java多文件以压缩文件夹的方式导出

java多文件以压缩文件夹的方式导出

多文件导出的时候，不是一个个导出。把多个文件放到一个压缩文件夹里面，直接导出压缩文件夹

一、前端多选文件

function DownAll() {//hdIdValue 为多文件的路径，以逗号分开var hdIdValue = $("#hdIdValue").val();if(hdIdValue=="")alert("请选择数据！");elselocation.href = "downloadFiles.do?recordpath="+window.encodeURI(hdIdValue);
}

二、downloadFiles.do后端代码

public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {req.setCharacterEncoding("UTF-8");String recordpathss=req.getParameter("recordpath");//传过来的路径们，以逗号分开String[] recordpaths=recordpathss.split(",");try {String downloadFilename = URLEncoder.encode("录音文件_"+String.valueOf(System.currentTimeMillis())+".zip", "UTF-8");ZipOutputStream zos = new ZipOutputStream(resp.getOutputStream());FileInputStream ips = null;File file = new File("");byte[] buffer = new byte[1024];int r = 0;resp.setContentType("application/octet-stream");resp.setHeader("Content-Disposition", "attachment;filename=\""+downloadFilename+"\"");for(int i=0;i<recordpaths.length;i++) {String filename = recordpaths[i].split("/")[recordpaths[i].split("/").length-1];zos.putNextEntry(new ZipEntry(filename));file = new File (recordpaths[i]);if(file.exists()){ips = new FileInputStream(file);resp.setContentType("multipart/form-data");while ((r = ips.read(buffer)) != -1) {zos.write(buffer, 0, r);}if (null != ips) {ips.close();}}else{logger.info(filename+"@@@找不到文件");}}zos.flush();zos.close();} catch (Exception e) {e.printStackTrace();}}
