List stationList = staBiz.getRecordById("490");
String templateDir = "D:/excel/template/SupplyAreaMultipleEntityInSheet.xls";
String targetDir="D:/excel/export/testSupplyAreaMultipleEntityInSheet.xls";
InputStream is = new FileInputStream(templateDir);
OutputStream os = new FileOutputStream(targetDir);
Map beans = new HashMap();
beans.put("suplyArea", supplyAreaList);
beans.put("station", stationList);
XLSTransformer transFormer = new XLSTransformer();
HSSFWorkbook workBook = transFormer.transformXLS(is, beans);
workBook.write(os);
is.close();
os.flush();
