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：

Process finished with exit code 1

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。
