RabbitMQ 普通模式 (一)

1. 环境

• 部署rabbitMQ 使用docker在阿里云上部署，可通过访问ip+15672访问管理页面（使用默认端口情况下）

-- 搜索镜像
docker pull rabbitmq
-- 拉取镜像(指定版本)
docker pull rabbitmq:3.8.0-beta.4-management
-- 启动容器
docker run -d --hostname my-rabbit -p 5672:5672 -p 15672:15672 rabbitmq:3.8.0-beta.4-management

• maven依赖

        </dependency>

2. SimpleMQConfig 配置类

package com.yvxiao.rabbitmq_study.demo02.默认交换机;


import lombok.Getter;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * SimpleMQ配置类
 * @author zouxiaoao
 * @date 2022/3/23 16:00 
 */
@Configuration
@Getter
public class SimpleMQConfig {
    /**
     * 队列名
     */
    public static final String SIMPLE_QUEUE_NAME = "com.yvxiao.mq.simple";
    /**
     * 处理对象的MQ队列
     */
    public static final String HANDLER_OBJECT_QUEUE_NAME = "com.yvxiao.mq.simple.object";

    @Bean
    public Queue simpleQueue() {
        return new Queue(SIMPLE_QUEUE_NAME);
    }

    @Bean
    public Queue handleObjectQueue() {
        return new Queue(HANDLER_OBJECT_QUEUE_NAME);
    }

}

3. SimpleProducer Simple生产者

package com.yvxiao.rabbitmq_study.demo02.默认交换机;

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.yvxiao.rabbitmq_study.demo02.domain.Order;
import com.yvxiao.rabbitmq_study.demo02.domain.User;
import com.yvxiao.rabbitmq_study.demo02.user.api.domain.Teacher;

import lombok.extern.slf4j.Slf4j;

/**
 * 生产者
 * @author zouxiaoao
 * @date 2022/3/23 16:02
 */
@Slf4j
@Component
public class SimpleProducer {

    private RabbitTemplate rabbitTemplate;

    @Autowired
    public SimpleProducer(RabbitTemplate rabbitTemplate) {
        this.rabbitTemplate = rabbitTemplate;
    }

    /**
     * 发生消息到RabbitMQ,使用SpringBoot默认的交换机
     *
     * @param message
     */
    public void sendMessage(String message) {
        for (int i = 0; i < 20000; i++) {
            log.info("Simple 生产消息: ===> {}",i);
            rabbitTemplate.convertAndSend(SimpleMQConfig.SIMPLE_QUEUE_NAME, message+"===>"+i);
        }
    }

    public void sendTeacher(Teacher teacher){
        log.info("Teacher ===> {}",teacher);
        rabbitTemplate.convertAndSend(SimpleMQConfig.SIMPLE_QUEUE_NAME,teacher);
    }
}

4. SimpleConsumer 消费者

package com.yvxiao.rabbitmq_study.demo02.默认交换机;

import java.io.IOException;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.rabbitmq.client.Channel;
import com.yvxiao.rabbitmq_study.demo02.domain.Order;
import com.yvxiao.rabbitmq_study.demo02.user.api.domain.Teacher;
import com.yvxiao.rabbitmq_study.demo02.user.service.TeacherService;

import lombok.extern.slf4j.Slf4j;

/**
 * 消费者
 * @author zouxiaoao
 * @date 2022/3/23 16:28 
 */
@Component
@Slf4j
public class SimpleConsumer {


    @Autowired
    private TeacherService teacherService;

    @RabbitListener(queues = {SimpleMQConfig.SIMPLE_QUEUE_NAME})
    @RabbitHandler
    public void receiveMessage(String message) {
        log.info("simple consumer receive the message: ===> {}", message);
    }

    @RabbitHandler
    @RabbitListener(queues = {SimpleMQConfig.SIMPLE_QUEUE_NAME})
    public void receiveTeacher(Teacher teacher, Channel channel, Message message) throws IOException {
        log.info("teacher ===> {}",teacher);
        teacherService.insert(teacher);
    }
}

Controller

package com.yvxiao.rabbitmq_study.demo02.user.controller;

import com.github.javafaker.Faker;
import com.yvxiao.rabbitmq_study.demo02.user.api.domain.Teacher;
import com.yvxiao.rabbitmq_study.demo02.user.service.TeacherService;
import com.yvxiao.rabbitmq_study.demo02.默认交换机.SimpleProducer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * TeacherController
 *
 * @author zouxiaoao
 * @date 2022年03⽉23⽇ 15:15
 */
@RestController （省略Service，Mapper）
public class TeacherController {

    @Autowired
    private TeacherService teacherService;

    @Autowired
    private SimpleProducer simpleProducer;

    @GetMapping(value = "/sendTeacher")
    public void sendTeacher(){
        for (int i = 0; i < 2; i++) {
            Faker faker = new Faker();
            Teacher teacher = new Teacher();
            teacher.setId(i);
            teacher.setName(faker.name().name());
            simpleProducer.sendTeacher(teacher);
        }
    }
}
