先做一个html模板
[code]
<html>

<head>
<title>#####title#####</title>
</head>

<body>

name:#####name#####
age:#####age#####
</body>

</html>
[/code]

再写一个类来生成 html

[code]package com.huaying;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.HashMap;
import java.util.Random;
import java.util.Set;

import javax.servlet.http.HttpServletRequest;

public class HtmlModelUtil {

private final static String TAGTOP = "#####";

private final static String TAGFINALITY = "#####";

private final String fileName;

public HtmlModelUtil(String filename){
this.fileName = filename;
}

//返回文件名(yyyyMMddhhmmss+位随机数)
/***
*
*/
public String[] replace(HashMap hash,String path) throws IOException {
try {
String HtmlTemplate;
//把HtmlTemplate读到流里
FileInputStream fileinputstream = new FileInputStream(fileName);

//得到读取字节数
int length = fileinputstream.available();
byte[] bytes = new byte[length];
//把输入流字节放入bytes
fileinputstream.read(bytes);
fileinputstream.close();

//把字节转成String
HtmlTemplate = new String(bytes);

//取出键值
Set set = hash.keySet();
Object[] obj = set.toArray();

for (int i = 0; i < obj.length; i++) {

System.out.println(obj[i]);
}
//替换流
for(int i=0;i<hash.size();i++){
//替换标记
//System.out.println(this.TAGTOP+obj[i].toString()+this.TAGFINALITY);
//System.out.println((String)hash.get(obj[i]));
if(hash.get(obj[i])!=null)
HtmlTemplate=HtmlTemplate.replaceAll(obj[i].toString(),(String)hash.get(obj[i]));
}

System.out.println(HtmlTemplate);

String filename = null;
//验证是否有相同KEY

//产生文件名
filename = FileUtil.getFileNameKey();

//filename是htmlkey
//HtmlTemplate=HtmlTemplate.replaceAll(HTMLKEY,filename);

String filenametwo = filename + ".html";

//建立输出流
FileOutputStream outStream = new FileOutputStream(path+filenametwo);
//把替换后的HtmlTemplate输出
outStream.write(HtmlTemplate.getBytes());

outStream.flush();
outStream.close();

String[] str = new String[2];
str[0] = filename;
str[1] = filenametwo;

return str;
} catch (Exception e) {
e.printStackTrace();
return null;
}

}

public static void main(String[] args) {

HtmlModelUtil hmu = new HtmlModelUtil("E:/51photo/WebRoot/text.html");
HashMap hash = new HashMap();
hash.put("#####title#####","测试");
hash.put("#####name#####","penghao");
hash.put("#####age#####","21");

try {
System.out.println(hmu.replace(hash,"E://"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}[/code]

[code]
/***
* 创建日期文件名
* @return
*/
public String getDateFileName(){
//获取今天的年,月,日
Date d = new Date();
int year = d.getYear()+YEARADD;
int month = d.getMonth()+MONTHADD;
int date = d.getDate();

Random random = new Random();

String fileName = year+""+month+""+date+""+random.nextLong();

return fileName;
}
[/code]
