CKEditor 上傳文件後返回的內容

注意針對SpringMvc模式

1、修改ckeditor 的配置文件 config.js

config.filebrowserUploadUrl = "fileUpload.html?type=Files&filePath=ckeditor";//上傳文件的保存路徑
	config.filebrowserImageUploadUrl = 'fileUpload.html?type=Images&filePath=ckeditor';//上傳圖片的保存路徑
	config.filebrowserFlashUploadUrl = 'fileUpload.html?type=Flash&filePath=ckeditor';//上傳flash的保存路徑

2、編寫文件上傳接受控制器

/**
	 * CKEDITOR 插件文件上傳
	 * @param request
	 * @param response
	 * @return
	 */
	@RequestMapping(value = "fileUpload.html")
	@ResponseBody
	public String processImageUpload(HttpServletRequest request,HttpServletResponse response) {
		String callback = request.getParameter("CKEditorFuncNum");
		Site site = this.getCurrentSite();
		String urlPrefix = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort();
		request.getRequestURI();
		CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext());
		MultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext());
		commonsMultipartResolver.setDefaultEncoding("utf-8");
		Map mapPath=new HashMap();
		try {
			response.setContentType("text/html; charset=UTF-8");
            response.setHeader("Cache-Control", "no-cache");
            PrintWriter out = response.getWriter();
			site = siteService.getSite(site.getSiteId());
			if (commonsMultipartResolver.isMultipart(request)) {
				MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request);
				Iterator<String> iter = multipartRequest.getFileNames();
				while (iter.hasNext()) {
					MultipartFile file = multipartRequest.getFile((String) iter.next());
					System.out.println(file.getName());
					//文件上傳機制包含重名
					mapPath = this.disposeFilePath(file,site,null,true,false,false);
				}
				if(StringUtils.isEmpty(mapPath.get("imageurl").toString())){
					String imgPath = urlPrefix + mapPath.get("imageurl");
					out.println("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(" + callback+ ",'" + imgPath + "','圖片上傳失敗'" + ")"+"</script>");
				}else{
					String imgPath = urlPrefix + mapPath.get("imageurl");
					out.println("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(" + callback+ ",'" + imgPath + "',''" + ")"+"</script>");
				}
				out.flush();
		        out.close();
			}
			
		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
	}

某些環境下在獲取 iter文件出現空

Iterator<String> iter = multipartRequest.getFileNames();

可以試試

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
Iterator<String> iter = multipartRequest.getFileNames();
