若依 Excel导入与导出 配置下拉选项

    /**
     * 题目类型(字典配置)
     */
    @Excel(name = "题目类型(字典配置)", readConverterExp = "117=试卷类型1,118=试卷类型2,119=试卷类型3,120=试卷类型4", combo = "试卷类型1,试卷类型2,试卷类型3,试卷类型4")
    private String questionTypeId;

注意:下拉选项的字段必须是字符串类型

    /**
     * 成绩录入
     *
     * @param file
     * @return
     * @throws Exception
     */
    @ApiOperation("试题录入")
    @PostMapping("/common/scoreEntry")
    public AjaxResult scoreEntry(MultipartFile file) throws Exception {
        ExcelUtil<ExamQuestion> util = new ExcelUtil<>(ExamQuestion.class);
        List<ExamQuestion> userList = util.importExcel(file.getInputStream());

//        String message = bkRegistrationInfoService.importExcel(userList,updateSupport);
        return AjaxResult.success(JSONUtil.toJsonStr(userList));
    }


    /**

    @PreAuthorize("@ss.hasPermi('system:info:export')")
    @Log(title = "导出试题模版", businessType = BusinessType.EXPORT)
    @PostMapping("/export")
    public void export(HttpServletResponse response) {
        List<ExamQuestion> list = new ArrayList<>();
        ExcelUtil<ExamQuestion> util = new ExcelUtil<>(ExamQuestion.class);
        util.exportExcel(response, list, "报名信息数据");
