二、原因：
项目启动时会创建一个临时目录存放数据
三、解决方法1既然没有目录，创建一个类重新指定目录
@Configuration(proxyBeanMethods = false)
public class MultipartConfig {
@Bean
MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
// C:/Users/xxx/.ruoyi/file/tmp
String location = System.getProperty("user.home") + "/.ruoyi/file/tmp";
File tmpFile = new File(location);
if (!tmpFile.exists()) {
tmpFile.mkdirs();
}
factory.setLocation(location);
return factory.createMultipartConfig();
}
}
四、解决方法2
错误中提示路径被设置为：
is set to C:UsersADMINI~1AppDataLocalTemp2
直接创建以下目录就好了
注：目录中的 ADMINI~1 其实就是 Administrator 文件夹，我这里是少了提示路径中的 2 文件夹
其它解决方法：1. 重新指定临时文件位置 java -Djava.io.tempdir=D:/tmpdir -jar -my_project.jar
2. 手动创建指定文件夹
