是的。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 次代码,但仍然无法弄清楚它有什么问题。
下面是我相当标准的 NHibernate 设施,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 用作 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,我可以使用单个操作过滤器,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
}
并像这样简单地使用它:
[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。请参阅下面的异常详细信息
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。但在我看来,不应该。哈尔普。
