springBoot整合Eureka启动失败的解决方案

其实springBoot 整合Eureka 是比较简单，可是我发现很多人整合后会启动不了，我这里列出比较常见的报错的原因

报：A child container failed during start

如图下这样

这个原因是因为pom.xml 没有添加

<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>

假如添加后依然报错：

报错原因是因为Springboot 与 SpringCloud 版本不配对

修改后就行正常运行了！最后把他们相对应的版本贴出来，可以看着相对应的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

SpringCloud异常(Euruka)

Application run failed java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder

在测试Euruka作为服务注册中心的时候碰到了这个问题，错误提示如下：

其根本原因是依赖包的版本冲突，我的这个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://HdhCmsTestw3.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/>  </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>

这里用到的SpringBoot版本为2.0.0.0版本，我们调整一下版本，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://HdhCmsTestw3.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> 1.4.0.RELEASE </version> <relativePath/> </parent> <properties>  <project.build.sourceEncoding> UTF-8 </project.build.sourceEncoding> <java.version> 1.8 </java.version> </properties> <dependencies>  <dependency> <groupId> org.springframework.cloud </groupId> <artifactId> spring-cloud-starter-eureka-server </artifactId> </dependency>  <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter-test </artifactId> <scope> test </scope> </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>

启用正常。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持我们。
