Struts list里Map嵌套Map

import java.util.Map;
import java.util.List;
import java.util.HashMap;
import java.util.ArrayList;

public class ToAddContentTypeAction
extends ContentTypeAction
{
//定义JSP页面使用的List及Map;结构如下；
private List<Long> list = new ArrayList<Long>();
private Map<Long, Map<String, Integer>> map=new HashMap<Long, Map<String, Integer>>();

public String execute()
throws Exception
{
ContentTypeManager contentTypeManager = BeanLookup.getInstance().lookup(
ContentTypeManager.class);
contentTypes = contentTypeManager.getAllContentTypes();
list.add(((Integer)1).longValue());
list.add(((Integer)2).longValue());
Map<String,Integer> temp1 = new HashMap<String, Integer>();
temp1.put("temp1.1",3) ;
temp1.put("temp1.2",4) ;
Map<String,Integer> temp2 = new HashMap<String, Integer>();
temp2.put("temp2.1",5) ;
temp2.put("temp2.2",6) ;
map.put(list.get(0), temp1);
map.put(list.get(1), temp2);
return SUCCESS;
}


public List<Long> getList()
{
return list;
}

public void setList(List<Long> list)
{
this.list = list;
}

public Map getMap()
{
return map;
}

public void setMap(Map map)
{
this.map = map;
}
}
2、JSP页面的定义如下：

<s:iterator value="list">
<s:select list="map.get(longValue()).entrySet()" listKey="getKey()" listValue="getValue()" name="map1"
emptyOption="true"/>
</s:iterator>
