分析原因

1.该异常是如何产生的
我是通过postman，发送一个post请求，导致该异常的。
从上面的异常信息来看，是因为该目录[/tmp/tomcat.1428942566812653608.8090/work/Tomcat/localhost/ROOT]，不存在导致的。
2.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
2.1）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。
2.2）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

解决方案

1.重启你的项目就可以了（我采用的这种）
你还可以尝试以下方式
2.在application.yml文件中设置multipart location ，并重启项目

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

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