我正在迁移我的 mvc Web 应用程序以使用 Nhibernate Facility 来管理 Nhibernate 会话。

我遇到了这个奇怪的问题；

当我通过以下方式在 web.config/ httpmodules 下注册 SessionWebModule 时：

<add name="NHibernateSessionWebModule"
type="Castle.Facilities.NHibernateIntegration.Components.Web.SessionWebModule,
Castle.Facilities.NHibernateIntegration" />

系统无法延迟加载对象。我没有任何会话异常。

如果我不将此添加到 web.config 延迟加载工作正常。就重新注册 Windsor 容器和注册 Nhibernate Facility 而言，这一切似乎都还可以。Nhibernate Facility 能够提供会话管理器，Windsor 容器能够解析对象。

当然，没有 SessionWebModule Nhibernate Facility 对我来说几乎没用，因为在这种情况下它无法正确管理会话。我看到 datareader 已经是开放类型的异常，这不好..

我被卡住了，需要紧急解决这个问题，我将不胜感激你的任何帮助。

我在下面包含我的配置和代码的一些部分以提供更多信息

网络配置：

<castle>
        <facilities>
            <facility id="nhibernatefacility" isWeb="false"

                <factory id="nhibernate.factory">

It's by design. You have to keep your session open.

If you are doing web, I suggest you to open the session at the begin of the request and close it at the end.

Get the samples from this article: http://www.codeproject.com/KB/architecture/NHibernateBestPractices.aspx

如果您使用的是 MVC，我会使用操作过滤器来关闭我的休眠会话

public class NHibernateSessionAttribute : ActionFilterAttribute
{
    public NHibernateSessionAttribute()
    {
        Order = 100;
    }


    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
        if (filterContext.IsChildAction) return;

         SessionSource.EndContextSession();
    }
}

SessionSource 是我管理创建会话的地方......并且 SessionSource.EndContextSession() 方法本质上调用：

    public static void EndContextSession()
    {
        var session = CurrentSessionContext.Unbind(Factory);
        if (session != null && session.IsOpen)
        {
            try
            {
                if (session.Transaction != null && session.Transaction.IsActive)
                {
                    // an unhandled exception has occurred and no db commit should be made
                    session.Transaction.Rollback();
                }
            }
            finally
            {
                session.Close();
                session.Dispose();
            }
        }
    }

我相信您必须将isWeb属性设置为true：

<facility id="nhibernatefacility" isWeb="true" type="Castle.Facilities.NHibernateIntegration.NHibernateFacility, Castle.Facilities.NHibernateIntegration">
