為了減輕服務(wù)器壓力，將原來(lái)的文章管理系統(tǒng)由JSP文件的從數(shù)據(jù)庫(kù)中取數(shù)據(jù)顯示改為由jsp生成靜態(tài)html文件后直接訪問html文件。首先應(yīng)創(chuàng)建一個(gè)模板文件，文件名和文件后綴可以隨意，但我一般常用的還是 *.template ，因此，這里就以 template.template 為例( 將模板文件放入 /WEB-INF/templates/ 文件夾下 )：下面是一個(gè)簡(jiǎn)單的示例
1.buildhtml.jsp
Jsp代碼
<%@ page contentType="text/html; charset=gb2312" import="java.util.*,java.io.*"%>
<%
try{
//設(shè)置字符編碼
request.setCharacterEncoding( "gb2312" );
response.setCharacterEncoding( "gb2312" );
String title="This is Title";
String content="This is Content Area";
String editer="LaoMao";
String filePath = "";
// 獲得模板文件的路徑
filePath = request.getRealPath("/")+"test/template.htm";
//out.print(filePath+"<br>");
String templateContent="";
//讀取模塊文件
FileInputStream fileinputstream = new FileInputStream(filePath);
int lenght = fileinputstream.available();
byte bytes[] = new byte[lenght];
fileinputstream.read(bytes);
fileinputstream.close();
templateContent = new String(bytes);
//out.print(templateContent);
templateContent=templateContent.replaceAll("###title###",title);
templateContent=templateContent.replaceAll("###content###",content);
templateContent=templateContent.replaceAll("###author###",editer);//替換掉模塊中相應(yīng)的地方
//out.print(templateContent);
// 根據(jù)時(shí)間得文件名
Calendar calendar = Calendar.getInstance();
String fileame = String.valueOf(calendar.getTimeInMillis()) +".html";
//生成的html文件保存路徑
fileame = request.getRealPath("/")+fileame;
//建立文件輸出流
FileOutputStream fileoutputstream = new FileOutputStream(fileame);
byte tag_bytes[] = templateContent.getBytes();
fileoutputstream.write(tag_bytes);
fileoutputstream.close();
}catch(Exception e){
out.print(e.toString());
}
%>
<%@ page contentType="text/html; charset=gb2312" import="java.util.*,java.io.*"%>
<%
try{
//設(shè)置字符編碼
request.setCharacterEncoding( "gb2312" );
response.setCharacterEncoding( "gb2312" );
String title="This is Title";
String content="This is Content Area";
String editer="LaoMao";
String filePath = "";
// 獲得模板文件的路徑
filePath = request.getRealPath("/")+"test/template.htm";
//out.print(filePath+"<br>");
String templateContent="";
//讀取模塊文件
FileInputStream fileinputstream = new FileInputStream(filePath);
int lenght = fileinputstream.available();
byte bytes[] = new byte[lenght];
fileinputstream.read(bytes);
fileinputstream.close();
templateContent = new String(bytes);
//out.print(templateContent);
templateContent=templateContent.replaceAll("###title###",title);
templateContent=templateContent.replaceAll("###content###",content);
templateContent=templateContent.replaceAll("###author###",editer);//替換掉模塊中相應(yīng)的地方
//out.print(templateContent);
// 根據(jù)時(shí)間得文件名
Calendar calendar = Calendar.getInstance();
String fileame = String.valueOf(calendar.getTimeInMillis()) +".html";
//生成的html文件保存路徑
fileame = request.getRealPath("/")+fileame;
//建立文件輸出流
FileOutputStream fileoutputstream = new FileOutputStream(fileame);
byte tag_bytes[] = templateContent.getBytes();
fileoutputstream.write(tag_bytes);
fileoutputstream.close();
}catch(Exception e){
out.print(e.toString());
}
%>
2. template.template
Html代碼
<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###</td>
</tr>
<tr>
<td align="center">author：###author### </td>
</tr>
<tr>
<td>###content###
</td>
</tr>
</table>
</body>
</html>
<html>
<head>
<title>###title###</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

</table>
</body>
</html>
為了將應(yīng)用進(jìn)行國(guó)際化，可以將頁(yè)面的編碼設(shè)為 UTF-8
1.buildhtml.jsp
<%@ page contentType="text/html; charset=gb2312" import="java.util.*,java.io.*"%>
<%
try{
String title="This is Title";
String content="This is Content Area";
String editer="LaoMao";
String filePath = "";
filePath = request.getRealPath("/")+"test/template.htm";
//out.print(filePath+"<br>");
String templateContent="";
FileInputStream fileinputstream = new FileInputStream(filePath);//讀取模塊文件
int lenght = fileinputstream.available();
byte bytes[] = new byte[lenght];
fileinputstream.read(bytes);
fileinputstream.close();
templateContent = new String(bytes);
//out.print(templateContent);
templateContent=templateContent.replaceAll("###title###",title);
templateContent=templateContent.replaceAll("###content###",content);
templateContent=templateContent.replaceAll("###author###",editer);//替換掉模塊中相應(yīng)的地方
//out.print(templateContent);
// 根據(jù)時(shí)間得文件名
Calendar calendar = Calendar.getInstance();
String fileame = String.valueOf(calendar.getTimeInMillis()) +".html";
fileame = request.getRealPath("/")+fileame;//生成的html文件保存路徑
FileOutputStream fileoutputstream = new FileOutputStream(fileame);//建立文件輸出流
byte tag_bytes[] = templateContent.getBytes();
fileoutputstream.write(tag_bytes);
fileoutputstream.close();
}
catch(Exception e){
out.print(e.toString());
}
%>
2. 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>
