解决方案 »

  1.   

    jsp页面呢？最好直接用Fromfile这个类，方便一点
      

  2.   

    upload.jsp:
    就这一个页面
    <%@ page contentType="text/html;charset=gbk"%>
    <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
    <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
    <%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
    <%@ taglib uri="http://struts.apache.org/tags-nested" prefix="nested" %>
    <html>
    <head>  
    <title><bean:message key="login.page.title"/></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> 
      
        <form action="upload.do" method="post" enctype="multipart/form-data">
         文件说明：<input type="text" name="re"/><br>
        文件：<input type="file" name="myfile"  /><br>
        <input type="submit" value="保存"/>
    </form> 
      </body>
    </html>
      

  3.   

    private String fileName;
    public void setMyFileFileName(String fileName)  {
             this .fileName = fileName;
        } 你实体类中有没有这样设置 因为
    <input type="file" name="myfile"  /> <br>标志不仅仅是绑定到myFile，还有myFileContentType（上传文件的MIME类型）和myFileFileName（上传文件的文件名，该文件名不包括文件的路径）。因此<input type="file" name="myfile"  />对应Action类里面的xxx、xxxContentType和xxxFileName三个属性。
