前言
近年SpringCloud與SpringBoot更新迭代非常頻繁，導致我們對兩者的版本選型非常的困難。若是版本選擇有問題, 會導致開發中調試兼容性占用非常多的得必要時間。
SpringCloud版本介紹
Spring Cloud是一個由眾多獨立子項目組成的大型綜合項目，每個子項目有不同的發行節奏，都維護着自己的發布版本號。Spring Cloud通過一個資源清單BOM（Bill of Materials）來管理每個版本的子項目清單。為避免與子項目的發布號混淆，所以沒有采用版本號的方式，而是通過命名的方式。
這些版本名稱的命名方式采用了倫敦地鐵站的名稱，同時根據字母表的順序來對應版本時間順序，比如：最早的Release版本：Angel，第二個Release版本：Brixton，然后是Camden、Dalston、Edgware、Finchley、Greenwich、Hoxton，目前最新穩定版本是Hoxton SR3版。

SpringBoot版本介紹
Spring發布的Dalston已於2018年12月31日宣布報廢, SpringBoot1.5x也即將不在維護, Spring官方強烈建議升級SpringBoot2.0。Spring Boot 2.0要求Java 8為最低版本，也已經在Java9上進行過測試。
