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

3.分析问题

spring boot的应用服务在启动的时候，会生成在操作系统的/tmp目录下生成一个tomcat.*的文件目录，用于"java.io.tmpdir"文件流操作。

程序对文件的操作时：会生成临时文件，暂存在临时文件中；lunix 系统的tmpwatch 命令会删除10天未使用的临时文件；长时间不操作，导致/tmp下面的tomcat临时文件目录被删除，且删除的文件不可恢复，上传文件时获取不到文件目录，所以就报了开头的错啦。

我进到/tmp的文件下，看有没有文件

4.解决方案1：重启下springboot项目，就可以解决，因为重启会重新生成这样的文件，我重启后，再看下/tmp下有没有文件

我们在访问下接口看下结果，发现就可以正常访问啦。

5.解决方案2：在springboot的配置文件里加个配置  

server.tomcat.basedir=/app/temp

这个路径需要你在Linux根目录下下建个/app/temp文件 

总结：

为什么会出现这个问题，具体原因我还没弄很清楚，稍后有新的进展，我会在更新上来。看来项目上线我们也不能轻易掉以轻心，预警机制要更加健全，及时发现问题和解决问题。
