学习Spring Cloud的时候，不是随便弄从maven仓库复制几个坐标就可以了，而是必须要知道Spring boot与Spring Cloud版本对应的关系，否则，项目有可能起不来。

解释例子：
"spring-cloud": {
"Hoxton.SR12": "Spring Boot >=2.2.0.RELEASE and <2.4.0.M1",
"2020.0.5": "Spring Boot >=2.4.0.M1 and <2.6.0-M1",
"2021.0.0-M1": "Spring Boot >=2.6.0-M1 and <2.6.0-M3",
"2021.0.0-M3": "Spring Boot >=2.6.0-M3 and <2.6.0-RC1",
"2021.0.0-RC1": "Spring Boot >=2.6.0-RC1 and <2.6.1",
"2021.0.2": "Spring Boot >=2.6.1 and <2.6.9-SNAPSHOT",
"2021.0.3-SNAPSHOT": "Spring Boot >=2.6.9-SNAPSHOT and <3.0.0-M1",
"2022.0.0-M1": "Spring Boot >=3.0.0-M1 and <3.0.0-M2",
"2022.0.0-M2": "Spring Boot >=3.0.0-M2 and <3.1.0-M1"
},
例如：“2021.0.2”: “Spring Boot >=2.6.1 and <2.6.9-SNAPSHOT”，表示如果Spring Cloud版本为2021.0.2，那么，Spring Boot 的版本就必须大于2.6.1并且小于2.6.9。
