                                FileInputStream excelFile = new FileInputStream(new File(FILE_NAME));
                                Workbook workbook = new XSSFWorkbook(excelFile);
                                Sheet datatypeSheet = workbook.getSheetAt(0);
                                Iterator<Row> iterator = datatypeSheet.iterator();
                            } catch (Exception adfasdasd) {
                                adfasdasd.printStackTrace();
                            }
                        } catch (FileUploadException ex) {
//                            Logger.getLogger(PropertyController.class.getName()).log(Level.SEVERE, null, ex);
                        } catch (IOException exp) {
//                            Logger.getLogger(PropertyController.class.getName()).log(Level.SEVERE, null, exp);
                        }

FileInputStream excelFile = new FileInputStream(new File(FILE_NAME((;为此，我需要上传文件的完整路径。我如何获得它？
