本文介绍了SpringBoot项目中遇到的文件上传异常，即由于/Linux系统的tmpwatch命令删除了Tomcat的临时文件目录导致的问题。解决方案包括重启SpringBoot应用或修改配置以指定新的临时文件目录。作者提醒开发者注意上线项目的预警机制和问题排查。

前言：

之前上线半个月后的项目，突然发现图片上传的接口有问题，无法上传，提示java.io.IOException: The temporary upload location [/tmp/tomcat.7538204303517105479.8899/work/Tomcat/localhost/main_service] is not valid的异常，经过百度，才知道这个是springboot项目文件上传的一个坑。

正文：

我们先复现下问题：

1.用postman调用图片上传的接口

2. 登录xshell去查看下日志
