java excel 导入试题

js读取导入的名称到对应的位置显示

$(function() {$('#myFile').on('change', function() {var originName = $(this).val();var fileName = originName.substring(originName.lastIndexOf('\\')+1);fileName = '<span class="am-badge">' + fileName + '</span>';$('#file-list').html(fileName);});});function importExcel() {var myFile = $("#myFile").val();if (myFile.length <= 0) {dialogFun("批量导入试题", "请选择导入内容", 0);return false;}$("#importP").submit();}

html代码实现

<div class="am-u-sm-8 am-u-md-6"><div class="am-form-group am-form-file"><button class="am-btn am-btn-danger am-btn-sm" type="button"><i class="am-icon-cloud-upload"></i> 选择要上传的文件</button><input id="myFile" type="file" value="" accept=".xls" name="myFile"/></div><div id="file-list"></div>
</div>
<div class="am-hide-sm-only am-u-md-4"></div>

<form action="/admin/quest/importExcel" method="post" id="importP" enctype="multipart/form-data" class="am-form">
</form>

后台代码实现

/*** 批量导入试题* /admin/quest/importExcel* @param request* @param file* @return*/@RequestMapping("/quest/importExcel")public String importExcel(HttpServletRequest request, @RequestParam("myFile") MultipartFile file) {try {Long companyId = SingletonLoginUtils.getCurrentCompanyId(request);logger.info("myFile:" + file.getName());examQuestionService.updateImportQuestionExcel(file, companyId);request.setAttribute("msg", "操作成功");} catch (BaseException e) {logger.error("QuestionAction.importExcel", e);request.setAttribute("msg", e.getMessage());return msgError;} catch (RecordFormatException e) {logger.error("QuestionAction.importExcel", e);request.setAttribute("msg", "图片格式化失败，请勿导入图片");return msgError;}catch (Exception e) {logger.error("AdminQuestionAction.randomQuestion", e);request.setAttribute("msg", e.getMessage());return msgError;}return "/common/success";}
