SpringMVC+Ajax实现文件批量上传和下载功能实例代码_AJAX相关_

 controller： /* * 上传多个文件 */ @RequestMapping(value = "/upload", produces = "application/json;charset=UTF-8") public @ResponseBody boolean uploadFiles(@RequestParam("file_upload") MultipartFile [] files) { boolean result = false; String realPath; for(int i=0;i

 /* * 下载多个文件 */ @RequestMapping(value = "/download") public void downloadFiles(HttpServletResponse response) { String str= request.getParameter("rows");//下载文件信息，包括文件名、存储路径等 JSONArray path=(JSONArray) JSONArray.parse(request.getParameter("rows")); Path paths[]=new Path[path.size()]; paths = JSONArray.parseArray(str, Path.class).toArray(paths); String uri = "d:"+ File.separator + "mldn.zip";//临时文件存储路径 File zipFile = new File(uri) ; // 定义压缩文件名称 ZipOutputStream zipOut = null;// 声明压缩流对象 InputStream input = null; //将要压缩的文件加入到压缩输出流中 try { zipOut = new ZipOutputStream(new FileOutputStream(zipFile)); } catch (FileNotFoundException e) { e.printStackTrace(); } for(int i = 0;i
 function download(){ var form=$("
");//定义一个form表单 form.attr("style","display:none"); form.attr("target",""); form.attr("method","post"); form.attr("action","./path/download");//请求url var input1=$(""); input1.attr("type","hidden"); input1.attr("name","rows");//设置属性的名字 input1.attr("value",“test”);//设置属性的值 $("body").append(form);//将表单放置在web中 form.append(input1); form.submit();//表单提交 }
