javaweb實驗---Struts2框架開發應用
upload.html:
<html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>簡單的檔案上傳</title> </head> <body> <form action="upload.action" method="post" enctype="multipart/form-data"> 檔案標題：<input type="text" name="title" /><br> 選擇檔案：<input type="file" name="upload" /><br> <input value="上傳" type="submit" /> </form> </body> </html>
上傳成功之後跳轉的頁面succ.jsp：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% 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>1</title> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> -->
</head> <body> <h3>上傳成功！！！</h3> </body> </html>

上傳成功後跳轉到succ.jsp頁面，並且顯示上傳成功：
