最近寫(xiě)了一個(gè)Spring.net的架構(gòu)。
一、架構(gòu)主圖
架構(gòu)圖的數(shù)據(jù)流程走向是：
UI層=》UILogic》=》Service》Business=》DataAccess
中間使用到的公共類庫(kù)，如，Aop和Container
<%@ Page Language="C#" AutoEventWireup="true" Inherits="ST.Spring.UILogic.UserManage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"><title></title></head><body><form id="form1" runat="server"><div </div></form></body></html>舉一個(gè)ioc配置示例：
<?xml version="1.0" encoding="utf-8" ?><objects xmlns="http://www.springframework.net" > <description>An example that demonstrates simple IoC features.</description> <!-- 環(huán)繞通知 --> <object id="UserAdvice" type="ST.Spring.Aop.UserAdvice,ST.Spring.Aop"></object> <!-- UserBll class --> <object id="IUserBll" type="Spring.Aop.Framework.ProxyFactoryObject"><!-- 攔截目標(biāo) --><property name="target" ref="UserBll" /><!-- 具體通知 --><property name="interceptorNames"> <list><value>UserAdvice</value> </list></property> </object> <object id="UserBll" type="ST.Spring.Business.UserBll,ST.Spring.Business"> </object> </objects>IUserBll是接口名，繼承了是Spring.Aop.Framework.ProxyFactoryObject的ProxyFactoryObject類，被UserBll引用或者說(shuō)實(shí)現(xiàn)。UserBll繼承了ST.Spring.Business.UserBll類。
一句話，ioc就是為了在.cs業(yè)務(wù)類中，通過(guò)接口名創(chuàng)建實(shí)現(xiàn)對(duì)象。
var userBll = ObjectContainer.CreateObject<IUserBll>();using System;using System.Collections.Generic;using System.Linq;using System.Text;using ST.Spring.Container;using ST.Spring.DataModel;using ST.Spring.IService;namespace ST.Spring.UILogic{public class UserManage : System.Web.UI.Page{protected void Page_Load(object sender, EventArgs e){var userService = ObjectContainer.CreateObject<IUserService>();User result = userService.AddUser(new User() { UserName = "xqh", Sex = "男", Password = "123" });//Response.Write(user.Singleton() + "<br/>");Response.Write("添加用戶:" + (result != null ?

var userService = *OBJECTCONTAINER.CREATEOBJECT<IUSERSERVICE>();*User result = userService.AddUser(new User() { UserName = "xqh", Sex = "男", Password = "123" });
