好久没有写博客了，6月份毕业，因为工作原因，公司上网受限，一直没能把学到的知识点写下来，工作了半年，其实学到的东西也不少，但是现在回忆起来的东西少之又少，有时甚至能在同个问题中踩了几次，越来越觉得及时记录一下学到的东西很重要。
好了，闲话少说，写下这段时间学习的东西，先记录一下用spring Boot配置多个RabbitMQ的情况。。。
最近公司新启动一个新平台的项目，需要用微服务这个这几年很火的概念来做，所以就学习了Spring Boot方面的知识，给同事展示Spring Boot的一些小事例的时候，同事提出了可不可以配置多个RabbitMQ？下面就是在Spring Boot配置多个RabbitMQ的例子。是自己摸索搭建的，也不知道对不对，有其他好的实现方法的网友可以互相交流一下。
项目代码构造
关注点在红框的代码。。。
代码
下面就把项目的代码展示下来
