Java使用entrySet方法获取Map集合中的元素

        ReMap parmMap = new ReMap();
            Map<String, String[]> uriAttributes = request.getParameterMap();
            for (Map.Entry<String, String[]> attr : uriAttributes.entrySet()) {
                String attrkey = attr.getKey().toString();
                for (String attrVal : attr.getValue()) {
                    parmMap.put(attrkey, attrVal);
                }
            }
