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

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; }

        }
    }

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

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>
