SpringBoot文件上传错误

错误如下，解决很简单 Description:

Failed to bind properties under 'spring.servlet.multipart.max-file-size' to org.springframework.util.unit.DataSize:

    Property: spring.servlet.multipart.max-file-size
    Value: 30Mb
    Origin: class path resource [application.properties]:22:40
    Reason: failed to convert java.lang.String to org.springframework.util.unit.DataSize

Action:

Update your application's configuration

我们只需要把Mb 改为MB即可，两个均是大些，KB亦如此
