SpringBoot整合RabbitMQ

1、Maven依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
</parent>
<dependencies>

    <!-- springboot-web组件 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- 添加springboot对amqp的支持 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-lang3</artifactId>
    </dependency>
    <!--fastjson -->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.49</version>
    </dependency>

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
</dependencies>

2、配置类

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

/**
 * @ClassName RabbitMQConfig
 * @Author 蚂蚁课堂余胜军 QQ644064779 www.mayikt.com
 * @Version V1.0
 **/
@Component
public class RabbitMQConfig {
    /**
     * 定义交换机
     */
    private String EXCHANGE_SPRINGBOOT_NAME = "/mayikt_ex";


    /**
     * 短信队列
     */
    private String FANOUT_SMS_QUEUE = "fanout_sms_queue";
    /**
     * 邮件队列
     */
    private String FANOUT_EMAIL_QUEUE = "fanout_email_queue";

    /**
     * 配置smsQueue
     *
     * @return
     */
    @Bean
    public Queue smsQueue() {
        return new Queue(FANOUT_SMS_QUEUE);
    }

    /**
     * 配置emailQueue
     *
     * @return
     */
    @Bean
    public Queue emailQueue() {
        return new Queue(FANOUT_EMAIL_QUEUE);
    }

    /**
     * 配置fanoutExchange
     *
     * @return
     */
    @Bean
    public FanoutExchange fanoutExchange() {
        return new FanoutExchange(EXCHANGE_SPRINGBOOT_NAME);
    }

    // 绑定交换机 sms
    @Bean
    public Binding bindingSmsFanoutExchange(Queue smsQueue, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(smsQueue).to(fanoutExchange);
    }

    // 绑定交换机 email
    @Bean
    public Binding bindingEmailFanoutExchange(Queue emailQueue, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(emailQueue).to(fanoutExchange);
    }
}

3、配置文件

spring:
  rabbitmq:
    ####连接地址
    host: 127.0.0.1
    ####端口号
    port: 5672
    ####账号
    username: guest
    ####密码
    password: guest
    ### 地址
    virtual-host: /meiteVirtualHosts

4、生产者

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class FanoutProducer {

    @Autowired
    private AmqpTemplate amqpTemplate;

    /**
     * 发送消息
     *
     * @return
     */
    @RequestMapping("/sendMsg")
    public String sendMsg(String msg) {
        /**
         * 1.交换机名称
         * 2.路由key名称
         * 3.发送内容
         */
        amqpTemplate.convertAndSend("/mayikt_ex", "", msg);
        return "success";
    }
}

5、消费者

import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;


@Slf4j
@Component
@RabbitListener(queues = "fanout_email_queue")
public class FanoutEmailConsumer {

    @RabbitHandler
    public void process(String msg) {
        log.info(">>邮件消费者消息msg:{}<<", msg);
    }
}

6、Entity

import lombok.Data;
import org.springframework.stereotype.Component;

import java.io.Serializable;


@Data
public class MsgEntity implements Serializable {
    private String msgId;
    private String userId;
    private String phone;
    private String email;

    public MsgEntity(String msgId, String userId, String phone, String email) {
        this.msgId = msgId;
        this.userId = userId;
        this.phone = phone;
        this.email = email;
    }
}
