Spring Cloud Alibaba (一): SpringCloud与SpringBoot版本选型

前言

  近年SpringCloud与SpringBoot更新迭代非常频繁，导致我们对两者的版本选型非常的困难。若是版本选择有问题, 会导致开发中调试兼容性占用非常多的得必要时间。

SpringCloud版本介绍

  Spring Cloud是一个由众多独立子项目组成的大型综合项目，每个子项目有不同的发行节奏，都维护着自己的发布版本号。Spring Cloud通过一个资源清单BOM（Bill of Materials）来管理每个版本的子项目清单。为避免与子项目的发布号混淆，所以没有采用版本号的方式，而是通过命名的方式。

  这些版本名称的命名方式采用了伦敦地铁站的名称，同时根据字母表的顺序来对应版本时间顺序，比如：最早的Release版本：Angel，第二个Release版本：Brixton，然后是Camden、Dalston、Edgware、Finchley、Greenwich、Hoxton，目前最新稳定版本是Hoxton SR3版。

SpringBoot版本介绍

   Spring发布的Dalston已于2018年12月31日宣布报废, SpringBoot1.5x也即将不在维护, Spring官方强烈建议升级SpringBoot2.0。Spring Boot 2.0要求Java 8为最低版本，也已经在Java9上进行过测试。
