excel练习题

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

<p class="am-u-sm-8 am-u-md-6">
    <p 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"/>
	</p>
    <p id="file-list"></p>
</p>
<p class="am-hide-sm-only am-u-md-4"></p>
<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";
	}

工具


public abstract class ConvertUtils {
    private static final decimalformat simpleFormat = new DecimalFormat("####");

    public static final boolean objectToBoolean(Object o) {
        return o != null?Boolean.valueOf(o.toString()).booleanValue():false;
    }

    public static final int objectToInt(Object o) {
        if(o instanceof Number) {
            return ((Number)o).intValue();
        } else {
            try {
                if(o == null) {
                    return -1;
                } else {
                    bigdecimal bigDecimal = new BigDecimal(o.toString());
                    bigDecimal.intValue();
                    return bigDecimal.intValue();
                }
            } catch (Exception var2) {
