最近看到很多人要将网页保存成word格式，

所以就试了下使用POI来讲网页保存成word

基本思路就是在网页提交时，把整个页面的源文件提交到后台，然后写入word中

下面是一个简单的示例，可以参考下

首先看JSP页面，像下面这样

<%@ page language="java" import="java.util.*" pageEncoding="utf-8" contentType="text/html; charset=utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>jsp转word</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </head>
  
  <body>
    <img alt="ss" src="0.jpg">
    <table border="1" width="80%">
    	<tr>
    		<td>1</td>
    		<td>2</td>
    		<td>3</td>
    		<td>4</td>
    		<td>5</td>
    		<td>6</td>
    		<td>7</td>
    		<td>8</td>
    		<td>9</td>
    		<td>0</td>
    	</tr>
    	<tr>
    		<td>1</td>
    		<td>2</td>
    		<td>3</td>
    		<td>4</td>
    		<td>5</td>
    		<td>6</td>
    		<td>7</td>
    		<td>8</td>
    		<td>9</td>
    		<td>0</td>
    	</tr>
    	<tr>
    		<td>1</td>
    		<td>2</td>
    		<td>3</td>
    		<td>4</td>
    		<td>5</td>
    		<td>6</td>
    		<td>7</td>
    		<td>8</td>
    		<td>9</td>
    		<td>0</td>
    	</tr>    	    	
    </table>
    <p>
    	这是个测试页面，用来把jsp页面转换成word
    </p>
    <div style="color: red;">
    	红色的字呀
    </div>
    <div style="width: 100px;height: 100px;background-color: yellow;">
    	黄色的背景呀
    </div>
    <form action="servlet/exportServlet" method="post">
    	<input type="hidden" name="html"/>
    	<input type="button" οnclick="saveAsWord()" value="保存">
    </form>
  </body>
  <script type="text/javascript">
  	function saveAsWord(){
  		var f = document.forms[0];
  		f.html.value = document.documentElement.innerHTML;
  		f.submit();
  	}
  </script>
</html>

这样页面的效果如下

看下serlvet的代码

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
			request.setCharacterEncoding("utf-8");
			response.setCharacterEncoding("utf-8");		
			request.setAttribute("text", "request");
			String html = request.getParameter("html");
			if(html != null){
				byte[] bs = html.getBytes();
				ByteArrayInputStream bais = new ByteArrayInputStream(bs);
				POIFSFileSystem poifs = new POIFSFileSystem();
				DirectoryEntry directory = poifs.getRoot();  
				DocumentEntry documentEntry = directory.createDocument("WordDocument", bais);
				FileOutputStream ostream = new FileOutputStream("D:\\word.doc");
				poifs.writeFilesystem(ostream);
                bais.close();  
                ostream.close();				
			}
			request.getRequestDispatcher("/index.jsp").include(request, response);
	}

打开生成的word会看到下面这么
