3. 实现

/**
 * 公司员工导入
 */
void companyStaffImport(@RequestParam("file") MultipartFile file) {
  
    ImportParams importParams = new ImportParams();
    // 因为Excel是从第3行开始才有正式数据,所以我们这里从第2行开始读取数据
    importParams.setHeadRows(2);
    // 这里是做非空验证,DTO中的数组必须不为空
    importParams.setImportFields(CompanyStaffExcelDTO.MUST_FILL);

    // 获取模板
    ExcelImportResult data;
    try {
        data = ExcelImportUtil.importExcelMore(file.getInputStream(), CompanyStaffExcelDTO.class, importParams);
    } catch (Exception e) {
        log.error(e.getMessage(), e);
        return Response.failure(BizError.EXCEL_ERROR);
    }

    // 获取模板数据
    List successList = data.getList();
    int total = successList.size();
    if (total == 0) {
   		// 如果数据量为0直接返回错误信息,不继续执行
        return Response.failure(BizError.EXCEL_NO_DATA);
    }
    
    // 循环数据
    for (CompanyStaffExcelDTO excelDTO : successList) {
    	// 取数据方式
    	excelDTO.getName()
        // 新增员工信息
        CompanyStaff companyStaff = new CompanyStaff();
        // 新增员工商保信息
        CompanyStaffInsurance companyStaffInsurance = new CompanyStaffInsurance();
        // 新增员工社保信息
        CompanyStaffSocial companyStaffSocial = new CompanyStaffSocial();
    }
    // 看情况返回信息
    return Response.success(vo);
