Java读取根据HTML模板生成HTML页面

2018-01-23 10:58 381 查看

首先，我们需要一个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：我们编写java代码实现模板读取，页面生成：

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.*;

e.printStackTrace();
return false;
}
try {

str = str.replaceAll("###title###",title);
 str = str.replaceAll("###content###",context);
 str = str.replaceAll("###author###",editer);//替换掉模块中相应的地方
