语言和Struts2.0迭代标签,处理Map里嵌套Map的处理方法
1、Action的结构如下：

package?com.ceno.mcps.cms.web.actions.contenttype;

import?com.ceno.mcps.cms.ContentTypeManager;
import?com.ceno.mcps.cms.model.ContentType;
import?com.ceno.ejb.lookup.BeanLookup;

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?list?=?new?ArrayList();
private?Map>?map=new?HashMap>();

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?temp1?=?new?HashMap();
temp1.put(“temp1.1″,3)?;
temp1.put(“temp1.2″,4)?;
Map?temp2?=?new?HashMap();
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?getList()
{
return?list;
}

public?void?setList(List?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：

emptyOption="true"/>
