1.在Linux环境上面装入rabbitMQ

doker-compose.yml

version: "3.1"
services:rabbitmq:image: daocloud.io/library/rabbitmq:managementrestart: alwayscontainer_name: rabbitmqports:- 6786:5672- 16786:15672volumes:- ./data:/var/lib/rabbitmq

doker-compose up -d 运行

2.进入rabbitMQ提供的客户端路径

自己的路径，和客户端端口号

RabbitMQ Management

http://8.140.244.227: 16786

3.在客户端注册虚拟主机

4.创建角色

5.给角色绑定虚拟主机

6.导入RabbitMQ依赖

        <dependency><groupId>com.rabbitmq</groupId><artifactId>amqp-client</artifactId><version>5.6.0</version></dependency>

7.写个工具类，获取连接

package com.qf.springbootRbMQ.utils;import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;public class MQUtils {public static Connection getConnection() throws Exception {//创建连接工厂对象ConnectionFactory connectionFactory = new ConnectionFactory();//设置MQ服务器的相关信息connectionFactory.setHost("8.140.244.227");connectionFactory.setPort(6786);//注意：不要写成管理工具的端口号connectionFactory.setUsername("root");connectionFactory.setPassword("1234");connectionFactory.setVirtualHost("/email");//设置虚拟主机Connection connection = connectionFactory.newConnection();return connection;}}

8.写提供者类Send

package com.qf.springbootRbMQ.email;import com.qf.springbootRbMQ.entity.EmailMessage;
import com.qf.springbootRbMQ.utils.MQUtils;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import org.springframework.util.SerializationUtils;public class Send {//队列的名字public static final String QUEUE_NAME="QQEmail";public static void main(String[] args) throws Exception {//1.获取连接对象Connection conn = MQUtils.getConnection();//2. 创建一个channel对象,对于MQ的大部分操作，都定义在了channel对象上Channel channel = conn.createChannel();//3.声明了一个队列/*** queue – the name of the queue* durable – true代表创建的队列是持久化的（当mq重启后，该对立依然存在）* exclusive – 该队列是不是排他的 (该对列是否只能由当前创建该队列的连接使用)* autoDelete – 该队列是否可以被mq服务器自动删除* arguments – 队列的其他参数，可以为null*/channel.queueDeclare(QUEUE_NAME, false, false, false, null);EmailMessage emailMessage = new EmailMessage();emailMessage.setQq("1393087444@QQ.com");emailMessage.setSubject("你好啊，又见面了，发送邮箱给你啊！！！");emailMessage.setText("<p style='color:green'>谢谢你看我的邮件啦啦啦~~~</p>");byte[] bytes = SerializationUtils.serialize(emailMessage);//生产者如何发送消息，使用下面的方法即可/*** exchange – 交换机的名字 ,如果是空串，说明是把消息发给了默认交换机* routingKey – 路由的key,当发送消息给默认交换机时，routingkey代表队列的名字* other properties - 消息的其他属性，可以为null* body – 消息的内容，注意，要是有 字节数组*/channel.basicPublish("", QUEUE_NAME, null, bytes);System.out.println(" [x] Sent '" + emailMessage + "'");//关闭资源channel.close();conn.close();}
}

9.写消费者类Recv

package com.qf.springbootRbMQ.email;import cn.hutool.core.collection.CollUtil;
import cn.hutool.extra.mail.MailAccount;
import cn.hutool.extra.mail.MailUtil;
import com.qf.springbootRbMQ.entity.EmailMessage;
import com.qf.springbootRbMQ.utils.MQUtils;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.DeliverCallback;
import com.rabbitmq.client.Delivery;
import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;
import org.springframework.util.SerializationUtils;import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
import java.io.IOException;public class Recv {private  final  static  String QUEUE_NAME="QQEmail";public static void custormer() throws Exception {//1.获取连接对象Connection conn = MQUtils.getConnection();//2. 创建一个channel对象,对于MQ的大部分操作，都定义在了channel对象上Channel channel = conn.createChannel();channel.queueDeclare(QUEUE_NAME, false, false, false, null);//3.该消费者收到消息之后的处理逻辑，写在DeliverCallback对象中DeliverCallback deliverCallback =new DeliverCallback() {@Overridepublic void handle(String consumerTag, Delivery message) throws IOException {//这个相当于标识，消费者的IDSystem.out.println(consumerTag);//从Delivery对象中可以获取到生产者，发送的消息的字节数组byte[] body = message.getBody();EmailMessage emailMessage = (EmailMessage) SerializationUtils.deserialize(body);System.out.println(emailMessage);//在这里写消费者的业务逻辑,例如,发送邮件MailAccount account = new MailAccount();account.setHost("smtp.qq.com"); // 设置SMTP服务器地址account.setPort(25); // 设置SMTP服务器端口account.setAuth(true); // 设置是否需要身份认证account.setFrom("1393087444@qq.com"); // 设置发件人邮箱地址account.setUser("1393087444@qq.com"); // 设置用户名account.setPass("gqrjqpilpadcjbdi"); // 设置密码// 发送邮件MailUtil.send(account, CollUtil.newArrayList("1393087444@qq.com"),emailMessage.getSubject(),emailMessage.getText(),false);}};//4.让当前消费者开始消费（QUEUE_NAME）队列中的消息/*** queue – the name of the queue* autoAck – true 代表当前消费者是不是自动确认模式。true代表自动确认。* deliverCallback – 当有消息发送给该消费者时，消费者如何处理消息的逻辑* cancelCallback – 当消费者被取消掉时，如果要执行代码，写到这里*/channel.basicConsume(QUEUE_NAME,true,deliverCallback,consumerTag -> {});}public static void main(String[] args) throws Exception {custormer();}
}
