如要实现多图片上传，只要改两地方就行了。

1.jsp页面

<%@ page language="java" contentType="text/html; charset=GBK"%>
<%@taglib prefix="s" uri="/struts-tags" %>
<html>
	<head>
		<title>Struts 2 File Upload</title>
	</head>
	<body topmargin="2">
		<FORM action="/brand/test" method="post"
			ENCTYPE="multipart/form-data">
			<input type="hidden" name="username" value="username_value"/>
			<input type="hidden" name="password" value="password_value"/>
			<s:file name ="myFile" />
			<s:file name ="myFile1" />  
			<INPUT type="submit" value="上传">
		</FORM>
		<s:fielderror/> 
	</body>
</html>

2.action

private static final long serialVersionUID = 0x85369b8626L;
    private static final int BUFFER_SIZE = 16384;
    private File myFile;
    private File myFile1;
    private String fileName;
    private String fileName1;
    public void setMyFileFileName(String fileName)
    {
        this.fileName = fileName;
    }

    public void setMyFile(File myFile)
    {
        this.myFile = myFile;
    }
    public void setMyFile1FileName(String fileName)
    {
    	this.fileName1 = fileName;
    }
    public void setMyFile1(File myFile1)
    {
    	this.myFile1 = myFile1;
    }

这样就可以获取到值了！
