这个错误原因是因为项目中Spring Boot和Spring Cloud的版本不兼容导致的。
先来看看官网对Spring Boot和Spring Cloud的版本对应关系，
https://spring.io/projects/spring-cloud

在下面有一句话这个版本下面有一句话

Spring Cloud Dalston, Edgware, Finchley, and Greenwich have all reached end of life status and are no longer supported.

翻译过来就是说

Spring Cloud Dalston，Edgware，Finchley和Greenwich的生命周期均已终止，不再受支持。

现在了解了版本之间的关联之后，就可以检查项目中的版本对应关系了，
以我这个为例

我Spring Cloud版本为Hoxton.SR10对应的就该是Spring Boot的2.2.x到2.3.x，但是我在创建项目的时候自动导入了Spring Boot 2.5的依赖

这就导致了版本不兼容报错。

只需要更改Spring Boot的版本为2.3.3.RELEASE
项目就能正常运行了。
