原因分析：

在 Linux 系统中，Spring Boot 应用以 java –jar 命令启动时，会在操作系统的 /tmp 目录下生成一个 tomcat（或 undertow ）临时目录，上传的文件先要转换成临时文件保存在这个文件夹下面。由于临时 /tmp 目录下的文件，在长时间（10天）没有使用的情况下，系统执行了 tmp 目录清理服务（systemd–tmpfiles–clean.service）,导致 /tmp/undertow…8090 文件被清理，然而在上传的时候，undertow 服务器需要创建/tmp/undertow…8090/undertow…upload 临时文件，但是调用 Files.createFile(…) 的时候就会发现找不到父目录，才导致了以上的错误。

解决方案：

在项目中 applicaiton.yml 中添加配置 ：
spring:
servlet:
multipart:
location: /home/tmp
手动指定目录后，必须保证该目录存在，并有读写的权限，创建该目录 mkdir -p /home/tmp
