asp.net hessian + android hessdroid

做android开发时你还在为gson,json而人肉序列化与反序列化吗，上传文件时你还在使用UrlConnection或者HttpClient吗？
下面提供了asp.net 服务端与 android 客户端通过hessdroid (hessian 的android版） 通信解决方案，从此你不用再为上面的问题发愁了
中小应用，使用.net 的EF(数据库优先)或linq，那是相当的方便，做个管理页面也只要拖拖控件就好了（不拖都对不起自己尤其是自己从头整到尾的项目）， 当然你需要使用EmitMapper一类的东西将dto映射到EF实体类上。

服务端定义实体类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

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

        public int Code
        {
            get { return code; }
            set { code = value; }
        }
        public string Msg
        {
            get { return msg; }
            set { msg = value; }
        }
        public T Model
        {
            get { return model; }
            set { model = value; }

        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using cn.fstudio.hessian.dto;

namespace aa.model
{

    public class UserListResponse:ResponseBase<List<UserInfo>>
    {
        private DateTime? addTime;

        public DateTime? AddTime
        {
            get { return addTime; }
            set { addTime = value; }
        }
        private byte[] fileDate;

        public byte[] FileDate
        {
            get { return fileDate; }
            set { fileDate = value; }
        }
        private bool? isAdmin;

        public bool? IsAdmin
        {
            get { return isAdmin; }
            set { isAdmin = value; }
        }

    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace aa.model
{
    public class UserInfo
    {
        private string userNo ;
        public String UserNo
        {
            get
            {
                return userNo;
            }
            set
            {
                userNo = value;
            }
        }
        private string username;

        public string Username
        {
            get { return username; }
            set { username = value; }
        }
        private string password;

        public string Password
        {
            get { return password; }
            set { password = value; }
        }
        private string mobile;

        public string Mobile
        {
            get { return mobile; }
            set { mobile = value; }
        }
        private string userType;

        public string UserType
        {
            get { return userType; }
            set { userType = value; }
        }
        private int recId;

        public int RecId
        {
            get { return recId; }
            set { recId = value; }
        }
        private int userLevel;

        public int UserLevel
        {
            get { return userLevel; }
            set { userLevel = value; }
        }

    }
}

实体类定义不要写成public String Field{get;set;} //因为只动生成的字段名称可能是FieldName_<>K,hessian反射时会出错

服务端接口定义与实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using aa.model;
namespace aa.service
{
    public interface UserService
    {
        UserListResponse getUserlist(UserListResponse res);
        string hello(string name);
         List<UserInfo> getUsers();
         AInfo getAInfo();
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using aa.service;
using aa.model;
using hessiancsharp.server;
namespace AA.ServiceImpl
{
    public class UserServiceImpl:CHessianHandler, UserService
    {
        #region UserService 成员

        public UserListResponse getUserlist(UserListResponse res)
        {
            var response = res;

            UserInfo u = new UserInfo();
            u.Username = "张三";
            u.UserLevel = ;
            response.AddTime = DateTime.Now;

            response.Model.Add(u);

            response.Code = ;
            response.Msg = "终于可以了吗吗吗吗?";

            return response;
        }

        #endregion

        #region UserService 成员

        public string hello(string name)
        {
            return DateTime.Now + "->" + name;
        }
        public List<UserInfo> getUsers()
        {
            UserInfo u = new UserInfo();
            u.Username = "张三";
            u.UserLevel = ;
            return new List<UserInfo>() { u, u, u, u, u, u, u };
        }

        #endregion

        #region UserService 成员

        public AInfo getAInfo()
        {
            return new AInfo() { id = ,name="还是中文" };
        }

        #endregion
    }
}

注意:mvc项目需要在routeConfig中加上 routes.IgnoreRoute("{hessian}.hessian/{*pathInfo}");
web.config中添加
   <httpHandlers>
      <add verb="*" path="UserService.hessian" type="AA.ServiceImpl.UserServiceImpl, AA.ServiceImpl" />
    </httpHandlers>
