3      controller层实现导出Excel表格

@RequestMapping("/importExc")
@ResponseBody
    public String importExc(HttpSession session){
        //标记是否验证成功
    boolean flag=false;
        //创建一个核心对象
    HSSFWorkbook hwb=new HSSFWorkbook();
    //新建一个Excel表格,括号内是表格名称
    HSSFSheet sheet = hwb.createSheet("第一张表");
    //设置每一列的宽度
   /* sheet.setColumnWidth("0",2000);*/

    //创建第一行
    HSSFRow hrow = sheet.createRow(0);
    //创建他的列
    HSSFCell [] hssfCells=new HSSFCell[8];

    //遍历列
    for (int i=0;i functionList = (List) session.getAttribute("functionList");
    for (int i=0; i
