在使用Spring Boot和RabbitMQ进行消息队列通信时，遇到创建队列miaosha.queue失败的问题，错误提示为找不到队列。解决办法是在@Configuration配置类中明确声明该队列。

解决思路

miaosha.queue队列找不到，排查发现没有在@Configuration文件中配置该队列，

在配置类中添加上相关队列即可

@Configuration
public class MQConfig {

    public static final String MIAOSHA_QUEUE = "miaosha.queue";

    @Bean
    public Queue miaoShaQueue(){
        return new Queue(MIAOSHA_QUEUE,true);
    }
}
