Why I can not use jsp:include to pass a parameter in Spring MVC?

Question

In my Spring MVC project,In my page,I want to load the other page.So I use jsp:include .But I find the I always get the null parameter value in the other page.I try to create a single Servlet project,And I can get the value well. What's wrong with my code?

This is my first page:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8" %> 
<html xmlns="http://www.w3.org/1999/xhtml">
<head> 
<title></title> 
<jsp:include page="../common/common.jsp" flush="true">
  <jsp:param name="gisType" value="baidu" />
 </jsp:include> 
</head> 
<body>

This is the other page:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<% 
 String gisType = "baidu";
  gisType = request.getParameter("gisType");
  System.out.print(gisType);
 %>
  <script type="text/javascript"> 
 var map;
 var gisType = "<%=gisType%>"; 
 alert(gisType);
 </script>

My mvc config file is like this:

    <beans xmlns="http://www.springframework.org/schema/beans"

Try to use ${} expression to get the param,

<script type="text/javascript"> 
  var map;
  var gisType = "${param.gisType}"; 
  alert(gisType);
</script>
