Java 中遍历 Session or Request

session的遍历：

java.util.Enumeration   e   =   request.getSession().getAttributeNames(); while( e.hasMoreElements())   {     String sessionName=(String)e.nextElement();     out.println("\nsession item name="+sessionName);    out.println("\nsession item value="+request.getSession().getAttribute(sessionName));} 

request的遍历：

Map map = new HashMap();map = request.getParameterMap();for(Iterator iter = map.entrySet().iterator();iter.hasNext();){      Map.Entry element = (Map.Entry)iter.next();      String strKey = element.getKey().toString();     out.println("\nkey="+strKey);    String[] value=(String[])element.getValue();    if(value.length>0){ for(int i=0;i<value.length;i++)out.println("\nvalue"+String.valueOf(i)+"="+value[i].toString());  }    int a=1;}
