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 = 88; response.AddTime = DateTime.Now; response.Model.Add(u); response.Code = 1; 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 = 88; return new List<UserInfo>() { u, u, u, u, u, u, u }; } #endregion #region UserService 成员 public AInfo getAInfo() { return new AInfo() { id = 18,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>
客户端实体类：
