In Jsp tag should have this attribute

<form:form method="post" autocomplete="off"  enctype="multipart/form-data">

In controller

MultipartRequest multipartRequest = (MultipartRequest) request;

    String outputLocation = bwtPropertyHandler.getPropertyValue("outputDirectory");
    String OutputDir = outputLocation+"PrimaryKeyID";
    File f= new File(OutputDir);

    String attFilesize = String.valueOf(mfile.getSize());
        fileSizeTp = Double.valueOf(attFilesize).doubleValue();
     if(!(mfile.getSize() == 0))
     {
         f.mkdir();
    String outPutLocation = OutputDir +"/" + mfile.getOriginalFilename();
    java.io.OutputStream fso = new FileOutputStream(outPutLocation);
    FileCopyUtils.copy(is, fso);

     }
     else
     {
      system.out.print("File does not contain any data");
     }
