为了减轻服务器压力，将原来的文章管理系统由JSP文件的从数据库中取数据显示改为由jsp生成静态html文件后直接访问html文件。下面是一个简单的示例
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);//读取模块文件 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);//替换掉模块中相应的地方 //out.print(templateContent); // 根据时间得文件名 Calendar calendar = Calendar.getInstance(); String fileame = String.valueOf(calendar.getTimeInMillis()) +".html"; fileame = request.getRealPath("/")+fileame;//生成的html文件保存路径 FileOutputStream fileoutputstream = new FileOutputStream(fileame);//建立文件输出流 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></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>
