缘起
初学spring cloud的朋友可能不知道，其实SpringBoot与SpringCloud需要版本对应，否则可能会造成很多意料之外的错误，比如eureka注册了结果找不到服务类啊，比如某些jar导入不进来啊，等等这些错误。下面列出来springBoot和spring cloud的版本对应关系，需要配套使用，才不会出现各种奇怪的错误。

关于maven仓库的版本列表
spring-cloud-dependencies 版本列表可查看：
https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-dependencies
spring-boot-starter-parent 版本列表可查看：
https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent

版本对应关系
大版本对应：

关于spring cloud1.x版本和2.x版本区别
spring cloud各个版本之间是有所区别的，比如在SpringCloud中，1.X和2.X版本在pom.xml中引入的jar包名字都不一样，比如有的叫spirng-cloud-starter-hystrix 有的叫spring-cloud-netflix-hystrix，维护起来会比较困难。

1.x版本pom.xml里几个基本用到的jar长这样：

	</project>

而在2.x版本中，比如我们需要eureka,去maven仓库中可能会看到deprecated, please use spring-cloud-starter-netflix-eureka-client这类提示，包括使用ribbon也会有

所以个人猜测2.x中统一用
spring-cloud-starter-netflix-xx 替换了原有的 spring-cloud-starter-xx(此处如有不正确请指出)
所以2.x的版本pom.xml类似如下这样

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
