1.方法调用
public void importExcel(HttpServletRequest request, HttpServletResponse response) throws IOException {
ItemController xlsMain = new ItemController();
ItemEntity xls = null;
List<ItemEntity> list = xlsMain.readXls(request, response);
for (int i = 0; i < list.size(); i++) {
xls = (ItemEntity) list.get(i);
itemService.save(xls);
}
}
2.读取xls文件内容
