Question

我正在迁移我的mvc Web应用程序以使用Nhibernate Facility进行管理 Nhibernate会议。

我遇到了这个奇怪的问题;

当我在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。我没有会话异常。

如果我不将此添加到web.config延迟加载工作正常。就温莎而言，一切都是好的容器和注册Nhibernate Facility去。 NHibernate的设施能够提供会话管理器和Windsor容器能够解决对象。

当然，没有SessionWebModule Nhibernate Facility几乎没用对我而言，在这种情况下，它无法正确管理会话。我看到datareader是已经开放的类型异常好不好..

我陷入困境，需要紧急解决这个问题感谢你的任何帮助。

我在下面的部分配置和代码中包括提供更多信息

的Web.config：

<castle>
        <facilities>
            <facility id="nhibernatefacility" isWeb="false"
type="Castle.Facilities.NHibernateIntegration.NHibernateFacility,
Castle.Facilities.NHibernateIntegration">
                <factory id="nhibernate.factory">
                    <settings>
                        <item

Answer 1

这是设计的。你必须保持你的会话开放。

如果您正在使用网络，我建议您在请求开始时打开会话，并在结束时关闭它。

Answer 2

如果你正在使用MVC，我使用动作过滤器关闭我的nhibernate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......而SessionSource.EndContextSession（）方法本质上是调用：

    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();
            }
        }
    }

我认为您必须将isWeb属性设置为true：

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