记录fastDFS springboot整合的一次错误

错误：
Description:

Configuration property name 'fdfs.thumbImage' is not valid:

Invalid characters: 'I'
Bean: fastDFSClientWrapper
Reason: Canonical names should be kebab-case ('-' separated), lowercase alpha-numeric characters and must start with a letter

Action:

Modify 'fdfs.thumbImage' so that it conforms to the canonical names requirements.

springboot版本为2.0.1会报这个错误。换成1.5.2就好了
