SpringAMQP+RabbitMQ调试中的问题解决

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。

上面解决了之后，restart ，你会发现报新的错误，就是下面这个，这个是说你的访问被拒绝了，简单来说就是你没有权限，

这个的解决方法还挺简单，我参考了一个Stack Overflow上的大神解决办法这是链接，首先你可以检查一下你的配置文件，域名，端口默认5672，用户明和密码，RabbitMQ服务器开启的情况下，你在前端看一下用户在不在你的用户列表里，因为最开始使用的话你只有guest一个用户，当然登录不上去，那么你添加了用户之后，还要给他相应的权限，那样就能正确访问了，下面有两个图。

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
