以下，是ZIP打包下载的关键编码：

友情说明：ZIP打包下载功能，行文中将其作为一个Service服务对外开放。测试验证的话，可自行创建Controller层，建议使用REST风格API，传入HttpServletResponse对象以及指定特定目录下的图片文件名称数据集（数据类型：List），即可完成测试！

public class CompressServiceImpl {
 private static final Logger logger = LoggerFactory.getLogger(CompressServiceImpl.class);
 /**
 * 下载ZIP格式压缩包
 *
 * @param imageNames 图片名称列表
 * @param response 响应体
 */
 public void downloadZipArchive(List<String> imageNames, HttpServletResponse response) {
 // 存放图片文件的目录所在路径,需自行调整（绝对路径或者相对路径皆可）
 String dirPath = "images/";
 try {
 OutputStream out = customizeResponse(response, String.valueOf(new Date().getTime()), "zip");
 ZipOutputStream zipOut = new ZipOutputStream(out);
 for (String imageName : imageNames) {
 // 文件夹路径
 String filePath = dirPath + imageName;
 byte[] data = Files.readAllBytes(new File(filePath).toPath());
 Path path = Paths.get(filePath);
 // 命名ZIP文件，打包时移除目录所在路径
 zipOut.putNextEntry(new ZipEntry(path.toFile().getName()));
 customizeOutputStream(zipOut, data, BUFFER_SIZE);
 zipOut.closeEntry();
 }
 zipOut.flush();
 zipOut.close();
 } catch (IOException e) {
 e.printStackTrace();
 logger.info("CompressServiceImpl.downloadZipArchive ========= 下载失败: [{}] =========", e.getMessage());
