Easy操作Excel导入

Controller

public GbmResult batchReadFile(@RequestParam(required = false,name ="file") MultipartFile file) throws IOException {
    String fileName = file.getOriginalFilename();
    String suffixName = fileName.substring(fileName.lastIndexOf("."));
    if (!(suffixName.equals(".xlsx"))) {
      System.out.println("请上传xlsx格式文件");
    }
    Listener listener = new Listener (TestService);    EasyExcel.read(file.getInputStream(),MgbsupplierBatchDto.class,listener).sheet().doRead();
    return Listener .getResult();
}
