java easyexcel读取多个sheet示例代码

以下是利用alibaba easyexcel读取excel中多个sheet中的参考示例代码：

controller控制层方法：

     @ApiOperation("上传文件")
     @RequestMapping(value = "/upload", method = RequestMethod.POST)
     public R upload(@RequestParam("file") MultipartFile file,@RequestParam(value = "processType",required = false) Integer processType,@RequestParam(value = "sourceAuditId",required = false) Integer auditId) throws Exception {

        // 获取文件名
        if(file==null){
            return  R.error("文件不能为空");
        }
        String fileName = file.getOriginalFilename();
        if (StringUtils.isEmpty(fileName)){
            return  R.error("文件名不能为空");
        }
        // 获取文件后缀
        String prefix=fileName.substring(fileName.lastIndexOf("."));
        if (!prefix.toLowerCase().contains("xls") && !prefix.toLowerCase().contains("xlsx") ){
            return  R.error("文件格式异常，请上传Excel文件格式");
        }
        //由于2003和2007的版本所使用的接口不一样，所以这里统一用Workbook做兼容
        boolean isExcel2003 = prefix.toLowerCase().endsWith("xls")?true:false;
        InputStream inputStream=null;
        UploadAssetDataVO uploadAssetDataVO=null;
        try{
            inputStream= file.getInputStream();
            uploadAssetDataVO = uploadAssetService.uploadAssetData(inputStream,processType,isExcel2003);
            return R.okWithData(uploadAssetDataVO);
        }catch (Exception e){
            e.printStackTrace();
            if(e.getMessage()!=null&&( e.getMessage().contains("Office")|| e.getMessage().contains("模板") ) ){
                return R.error("上传失败,原因如下："+"导入模板不对");
            }else{
                return R.error("上传失败,原因如下："+e.getMessage());
            }

        }finally {
            if(inputStream!=null){
                inputStream.close();
            }
        }

    }

service实现类业务方法：
