解决方法一：

1.重启服务。

2.增加启动参数–Djava.io.tmpdir=自定义目录

3.注入配置:

​​

@Bean MultipartConfigElement multipartConfigElement() { MultipartConfigFactory factory = new MultipartConfigFactory(); factory.setLocation("/app/pttms/tmp"); return factory.createMultipartConfig(); }

​​​​​解决方法二：

关闭linux服务器临时文件自动清理，例如：

centos下vi /usr/lib/tmpfiles.d/tmp.conf

增加

​​

x /var/tmp/tomcat.*
