ckeditor 图片上传最新完美处理

需要做的有以下几步：
1. 到官网下载ckeditor，网址：http://ckeditor.com/download
2. 复制到java web项目目录下
3. 配置config文件，打开图片上传功能
   

CKEDITOR.editorConfig = function (config) {
// 换行方式
	config.enterMode = CKEDITOR.ENTER_BR;

	// 当输入：shift+Enter是插入的标签
	config.shiftEnterMode = CKEDITOR.ENTER_BR;// 
	//图片处理
	config.pasteFromWordRemoveStyles = true;
	config.filebrowserImageUploadUrl = "ckUploadImage.action?type=image";
	
	// 去掉ckeditor“保存”按钮
	config.removePlugins = 'save';
};

** 在这里另附flex引用ckeditor 编辑器默认全屏方法：
修改ckeditor.html页面：

<script type="text/javascript">
		if ( typeof CKEDITOR == 'undefined' )
		{
		  document.write('加载失败') ;
		}
		else
		{
		  //var editor = CKEDITOR.replace( 'editor1',
		  //     {
			//		customConfig: "news_ck_config.js"
		//		});
		 
		  var editor = CKEDITOR.replace( 'editor1');
				
		  CKEDITOR.on('instanceReady', function(evt){
	         var editor = evt.editor;
	         editor.execCommand('maximize');
	      });
		}

</script>

4. java后台处理代码

// 上传图片
	@Action(value = "/ckUploadImage", results = { @Result(name = "success", location = "/upload.jsp") })
	public String uploadImages() throws Exception {
		HttpServletRequest request = ServletActionContext.getRequest();
		FileOutputStream fos;
		String webRoot = request.getSession().getServletContext().getRealPath(
				"");
		// 获取图片后缀名
		String partRightType = uploadFileName.substring(uploadFileName
				.lastIndexOf("."));
		String CKEditorFuncNum = request.getParameter("CKEditorFuncNum");
		// 判断图片的格式
		if (!ImageFile.checkImageType(partRightType)) {
			String path = "";
			String alt_msg = "Sorry! Image format selection is incorrect, please choose GIF, jpeg, PNG format JPG, picture!";
			pringWriterToPage("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("
					+ CKEditorFuncNum
					+ ", '"
					+ path
					+ "' , '"
					+ alt_msg
					+ "');</script>");
		} else {
			try {

				uploadFileName = DateUtils.getDateNoStyle() + "-"
						+ UUID.randomUUID() + partRightType;

				String savePath = webRoot + Constants.UPLOAD_IMAGES_PATH;
				File uploadFilePath = new File(savePath);
				if (uploadFilePath.exists() == false) {
					uploadFilePath.mkdirs();
					System.out.println("路径不存在,但是已经成功创建了" + savePath);
				} else {
					System.out.println("路径存在了" + savePath);
				}
				fos = new FileOutputStream(new File(savePath + uploadFileName));
				FileInputStream fis = new FileInputStream(getUpload());
				byte[] buffer = new byte[1024];
				int len = 0;
				while ((len = fis.read(buffer)) > 0) {
					fos.write(buffer, 0, len);
				}
				fos.close();
				fis.close();
			} catch (FileNotFoundException foe) {
				System.out.println("上传文件为0字节");
			}

			// String path = "http://" + request.getServerName() + ":"
			// + request.getServerPort() + request.getContextPath()
			// + Constants.UPLOAD_IMAGES_PATH + uploadFileName;

			String path = request.getContextPath()
					+ Constants.UPLOAD_IMAGES_PATH + uploadFileName;
			String alt_msg = "";
			pringWriterToPage("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("
					+ CKEditorFuncNum
					+ ", '"
					+ path
					+ "' , '"
					+ alt_msg
					+ "');</script>");

		}

		return null;
	}

* 其实重点的代码就是这点，相信大家都能看的懂，有不懂的留言！
pringWriterToPage("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("
+ CKEditorFuncNum
+ ", '"
+ path
+ "' , '"
+ alt_msg
+ "');</script>");

怎么样才能让这个javascript在页面执行？
字符串返回后页面要处理过的吧？

3 楼 zjut_jing 2011-05-25  

pringWriterToPage这个函数的代码能写一下吗？

pringWriterToPage("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(" 
                    + CKEditorFuncNum 
                    + ", '" 
                    + path 
                    + "' , '" 
                    + alt_msg 
                    + "');</script>"); 
  没明白

这个的意思就是上传成功后把图片添加到那个预览框里面！
