我正在使用本教程在我的播放框架应用程序中上传文件。我正在使用完全相同的代码，但出现以下错误。

[IOException: Path(/Users/hrishikeshparanjape/Desktop) exists but replace parameter is false]

以下是我的代码：

def upload = Action(parse.multipartFormData) { request =>
        request.body.file("picture").map { picture =>
            import java.io.File
            val filename = picture.filename 
            val contentType = picture.contentType
            picture.ref.moveTo(new File("/Users/hrishikeshparanjape/Desktop/"))
            Ok("File uploaded")
        }.getOrElse {
            Redirect(routes.Application.index).flashing(
                    "error" -> "Missing file"
                    )
        }
    }

我被困在这里请帮忙。

看起来您需要指定完整的文件名moveTo

picture.ref.moveTo(new File(
  "/Users/hrishikeshparanjape/Desktop/" + picture.filename))
