ASP.NET MVC 3 & Unity.MVC3(6)

  <unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
    <alias alias="IRepository" type="GenericRepository.IRepository`1, GenericRepository" />
    <alias alias="DbContextRepository" type="GenericRepository.DbContextRepository`1, GenericRepository" />
   
    <alias alias="User" type="MvcWithUnityTest.Models.User, MvcWithUnityTest.Models" />
    <alias alias="DbEntities" type="MvcWithUnityTest.Models.DbEntities, MvcWithUnityTest.Models" />

    <container name="default">
      <register type="IRepository[User]" mapTo="DbContextRepository[User]">
        <lifetime type="HierarchicalLifetimeManager" />
        <constructor>
          <param name="context" dependencyType="DbEntities">
          </param>
        </constructor>
      </register>

    </container>
  </unity>
 
</configuration>然后在 Global.asax.cs 里调用  Bootstrapper.Initialise(); 即可。

另外，需要注意的是 <register type="IRepository[User]" mapTo="DbContextRepository[User]"> 里加上了  <lifetime type="HierarchicalLifetimeManager" />
这样在 Controller 生命周期结束时才会调用 Dispose。（待展开）

再来看看 Controller 的实现：

根据上面的配置文件：<register type="IRepository[User]" mapTo="DbContextRepository[User]">
[Dependency] 标识的 UserRepository 会在 Controller 请求时被注入实例。

[csharp] print?public class HomeController : Controller 
 { 
     [Dependency] 
     public IRepository<User> UserRepository { get; set; } 
 
     public ActionResult Index() 
     { 
         ViewBag.Message = "ASP.NET MVC3 With Unity.MVC3!"; 
         var users = UserRepository.GetAll(); 
         return View(users);
