SpringBoot+RabbitMQ简单实现Fanout模式

一、生产者

1.1maven依赖添加

    <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>

1.2 application.yml配置

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，最好在RabbitMQ自行添加virtual-host，建议不要用/
    virtual-host: /

1.3交换机绑定队列

@Component
public class FanoutConfig {

    /**
     * 邮件队列
     */
    private String FANOUT_EMAIL_QUEUE = "fanout_email_queue";

    /**
     * 短信队列
     * */
    private String FANOUT_SMS_QUEUE = "fanout_sms_queue";

    /**
     * 交换机
     * */
    private String EXCHANGE_NAME = "fanoutExchange";

    /**1.定义队列邮件
     *
     * @return
     */
    @Bean
    public Queue fanOutEmailQueue() {
        return new Queue(FANOUT_EMAIL_QUEUE);
    }

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

    /**2.定义交换机
     *
     * @return
     */
    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange(EXCHANGE_NAME);
    }

    /**
     * 3.队列与交换机绑定邮件队列
     * @param fanOutEmailQueue
     * @param fanoutExchange
     * @return
     */
    @Bean
    Binding bindingExchangeEmail(Queue fanOutEmailQueue, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanOutEmailQueue).to(fanoutExchange);
    }

    /**
     * 4.队列与交换机绑定短信队列
     * @param fanOutSmsQueue
     * @param fanoutExchange
     * @return
     */
    @Bean
    Binding bindingExchangeSms(Queue fanOutSmsQueue, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanOutSmsQueue).to(fanoutExchange);
    }

1.4 生产者投递消息

@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);
		//RabbitMQ将会忽略第二个参数,把消息分发给所有的队列(每个队列都有消息!)
		amqpTemplate.convertAndSend("fanoutExchange", queueName, msg);
	}
}

1.5 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";
	}
}

二、消费者

2.1 maven依赖添加

<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>

2.2 application.yml配置

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，最好在RabbitMQ自行添加virtual-host，建议不要用/
    virtual-host: /

2.3 消费

邮件消费者

@Component
@RabbitListener(queues = "fanout_email_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);
	}
}

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);
	}
}
