今天写了个文本编辑器，借助ckeditor感觉还行，放到网上，大家一起分享爱一下。

首先是页面部分，只需引入ckeditor.js文件即可（通过文本编辑器写出来的动西后，最后通过html显示出来）。

写道

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>editor(文本编辑器)</title>
<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
</head>
<body>
<form action="/Project_learn/EditorServlet" method="post">
<p><input type="text" name="title" /></p>
<p><textarea name="contents"></textarea></p>
<p><input type="submit" value="发布"/></p>
</form>
<script type="text/javascript">
CKEDITOR.replace( 'contents' );
</script>

</body>
</html>

其次是服务端，获取html中输入的信息，然后通过网页形式显示出来。同时把生成的网页保存在/blog/ 文件夹中。
package com.erong.project.web;
