閑話
好久沒有寫博客了，6月份畢業，因為工作原因，公司上網受限，一直沒能把學到的知識點寫下來，工作了半年，其實學到的東西也不少，但是現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到的東西很重要。
好了，閑話少說，寫下這段時間學習的東西，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目，需要用微服務這個這幾年很火的概念來做，所以就學習了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，有其他好的實現方法的網友可以互相交流一下。

關注點在紅框的代碼。。。

運行&測試
通過運行HelloApplication.Java，將程序中的Receiver啟動一直監控著隊列，然后通過運行TestDemo01.java中的測試案例，發送消息到隊列中，這時可以發現運行HelloApplication的程序控制臺將剛剛發送的消息打印出來
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持服務器之家。
