既然已经搜到这了，估计RabbitMQ是干啥的就不用说了，这块调试的时候遇到了各种bug，解决了之后就又走了一遍记录一下，如下。
首先是配置问题，推荐RabbitMQ安装配置，我是在win下的，直接走这个程序就行，注意：有一个插件环节需要注意一下（得搞），一定要测试到localhost:15672能正确显示和登录！（username：guest；password：guest）。
下面这个异常是最开始在Spring+Tomcat运行的时候显示的，各种查之后发现是上面插件的环节没搞，然后也没测试win下rabbitMQ运行（rabbit-server.bat）的时候15672端口能不能正确访问和登录。

rabbitmq.host=localhost rabbitmq.port=5672 rabbitmq.username=wpi rabbitmq.password=wpiqueue20190601完成这两步，再restart，我的就不再报错了，欢迎讨论
