        Morphia morphia = new Morphia();

        // 创建Datastore对象
        Datastore datastore = morphia.createDatastore(new MongoClient(), "your_database_name");

        // 反序列化字符串为日期
        String dateString = "2022-01-01";
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        Date date = dateFormat.parse(dateString);

        // 创建User对象并设置日期字段
        User user = new User();
        user.setBirthDate(date);

        // 将User对象保存到数据库
        datastore.save(user);
    }
