我是靠谱客的博主自由向日葵，最近开发中收集的这篇文章主要介绍springboot 上传文件报错：java.io.IOException: The temporary upload location [/tmp/tomcat.xxx] is not valid，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

springboot 上传文件报错：java.io.IOException: The temporary upload location [/tmp/tomcat.xxx] is not valid

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.1920962677180834063.9092/work/Tomcat/localhost/ROOT] is not valid ，经过百度，才知道这个是springboot项目文件上传的一个坑。

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

解决方案一：

重启项目

解决方案二：

重启项目

1.在配置文件中配置tomcat的临时目录：

properties
server.tomcat.basedir=/home/temp
yml
server:
tomcat:
basedir: /home/temp

写个配置类，通过@Bean的方式配置目录：

/**
* 文件上传临时路径
*/
@Bean
MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setLocation("/home/temp");
return factory.createMultipartConfig();
}
