NHibernate 对 BeginRequest 和 EndRequest 的会话处理
我正在 BeginRequest 上打开一个会话，并尝试在 EndRequest 上关闭它。我偶尔会看到如下错误：
Possible nonthreadsafe access to session
at NHibernate.Action.EntityDeleteAction.Execute()
at NHibernate.Engine.ActionQueue.Execute(IExecutable executable)
at NHibernate.Engine.ActionQueue.ExecuteActions(IList list)
at NHibernate.Engine.ActionQueue.ExecuteActions()
at NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions(IEventSource session)
at NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event)
at NHibernate.Impl.SessionImpl.Flush()
at ACC.Web.Modules.NHibernateSessionModule.CommitSession(ISession session)
at ACC.Web.Modules.NHibernateSessionModule.ApplicationEndRequest(Object sender, EventArgs e)
at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
根据这个问题 ASP.NET 请求总是在同一线程上 BeginRequest 和 EndRequest 吗？，我无法确定 BeginRequest 和 EndRequest 是否会在同一线程上触发。我应该如何处理打开和关闭 NHibernate 会话以避免出现这些错误？
谢谢！

I'm opening a session on a BeginRequest and attempting to close it on an EndRequest. I'm sporadically seeing an error that looks like this:
Possible nonthreadsafe access to session
at NHibernate.Action.EntityDeleteAction.Execute()
at NHibernate.Engine.ActionQueue.Execute(IExecutable executable)
at NHibernate.Engine.ActionQueue.ExecuteActions(IList list)
at NHibernate.Engine.ActionQueue.ExecuteActions()
at NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions(IEventSource session)
at NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event)
at NHibernate.Impl.SessionImpl.Flush()
at ACC.Web.Modules.NHibernateSessionModule.CommitSession(ISession session)
at ACC.Web.Modules.NHibernateSessionModule.ApplicationEndRequest(Object sender, EventArgs e)
at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
According to this question Do ASP.NET Requests always BeginRequest and EndRequest on the same thread?, I can't be sure that BeginRequest and EndRequest will fire on the same thread. How should I handle opening and closing NHibernate sessions so that I don't get these errors?
Thanks!

如果您使用任何 IoC 容器，您可以在控制器构造函数上接收 ISession。
我通常在方法上使用属性，例如 这个
If you use any IoC container, you can receive an ISession on controller constructor.
I usually use attribute on method, like this
