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"> </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(); %>
