Android Gson 操作

JSON序列化后的数据不带类名与名命空间，所以这两个服务端跟客户端可以不对应,需要保证字段对应即可

Asp.net MVC端

using System.Web;

namespace cn.fstudio.hessian.dto
{
    public class ResponseBase<T>
    {
        private int code;

        private T model;

        public int Code
        {
            get { return code; }
            set { code = value; }
