JavaFX学习之道：FileChooser 、POI导出Excel文件

以下是JavaFX中导出Excel的核心代码：

fileChooser.getExtensionFilters().add(new FileChooser.ExtensionFilter("XLS Files", "*.xls"));

File file = fileChooser.showSaveDialog(mRecordDetailStage);

if(file != null){

exportExcel(file.getAbsolutePath());

}

}

});

private void exportExcel(String fileName) {

// Declare a work sheet

workbook = new HSSFWorkbook();

// Generate a form

HSSFSheet sheet = workbook.createSheet("LaundryService记录");

// Set the table for 15 byte default column width

sheet.setDefaultColumnWidth((short) 15);

// Create a style

HSSFCellStyle style = workbook.createCellStyle();

// The style settings

style.setFillForegroundColor(HSSFColor.SKY_BLUE.index);

style.setBorderLeft(HSSFCellStyle.BORDER_THIN);

style.setBorderRight(HSSFCellStyle.BORDER_THIN);

// Create a font
