springboot 项目在启动项目时，报链接rabbitmq报错

通过 Caused by 可以定位 vhost 名称没找到

1. 处理方式一（推荐）
   在 application.properties 文件中添加 spring.rabbitmq.virtual-host=my_vhost
2. 处理方式二（推荐）
   在 rabbitmq 管理后天中添加 my_vhost 目录
3. 处理方式三
   在启动docker时指定vhost ： RABBITMQ_DEFAULT_VHOST=my_vhost

docker run -d --name rabbitmq3.8.2-management-alpine -p 5672:5672 -p 15672:15672 --hostname myRabbit -e RABBITMQ_DEFAULT_VHOST=my_vhost  -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=123456 27676558455e
