解密pdf-2(在线动态创建并自动下载pdf文件)

这里使用的jsp
采用动态创建方式进行在线生成和下载
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'index.jsp' starting page</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </head>
  
  <body>
    This is my JSP page. <br>
    <form action="out.jsp" method="post">
    	name : <input type="text" name="tname"><br>
    	<input type="submit">
    </form>
  </body>
</html>


没什么说得 一个表单提交页

呵呵 下面的是重点 文件生成页
<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
<%@ page language="java" import="java.util.*"%>
<%@ page language="java" import="com.lowagie.text.*,com.lowagie.text.pdf.*"%>
<%@ page language="java" import="java.io.*"%>
<%
	response.reset();
	//创建文件头信息
	response.setContentType("application/x-msdownload");  
	response.setHeader("Content-Disposition",   "attachment;   filename="+new String(("hello"+request.getParameter("tname")+".pdf").getBytes(),"iso8859-1"));  
	//文件输出流
	ServletOutputStream sos = response.getOutputStream();  
	Document doc = new Document();
	PdfWriter.getInstance(doc, sos);  
	doc.open();  
	doc.add(new Paragraph("Hello "+request.getParameter("tname")+" !"));  
	doc.close();
	//关闭
	sos.flush();
	sos.close();
	out.clear();
	out = pageContext.pushBody();
 %>
