在頁面或者後台response,直接用文件頭加你的文件，文件流寫出。 比如在頁面這樣寫,當然，最好在後台寫: <%@ page language="java" import="java.util.*" pageEncoding="gbk"%> <% 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 'test.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> <% // 得到文件名字和路徑 String filename = "Example.zip"; String filepath = "D:\\"; // 設置響應頭和下載保存的文件名 response.setContentType("APPLICATION/OCTET-STREAM"); response.setHeader("Content-Disposition", "attachment; filename=\"" + filename + "\""); // 打開指定文件的流信息 java.io.FileInputStream fileInputStream = new java.io.FileInputStream(filepath + filename); // 寫出流信息 int i; while ((i=fileInputStream.read()) != -1) { out.write(i); } fileInputStream.close(); out.close(); %> </body> </html>
