springBoot整合Eureka启动失败如何解决(eureka,springboot,编程语言)

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：

<?xmlversion="1.0"encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://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>DemoprojectforEurekaServer</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.0.RELEASE</version><relativePath/><!--lookupparentfromrepository--></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.springframework.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

<?xmlversion="1.0"encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://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>DemoprojectforEurekaServer</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><!--设置字符编码及java版本--><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.8</java.version></properties><dependencies><!--增加eureka-server的依赖--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka-server</artifactId></dependency><!--用于测试的，本例可省略--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><!--依赖管理，用于管理spring-cloud的依赖，其中Camden.SR3是版本号--><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。
