詳解Spring Boot 配置多個(gè)RabbitMQ
閑話
好久沒(méi)有寫(xiě)博客了,6月份畢業(yè),因?yàn)楣ぷ髟颍旧暇W(wǎng)受限,一直沒(méi)能把學(xué)到的知識(shí)點(diǎn)寫(xiě)下來(lái),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(lái)的東西少之又少,有時(shí)甚至能在同個(gè)問(wèn)題中踩了幾次,越來(lái)越覺(jué)得及時(shí)記錄一下學(xué)到的東西很重要。
好了,閑話少說(shuō),寫(xiě)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(gè)RabbitMQ的情況。。。
最近公司新啟動(dòng)一個(gè)新平臺(tái)的項(xiàng)目,需要用微服務(wù)這個(gè)這幾年很火的概念來(lái)做,所以就學(xué)習(xí)了Spring Boot方面的知識(shí),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(gè)RabbitMQ?下面就是在Spring Boot配置多個(gè)RabbitMQ的例子。是自己摸索搭建的,也不知道對(duì)不對(duì),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(cè)試
通過(guò)運(yùn)行HelloApplication.Java,將程序中的Receiver啟動(dòng)一直監(jiān)控著隊(duì)列,然后通過(guò)運(yùn)行TestDemo01.java中的測(cè)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(tái)將剛剛發(fā)送的消息打印出來(lái)
