Spring.Net

简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。

1.创建一个空MVC项目，命名为Spring.Net.Demo

2.右键项目中的引用，选择“管理NuGet工具包”,输入“Spring.Net”，如下图

3.添加IUserInfo接口：

public interface IUserInfo
    {
        string ShowMeg();
    }

4.添加Order类和UserInfo类，UserInfo类继承IUserInfo接口

 public interface IUserInfo
    {
        string ShowMeg();
    }

 public class UserInfo : IUserInfo
    {
        public string UserName { get; set; }

        public Order Order { get; set; }

        public string ShowMeg()
        {
            return UserName + "的订单号是：" + Order.OrderNo;
        }
    }

 public class Order
    {
        public string OrderNo { get; set; }
    }

5.在Web.config中添加Spring.Net配置信息

 <configSections>
    <!--跟下面Spring.Net节点配置是一一对应关系-->
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <!--Spring.Net节点配置-->
  <spring>
    <!--容器配置-->
    <context>
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net">
      <!--name 必须要唯一的，type=类的全名称，所在的程序集-->
      <object name="UserInfo" type="Spring.Net.Demo.UserInfo,Spring.Net.Demo">
        <property name="UserName" value="神刀张三"/>
        <!--ref指向下面的属性注入-->
        <property name="Order" ref="Order"/>
      </object>
      <!--复杂属性注入-->
      <object name="Order"  type="Spring.Net.Demo.Order, Spring.Net.Demo">
        <property name="OrderNO" value="201606122226"/>
      </object>
    </objects>
  </spring>

6.添加Home控制器和Index视图

HomeController:

using Spring.Context;
using Spring.Context.Support;
using System.Web.Mvc;

namespace Spring.Net.Demo.Controllers
{
    public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            IApplicationContext context = ContextRegistry.GetContext();
            IUserInfo userInfo = (IUserInfo)context.GetObject("UserInfo");
            ViewBag.Msg = userInfo.ShowMeg();
            return View();
        }
    }
}

Index:

@{
    ViewBag.Title = "Index";
}

<h2>@ViewBag.Msg</h2>
