JavaFX 选择文件 导入Excel文件并解析

FXML 控制器 :

@FXML
    public void selectExcel(MouseEvent event) {
        FileChooser fileChooser = new FileChooser();
        fileChooser.setTitle("选择Excel文件");
        Stage selectFile = new Stage();
        fileChooser.setInitialDirectory(new File(System.getProperty("user.home")));
        fileChooser.getExtensionFilters().addAll(new FileChooser.ExtensionFilter("All Excel", "*.xlsx"),
                new FileChooser.ExtensionFilter("XLS", "*.xls"), new FileChooser.ExtensionFilter("XLSX", "*.xlsx"));
        File file = fileChooser.showOpenDialog(selectFile);
        if (file != null) {
            try {
                bom.initBOM(ExcelUtil.importExcel(Util.getWorkbok(new FileInputStream(file), file)));
                session.commit();
                session.close();
                
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

    }
