java 多文件zip压缩包下载导出

---

1.根据自身需求修改

代码如下（示例）：

    @GetMapping("/downloadZip")
    public void downloadJyzByIdZip(String certificateTemplateId, HttpServletResponse response) {

        List<FileVo> voList = new ArrayList<>();
 		//文件
        System.out.println(voList);

        //对图片进行压缩
        //判断list中有多少图片
        System.out.println(voList);
        if (voList != null && voList.size() > 0) {
            /*批量下载*/
            try {
                String downloadFilename = "";
                String NowTimeString = String.valueOf(System.currentTimeMillis());
                downloadFilename = "报名.zip";//压缩包文件的名称
                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 < voList.size(); i++) {
                    if (voList.get(i) != null) {
                        zos.putNextEntry(new ZipEntry(voList.get(i).getUserName()+voList.get(i).getPhone()+ ".jpg"));
                        url = voList.get(i).getFileUrl();
                        //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();
                            }
                        } else {
                            System.out.println("为空");
                        }
                    }
                }
                zos.flush();
                zos.close();
            } catch (Exception e) {
                e.printstacktrace();
            }
        }

        //删除当前文件夹中所有文件
        //File basefile = new File("/usr/share/study/mbZip/");   //path为给定的文件夹地址
        //remove(basefile);
    }



    /**
     * 删除指定文件夹下的全部内容
     * @param file
     */
    public static void remove(File file) {
        File[] files = file.listFiles();//将file子目录及子文件放进文件数组
        if (files != null) {//如果包含文件进行删除操作
            for (int i = 0; i < files.length; i++) {
                if (files[i].isFile()) {//删除子文件
                    files[i].delete();
                } else if (files[i].isDirectory()) {//通过递归方法删除子目录的文件
                    remove(files[i]);
                }
                files[i].delete();//删除子目录
            }
        }
    }


}

    private String fileUrl;
