            ExcelWriter writer = new ExcelWriter(out, ExcelTypeEnum.XLSX);
            Sheet sheet1 = new Sheet(1, 0, HrUserVo.class);
            sheet1.setSheetName("test");
            List<HrUserVo> data = new ArrayList<>();
            for (int i = 0; i < addUser.size(); i++) {
                HrUserVo item = new HrUserVo();
                HrUser hrUser = addUser.get(i);
                item.setE_name(hrUser.getE_name());
                data.add(item);
            }


            writer.write(data, sheet1);
            writer.finish();
        } catch (FileNotFoundException e) {

            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
