詳解Spring Boot 配置多個(gè)RabbitMQ
更新時(shí)間：2017年06月23日 09:12:14 作者：1CSH1
本篇文章主要介紹了Spring Boot 配置多個(gè)RabbitMQ，小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧
閑話
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(shí)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(gè)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(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。
項(xiàng)目代碼構(gòu)造

運(yùn)行&測(cè)試
通過運(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
