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

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:
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.
