前言

Spring框架对RabbitMQ也提供了对应的Starter组件，我们只需要添加依赖和对应的配置即可直接集成RabbitMQ环境

整合

1、创建SpringBoot工程，添加RabbitMQ依赖

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

?2、编写工程配置

spring.application.name=springboot_rabbitmq
#我使用的是我电脑本地的RabbitMQ配置，所以是127.0.0.1
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.virtual-host=/
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.port=5672

3、编写RabbitMqConfig配置类

@Configuration
public class RabbitMqConfig {
    //初始化队列名称
    @Bean
    public Queue myQueue() {
        return new Queue("myqueue");
    }

    //声明交换器
    @Bean
    public Exchange myExchange() {
        return new DirectExchange("myExchange", false, false, null);
    }

    //绑定关系
    @Bean
    public Binding myBinding() {
        return new Binding("myqueue", Binding.DestinationType.QUEUE, "myExchange", "direct.biz.ex", null);
    }
}

4、编写接口

@RestController
public class TestController {
    @Autowired
    private AmqpTemplate amqpTemplate;

    @RequestMapping("/send/{msg}")
    public String sendMsg(@PathVariable("msg")String msg){
        amqpTemplate.convertAndSend("myExchange","direct.biz.ex",msg);
        return "OK";
    }
}

5、编写消费者监听类，用来获取并消费接口传过来的msg

@Component
public class TestConsumer {
    @RabbitListener(queues = "myqueue")
    public void consumerQueue(String msg) {
        System.out.println("消费的内容是：" + msg);
    }
}
