首先，我們需要一個html模板：
-
<html>
-
<head>
-
<title>###title###</title>
-
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
-
</head>
-
-
<body>
-
<table width="500" border="0" align="center" cellpadding="0" cellspacing="2">
-
<tr>
-
<td align="center">###title###</td>
-
</tr>
-
<tr>
-
<td align="center">###author### </td>
-
</tr>
-
<tr>
-
<td>###content###</td>
-
</tr>
-
<tr>
-
<td>###html###</td>
-
</tr>
-
-
</table>
-
</body>
-
</html>
其次：我們編寫java代碼實現模板讀取，頁面生成：
-
import javax.servlet.http.HttpServletRequest;
-
import java.util.List;
-
import java.util.ArrayList;
-
import java.util.Date;
-
import java.net.URL;
-
import java.net.URLConnection;
-
import java.io.*;
