原理都很簡單,主要是對模板的解析.so,我們先准備一個html模板
mb.html,做個文件其中的###title###之類的標簽用於程序進行查詢替換.
- HTML code 復制代碼
-
<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>
下面是具體的代碼:JspToHtml.java
- Java code 復制代碼
