Java 中遍历 Session or Request

1.Java 中遍历 Session 

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

2.Java 中遍历 Request

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();   
    System.out.println("\nkey="+strKey);  
    String[] value=(String[])element.getValue();  
    if(value.length>0){  
     for(int i=0;i<value.length;i++)  
	System.out.println("\nvalue"+String.valueOf(i)+"="+value[i].toString());  
      }  
    int a=1;  
}
