ExtJS + Fileuploadfield upload file code

The backend server receives the code for the file:

/*** Background upload file handling action*/@RequestMapping (Value= "/uploadfile", method=requestmethod.post) PublicvoidUploadFile (@RequestParam (value= "file", required=true) multipartfile file , httpservletresponse response){modelmap Modelmap= NewModelmap (); String Savepath= "d:\\tmp\\";//SavePath

Try{String fileName = File.getname ();File SaveFile= NewFile (Savepath); if(!savefile.exists ())              {Savefile.mkdirs (); }  SaveFile =NewFile (Savepath, fileName); File.transferto (saveFile);Modelmap.addattribute ("Success",true);        } Catch(Exception e) {Modelmap.addattribute ("Success",false); Modelmap.addattribute ("message", "Save failed:" +e.getmessage ()); } Jsonserializer Serializer= NewJsonserializer (); String result=serializer.serialize (MODELMAP); //extjsupload requires this method to implement the returnResponse.setcontenttype ("Text/html;charset=utf-8"); PrintWriter writer=Response.getwriter ();        Writer.write (result);        Writer.flush ();    Writer.close (); }

Just started to return information using return Modelmap, but the foreground is not receiving data, finally look at the API after the use of PrintWriter to fix.

Attached to the front desk upload window code:

Uploadform =ext.extend (ext.window,{constructor:function (a) {Ext.applyif ( This, a);  This. inituicomponents (); UploadForm.superclass.constructor.call ( This, {layout:' Fit ', modal:true,//Mask layer constrain:true, Width:500, Height:200, Title:‘Select the Upload file window‘, Items: This.
