第springBoot整合Eureka啟動(dòng)失敗的解決方案其實(shí)springBoot整合Eureka是比較簡(jiǎn)單，可是我發(fā)現(xiàn)很多人整合后會(huì)啟動(dòng)不了，我這里列出比較常見的報(bào)錯(cuò)的原因

報(bào)：Achildcontainerfailedduringstart

如圖下這樣

這個(gè)原因是因?yàn)閜om.xml沒有添加

dependencyManagement

dependencies

dependency

groupIdorg.springframework.cloud/groupId

artifactIdspring-cloud-dependencies/artifactId

versionFinchley.SR1/version

typepom/type

scopeimport/scope

/dependency

/dependencies

/dependencyManagement

假如添加后依然報(bào)錯(cuò)：

報(bào)錯(cuò)原因是因?yàn)镾pringboot與SpringCloud版本不配對(duì)

修改后就行正常運(yùn)行了！最后把他們相對(duì)應(yīng)的版本貼出來，可以看著相對(duì)應(yīng)的springboot版本改springCloud

SpringBootSpringCloud

1.2.xAngel版本

1.3.xBrixton版本

1.4.xstripesCamden版本

1.5.xDalston版本、Edgware版本

2.0.xFinchley版本

SpringCloud異常(Euruka)

Applicationrunfailedjava.lang.NoSuchMethodError:org.springframework.boot.builder.SpringApplicationBuilder

在測(cè)試Euruka作為服務(wù)注冊(cè)中心的時(shí)候碰到了這個(gè)問題，錯(cuò)誤提示如下：

其根本原因是依賴包的版本沖突，我的這個(gè)pom.xml文件如下：

這里用到的SpringBoot版本為版本，我們調(diào)整一下版本，改用下面的pom.xml
