某项目需要，要进行相关图片的打包下载功能，已解决，踩坑后打卡，整理如下：
后端
获取需要打包的图片文件路径（图片链接或图片保存的本地路径），之后设置压缩包名称，各图片名称，输入输出流操作，等进行实现，代码如下：
Controller层:
@RequestMapping("/downloadImgs") public void downLoadImgs(Long id,HttpServletRequest request, HttpServletResponse response) { String basepath=getBasePath(); // 本地资源路径 basepath = Global.getProfile(); orderInfoService.downloadImgs(id,basepath,request,response); }Service层：（totalpassenger为信息列表，每条数据包含已获取的文件路径）
if(totalpassenger!=null&&totalpassenger.size()>0){ /*批量下载*/ try { String downloadFilename=""; String nowTimeString = String.valueOf(System.currentTimeMillis()); downloadFilename = order.getSysOrderNo()+"-"+order.getNickname()+".zip";//文件的名称 downloadFilename = URLEncoder.encode(downloadFilename, "UTF-8");//转换中文否则可能会产生乱码 response.setContentType("application/octet-stream");// 指明response的返回对象是文件流 response.setHeader("Content-Disposition", "attachment;filename=" + downloadFilename);// 设置在下载框默认显示的文件名 ZipOutputStream zos = new ZipOutputStream(response.getOutputStream()); FileInputStream ips = null; File file =new File(""); String url=""; byte[] buffer = new byte[1024]; int r=0; for (int i = 0; i < totalpassenger.size(); i++) { if(totalpassenger.get(i).getPassport_pic()!=null){ /* URL url2 = new URL(totalpassenger.get(i).getPassport_pic()); zos.putNextEntry(new ZipEntry(totalpassenger.get(i).getName()+"-护照"+".jpg")); InputStream fis2 = url2.openConnection().getInputStream(); while ((r = fis2.read(buffer)) != -1) { zos.write(buffer, 0, r); } fis2.close();*/ zos.putNextEntry(new ZipEntry(totalpassenger.get(i).getName()+"-护照"+".jpg")); url=totalpassenger.get(i).getPassport_pic(); //获取图片存放路径 file = new File(url); if(file.exists()) { ips = new FileInputStream(file); response.setContentType("multipart/form-data"); while ((r = ips.read(buffer)) != -1){ zos.write(buffer, 0, r); } if (null != ips) { ips.close(); } } } } zos.flush(); zos.close(); } catch (Exception e) { e.printStackTrace(); } }else{ return -1; }
