EasyExcel动态实现表头以及数据封装
实现方法
public void exportSelfRanking(HttpServletResponse response, ButtonStatisticsParam buttonStatisticsParam) throws IOException {//表头参数List<List<String>> titleList = queryButtonExportTitle();//数据List<List<String>> dataList = queryButtonExportData(buttonStatisticsParam, titleList);//导出response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");response.setCharacterEncoding("utf-8");// 这里URLEncoder.encode可以防止中文乱码String fileName = URLEncoder.encode("使用情况数据"+DateUtil.format(new Date(),"yyyyMMddHHmmssSSS"), "UTF-8").replaceAll("\\+", "%20");response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + fileName + ".xlsx");EasyExcel.write(response.getOutputStream()).head(titleList).registerWriteHandler(new SimpleColumnWidthStyleStrategy(25)).sheet("功能意向使用情况").doWrite(dataList);}
注：buttonStatisticsParam为导出的检索条件，response为请求头参数
List<List> titleList 为封装的动态表头参数， List<List> dataList 为动态封装的数据参数，registerWriteHandler(new SimpleColumnWidthStyleStrategy(25)) 为设置表格参数，head(titleList) 为存放表头参数
