[quote]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 + "/";
%>
