简介： 消息中间件系列教程（13） -RabbitMQ-SpringBoot集成RabbitMQ

本文来讲解SpringBoot集成RabbitMQ，代码已上传到Github，有兴趣的同学可以下载来看看：https://github.com/ylw-github/SpringBoot-RabbitMQ-Demo.git

1. 生产者

1.新建生产者maven项目RabbitMQ-Producer：

<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>
    </dependencies>

2.application.yml:

server:
  port: 8081
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: /

3.交换机绑定队列

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;
@Component
public class FanoutConfig {
    // 邮件队列
    private String FANOUT_EMAIL_QUEUE = "fanout_eamil_queue";
    // 短信队列
    private String FANOUT_SMS_QUEUE = "fanout_sms_queue";
    // 短信队列
    private String EXCHANGE_NAME = "fanoutExchange";
    // 1.定义队列邮件
    @Bean
    public Queue fanOutEamilQueue() {
        return new Queue(FANOUT_EMAIL_QUEUE);
    }
    @Bean
    public Queue fanOutSmsQueue() {
        return new Queue(FANOUT_SMS_QUEUE);
    }
    // 2.定义交换机
    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange(EXCHANGE_NAME);
    }
    // 3.队列与交换机绑定邮件队列
    @Bean
    Binding bindingExchangeEamil(Queue fanOutEamilQueue, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanOutEamilQueue).to(fanoutExchange);
    }
    // 4.队列与交换机绑定短信队列
    @Bean
    Binding bindingExchangeSms(Queue fanOutSmsQueue, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanOutSmsQueue).to(fanoutExchange);
    }
}

4.生产者

@Component
public class FanoutProducer {
    @Autowired
    private AmqpTemplate amqpTemplate;
    public void send(String queueName) {
        String msg = "my_fanout_msg:" + new Date();
        System.out.println(msg + ":" + msg);
        amqpTemplate.convertAndSend(queueName, msg);
    }
}

5.控制层调用代码

@RestController
public class ProducerController {
    @Autowired
    private FanoutProducer fanoutProducer;
    @RequestMapping("/sendFanout")
    public String sendFanout(String queueName) {
        fanoutProducer.send(queueName);
        return "success";
    }
}

2. 消费者

1.添加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>
    </dependencies>

2.application.yml

server:
  port: 8082
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: /

3.邮件消费者

@Component
@RabbitListener(queues = "fanout_eamil_queue")
public class FanoutEamilConsumer {
    @RabbitHandler
    public void process(String msg) throws Exception {
        System.out.println("邮件消费者获取生产者消息msg:" + msg);
    }
}

4.短信消费者

@Component
@RabbitListener(queues = "fanout_sms_queue")
public class FanoutSmsConsumer {
    @RabbitHandler
    public void process(String msg) {
        System.out.println("短信消费者获取生产者消息msg:" + msg);
    }
}
