需求：根据excel模板导入数据
sheet1：1-6行为固定格式，且需要取值({xxx});7行开始为数据集合(list)
sheet2：都为固定格式，取值地方：{xxx}
1、数据格式（两个Sheet）
2、代码
public static EngineerTunnelMonitorExcelVo importExcel(MultipartFile file){ if(file.isEmpty()){ return null; } EngineerTunnelMonitorExcelVo result=new EngineerTunnelMonitorExcelVo(); //获取excel对象 Workbook workbook= null;
