applyService的实现类：

  @Override
    public ResponseEntity doUploadExcel(MultipartFile file) {

        //文件保存路径
//        String targetFilePath = "F:\\javaCode\\jz-fzjlcx\\File\\excel\\";
        String targetFilePath = UPLOAD_PATH;
        //上传文件名
        String fileName = file.getOriginalFilename();

        //文件尾缀
        int lastNameKey = fileName.lastIndexOf(".");
        String[] fileNames = new String[]{fileName.substring(0,lastNameKey),fileName.substring(lastNameKey+1)};
        int endKey = fileNames.length - 1;
        String lastName = fileNames[endKey];
        //文件保存
        String newName = UUID.randomUUID().toString();
        File targetFile = new File(targetFilePath+ File.separator + newName + "." + lastName);
        FileOutputStream fileOutputStream = null;
        try {
            fileOutputStream = new FileOutputStream(targetFile);
             IOUtils.copy(file.getInputStream(),fileOutputStream);
        }catch (IOException e){
            e.printStackTrace();
            System.out.println("IO异常1");
            return new ResponseEntity(ResponseCode.FILE_IO_ERROR1);
        }finally {
            try {
                fileOutputStream.close();
            }catch (IOException e){
                System.out.println(e);
                return new ResponseEntity(ResponseCode.FILE_IO_ERROR2);
            }
        }
        //封装文件属性回执信息
        FilePro filePro = new FilePro();
        filePro.setSuffix(lastName);
        filePro.setFilePath(UPLOAD_PATH);
        filePro.setFileName(newName);
        filePro.setFileFullName(newName +"." + lastName);
        filePro.setFilePahtFullName(UPLOAD_PATH+newName +"." + lastName);
        ResponseEntity responseEntity = new ResponseEntity();
        responseEntity.addData(filePro);
        return responseEntity;
    }

        return this;
    }

    public ResponseEntity<T> success(T data) {
        return new ResponseEntity<T>(ResponseCode.SUCCESS).addData(data);
    }
    public ResponseEntity<T> success(Integer code,String message,T data) {
