读取照片信息并转对象

主要代码如下，依赖fastjson等通用的jar包。

/*** 分析照片并保存exif信息** @param photo* @return*/public void analysisDir(File photo) {try {Map<String, Object> exif = this.getImgExif(photo);ImageExif imgExifVo = JSONObject.parseObject(JSONObject.toJSONString(exif), ImageExif.class);imgExifVo.setFilePath(photo.getAbsolutePath());//todo 批量读取后，saveImageExif() 保存到表里} catch (Exception e) {e.printStackTrace();}}/*** 获取exif信息** @param jpegFile* @return* @throws ImageProcessingException* @throws IOException*/public Map<String, Object> getImgExif(File jpegFile) throws ImageProcessingException, IOException {Map<String, Object> exifMap = new HashMap<>();Metadata metadata = ImageMetadataReader.readMetadata(jpegFile);//获取图片所有EXIF信息Iterable<Directory> directories = metadata.getDirectories();for (Directory directory : directories) {for (Tag tag : directory.getTags()) {exifMap.put(tag.getTagName(), tag.getDescription());}}return exifMap;}/*** 保存图片exif信息** @param imgExifVoList*/private void saveImageExif(List<ImageExif> imgExifVoList) {for (ImageExif imgExifVo : imgExifVoList) {synchronized (this) {QueryWrapper<ImageExif> imageExifQueryWrapper = new QueryWrapper<>();imageExifQueryWrapper.eq("FILE_PATH", imgExifVo.getFilePath());ImageExif imageExif = imageExifService.getOne(imageExifQueryWrapper);if (imageExif == null) {imageExifService.save(imgExifVo);} else {imgExifVo.setId(imageExif.getId());imageExifService.updateById(imgExifVo);}}}}
