玩法2 如何从MultipartFormData获取DataPart

如何从 MultipartFormData 获取 DataPart？我找不到任何 API 来实现这一点。

Http.MultipartFormData formData = body.asMultipartFormData();

// simple form field
// there is NO getData() or something available
DataPart imageIdPart = formData.getData("dataKey");

// uploaded file
FilePart imagePart = formData.getFile("imageKey");

我不习惯在 Play 2.0 中使用 Java，但是类似的东西可以工作吗？

@BodyParser.Of(BodyParser.MultipartFormData.class)
public static Result index() {
    Http.MultipartFormData multipartFormData = request().body().asMultipartFormData();

    //ask the multipart to be form url encoded... 
    //and get the data
    String[] data = multipartFormData.asFormUrlEncoded().get("dataKey");

    //which should not impact such call
    Http.MultipartFormData.FilePart image = multipartFormData.getFile("imageKey");

    return ok("Got image: " + image.getFilename());
}
