Question

是。这是一个与我如何要求Castle Windsor解决我的ISession有关的问题，但我已经重读了5次这样的代码，并且仍然无法弄清楚它有什么问题。

下面是我相当标准的NHibernate工具，除了我注册的最后两个组件：

 public class NHibernateFacility : AbstractFacility
    {
        protected override void Init()
        {
            var config = new Configuration().Configure();
            Kernel.Register(
                Component.For<ISessionFactory>()
                    .UsingFactoryMethod((kernel, context) => config.BuildSessionFactory()),
                Component.For<ISession>()
                    .UsingFactoryMethod((kernel, context) => kernel.Resolve<ISessionFactory>().OpenSession())
                    .LifestylePerWebRequest(),
                     Component.For<IStatelessSession>()
                    .UsingFactoryMethod((kernel, context) => kernel.Resolve<ISessionFactory>().OpenStatelessSession())
                    .LifestylePerWebRequest(),
                    Component.For<StatefulSessionWrapper>().LifestylePerWebRequest(),
                    Component.For<StatelessSessionWrapper>().LifestylePerWebRequest()
                );
        }
    }

StatefulSessionWrapper / StatelessSessionWrapper充当ISession / IStateless会话的...包装器，如下所示：

public class StatefulSessionWrapper : ISessionWrapper
    {
        public StatefulSessionWrapper(ISession session)
        {
            this.Session = session;
        }

        private readonly ISession Session;

        #region ISessionWrapper Members

        public ITransaction BeginTransaction()
        {
            return Session.BeginTransaction();
        }

        public ITransaction BeginTransaction(IsolationLevel isolationLevel)
        {
            return Session.BeginTransaction(isolationLevel);
        }

        public ITransaction Transaction { get { return Session.Transaction; } }

        public bool IsConnected
        {
            get { return Session.IsConnected; }
        }

        public bool IsOpen
        {
            get { return Session.IsOpen; }
        }

        #endregion
    }

这样，我可以使用单个动作过滤器，它只处理NHibernate会话的事务部分：

public class NHibernateActionFilter<T> : Castle.MonoRail.Framework.IFilter where T:ISessionWrapper
    {
        private readonly T NHibernateSession;

        public NHibernateActionFilter(T session)
        {
            if (session != null)
                NHibernateSession = session;
            else
                throw new NullReferenceException("Session is null");
        }

        #region IFilter Members

        public bool Perform(ExecuteWhen exec, IEngineContext context, IController controller, IControllerContext controllerContext)
        {
            if (exec == ExecuteWhen.BeforeAction)
            {
                NHibernateSession.BeginTransaction();
                return true;
            }
            if (exec == ExecuteWhen.AfterAction)
            {
                if (NHibernateSession.Transaction == null || !NHibernateSession.Transaction.IsActive)
                    return false;
                if (context.LastException != null)
                {
                    NHibernateSession.Transaction.Rollback();
                    return false;
                }
                else
                {
                    NHibernateSession.Transaction.Commit();
                    return true;
                }

            }
            return false;
        }

        #endregion
    }

简单地使用它：

    [Filter(ExecuteWhen.Always, typeof(NHibernateActionFilter<StatefulSessionWrapper>), ExecutionOrder = 1)]
    [Filter(ExecuteWhen.BeforeAction, typeof(AuthenticationFilter), ExecutionOrder = 2)]
    [Layout("Default"), Rescue("Default")]
    public abstract class NHibernateController : SmartDispatcherController
    {
        public NHibernateController(ISession session)
        {
            this.NHibernateSession = session;
        }

        protected readonly ISession NHibernateSession;
        ..................

唯一的问题？

这是救援页面。请参阅下面的例外情况

的ObjectDisposedException

消息：会话已关闭！对象名称：'ISession'。

因此，很明显NHibernateActionFilter获得了一个封闭的会话。但据我说，它不应该。 HALP。

嗯，事实证明，我忘了添加我的动作过滤器他们正确的生活方式，因此让温莎让他们单身......
