Spring.NET IoC容器的用法。

通过简单的例子学习Spring.Net

1、先创建一个控制台程序项目。

2、添加IUserInfoDal 接口。

namespace Spring.Net
{
    public interface IUserInfoDal
    {
        void Show();
    }
}

3、添加AdoNetUserInfoDal类和EFUserInfoDal类，继承IUserInfoDal接口。

AdoNetUserInfoDal.cs

public class AdoNetUserInfoDal:IUserInfoDal
    {
        public void Show()
        {
            Console.WriteLine("我是 AdoNet Dal );
        }
    }

EFUserInfoDal.cs

public class EFUserInfoDal: IUserInfoDal
    {
        public void Show()
        {
            Console.WriteLine("我是EF Dal);
        }     
    }

4、引用Spring.Net程序集 Spring.Core.dll 和 Common.Logging.dll

5、添加Spring.Net配置节点，配置object节点

  
  
    
    
      

      

    
  
  
     
        
    

  
  
    
      
      
    
    
      
      An  example that demonstrates simple IoC features.
      
            
  

6、开始写主函数，创建spring容器上下文
namespace Spring.Net
{
    class Program
    {
        static void Main(string[] args)
        {
            //控制权没有反转
            //IUserInfoDal infoDal = new EFUserInfoDal();


            //Spring.Net 创建实例的方式转为容器帮我们创建
            //创建spring容器上下文
            IApplicationContext ctx = ContextRegistry.GetContext();
            //通过容器创建对象
            IUserInfoDal efDal = ctx.GetObject("UserInfoDal") as IUserInfoDal;
            efDal.Show();
            Console.ReadKey();
        }
    }
}

7、属性注入

8、构造函数注入

<object name="UserInfoDal2" type="Spring.Net.AdoNetUserInfoDal, Spring.Net">
   <constructor-arg index="0" value="张三"/>
   <constructor-arg index="1" ref="UserInfo"/>
object>

9、容器配置

<context>
   
   <resource uri="config://spring/objects"/>
   
   
   
   
context>

10、完整例子

IUserInfoDal.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Spring.Net
{
    public interface IUserInfoDal
    {
        UserInfo UserInfo { get; set; }
        string Name { get; set; }

        void Show();
    }
}

AdoNetUserInfoDal.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Spring.Net
{
    public class AdoNetUserInfoDal:IUserInfoDal
    {
        public AdoNetUserInfoDal(string name, UserInfo userInfo)
        {
            Name = name;
            UserInfo = userInfo;
        }
        public UserInfo UserInfo { get; set; }
        public string Name { get; set; }

        public void Show()
        {
            Console.WriteLine("我是 AdoNet Dal ,属性注入：Name=" + Name);
            Console.WriteLine("UserInfo ,Name=" + UserInfo.Name + " Age=" + UserInfo.Age);
        }
    }
}

EFUserInfoDal.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Spring.Net
{
    public class EFUserInfoDal: IUserInfoDal
    {
        public EFUserInfoDal()
        {

        }
        public UserInfo UserInfo { get; set; }
        public string Name { get; set; }

        public void Show()
        {
            Console.WriteLine("我是EF Dal,属性注入：Name=" + Name);
            Console.WriteLine("UserInfo ,Name=" + UserInfo.Name + " Age=" + UserInfo.Age);
        }     
    }
}

App.config

Program.cs

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

//Spring.Aop.dll 面向切面编程
//Spring.Core.dll spring框架基础
//Common.Logging.dll 这个必须也要引用

namespace Spring.Net
{
    class Program
    {
        static void Main(string[] args)
        {
            //控制权没有反转
            //IUserInfoDal infoDal = new EFUserInfoDal();

            //Spring.Net 创建实例的方式转为容器帮我们创建
            //第一步，引用Spring.Net程序集 Spring.Core.dll 和 Common.Logging.dll
            //第二步，添加Spring.Net配置节点
            //第三步，配置object节点
            //第四步，创建spring容器上下文
            IApplicationContext ctx = ContextRegistry.GetContext();
            //第五步，通过容器创建对象
            IUserInfoDal efDal = ctx.GetObject("UserInfoDal") as IUserInfoDal;
            efDal.Show();

            IUserInfoDal adoDal = ctx.GetObject("UserInfoDal2") as IUserInfoDal;
            adoDal.Show();

            Console.ReadKey();
        }
    }
}

 

下面是MVC项目中使用Spring.Net融合的例子

1、将Spring.net程序集复制到项目下的packages文件夹中。

2、项目中添加引用Spring.Core.dll、Common.Logging.dll、Spring.Web.Mvc4.dll、Spring.Web.dll

3、修改Web.config,配置节点

<configuration>
  <configSections>
    
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    
    
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.MvcContextHandler, Spring.Web.Mvc4"/>
    sectionGroup>
  configSections>
  
  <spring>
    <context>
      <resource uri="file://~/Config/controllers.xml"/>
    context>
  spring>

configuration>

4、项目中创建Config文件夹，controllers.xml文件。

xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">

  <object type="HX.Shop.UI.Main.Controllers.AdminController, HX.Shop.UI.Main" singleton="false" >
    <property name="AdminService" ref="AdminService" />
  object>
  <object name="AdminService" type="HX.Shop.BLL.AdminService, HX.Shop.BLL" singleton="false" >
    
  object>
objects>

 

5、Global.asax 中修改 SpringMvcApplication

public class MvcApplication : Spring.Web.Mvc.SpringMvcApplication //System.Web.HttpApplication
