原理都很简单,主要是对模板的解析.so,我们先准备一个html模板
mb.html,做个文件其中的###title###之类的标签用于程序进行查询替换.
- HTML code复制代码
-
<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>
下面是具体的代码:JspToHtml.java
