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

                                    org.springframework.cloud                spring-cloud-dependencies                Finchley.SR1                pom                import                        

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：

    4.0.0    com.fangxing.springcloud    euruka-server    0.0.1-SNAPSHOT    jar    euruka-server    Demo project for Eureka Server            org.springframework.boot        spring-boot-starter-parent        2.0.0.RELEASE                         UTF-8        UTF-8        1.8                            org.springframework.boot            spring-boot-starter-web                            org.springframewor k.boot            spring-boot-starter-test            test                            org.springframework.cloud            spring-cloud-starter-eureka-server                                                    org.springframework.cloud                spring-cloud-dependencies                Camden.SR3                pom                import                                                                org.springframework.boot                spring-boot-maven-plugin                        

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

    4.0.0    com.fangxing.springcloud    euruka-server    0.0.1-SNAPSHOT    jar    euruka-server    Demo project for Eureka Server                org.springframework.boot        spring-boot-starter-parent        1.4.0.RELEASE                                UTF-8        1.8                                    org.springframework.cloud            spring-cloud-starter-eureka-server                                    org.springframework.boot            spring-boot-starter-test            test                                                        org.springframework.cloud                spring-cloud-dependencies                Camden.SR3                pom                import                                                                org.springframework.boot                spring-boot-maven-plugin                        

启用正常。
