如何在play 2.0.1中更改上传的文件目录？ [英] How can I change uploaded files directory in play 2.0.1?

问题描述

我试图在我的application.conf文件中指定attachments.path属性，但这没有任何效果。

I tried to specify attachments.path property in my application.conf file, but this had no effects.

在play 2.0.1的文档中，我没有'找到解释如何更改上传文件目录的任何内容。

In the documentation of play 2.0.1 I didn't find anything explaining how to change uploaded files directory.

我错过了什么？

推荐答案

虽然 application.conf 中没有这样的变量，但您可以轻松添加它并在您的方法中使用。按照您的意愿调用ie：

Although there is no such variable in application.conf you can easily add it and use in your method. Call it as you wish ie:

application.conf中的新行：

myUploadPath = "/home/your-account/some/custom/upload/folder/"

根据文档示例：

public static Result upload() {
    MultipartFormData body = request().body().asMultipartFormData();
    MultipartFormData.FilePart picture = body.getFile("picture");
    if (picture != null) {
        String fileName = picture.getFilename();
        String contentType = picture.getContentType();
        File file = picture.getFile();

        // added lines
        String myUploadPath = Play.application().configuration().getString("myUploadPath");
        file.renameTo(new File(myUploadPath, fileName));

        return ok("file saved as " + myUploadPath + fileName);
    } else {
        flash("error", "Missing file");
        return redirect(routes.Application.uploadform());
    }
}

使用这种方法你甚至可以执行 filename clash 重命名前检查，以防止随机覆盖。

Using this approach you can or even should perform filename clash check before renaming, to prevent random overwriting.
