1. 问题背景

    服务运行好好的,今天访问接口突然出现问题,报错如下:

nested exception is java.io.IOException: The temporary upload location [/tmp/tomcat.3961673492109766761.2005/work/Tomcat/localhost/ROOT] is not valid] with root cause

2. 原因分析

   A: 查看异常信息，是因为目录[/tmp/tomcat.3961673492109766761.2005/work/Tomcat/localhost/ROOT]，不存在导致的。

   B: 该异常为何会产生

       我的应用中没有文件上传，为啥会抛org.springframework.web.multipart.MultipartException异常

       首先，我们应该知道，对于http POST请求来说，它需要使用这个临时目录来存储post数据。

        其次，因为该目录是挂在到/temp目录下的临时文件，那么对于一些OS系统，像centOS将经常删除这个临时目录，所有导致该目录不存在了

3. 解决方案 

   方案1.重启你的项目就可以了

   方案2. 在application.yml文件中设置multipart location ，并重启项目   

spring:
   http:
     multipart:
        location: /data/upload_tmp

   方案3. 添加启动参数 -java.tmp.dir=/path/to/application/temp/，并重启
