Spring Cloud和Spring Boot版本

       今天在使用IDEA，基于Spring boot创建Spring cloud的maven项目时，创建成功后，无法正确启动，报错信息如下：

11:56:52.081 [main] ERROR org.springframework.boot.SpringApplication - Application run failed

       此时尝试修改Spring cloud和Spring boot的版本，Spring boot版本修改为2.2.1.RELEASE，Spring cloud版本修改为Hoxton.RELEAE。再次启动时，正常。说明出现该问题是由于Spring cloud和Spring boot版本不匹配导致，如下是Spring cloud和Spring boot的版本对应关系（来自官网）。

Release Train	Boot version
Hoxton	2.2.x
Greenwich	2.1.x
Finchley	2.0.x
Edgware	1.5.x
Dalston	1.5.x
