前言
最近項(xiàng)目要使用RabbitMQ，網(wǎng)上已經(jīng)有很多優(yōu)秀的文章了，百度百科對(duì)RabbitMQ闡述也非常明確，建議去看下，還有amqp協(xié)議。必須一提的是rabbitmq是由LShift提供的一個(gè)消息隊(duì)列協(xié)議（AMQP)的開(kāi)源實(shí)現(xiàn)，由以高性能、健壯以及可伸縮性出名的Erlang寫(xiě)成（因此也是繼承了這些優(yōu)點(diǎn)）。
最近參考大神們的博客，自己做了一個(gè)RabbitMQ即時(shí)發(fā)消息的Demo。下面話不多說(shuō)了，來(lái)一起看看詳細(xì)的介紹吧。
步驟如下：
1.使用VS的NuGet安裝包管理工具安裝RabbitMQ.Client:

4.程序結(jié)果：
注：在第一步之前，你需要安裝RabbitMQ客戶端，可從http://www.rabbitmq.com/download.html下載，
但是RabbitMQ又是依賴于Erlang OTP平臺(tái)，所以，安裝RabbitMQ之前，需要先從http://www.erlang.org/download.html下載安裝erlang
總結(jié)
以上就是這篇文章的全部?jī)?nèi)容了，希望本文的內(nèi)容對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，如果有疑問(wèn)大家可以留言交流，謝謝大家對(duì)服務(wù)器之家的支持。
