一、action的写法

package action.mapAction;

import java.util.Map;

public class MapAction {
private Map<String, String> map;

public String test() {
  System.out.println(map.size());
  return "success";
}

public Map<String, String> getMap() {
  return map;
}

public void setMap(Map<String, String> map) {
  this.map = map;
}
}

二 jsp文件

2.1 传值页面 index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
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">
</head>

<body>
  <form action="map!test">
   <input type="text" name="map['name']">
   <input type="text" name="map['password']">
   <input type="submit">
  </form>
</body>
</html>

2.1 接受值页面 success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
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 'success.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">
</head>

<body>
  <s:iterator value="map" var="ha">
   <s:property value="#ha.key" />:<s:property value="#ha.value" /><br/>
  </s:iterator>
</body>
</html>
