Bean("itemDirectExchange")
    public DirectExchange itemDirectExchange() {
        return new DirectExchange(ITEM_DIRECT_EXCHANGE);
    }

    /**
     * 声明队列名称
     *
     * @return
     */
    @Bean("itemQueue")
    public Queue itemQueue() {
        return new Queue(ITEM_QUEUE);
    }

    /**
     * 交换机和队列绑定
     *
     * @param directExchange
     * @param itemQueue
     * @return
     */
    @Bean
    public Binding bindingDirectExchange(@Qualifier("itemDirectExchange") DirectExchange directExchange,
                                         @Qualifier("itemQueue") Queue itemQueue) {
        return BindingBuilder.bind(itemQueue).to(directExchange).with(ITEM_QUEUE);
    }

}

2.4 编写RabbitMQController

package com.cn.fb.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Date;

/**
 * @className: RabbitMQController
 * @Description: RabbitMQController
 * @Author: liangyongyong
 * @Date: 2022/3/23 20:51
 * @Version: 1.0.0
 */
@RestController
public class RabbitMQController {

    private Logger logger = LoggerFactory.getLogger(RabbitMQController.class);

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @GetMapping("/send")
    public String sendMessage() {
        final String message = new Date().toString();
        rabbitTemplate.convertSendAndReceive("itemDirectExchange", "itemQueue", message);
        logger.info("消息已发送：" + message);
        return "ok";
    }

}

3、 创建消费者工程

工程名：springboot-rabbitmq-consumer

3.1 引入以下依赖

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

3.2 编写application.properties

# 应用名称
spring.application.name=springboot-rabbitmq-consumer
# 应用服务 WEB 访问端口
server.port=8081
# RabbitMQ配置
spring.rabbitmq.virtual-host=/
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

3.3 编写 AcceptService

package com.cn.fb.service;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Service;

/**
 * @className: acceptService
 * @Description: acceptService
 * @Author: liangyongyong
 * @Date: 2022/3/23 20:58
 * @Version: 1.0.0
 */
@Service
public class AcceptService {

    private Logger logger = LoggerFactory.getLogger(AcceptService.class);

    /**
     * 侦听itemQueue队列消息
     *
     * @param message
     */
    @RabbitListener(queues = "itemQueue")
    public void accept(String message) {
        logger.info("已接收到消息：" + message);
    }

}

4、 启动生产者（springboot-rabbitmq-producer）

5、 访问浏览器

地址：http://localhost:8080/send

6、 查看RabbitMQ Management

7、 启动消费者（springboot-rabbitmq-consumer）
