SpringCloud和SpringBoot對應的版本選型

SpringBoot版本選擇：

官網地址：https://spring.io/projects/spring-boot

 SpringBoot官方目前最新最穩定版：2.3.1，如果單獨使用SpringBoot的話，建議就可以選擇官方指定的最新最穩定版。

但是，如果需要和SpringCloud整合，就得看SpringCloud的版本需要適配SpringBoot的哪個版本了。

SpringCloud版本選擇：

官網地址：https://spring.io/projects/spring-cloud

SpringCloud采用了 英國倫敦地鐵站 的名稱來命名，並由地鐵站名稱首字母 A-Z 一次類推的形式來發布迭代版本。例如 Angel 是第一個版本，Brixton 是第二個版本...，目前最新版本是Hoxton。

另外，當SpringCloud的發布內容積累到臨界點或者一個重大BUG被解決后，會發布一個“service releases” 版本，簡稱 SRX 版本，比如當前的 Hoxton SR6，就是SpringCloud發布的Hoxton版本的第6個SRX版本。

一步到位選擇SpringBoot版本的辦法：https://spring.io/projects/spring-cloud#learn

 

 

 

不知道為啥，我從第一個頁面看到的是Hoxton SR6版本，點進去后成了SR5版本，估計是剛發布SR6版本，對應的還沒更新...

通過下面其他方式，也可以看到對應的版本信息，但是沒有上面這個詳細： 

 

在 https://spring.io/projects/spring-cloud#overview  中指定了不同的SpringCloud版本對應的SpringBoot版本：

 

官網建議：Hoxton版本的SpringCloud，需要對應2.2.x 版本的SpringBoot。
