首先我们还是新建一个新的web project 取名为upload_test
然后在WebRoot中新建两个jsp页面 upload.jsp 和result.jsp
代码分别如下：
upload.jsp
-
<%@ 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>
-
<form action=‘result.jsp‘ name=‘upload‘>
-
username : <input name=‘name‘ type=‘text‘><br>
-
file : <input name=‘file‘ type=‘file‘ >
-
<br>
-
<input type=‘submit‘ value=‘submit‘ name=‘submit‘>
-
</form>
-
-
-
</body>
-
</html>
然后是result.jsp页面：
-
<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
-
<%
-
String path = request.getContextPath();
-
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
-
%>
-
<%@ page import=‘java.io.*‘ %>
-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
-
<html>
-
<head>
-
<base href="<%=basePath%>">
-
-
<title>My JSP ‘result.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>
-
-
-
<%
-
InputStream is = request.getInputStream(); // 新建一个inputstream对象 注意应该在这个页面中导入java.io.*包
-
-
BufferedReader bu = new BufferedReader( new InputStreamReader(is)); // 将输入的内容转换成字符流
-
-
String buffer = null;
-
-
while( (buffer = bu.readLine()) != null ) //如果还有内容 怎继续输出
-
{
-
out.print(buffer+"<br>");
-
}
-
-
%>
-
</body>
-
</html>
这样的基本课可以上传了
点击文件后点击提交 那么跳转到了result.jsp页面 可是没有任何信息输出 这是怎么回事呢
这里要注意的是 在文件上上传的表单中必须要包含两个内容
method=‘post‘ 还有 enctype=‘multipart/form-data‘
加上这两个内容后，再试一次 就成功了struts中文件的上传和下载,布布扣,bubuko.com
