在struts中通过一个bean的数组把页面的参数传递到action中去

1.jsp页面

<%@ 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>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="user.action" method="post" >
    	用户名：<input type="text" name="list[0]" id="uname"/></br>
    	密码：<input type="text" name="list[1]" id="pwd"/></br>
    	<input type="submit" value="提交"/>
    </form>
  </body>
</html>

2.javabean类

package com.bean;

public class testbean {
	private String uname;
	private String pwd;
	public String getUname() {
		return uname;
	}
	public void setUname(String uname) {
		this.uname = uname;
	}
	public String getPwd() {
		return pwd;
	}
	public void setPwd(String pwd) {
		this.pwd = pwd;
	}
	
	

}

3.action类

package com.action;

import java.util.List;

import com.bean.testbean;
import com.opensymphony.xwork2.ActionSupport;

public class testaction extends ActionSupport{

	
	private List<String> list;
	
	public List<String> getList() {
		return list;
	}
	public void setList(List<String> list) {
		this.list = list;
	}
	
	public String dis(){
		for(int i=0;i<list.size();i++){
			System.out.println("========="+list.get(i));
		}
		
		return "show";
		
	}
}

4.struts.xml文件的配置

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
	<package name="default" extends="struts-default" namespace="/">
		<!--  <action name="user" class="com.action.testaction">
			<result name="ok">/index.jsp</result>
		</action>-->
		<action name="user" class="com.action.testaction" method="dis">
			<result name="show">/index.jsp</result>
		</action>
	</package>
</struts>
