ninject 2和db4o

我想用db4o使用ninject，我有一個問題。這是從Global.aspxninject 2和db4o

 static IObjectServer _server; 
    protected override void OnApplicationStarted() 
    { 
     AutoMapperConfiguration.Configure(); 
     RegisterRoutes(RouteTable.Routes); 
     RegisterAllControllersIn(Assembly.GetExecutingAssembly()); 
     if (_server == null) 
     { 
      // opening a server for a client/server session     
      IServerConfiguration serverConfiguration = Db4oClientServer.NewServerConfiguration(); 
      serverConfiguration.File.Storage = new MemoryStorage(); 
      _server = Db4oClientServer.OpenServer(serverConfiguration, "myServerDb.db4o", 0); 
     } 
    } 

    public static IObjectContainer OpenClient() 
    { 
     return _server.OpenClient(); 
    } 

    public MvcApplication() 
    { 
     this.EndRequest += MvcApplication_EndRequest; 
    } 

    private void MvcApplication_EndRequest(object sender, System.EventArgs e) 
    { 
     if (Context.Items.Contains(ServiceModule.SESSION_KEY)) 
     { 
      IObjectContainer Session = (IObjectContainer)Context.Items[ServiceModule.SESSION_KEY]; 
      Session.Close(); 
      Session.Dispose(); 
      Context.Items[ServiceModule.SESSION_KEY] = null; 
     } 
    } 

    protected override IKernel CreateKernel() 
    { 
     return new StandardKernel(new ServiceModule()); 
    } 

    public override void OnApplicationEnded() 
    { 
     _server.Close(); 
    }

相關的代碼，這是ServiceModule代碼

 internal const string SESSION_KEY = "Db4o.IObjectServer"; 

    public override void Load() 
    {    
     Bind<IObjectContainer>().ToMethod(x => GetRequestObjectContainer(x)).InRequestScope(); 
     Bind<ISession>().To<Db4oSession>(); 
    } 

    private IObjectContainer GetRequestObjectContainer(IContext Ctx) 
    { 
     IDictionary Dict = HttpContext.Current.Items; 
     IObjectContainer container; 
     if (!Dict.Contains(SESSION_KEY)) 
     { 
      container = MvcApplication.OpenClient(); 
      Dict.Add(SESSION_KEY, container); 
     } 
     else 
     { 
      container = (IObjectContainer)Dict[SESSION_KEY]; 
     } 
     return container; 
    }

然後我嘗試將其注入到我的會議這樣：

 public Db4oSession(IObjectContainer client) 
    { 

     db = client; 
    }

但是，在第一次調用之後，客戶端始終是關閉的 - 因爲它應該是因爲MvcApplication_EndRequest中的代碼。問題在於GetRequestObjectContainer中的代碼只被調用過一次。我究竟做錯了什麼？

此外，MvcApplication_EndRequest總是被調用3次，這是正常的嗎？

謝謝！

'MvcApplication_EndRequest'可能是因爲所謂的請求的三次'favicon.ico'和'的site.css '使用默認的mvc2模板時？查看請求路徑以確保。 – mnemosyn 2010-02-27 17:20:11

你完全正確。謝謝回答！ – user10479 2010-02-28 00:04:01

這似乎做的伎倆......添加InRequestScope其他注射：

Bind<ISession>().To<Db4oSession>().InRequestScope();
