[Springboot] spring-boot-starter-redis package error: unknown

When integrated springboot redis, incorporated springboot-starter-redis packet error, maven this resource can not be found in the following figure:

I project, spring boot is a version of 2.0.4. Springboot-Starter-Redis after springboot 1.4.7 version, instead of springboot-starter-data-redis,

So if you want integration redis, reference should be spring-boot-starter-data-redis.

If you just want to use the former, then it should be added to the version number.
