<a name="h3_1_2"></a><h3>示例二</h3>
　　本示例为2017.12.08补充。
　　创建一个mvc5项目 Web.Mvc，然后在创建一个Business类库，将类库添加引用到Web.Mvc项目，在Web.Mvc项目通过nuget添加unity.mvc5 （1.3.0）
　　命令：Install-Package Unity.Mvc5 -Version 1.3.0
　　安装后如图

　　1. 调用注册组件
　　在Global.asax.cs 的Application_Start 方法添加 UnityConfig.RegisterComponents() ，MVC会使用 Unity.Mvc5的 DependencyResolver去解析服务
<div class="cnblogs_code"><div class="cnblogs_code_toolbar"><a href="javascript:void(0);" onclick="copyCnblogsCode(this)" title="复制代码"><img src="//common.cnblogs.com/images/copycode.gif" alt="复制代码"></a></div>

{
AreaRegistration.RegisterAllAreas();
UnityConfig.RegisterComponents();//在此处添加
 FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);

}</pre>
<div class="cnblogs_code_toolbar"><a href="javascript:void(0);" onclick="copyCnblogsCode(this)" title="复制代码"><img src="//common.cnblogs.com/images/copycode.gif" alt="复制代码"></a></div></div>
　　2.注册服务
　　找到App_Start下的UnityConfig类，如下修改
<div class="cnblogs_code"><div class="cnblogs_code_toolbar"><a href="javascript:void(0);" onclick="copyCnblogsCode(this)" title="复制代码"><img src="//common.cnblogs.com/images/copycode.gif" alt="复制代码"></a></div>
<pre> public static class UnityConfig
{
public static void RegisterComponents()
{
var container = new UnityContainer();

//在这里使用container注册所有服务
container.RegisterType<IUserService, UserService>();//自定义的服务

DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}

<div class="cnblogs_code_toolbar"><a href="javascript:void(0);" onclick="copyCnblogsCode(this)" title="复制代码"><img src="//common.cnblogs.com/images/copycode.gif" alt="复制代码"></a></div></div>
　　3.修改控制器Home和页面Index

IOC:英文全称：Inversion of Control，中文名称：控制反转，它还有个名字叫依赖注入（Dependency Injection）。 　　作用：将各层的对象以松耦合的方式组织在一起，解耦，各层对象的调用完全面向接口。当系统重构的时候，代码的改写量将大大减少。 　　依赖注入： 当一个类的实例需要另一个类的实例协助时，在传统的程序设计过程中，通常有调用者来创建被调用者的实例。然而采用依赖注入的方式，创建被调用者的工作不再由调用者来完成，因此叫控制反转，创建被调用者的实例的工作由IOC容器来完成，然后注入调用者，因此也称为依赖注入。

Unity是微软Patterns & Practices团队所开发的一个轻量级的，并且可扩展的依赖注入(Dependency Injection)容器；

它支持常用的三种依赖注入方式：构造器注入(Constructor Injection)、属性注入(Property Injection)，以及方法调用注入(Method Call Injection)。

现在Unity最新的版本的4.0版，可以在微软的开源站点 https://github.com/unitycontainer/unity 下载最新的发布版本。

通过使用Unity，我们能轻松构建松耦合结构的程序，从而让整个程序框架变得清晰和易于维护。

创建一个mvc5项目 Web.Mvc，然后在创建一个Business类库，将类库添加引用到Web.Mvc项目.

<a name="h3_1_0"></a><h3>Business类库</h3>

类库代码

a、Business类库定义一个接口IUserService

<pre>namespace Business

{

/// <summary>

/// 显示信息

/// </summary>

public interface IUserService

{

string Display(string mes);

}

}</pre>

b、Business类库实现接口

<pre>namespace Business

{

public class UserService : IUserService

{

/// <summary>

/// 显示信息

/// </summary>

/// <param name="mes"></param>

public string Display(string mes)

{

return "I say：" + mes;

}

}</pre>

在Web.Mvc项目通过nuget添加unity.mvc5 （1.2.3）

1.注册服务

注册依赖使用依赖注入生效，在Web.Mvc项目的Global.asax进行注册

<pre>using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using System.Web.Optimization;

using System.Web.Routing;

using Business;

using Microsoft.Practices.Unity;

using Unity.Mvc5;

namespace Web.Mvc

{

public class MvcApplication : System.Web.HttpApplication

{

protected void Application_Start()

{

AreaRegistration.RegisterAllAreas();

FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

RouteConfig.RegisterRoutes(RouteTable.Routes);

BundleConfig.RegisterBundles(BundleTable.Bundles);

//注入 Ioc

var container = this.BuildUnityContainer();

DependencyResolver.SetResolver(new UnityDependencyResolver(container));

}

IUnityContainer BuildUnityContainer()

{

var container = new UnityContainer();

container.RegisterType<IUserService, UserService>();

return container;

}

}</pre>

2.注入服务

<pre>namespace Web.Mvc.Controllers

{

public class HomeController : Controller

{

private IUserService userService;

public HomeController(IUserService userService)

{

this.userService = userService;

}

public ActionResult Index()

{

ViewBag.Msg = userService.Display("hahaha");

return View();

}

}</pre>

e、在Index.cshtml找个地方写入@ViewBag.Msg 就可以，如

<pre><h1>ASP.NET - @ViewBag.Msg</h1></pre>

</div>

最后运行项目，实现效果

<h4>ASP.NET - I say：hahaha</h4>

本示例为2017.12.08补充。

创建一个mvc5项目 Web.Mvc，然后在创建一个Business类库，将类库添加引用到Web.Mvc项目，在Web.Mvc项目通过nuget添加unity.mvc5 （1.3.0）

命令：Install-Package Unity.Mvc5 -Version 1.3.0

安装后如图

1. 调用注册组件

在Global.asax.cs 的Application_Start 方法添加 UnityConfig.RegisterComponents() ，MVC会使用 Unity.Mvc5的 DependencyResolver去解析服务

<pre>protected void Application_Start()

{

AreaRegistration.RegisterAllAreas();

UnityConfig.RegisterComponents();//在此处添加

FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

RouteConfig.RegisterRoutes(RouteTable.Routes);

BundleConfig.RegisterBundles(BundleTable.Bundles);

}</pre>

2.注册服务

找到App_Start下的UnityConfig类，如下修改

<pre> public static class UnityConfig

{

public static void RegisterComponents()

{

var container = new UnityContainer();

//在这里使用container注册所有服务

container.RegisterType<IUserService, UserService>();//自定义的服务

DependencyResolver.SetResolver(new UnityDependencyResolver(container));

}

}</pre>

3.修改控制器Home和页面Index

<pre>public class HomeController : Controller

{

private IUserService userService;

public HomeController(IUserService userService)

{

this.userService = userService;

}

public ActionResult Index()

{

ViewBag.Name = userService.Display("我是 UNITY 1.3.0");

return View();

}</pre>

页面代码

<h1>Unity 入门</h1>

class="lead">@ViewBag.Name

</div>

</pre>

</div>

效果

对示例一的注册进行独立封装到BootStrapper中

c、注册依赖使用依赖注入生效

在Web.Mvc项目的Global.asax进行注册

<pre>using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using System.Web.Optimization;

using System.Web.Routing;

using Business;

using Microsoft.Practices.Unity;

using Unity.Mvc5;

namespace Web.Mvc

{

public class MvcApplication : System.Web.HttpApplication

{

protected void Application_Start()

{

AreaRegistration.RegisterAllAreas();

FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

RouteConfig.RegisterRoutes(RouteTable.Routes);

BundleConfig.RegisterBundles(BundleTable.Bundles);

//注入 Ioc

BootStrapper.Initialise();

}

}</pre>

BootStrapper代码

<pre>using System;

using System.Collections.Generic;

using System.Configuration;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using Business;

using Microsoft.Practices.Unity;

using Microsoft.Practices.Unity.Configuration;

using Unity.Mvc5;

namespace Web.Mvc

{

public class BootStrapper

{

/// <summary>

/// 获取容器-注册依赖关系

/// </summary>

/// <returns></returns>

public static IUnityContainer Initialise()

{

var container = BulidUnityContainer();

DependencyResolver.SetResolver(new UnityDependencyResolver(container));

return container;

}

/// <summary>

/// 加载容器

/// </summary>

/// <returns></returns>

private static IUnityContainer BulidUnityContainer()

{

var container = new UnityContainer();

RegisterTypes(container);

return container;

}

/// <summary>

/// 实施依赖注入

/// </summary>

/// <param name="container"></param>

private static void RegisterTypes(IUnityContainer container)

{

//类型的配置容器注册

container.RegisterType<IUserService, UserService>();

//container.RegisterType<IUserService, UserService>(new ContainerControlledLifetimeManager());//通过生命周期实现了单例模式

//已有对象实例的配置容器注册,也为单例

//UserService userService = new UserService();

//container.RegisterInstance<IUserService>(userService);

}

}</pre>

<a name="h3_2_0"></a><h3 id="xishuai_h7">Unity注册配置</h3>

修改上面的方法，将注册放到配置文件中

1.方法修改

/// 实施依赖注入

/// </summary>

/// <param name="container"></param>

{

////依赖关系可以选择代码形式，也可以用配置文件的形式

UnityConfigurationSection config = (UnityConfigurationSection)ConfigurationManager.GetSection(UnityConfigurationSection.SectionName);

config.Configure(container, "defaultContainer");

}</pre>

<pre>UnityConfigurationSection.SectionName为unity</pre>

2.配置文件

提示：自定义web.config节点来实现

</configSections>

</register>

</container>

</containers>

</unity>

</configuration></pre>

或者为

直接指定命名空间

</register>

</container>

</containers>

</unity></pre>

或者为

指定程序集名称

</register>

</container>

</containers>

</unity></pre>
