推荐答案

您需要在new File(或new FileOutputStream)中指定绝对路径，具体取决于查找结果的方式文件).

You need to specify an absolute path in new File (or new FileOutputStream, depending on how you're locating the result file).

所以，不要

File file = new File("uploads/filename.ext");

但是愿意

File file = new File("/uploads/filename.ext");

(请注意开头的/)

通过这种方式，它将存储在磁盘文件系统中的确切位置上，而不是相对于启动JVM的目录.

This way it will be stored on exactly that location in the disk file system instead of relative to the directory from where the JVM is been started.
