这样就不会局限在转换到List<Map<String,Object>>这一种类型上了.
    
    可以转换成List<Map<String,V>>上等,进行泛型转换
    
    虽然多了一个参数,但是可以重载啊
    
    注: 感觉field.get(key) 这里处理的不是很好,如果有更好的办法可以留言

public static <K, V> List<Map<K, V>> castListMap(Object obj, Class<K> kCalzz, Class<V> vCalzz) {
    		List<Map<K, V>> result = new ArrayList<>();
    		if (obj instanceof List<?>) {
    			for (Object mapObj : (List<?>) obj) {
    				if (mapObj instanceof Map<?, ?>) {
    					Map<K, V> map = new HashMap<>(16);
    					for (Map.Entry<?, ?> entry : ((Map<?, ?>) mapObj).entrySet()) {
    						map.put(kCalzz.cast(entry.getKey()), vCalzz.cast(entry.getValue()));
    					}
    					result.add(map);
    				}
    			}
    			return result;
    		}
    		return null;
    }
