2、分析緣由

1.該異常是如何產生的

我是經過postman，發送一個post請求，致使該異常的。

從上面的異常信息來看，是由於該目錄[/tmp/tomcat.1428942566812653608.8090/work/Tomcat/localhost/ROOT]，不存在致使的。

 

2.該異常爲什麼會產生
個人應用中沒有文件上傳，爲啥會拋org.springframework.web.multipart.MultipartException異常
2.1）首先，咱們應該知道，對於http POST請求來講，它須要使用這個臨時目錄來存儲post數據。
2.2）其次，由於該目錄是掛在到/temp目錄下的臨時文件，那麼對於一些OS系統，像centOS將常常刪除這個臨時目錄，全部致使該目錄不存在了

 

3、解決方案

1.重啓你的項目就能夠了

你還能夠嘗試如下方式

2.在application.yml文件中設置multipart location ，並重啓項目

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

 

3.添加啓動參數 -java.tmp.dir=/path/to/application/temp/，並重啓
