這篇文章主要介紹“怎么解決springBoot整合Eureka啟動失敗的問題”，在日常操作中，相信很多人在怎么解決springBoot整合Eureka啟動失敗的問題問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”怎么解決springBoot整合Eureka啟動失敗的問題”的疑惑有所幫助！接下來，請跟著小編一起來學習吧！
其實springBoot 整合Eureka 是比較簡單 ，可是我發現很多人整合后會啟動不了，我這里列出比較常見的報錯的原因
報：A child container failed during start
如圖下這樣
這個原因是因為pom.xml 沒有添加
<dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Finchley.SR1</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
假如添加后依然報錯：
報錯原因是因為Springboot 與 SpringCloud 版本不配對
修改后就行正常運行了！最后把他們相對應的版本貼出來，可以看著相對應的springboot版本改springCloud
Spring Boot Spring Cloud
1.2.x Angel版本
1.3.x Brixton版本
1.4.x stripes Camden版本
1.5.x Dalston版本、Edgware版本
2.0.x Finchley版本
Application run failed java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder
在測試Euruka作為服務注冊中心的時候碰到了這個問題，錯誤提示如下：

其根本原因是依賴包的版本沖突，我的這個pom.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.fangxing.springcloud</groupId> <artifactId>euruka-server</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>euruka-server</name> <description>Demo project for Eureka Server</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframewor k.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Camden.SR3</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
這里用到的SpringBoot版本為2.0.0.0版本，我們調整一下版本，改用下面的pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.fangxing.springcloud</groupId> <artifactId>euruka-server</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>euruka-server</name> <description>Demo project for Eureka Server</description> <!--基于Springboot--> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.0.RELEASE</version> <relativePath/> </parent> <properties> <!--設置字符編碼及java版本--> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.8</java.version> </properties> <dependencies> <!--增加eureka-server的依賴--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency> <!--用于測試的，本例可省略--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <!--依賴管理，用于管理spring-cloud的依賴，其中Camden.SR3是版本號--> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Camden.SR3</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
