springboot中的照片上传工具类
public class UploadImgUtils { private static String savePath = ""; /** * 上传照片工具类 * * @param file 文件 * @param workNo 工单号 * @param property 配置的环境(dev,prod,test) * @return * @throws OperationException */ public static String uploadImg(MultipartFile file, String workNo, String property) throws OperationException { if (file == null) { throw new OperationException(ReturnCodeEnum.OPERATION_IMG_IS_NULL); } if (file.getSize() > 1024 * 1024 * 1) { throw new OperationException(ReturnCodeEnum.OPERATION_IMG_SIZE_LARGE); } //获取文件后缀 String suffix = file.getOriginalFilename().substring(file.getOriginalFilename().lastIndexOf(".") + 1); if (!"jpg,jpeg,gif,png".toUpperCase().contains(suffix.toUpperCase())) { throw new OperationException(ReturnCodeEnum.OPERATION_IMG_FORM_ERROR); } //对savePath进行过赋值 getProperties(property); File savePathFile = new File(savePath); if (!savePathFile.exists()) { //若不存在该目录,则创建目录 savePathFile.mkdir(); } //用工单号作为唯一的标识符 String filename = workNo + "." + suffix; try { //将文件保存指定目录 file.transferTo(new File(savePath + filename)); } catch (Exception e) { throw new OperationException(e, ReturnCodeEnum.OPERATION_SAVE_IMG_ERROR); } //返回文件名称 return savePath + filename; } /** * 读取配置文件中的信息. * * @return */ private static void getProperties(String name) { YamlPropertiesFactoryBean factoryBean = new YamlPropertiesFactoryBean(); factoryBean.setResources(new ClassPathResource("application-" + name + ".yml")); factoryBean.afterPropertiesSet(); Properties object = factoryBean.getObject(); savePath = (String) object.get("operation.savePath"); } }
