詳解Spring Boot 配置多個RabbitMQ
閑話
好久沒有寫博客了,6月份畢業(yè),因?yàn)楣ぷ髟颍旧暇W(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(shí)甚至能在同個問題中踩了幾次,越來越覺得及時(shí)記錄一下學(xué)到的東西很重要。
好了,閑話少說,寫下這段時(shí)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(shí)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。

運(yùn)行&測試
通過運(yùn)行HelloApplication.Java,將程序中的Receiver啟動一直監(jiān)控著隊(duì)列,然后通過運(yùn)行TestDemo01.java中的測試案例,發(fā)送消息到隊(duì)列中,這時(shí)可以發(fā)現(xiàn)運(yùn)行HelloApplication的程序控制臺將剛剛發(fā)送的消息打印出來
