将图片链接转换成图片打成压缩包的工具类（有直接打包， 有分文件夹打包的）

public static void processImagesToZip(HttpServletResponse response, List<String> ossList) throws IOException {
		// 将 OSS 图片地址转换成图片文件
		List<File> fileList = new ArrayList<>();
		for (String ossUrl : ossList) {
			try {
				BufferedImage image = ImageIO.read(new URL(ossUrl));
				//

				String fileName = ossUrl.substring(ossUrl.lastIndexOf("/") + 1)+ UUID.randomUUID()+".jpg";
				File file = new File(fileName);
				ImageIO.write(image, "jpg", file);
				fileList.add(file);
			} catch (IOException e) {
				e.printStackTrace();
			}
		}

		// 打包压缩图片文件
		File zipFile = new File("kouqiang.zip");
		try (ZipOutputStream zipOut = new ZipOutputStream(new FileOutputStream(zipFile))) {
			byte[] buffer = new byte[1024];

			for (File file : fileList) {
				if (file.exists()) {
					ZipEntry zipEntry = new ZipEntry(file.getName());
					zipOut.putNextEntry(zipEntry);
