将表格放入 

前端用什么框架什么框架都可以Controller主要接收两个参数response和前端传过来的参数params

Controller: 

  @GetMapping("export")
    @ApiOperation("导出")
    @LogOperation("导出")
    @RequiresPermissions("fysjtsygt:fysjtsygt:export")
    public void export(@ApiIgnore @RequestParam Map<String, Object> params, HttpServletResponse response) throws Exception {

        String fileNmae = "土地台账";
        String date = DateUtils.format(new Date());
        String year = params.get("ydYear").toString();
        String orgName = params.get("orgName").toString();
        TemplateExportParams param = new TemplateExportParams("/excelTemplates/土地台账.xlsx", true);
        // 标题开始行
        // param.setHeadingStartRow(0);
        // 标题行数
        // param.setHeadingRows(2);
        // 设置sheetName，若不设置该参数，则使用得原本得sheet名称
        //param.setSheetName("班级信息");
