最近写了一个Spring.net的架构。
一、架构主图
架构图的数据流程走向是：
UI层=》UILogic》=》Service》Business=》DataAccess
中间使用到的公共类库，如，Aop和Container
二、Default.aspx页面代码
<%@ 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>
举一个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>
<!-- 环绕通知 -->
<object id="UserAdvice" type="ST.Spring.Aop.UserAdvice,ST.Spring.Aop"></object>
<!-- UserBll class -->
<object id="IUserBll" type="Spring.Aop.Framework.ProxyFactoryObject">
<!-- 拦截目标 -->
<property name="target" ref="UserBll" />
<!-- 具体通知 -->
<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，继承了是Spring.Aop.Framework.ProxyFactoryObject的ProxyFactoryObject类，被UserBll引用或者说实现。UserBll继承了ST.Spring.Business.UserBll类。
一句话，ioc就是为了在.cs业务类中，通过接口名创建实现对象。
var userBll = ObjectContainer.CreateObject<IUserBll>();
三、UILogic页面的
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("添加用户:" + (result != null ? "成功" : "失败") + "<br />");
////Response.Write(result.UserName + result.Sex + result.Password + "<br/>");
//Response.Write(user.SendMsg());
Response.End();
}
}
}
四、IService.cs和Service.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ST.Spring.DataModel;
namespace ST.Spring.IService
{
public interface IUserService
{
/// <summary>
/// 添加用户
/// </summary>
/// <param name="u"></param>
/// <returns></returns>
User AddUser(User u);
/// <summary>
/// 发送消息
/// </summary>
/// <returns></returns>
string SendMsg();
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ST.Spring.Container;
using ST.Spring.DataModel;
using ST.Spring.IBusiness;
using ST.Spring.IService;
namespace ST.Spring.Service
{
/// <summary>
/// 用户service
/// </summary>
public class UserService : IUserService
{
private IUserBll UserBll { get; set; }
private string _msg;
private string _constructor;
//构造函数注入
public UserService(string constructor)
{
this._constructor = constructor;
}
//通过属性注入 相当于替代了 IUser _user = new UserDAO把这个过程交给容器来处理
/// <summary>
/// 消息内容通过属性注入
/// </summary>
public string MsgInfo
{
get { return this._msg; }
set { this._msg = value; }
}
/// <summary>
/// 添加用户
/// </summary>
/// <param name="u"></param>
/// <returns></returns>
public User AddUser(User u)
{
var userBll = ObjectContainer.CreateObject<IUserBll>();
return userBll.AddUser(u);
}
/// <summary>
/// 发送消息
/// </summary>
/// <returns></returns>
public string SendMsg()
{
return "注入的MsgInfo值是：" + MsgInfo + "<br/>" + "_constructor通过构造函数注入的值：" + _constructor;
}
}
}
五、Aop类UserAdvice.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using AopAlliance.Intercept;
namespace ST.Spring.Aop
{
/// <summary>
/// 环绕通知
/// </summary>
public class UserAdvice : IMethodInterceptor
{
#region IMethodInterceptor 成员
public object Invoke(IMethodInvocation invocation)
{
string methodName = invocation.Method.Name;
//可以拦截方法进行日志、权限等操作
if (methodName == "AddUser")
{
//throw new Exception(invocation.Method.Name);
}
object returnValue = invocation.Proceed();
//return "被拦截的方法:" + methodName + "<br/>" + "返回的值:" + returnValue.ToString();
return returnValue;
}
#endregion
}
}
六、IOC容器创建类ObjectContainer.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Spring.Context;
using Spring.Context.Support;
namespace ST.Spring.Container
{
public static class ObjectContainer
{
//使用自定义的配置文件---获取容器
private static IApplicationContext Ctx { get; set; }
public static TObject CreateObject<TObject>()
{
Ctx = new XmlApplicationContext(string.Format("~/SpringConfig/{0}.xml", typeof(TObject).Assembly.GetName().Name));
var str = string.Empty;
var t = typeof(TObject).FullName;
if (t.LastIndexOf('.') > 0)
{
str = t.Substring(t.LastIndexOf('.') + 1, t.Length - t.LastIndexOf('.') - 1);
}
return (TObject)Ctx.GetObject(str);
}
}
}
创建方法如下：
var userService = *OBJECTCONTAINER.CREATEOBJECT<IUSERSERVICE>();*
User result = userService.AddUser(new User() { UserName = "xqh", Sex = "男", Password = "123" });
