1.用request.getParameterMap()獲取url中的所有引數

Map map=request.getParameterMap();  
	Set keSet=map.entrySet();  
	for(Iterator itr=keSet.iterator();itr.hasNext();){  
	    @SuppressWarnings("rawtypes")
		Map.Entry me=(Map.Entry)itr.next();  
	    Object ok=me.getKey();  
	    Object ov=me.getValue();  
	    String[] value=new String[1];  
	    if(ov instanceof String[]){  
	        value=(String[])ov;  
	    }else{  
	        value[0]=ov.toString();  
	    }
	    	
	    System.out.println(value[0]);
	    	
	}
 

3.Integer.parseInt((String)request.getAttribute("page"))---int
