技術版本選型：

比如你的SpringCloud是Hoxton.SR3版本，那么你的SpringBoot版本要在如下版本之間

Spring Boot >=2.2.0.M4 and <2.2.6.BUILD-SNAPSHOT

https://cloud.spring.io/spring-cloud-static/Hoxton.SR3/reference/html/spring-cloud.html

SpringCloud官網建議：

如果你使用是SpringCloud??Hoxton.SR3版本

那么Supported Boot Version:?2.2.5.RELEASE

即SpringBoot用?2.2.5.RELEASE 版本
