java通过poi编写excel文件

public String writeExcel(List<MedicalWhiteList> MedicalWhiteList)
    {
        if(MedicalWhiteList == null || MedicalWhiteList.size() <= 0){
            log.info("****不存在失败记录***");
            return "";
        }
        //创建HSSFWorkbook对象
        HSSFWorkbook wb = new HSSFWorkbook();
        //创建HSSFSheet对象
        HSSFSheet sheet = wb.createSheet("sheet0");
        //创建HSSFRow对象
        HSSFRow row = sheet.createRow(0);
        //创建HSSFCell对象
        HSSFCell cell=row.createCell(0);
        //设置单元格的值
        cell.setCellValue("投保人手机号");
        //输出Excel文件
        
        row.createCell(1).setCellValue("投保人姓名");
        row.createCell(2).setCellValue("投保人证件类型");
        row.createCell(3).setCellValue("投保人证件号");for(int i = 0;i < MedicalWhiteList.size(); i++){
            
            HSSFRow rowf = sheet.createRow(i+1);
            MedicalWhiteList m = MedicalWhiteList.get(i);
            
            rowf.createCell(0).setCellValue(m.getHolderMobile());
            rowf.createCell(1).setCellValue(m.getHolderRealName());
            rowf.createCell(2).setCellValue(m.getHolderCertiType());
            rowf.createCell(3).setCellValue(m.getHolderCertiCode());
        }        
        
        //路径
        Date now =new Date();//获取时间 
        String filePath = DateUtils.dateToString(now, "yyyyMMdd")+"/";
        String absPath = Env.getProperty("MEDICALDATE_FILE_PATH")+filePath;// 保存路径
        
        String time = DateUtils.dateToString(now, "yyyyMMddHHmmss");
        String suffix = ".xls";
        
        String csvName = time+suffix;//文件名称
        String csvPath = absPath+csvName;//文件名称
        //路径
        
        File f = new File(absPath);
        if (!f.exists()) {
            f.mkdirs();
        }
        
        FileOutputStream output = null;
        try
        {
            //明天换路径
            output = new FileOutputStream(csvPath);
        } catch (FileNotFoundException e)
        {
            e.printStackTrace();
        }
        try
        {
            wb.write(output);
            output.flush();
        } catch (IOException e)
        {
            e.printStackTrace();
        }
        
        return csvPath;
    }
