批量下载图片并压缩为zip 格式

@GetMapping("/downLoadImgs")
    public void downLoadImgs(@RequestParam(value = "ids") String ids, HttpServletResponse response) throws Exception {
        //1.拿到对应图片地址的url数组
        String[] array = ids.split(",");
        //输出文件的名称
        String downloadFilename = System.currentTimeMillis() + ".zip";
        //转换中文否则可能会产生乱码
        downloadFilename = URLEncoder.encode(downloadFilename, "UTF-8");
        // 指明response的返回对象是文件流
        response.setContentType("application/octet-stream");
        // 设置在下载框默认显示的文件名
        response.setHeader("Content-Disposition", "attachment;filename=" + downloadFilename);
        ZipOutputStream zos = new ZipOutputStream(response.getOutputStream());
        int i = 0;
        ServletOutputStream out = null;
        FileInputStream ips = null;
        for (String s : array) {
            //获取图片存放路径
            String imgPath = filePath + File.separator + s;
            ips = new FileInputStream(new File(imgPath));
            String type = imgPath.substring(imgPath.indexOf(".") + 1);
　　　　　　　　//获取图片名称
            String name = imgPath.substring(imgPath.lastIndexOf("/") + 1);
            if ("png".equals(type)) {
                response.setContentType("image/png");
                zos.putNextEntry(new ZipEntry(name));
            }
            if ("jpeg".equals(type) || "jpg".equals(type)) {
                response.setContentType("image/jpeg");
                zos.putNextEntry(new ZipEntry(name));
            }
            byte[] buffer = new byte[1024];
            int r = 0;
            while ((r = ips.read(buffer)) != -1) {
                zos.write(buffer, 0, r);
            }
            ips.close();
        }
        zos.flush();
