写这篇文章前必须的感谢一下

之前在测试的时候遇到一个IE不兼容的问题,就是这位大神帮忙解决的。
在把springmvc和KindEditor整合的时候主要是重写了KindEditor中的file_manager_json.jsp和upload_json.jsp
用springmvc的两个action替代了。
在这个整合的实例中没的上传功能用的不是springmvc特制的。
处理文件上传的代码如下:
@RequestMapping(value = "file_upload.do", method = RequestMethod.POST) public void fileUpload(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException, FileUploadException { ServletContext application = request.getSession().getServletContext(); String savePath = application.getRealPath("/") + "attached/"; // 文件保存目录URL String saveUrl = request.getContextPath() + "/attached/"; // 定义允许上传的文件扩展名 HashMap<String, String> extMap = new HashMap<String, String>(); extMap.put("image", "gif,jpg,jpeg,png,bmp"); extMap.put("flash", "swf,flv"); extMap.put("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb"); extMap.put("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2"); // 最大文件大小 long maxSize = 1000000; response.reset(); response.setCharacterEncoding("UTF-8"); response.setContentType("text/html"); writer = response.getWriter(); // writer.println(json); //想办法把map转成json if (!ServletFileUpload.isMultipartContent(request)) { writer.println(objectMapper.writeValueAsString(getError("请选择文件。"))); return; } // 检查目录 File uploadDir = new File(savePath); if (!uploadDir.isDirectory()) { writer.println(objectMapper.writeValueAsString(getError("上传目录不存在。"))); return; } // 检查目录写权限 if (!uploadDir.canWrite()) { writer.println(objectMapper.writeValueAsString(getError("上传目录没有写权限。"))); return; } String dirName = request.getParameter("dir"); if (dirName == null) { dirName = "image"; } if (!extMap.containsKey(dirName)) { writer.println(objectMapper.writeValueAsString(getError("目录名不正确。"))); return; } // 创建文件夹 savePath += dirName + "/"; saveUrl += dirName + "/"; File saveDirFile = new File(savePath); if (!saveDirFile.exists()) { saveDirFile.mkdirs(); } SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd"); String ymd = sdf.format(new Date()); savePath += ymd + "/"; saveUrl += ymd + "/"; File dirFile = new File(savePath); if (!dirFile.exists()) { dirFile.mkdirs(); } FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); upload.setHeaderEncoding("UTF-8"); List items = upload.parseRequest(request); Iterator itr = items.iterator(); while (itr.hasNext()) { FileItem item = (FileItem) itr.next(); String fileName = item.getName(); if (!item.isFormField()) { // 检查文件大小 if (item.getSize() > maxSize) { writer.println(objectMapper.writeValueAsString(getError("上传文件大小超过限制。"))); } // 检查扩展名 String fileExt = fileName.substring( fileName.lastIndexOf(".") + 1).toLowerCase(); if (!Arrays.<String> asList(extMap.get(dirName).split(",")) .contains(fileExt)) { writer.println(objectMapper.writeValueAsString(getError("上传文件扩展名是不允许的扩展名。\n只允许"+ extMap.get(dirName) + "格式。"))); return; } SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss"); String newFileName = df.format(new Date()) + "_" + new Random().nextInt(1000) + "." + fileExt; try { File uploadedFile = new File(savePath, newFileName); item.write(uploadedFile); } catch (Exception e) { writer.println(objectMapper.writeValueAsString(getError("上传文件失败。"))); } Map<String, Object> msg = new HashMap<String, Object>(); msg.put("error", 0); msg.put("url", saveUrl + newFileName); writer.println(objectMapper.writeValueAsString(msg)); return; } } return; }
处理服务器文件浏览的代码如下:
@RequestMapping(value = "file_manager.do", method = RequestMethod.GET) public void fileManager(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ServletContext application = request.getSession().getServletContext(); ServletOutputStream out = response.getOutputStream(); // 根目录路径,可以指定绝对路径,比如 /var/www/attached/ String rootPath = application.getRealPath("/") + "attached/"; // 根目录URL,可以指定绝对路径,比如 http://www.yoursite.com/attached/ String rootUrl = request.getContextPath() + "/attached/"; // 图片扩展名 String[] fileTypes = new String[] { "gif", "jpg", "jpeg", "png", "bmp" }; String dirName = request.getParameter("dir"); if (dirName != null) { if (!Arrays.<String> asList( new String[] { "image", "flash", "media", "file" }) .contains(dirName)) { out.println("Invalid Directory name."); return; } rootPath += dirName + "/"; rootUrl += dirName + "/"; File saveDirFile = new File(rootPath); if (!saveDirFile.exists()) { saveDirFile.mkdirs(); } } // 根据path参数,设置各路径和URL String path = request.getParameter("path") != null ? request .getParameter("path") : ""; String currentPath = rootPath + path; String currentUrl = rootUrl + path; String currentDirPath = path; String moveupDirPath = ""; if (!"".equals(path)) { String str = currentDirPath.substring(0, currentDirPath.length() - 1); moveupDirPath = str.lastIndexOf("/") >= 0 ? str.substring(0, str.lastIndexOf("/") + 1) : ""; } // 排序形式,name or size or type String order = request.getParameter("order") != null ? request .getParameter("order").toLowerCase() : "name"; // 不允许使用..移动到上一级目录 if (path.indexOf("..") >= 0) { out.println("Access is not allowed."); return; } // 最后一个字符不是/ if (!"".equals(path) && !path.endsWith("/")) { out.println("Parameter is not valid."); return; } // 目录不存在或不是目录 File currentPathFile = new File(currentPath); if (!currentPathFile.isDirectory()) { out.println("Directory does not exist."); return; } // 遍历目录取的文件信息 List<Hashtable> fileList = new ArrayList<Hashtable>(); if (currentPathFile.listFiles() != null) { for (File file : currentPathFile.listFiles()) { Hashtable<String, Object> hash = new Hashtable<String, Object>(); String fileName = file.getName(); if (file.isDirectory()) { hash.put("is_dir", true); hash.put("has_file", (file.listFiles() != null)); hash.put("filesize", 0L); hash.put("is_photo", false); hash.put("filetype", ""); } else if (file.isFile()) { String fileExt = fileName.substring( fileName.lastIndexOf(".") + 1).toLowerCase(); hash.put("is_dir", false); hash.put("has_file", false); hash.put("filesize", file.length()); hash.put("is_photo", Arrays.<String> asList(fileTypes) .contains(fileExt)); hash.put("filetype", fileExt); } hash.put("filename", fileName); hash.put("datetime", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(file .lastModified())); fileList.add(hash); } } if ("size".equals(order)) { Collections.sort(fileList, new SizeComparator()); } else if ("type".equals(order)) { Collections.sort(fileList, new TypeComparator()); } else { Collections.sort(fileList, new NameComparator()); } Map<String, Object> msg = new HashMap<String, Object>(); msg.put("moveup_dir_path", moveupDirPath); msg.put("current_dir_path", currentDirPath); msg.put("current_url", currentUrl); msg.put("total_count", fileList.size()); msg.put("file_list", fileList); response.setContentType("application/json; charset=UTF-8"); String msgStr = objectMapper.writeValueAsString(msg); out.println(msgStr); }
