Spring.Net 简单入门学习

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

<?xml version="1.0" encoding="utf-8" ?><configuration>  <!--一定要在紧跟着configuration下面添加-->  <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>      <startup>         <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />    </startup>  <!--Spring.Net节点配置-->  <spring>    <context>      <!--容器配置-->      <resource uri="config://spring/objects"/>    </context>    <objects xmlns="http://www.springframework.net">      <!--这里放容器里面的所有节点-->      <description>An  example that demonstrates simple IoC features.</description>      <!--name 必须要唯一的，type=类的全名称，所在的程序集-->      <object name="UserInfoDal" type="Spring.Net.EFUserInfoDal, Spring.Net">      </object>        </spring></configuration>

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

<!--Spring.Net节点配置-->  <spring>    <context>      <!--容器配置-->      <resource uri="config://spring/objects"/>    </context>    <objects xmlns="http://www.springframework.net">      <!--这里放容器里面的所有节点-->      <description>An  example that demonstrates simple IoC features.</description>      <!--name 必须要唯一的，type=类的全名称，所在的程序集-->      <object name="UserInfoDal" type="Spring.Net.EFUserInfoDal, Spring.Net">        <property name="Name" value="张三"/>        <!--ref指向下面的属性注入-->        <property name="UserInfo" ref="UserInfo"/>      </object>            <!--属性注入-->      <object name="UserInfo" type="Spring.Net.UserInfo, Spring.Net">        <property name="Name" value="李四"/>        <property name="Age" value="15"/>      </object>    </objects>  </spring>

8、构造函数注入

<!--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>   <!--容器配置-->   <resource uri="config://spring/objects"/>   <!--xml文件方式，更改属性，复制到输出目录：始终复制-->   <!--<resource uri="file://objects.xml"/>-->   <!--嵌入程序集方式，assembly://程序集名/项目名/objects.xml，更改属性，始终复制，生成操作，嵌入的资源-->   <!--<resource uri="assembly://Spring.Net/Spring.Net/objects.xml"/>--></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

<?xml version="1.0" encoding="utf-8" ?><configuration>  <!--一定要在紧跟着configuration下面添加-->  <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>      <startup>         <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />    </startup>  <!--Spring.Net节点配置-->  <spring>    <context>      <!--容器配置-->      <resource uri="config://spring/objects"/>      <!--xml文件方式，更改属性，复制到输出目录：始终复制-->      <!--<resource uri="file://objects.xml"/>-->      <!--嵌入程序集方式，assembly://程序集名/项目名/objects.xml，更改属性，始终复制，生成操作，嵌入的资源-->      <!--<resource uri="assembly://Spring.Net/Spring.Net/objects.xml"/>-->    </context>    <objects xmlns="http://www.springframework.net">      <!--这里放容器里面的所有节点-->      <description>An  example that demonstrates simple IoC features.</description>      <!--name 必须要唯一的，type=类的全名称，所在的程序集-->      <object name="UserInfoDal" type="Spring.Net.EFUserInfoDal, Spring.Net">        <property name="Name" value="张三"/>        <!--ref指向下面的属性注入-->        <property name="UserInfo" ref="UserInfo"/>      </object>                  <!--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>      <!--属性注入-->      <object name="UserInfo" type="Spring.Net.UserInfo, Spring.Net">        <property name="Name" value="李四"/>        <property name="Age" value="15"/>      </object>    </objects>  </spring></configuration>

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>    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />        <!-- Spring.Net配置节点 -->    <sectionGroup name="spring">      <section name="context" type="Spring.Context.Support.MvcContextHandler, Spring.Web.Mvc4"/>    </sectionGroup>  </configSections>  <!-- Spring.Net节点详细配置 -->  <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
