参考上面的数据，就知道版本对应关系了
SpringCloud的版本命名规则

SpringCloud现在（当前时间是2022年12月2日）使用日期来作为版本号。因为地铁站名用完了。

SpringCloud以前使用英国路段地铁站的名称来命名版本，并已地铁站名称字符A-Z依次类推的形式发布迭代版本。SpringCloud是一个由许多子项目组成的综合项目，各子项目有不同的发布节奏。为了管理SpringCloud与各子项目版本依赖关系，发布了一个清单，其中包括了某个SpringCloud版本对应的子项目版本。为了避免SpringCloud与各子项目版本号混淆，SpringCloud采用了字符名称而非数字版本号的命名.。例如 Angel是第一个版本，Brixton是第二个版本。当SpringCloud的发布内容积累到临界点或一个重大BUG被解决后，会发布一个service releases版本，简称SRX版本，比如Greenwich.SR2就是SpringCloud发布的Greenwich版本的第2个SRX版本。
