分析原因
1.該異常是如何產生的
我是通過postman，發送一個post請求，導致該異常的。
從上面的異常信息來看，是因為該目錄[/tmp/tomcat.1428942566812653608.8090/work/Tomcat/localhost/ROOT]，不存在導致的。
2.該異常為何會產生
我的應用中沒有文件上傳，為啥會拋org.springframework.web.multipart.MultipartException異常
2.1）首先，我們應該知道，對於http POST請求來說，它需要使用這個臨時目錄來存儲post數據。
2.2）其次，因為該目錄是掛在到/temp目錄下的臨時文件，那么對於一些OS系統，像centOS將經常刪除這個臨時目錄，所有導致該目錄不存在了
解決方案
1.重啟你的項目就可以了（我采用的這種）
你還可以嘗試以下方式
2.在application.yml文件中設置multipart location ，並重啟項目
spring:
http:
multipart:
location: /data/upload_tmp
3.添加啟動參數 -java.tmp.dir=/path/to/application/temp/，並重啟
