CKEditor配置以及上传图片附件

配置config.js

添加 其中的url指向的都是上传的方法 action或者servlet 图片浏览则会跳转到一个新的页面 选择上传

// 图片上传配置  
config.filebrowserImageUploadUrl = 'upload.do?type=Image';
// flash上传配置
config.filebrowserFlashUploadUrl = 'upload.do?type=Flash';
	
// 图片浏览配置
config.filebrowserUploadUrl = 'upload.do?type=File'; 
config.filebrowserImageBrowseUrl = 'browerServer.do?type=image';

写一个图片上传的servlet

然后测试页面 如果上传之后跳转到了图片属性页面 那就是成功了

最后在servlet的后面加上CKEditor的callback回调函数 返回图片的地址给CKEditor实现图片的预览

String callback = request.getParameter("CKEditorFuncNum");
		out.println("<script type=\"text/javascript\">");
		out.println("window.parent.CKEDITOR.tools.callFunction(" + callback
				+ ",'" + remotefilePath + "',''" + ")");
		out.println("</script>");
		out.flush();
		out.close();

以下为一个上传的servlet的demo.返回的是完整的地址 即包含了 http://yourserver:port/servername/的远程地址
