Springboot 以jar的方式启动报错：The temporary upload location [/tmp/tomcat.5249323735026096568.8022/work/Tomc

The temporary upload location [/tmp/tomcat.5249323735026096568.8022/work/Tomcat/localhost/ROOT] is not valid

解决方案：

在yml中配置

server:
  tomcat:
    basedir: /home/grandsun/upload_tmp

注意：之前使用了下面配置，结果没有任何效果

  servlet:
    multipart:
      max-file-size: 100MB
      max-request-size: 100MB
      location: /home/grandsun/upload_tmp

其它方式可以参考：
