Spring Boot如何 配置多個RabbitMQ

好久沒有寫博客了，6月份畢業(yè)，因?yàn)楣ぷ髟?，公司上網(wǎng)受限，一直沒能把學(xué)到的知識點(diǎn)寫下來，工作了半年，其實(shí)學(xué)到的東西也不少，但是現(xiàn)在回憶起來的東西少之又少，有時甚至能在同個問題中踩了幾次，越來越覺得及時記錄一下學(xué)到的東西很重要。

好了，閑話少說，寫下這段時間學(xué)習(xí)的東西，先記錄一下用spring Boot配置多個RabbitMQ的情況。。。

最近公司新啟動一個新平臺的項(xiàng)目，需要用微服務(wù)這個這幾年很火的概念來做，所以就學(xué)習(xí)了Spring Boot方面的知識，給同事展示Spring Boot的一些小事例的時候，同事提出了可不可以配置多個RabbitMQ？下面就是在Spring Boot配置多個RabbitMQ的例子。是自己摸索搭建的，也不知道對不對，有其他好的實(shí)現(xiàn)方法的網(wǎng)友可以互相交流一下。
