先做一個html模板
[code]
<html>
<head>
<title>#####title#####</title>
</head>
<body>
name:#####name#####
age:#####age#####
</body>
</html>
[/code]
再寫一個類來生成 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+位隨機數)
/***
*
*/
public String[] replace(HashMap hash,String path) throws IOException {
try {
String HtmlTemplate;
//把HtmlTemplate讀到流裏
FileInputStream fileinputstream = new FileInputStream(fileName);
//得到讀取字節數
int length = fileinputstream.available();
byte[] bytes = new byte[length];
//把輸入流字節放入bytes
fileinputstream.read(bytes);
fileinputstream.close();
//把字節轉成String
HtmlTemplate = new String(bytes);
//取出鍵值
Set set = hash.keySet();
Object[] obj = set.toArray();
for (int i = 0; i < obj.length; i++) {
System.out.println(obj[i]);
}
//替換流
for(int i=0;i<hash.size();i++){
//替換標記
//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;
//驗證是否有相同KEY
//產生文件名
filename = FileUtil.getFileNameKey();
//filename是htmlkey
//HtmlTemplate=HtmlTemplate.replaceAll(HTMLKEY,filename);
String filenametwo = filename + ".html";
//建立輸出流
FileOutputStream outStream = new FileOutputStream(path+filenametwo);
//把替換後的HtmlTemplate輸出
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#####","測試");
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]
/***
* 創建日期文件名
* @return
*/
public String getDateFileName(){
//獲取今天的年,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]
