Add in resources directory upload.

Or add this in constructor:

It's not a good solution for production applications, use it only for study purposes.

public UploadController() {
        if (!Files.exists(basePath)) {
            try {
                Files.createDirectories(basePath);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        var os = System.getProperty("os.name").toLowerCase();

        if (System.getProperty("os.name").toLowerCase().contains("windows")) {
            basePath = Paths.get(basePath.toString().replaceAll("/", "\\\\"));
        }
}
