Jsp中怎么把数据从数据库导出在页面直接生成html格式??

先建立一个模板页面:template.htm 
<html><head><title>###title###</title> 
<meta http- equiv="Content-Type" content="text/html; charset=gb2312"> 
<LINK href="../css.css" rel=stylesheet type=text/css></head> 
<body> 
<table width="500" border="0" align="center" cellpadding="0" cellspacing="2"> 
<tr><td align="center">###title###</tr> 
<tr><td align="center">作者:###author###</tr> 
<tr><td align="center">###content###</td></tr> 
</table> 
</body> 
</html> 

再写一个Java页面: buildhtml.java: 

import java.util.*; 
import java.io.*; 
public class HtmlFile{ 
public static void main(String[] args){ 
try{ 
String title="Make Html"; 
String content="小样,还搞不定你?"; 
String editer="Hulihutu"; 
String filePath = ""; 
filePath ="template.html"; 
System.out.print(filePath); 
String templateContent=""; 
FileInputStream fileinputstream = new FileInputStream(filePath);// 读取模板文件 
int lenght = fileinputstream.available(); 
byte bytes[] = new byte[lenght]; 
fileinputstream.read(bytes); 
fileinputstream.close(); 
templateContent = new String(bytes); 
System.out.print(templateContent); 
templateContent=templateContent.replaceAll("###title###",title); 
templateContent=templateContent.replaceAll("###content###",content); 
templateContent=templateContent.replaceAll("###author###",editer);// 替换掉模板中相应的地方 
System.out.print(templateContent); 

// 根据时间得文件名 
Calendar calendar = Calendar.getInstance(); 
String fileame = String.valueOf(calendar.getTimeInMillis()) +".html"; 
fileame = "/" + fileame;// 生成的html文件保存路径。 
FileOutputStream fileoutputstream = new FileOutputStream(fileame);// 建立文件输出流 
System.out.print("文件输出路径:"); 
System.out.print(fileame); 
byte tag_bytes[] = templateContent.getBytes(); 
fileoutputstream.write(tag_bytes); 
fileoutputstream.close(); 
}catch(Exception e){ 
System.out.print(e.toString()); 
} 
} 
}
