java.nio.file.NoSuchFileException異常問(wèn)題及解決過(guò)程
更新時(shí)間：2025年08月30日 09:13:10 作者：清風(fēng)-云煙
SpringBoot數(shù)據(jù)導(dǎo)入接口異常因Linux臨時(shí)目錄被清理導(dǎo)致路徑缺失,需手動(dòng)配置上傳路徑為/home/tmp并確保目錄存在及權(quán)限,避免Files.createFile()找不到父目錄
項(xiàng)目場(chǎng)景
線上環(huán)境做做數(shù)據(jù)導(dǎo)入操作
問(wèn)題描述
項(xiàng)目中有一個(gè)數(shù)據(jù)導(dǎo)入的功能，在調(diào)用接口時(shí)，返回接口異常。
異常信息如下：

原因分析
在 Linux 系統(tǒng)中，Spring Boot 應(yīng)用以 java -jar 命令啟動(dòng)時(shí)，會(huì)在操作系統(tǒng)的 /tmp 目錄下生成一個(gè) tomcat（或 undertow ）臨時(shí)目錄，上傳的文件先要轉(zhuǎn)換成臨時(shí)文件保存在這個(gè)文件夾下面。
由于臨時(shí) /tmp 目錄下的文件，在長(zhǎng)時(shí)間（10天）沒(méi)有使用的情況下，系統(tǒng)執(zhí)行了 tmp 目錄清理服務(wù)（systemd-tmpfiles-clean.service）,導(dǎo)致 /tmp/undertow…8090 文件被清理，然而在上傳的時(shí)候，undertow 服務(wù)器需要?jiǎng)?chuàng)建/tmp/undertow…8090/undertow…upload 臨時(shí)文件，但是調(diào)用 Files.createFile(…) 的時(shí)候就會(huì)發(fā)現(xiàn)找不到父目錄，才導(dǎo)致了以上的錯(cuò)誤。
解決方案
在項(xiàng)目中 applicaiton.yml 中添加配置 ：
spring: servlet: multipart: location: /home/tmp
手動(dòng)指定目錄后，必須保證該目錄存在，并有讀寫的權(quán)限，創(chuàng)建該目錄 mkdir -p /home/tmp
總結(jié)
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
