记一次文件上传报错解决过程The temporary upload location is not vali

写一个文件上传接口，报了如下错误：

Failed to parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location [C:Userss0661AppDataLocalTemp	omcat.7304072307918184638.9997workTomcatlocalhostROOT] is not vali

这个博客解释得很清楚 https://www.cnblogs.com/756623607-zhang/p/9721761.html

我做了tomcat配置有时还是会报入上错误，直接在C:Userss0661AppDataLocalTemp omcat.7304072307918184638.9997workTomcatlocalhost目录下创建一个ROOT文件夹即可[机智]。
