SpringBoot整合RabbitMQ

1.生产者

1.创建生产者SpringBoot工程

2. 引入start，依赖坐标

	<dependency>
            		<groupId>org.springframework.boot</groupId>
            		<artifactId>spring-boot-starter-amqp</artifactId>
     	</dependency>

3. 编写yml配置，基本信息配置
4. 定义交换机，队列以及绑定关系的配置类
5. 注入RabbitTemplate，调用方法，完成消息发送

RabbitMQConfig

@Configuration
public class RabbitMQConfig {

    public static final String EXCHANGE_NAME = "boot_topic_exchange";
    public static final String QUEUE_NAME = "boot_queue";

    //1.交换机
    @Bean("bootExchange")
    public Exchange bootExchange(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }


    //2.Queue 队列
    @Bean("bootQueue")
    public Queue bootQueue(){
        return QueueBuilder.durable(QUEUE_NAME).build();
    }

    //3. 队列和交互机绑定关系 Binding
    /*
        1. 知道哪个队列
        2. 知道哪个交换机
        3. routing key
     */
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue, @Qualifier("bootExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }


}

ProducerApplication

@SpringBootApplication
public class ProducerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProducerApplication.class);
    }
}

application.yml

spring:
  rabbitmq:
    host: localhost #主机ip
    port: 5672 #端口
    username: guest
    password: guest
    virtual-host: /

2.消费者

1. 创建消费者SpringBoot工程
2. 引入start，依赖坐标

<dependency>
            		<groupId>org.springframework.boot</groupId>
            		<artifactId>spring-boot-starter-amqp</artifactId>
     	</dependency>

3. 编写yml配置，基本信息配置
4. 定义监听类，使用@RabbitListener注解完成队列监听。
   
   ConsumerSpringbootApplication

@SpringBootApplication
public class ConsumerSpringbootApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConsumerSpringbootApplication.class, args);
    }

}

RabbimtMQListener

@Component
public class RabbimtMQListener {

    @RabbitListener(queues = "boot_queue")
    public void ListenerQueue(Message message){
        //System.out.println(message);
        System.out.println(new String(message.getBody()));
    }

}

application.yml

spring:
  rabbitmq:
    host: localhost #主机ip
    port: 5672 #端口
    username: guest
    password: guest
    virtual-host: /

3.小结

• SpringBoot提供了快速整合RabbitMQ的方式
• 基本信息再yml中配置，队列交互机以及绑定关系在配置类中使用Bean的方式配置
• 生产端直接注入RabbitTemplate完成消息发送
• 消费端直接使用@RabbitListener完成消息接收
