最近公司用到了Unity，自己就研究了一下。
新建一个ASP.NET MVC基本项目，在NuGet上引入Unity4.0.1最新版。
因为我使用的项目为ASP.NET MVC，所以又添加一个Unity bootstrapper for ASP.NET MVC。
NuGet会帮你在App_Start文件夹下自动添加两个文件UnityConfig.cs和UnityMvcActivator.cs。
文件UnityConfig.cs是配置Unity依赖注入用的，可以分为两种
这两种方式的不同点在于，修改依赖注入时，如果是方式一可以在系统运行时修改（支持热插拔）。
文件UnityWebActivator.cs是我们创建的依赖关系注册到MVC中。
我们需要做的是在Global.asax文件中将Unity运行。
下面来详细讲述一下这两方式的配置：
方式一使用web.config配置：
1.在UnityConfig.cs下将注释取消container.LoadConfiguration()
/// <summary>Registers the type mappings with the Unity container.</summary>
/// <param name="container">The unity container to configure.</param>
/// <remarks>There is no need to register concrete types such as controllers or API controllers (unless you want to
/// change the defaults), as Unity allows resolving a concrete type even if it was not previously registered.</remarks>
public static void RegisterTypes(IUnityContainer container)
{
// NOTE: To load from web.config uncomment the line below. Make sure to add a Microsoft.Practices.Unity.Configuration to the using statements.
container.LoadConfiguration(); // TODO: Register your types here
// container.RegisterType<IProductRepository, ProductRepository>();
}
2.在configSections节点下添加以下内容
<configSections>
<section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Microsoft.Practices.Unity.Configuration"/>
</configSections>
3.配置unity节点信息
<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<assembly name="IBLL"/>
<assembly name="BLL"/>
<containers>
<container>
<register type="IBLL.ITest,IBLL" mapTo="BLL.Test,BLL" />
</container>
</containers>
</unity>
配置完成运行就ok了。
这是我遇到一个问题，找了很多资料才解决的
原来web.config是这样配置的
<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<containers>
<container>
<register type="IBLL.ITest" mapTo="BLL.Test" />
</container>
</containers>
</unity>
这种情况下会报这种错误
The type name or alias IBLL.ITest could not be resolved. Please check your configuration file and verify this type name.
方式二使用代码配置：
这种方式十分的简单基本上我们只要参考作者给的提示就ok
在UnityConfig.cs下配置如下代码：
/// <summary>Registers the type mappings with the Unity container.</summary>
/// <param name="container">The unity container to configure.</param>
/// <remarks>There is no need to register concrete types such as controllers or API controllers (unless you want to
/// change the defaults), as Unity allows resolving a concrete type even if it was not previously registered.</remarks>
public static void RegisterTypes(IUnityContainer container)
{
// NOTE: To load from web.config uncomment the line below. Make sure to add a Microsoft.Practices.Unity.Configuration to the using statements.
//container.LoadConfiguration(); // TODO: Register your types here
// container.RegisterType<IProductRepository, ProductRepository>();
container.RegisterType<IBLL.ITest,BLL.Test>();
}
以上是个人使用经验分享给大家，上面的内容比较浅显，如果有错误请大家指正
