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。
