上传功能的实现（Struts2）

在WebRoot根目录新建一个images文件夹

upload.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<html>
  <head>
    <base href="<%=basePath%>">
  </head>
  
  <body bgcolor="green"> 
      <s:form name="" action="momo/upload" enctype="multipart/form-data">
          图片路径：<s:file name="myFile" label="浏览照片"/>
              <s:submit value="上传"/>
      </s:form>
      
  </body>
</html>

firefox 和 ie 的文件类型区别

Firefox：
image/jpeg, image/bmp, image/gif, image/png

ie 6：
image/pjpeg ,image/bmp, image/gif, image/x-png

ie 7：
image/pjpeg, image/bmp, image/gif, image/x-png

ie 8：
image/pjpeg, image/bmp, image/gif, image/x-png

Ie 9：
image/jpeg, image/bmp, image/gif, image/png

所以在struts.xml配置文件中需要

<param name="allowedTypes">
image/bmp,image/png,image/gif,image/jpeg,image/jpg,
image/pjpeg ,image/bmp, image/gif, image/x-png,
</param>
