实际工作中，如果二者版本对应不上，会出现各种各样的兼容性的问题，Spring Cloud版本代号使用的是英文标识，是英国London的地铁站名，因为一个版本包含的组件模块太多了，版本不一，不能统一的用类似Spring Boot数字版本号来表示。

一、 官方文档查看

在官网的Spring Cloud版本Hoxton SR7的Reference Doc中的内容如下，指定支持的boot版本为2.3.2.RELEASE：

Release Train Version: Hoxton.SR7

Supported Boot Version: 2.3.2.RELEASE

根据此官方文档得知该cloud版本兼容的boot版本只有一个，boot无法进行小范围的版本的调整。

二、 更优的查看方式

springCloud官方提供最准确的springCloud,springBoot版本对应关系，可通过如下网址查看：

}

根据以下依据：
"Hoxton.SR7": "Spring Boot >=2.2.0.M4 and <2.3.4.BUILD-SNAPSHOT"

可知，springCloud的Hoxton.SR7版本对应spring Boot的版本范围是Spring Boot >=2.2.0.M4 and <2.3.4.BUILD-SNAPSHOT。

此网站返回内容，除了包含springCloud和springBoot的版本对应关系，还有其他组件和springBoot之间的版本对应关系，如下为mybatis和springBoot的兼容版本：

"mybatis": {

    "2.0.1": "Spring Boot >=2.0.0.RELEASE and <2.1.0.RELEASE",

    "2.1.3": "Spring Boot >=2.1.0.RELEASE and <2.4.0-M1"
