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

大家好，我是烤鸭:
下面又来踩坑实录了。主要是两个问题，第一是图片上传异常，第二是下载文件异常。其实都是在服务器上写入失败。有的人说是权限问题，但是这个一直没人动过。
由于过年放假，导致测试环境很长时间没动过。

The temporary upload location [/tmp/tomcat.xxx/work/Tomcat/localhost/etc] is not valid或者SXSSFSheet No such file or directory

2. 解决方案

这篇文章说的挺好的。
https://blog.csdn.net/eumenides_/article/details/84066539
springboot打jar包通过java -jar启动的项目，如果上传文件会在linux的/temp/下生成一个tomcat*的文件夹，上传的文件先要转换成临时文件保存在这个文件夹下面。由于临时/tmp目录下的文件，在长时间（10天）没有使用的情况下，就会被系统机制自动删除掉。所以如果系统长时间无人问津的话，就可能导致上面这个问题。

解决办法：

1. 临时的，直接重新启动项目就行，会重新建立临时文件夹
2. 在配置文件中配置tomcat的临时目录：

server.tomcat.basedir=/home/temp
