1、控制层

        因为前端设置了只能上传1个文件，这里直接取一个。

@RequestMapping(value = "/shebeiDaoru.ctrl", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")public @ResponseBody Map<String, Object> shebeiDaoru(HttpServletRequest request,@RequestParam("file") MultipartFile[] files) {return shebeiService.shebeiDaoru(files[0]);}

2、业务层（主要逻辑）

        通过multipartFile直接获取输入流，构建HSSFWorkbook。

@SuppressWarnings("resource")@Overridepublic Map<String, Object> shebeiDaoru(MultipartFile multipartFile) {try {Workbook workbook = new HSSFWorkbook(multipartFile.getInputStream());// 获取第一张sheet。Sheet sheetAt = workbook.getSheetAt(0);int index=0;for(Row row:sheetAt) {//跳过第一行if(index==0) {index++;continue;}Cell cell0 = row.getCell(0);Cell cell1 = row.getCell(1);Shebei shebei = new Shebei();shebei.setCode(cell0.getStringCellValue());shebei.setName(cell1.getStringCellValue());shebei.setStatus(JConstant.status_1);shebeiMapper.insert(shebei);}} catch (IOException e) {e.printStackTrace();}return null;}
