小弟最近改造用户登陆模块，因为涉及到集群的部署，所以session中的对象都要是可序列化的，然后其中有一段特别不解，而且一直报错：代码如下：

List menuList = (List) JSONArray.toList(JSONArray.fromObject(menuJson),HashMap.class)

其中menuJson为json字符串，单元测试代码：如下

    ObjectOutputStream objectOutputStream2 = new ObjectOutputStream(
                new FileOutputStream(new File("D:\\testFile1.txt")));
        objectOutputStream2.writeObject(menuList);
        objectOutputStream2.flush();
        objectOutputStream2.close();
        ObjectInputStream objectInputStream2 = new ObjectInputStream(
                new FileInputStream(new File("D:\\testFile1.txt")));
        List sn2 = (List) objectInputStream2.readObject();

        objectOutputStream2.close();
        System.out.println("sn2------------------------------------"+sn2.size());

报错如下：

java.io.NotSerializableException: net.sf.json.JSONObject
