strus2文件上传

来源：互联网发布：创玻璃优化软件编辑：程序博客网时间：2024/06/08 04:08

1. 使用Struts2上传文件到服务器中，文件上传成功后在eclipse的工作区间是看不见上传的文件的，可以在Tomcat服务器指定路径中查看上传的文件信息。

2. WebRoot目录下必须创建一个用于保存上传文件的目录，否则报错“找不到指定目录”。

上传页面：upload.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>Struts2文件上传</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>      <center>       <h1>Struts 2完成上传</h1>         <form action="upload.action" method="post" enctype="multipart/form-data">           <table>               <tr>                   <td>用户名:</td>                   <td><input type="text" name="username" ></td>               </tr>               <tr>                   <td>上传文件:</td>                   <td><input type="file" name="myFile"></td>               </tr>               <tr>                   <td><input type="submit" value="上传"></td>                   <td><input type="reset"></td>               </tr>           </table>         </form>     </center>     </body>   </html>
