本篇文章主要介紹了spring-cloud入門(mén)之eureka-server（服務(wù)發(fā)現(xiàn)），小編覺(jué)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(guò)來(lái)看看吧

前言

Eureka是一個(gè)服務(wù)發(fā)現(xiàn)和注冊(cè)框架，細(xì)的來(lái)說(shuō)，我們可以分為eureka-server（服務(wù)發(fā)現(xiàn)）和eureka-client（服務(wù)注冊(cè)）兩個(gè)，本次我們對(duì)eureka-server（服務(wù)發(fā)現(xiàn)）做一個(gè)項(xiàng)目搭建，作為spring-cloud的開(kāi)篇。

項(xiàng)目結(jié)構(gòu)

maven結(jié)構(gòu)大家應(yīng)該都清楚（不清楚的需要補(bǔ)一補(bǔ)，百度關(guān)于maven的文章不計(jì)其數(shù)），下面我們來(lái)看一看這些關(guān)鍵文件的配置
