在项目开发中常遇到导出excel的处理，在开发中，发现如果是动态表头，原有poi处理起来麻烦不少，后来调研了下Hutool，发现处理起excel还是很方便的。话不多说，上代码。
一、excel导出

controller层

    @ApiOperation(value="教学任务-成绩录入-导出当前表格", notes="教学任务-成绩录入-导出当前表格方法", httpMethod="POST")
    @RequestMapping(value="/exportresultinputtable", method=RequestMethod.POST)
    public ResponseEntity<byte[]> exportResultInputTable(HttpServletRequest request, HttpServletResponse response) throws Exception {
        String currentUserId = "";
        Map<String, String> requestMap = RequestResponseUtils.getRequestBodyMap(request);// 获取请求页面的参数
        ResultInputExportExcel<TtTeachingTaskResultInputDto> exportExcel = iTtTeachingTaskResultInputService.exportResultInputTable(requestMap, currentUserId);//查询对应导出excel对象
        ExcelWriter writer = ExportExcelUtils.buildResultInputWorkBook(exportExcel);

        String fileName = "成绩录入-" + String.valueOf(System.currentTimeMillis()).substring(4, 13) + ".xls";
        // 下载显示的文件名，解决中文名称乱码问题
        String downloadFielName = URLEncoder.encode(fileName, "UTF-8");//new String(fileName.getBytes("UTF-8"),"iso-8859-1");
        // 下面开始设置HttpHeaders,使得浏览器响应下载
        HttpHeaders headers = new HttpHeaders();
        // 设置响应方式
        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
        // 设置响应文件
        headers.setContentDispositionFormData("attachment", downloadFielName);

        ByteArrayOutputStream outByteStream = null;
        try {
            outByteStream = new ByteArrayOutputStream();
            // 写出到文件
            writer.flush(outByteStream, true);
            // 关闭writer，释放内存
            writer.close();
        } catch (Exception e) {
            logger.error(e.getMessage());
            e.printStackTrace();
        }
        return new ResponseEntity<byte[]>(outByteStream.toByteArray(), headers, HttpStatus.CREATED);
    }

service层

public interface ITtTeachingTaskResultInputService {

    /**
     * 教学任务-成绩录入-导出当前表格
     * @param requestMap
     * @param currentUserId
     * @return
     */
    public ResultInputExportExcel<TtTeachingTaskResultInputDto> exportResultInputTable(Map<String, String> requestMap, String currentUserId);
    }

3.service实现层
