The final code is as follows:

     PublicResponseentity<inputstreamresource>downloadFile (Path filePath)throwsfilenotfoundexception {File file=Filepath.tofile (); String MimeType=Urlconnection.guesscontenttypefromname (File.getname ()); if(MimeType = =NULL) {MimeType=Mediatype.application_octet_stream_value; } httpheaders respheaders=Newhttpheaders ();        Respheaders.set (Httpheaders.content_type, MimeType);        Respheaders.setcontentlength (File.length ()); String Encodedfilename=File.getname (); Try{encodedfilename= Urlencoder.encode (Encodedfilename, "UTF-8"); } Catch(unsupportedencodingexception e) {logger.error ("File name encoding Error!" ", E); } Respheaders.set (httpheaders.content_disposition, "attachment; Filename=\ "" + encodedfilename + "\" "+"; Filename*=utf-8 "" + encodedfilename); Inputstreamresource ISR=NewInputstreamresource (Newfileinputstream (file)); return NewResponseentity<inputstreamresource>(ISR, Respheaders, Httpstatus.ok); }
