这里取值后并放入了map

Map<String, String> map = new HashMap<String, String>();
        Enumeration enu=request.getParameterNames();
        while(enu.hasMoreElements()){
        String paraName=(String)enu.nextElement();
        System.out.println(paraName+": "+request.getParameter(paraName));
        map.put(paraName, request.getParameter(paraName));
        }
