asp.net – NHibernate线程安全与会话

我以为这是我的课,所以我试图使用不同的方法从这个博客文章http://pwigle.wordpress.com/2008/11/21/nhibernate-session-handling-in-aspnet-the-easy-way/,但我仍然得到相同的问题.我得到的实际错误是：

Server Error in '/AvvioCMS' Application.
failed to lazily initialize a collection,no session or session was closed
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: NHibernate.LazyInitializationException: failed to lazily initialize a collection,no session or session was closed

无论是否打开数据库,但这是主要的祸根.

我把会话管理类放在下面,任何人都可以发现为什么我可能会遇到这些问题？

public interface IUnitOfWorkDataStore
{
    object this[string key] { get; set; }
}


    public static Configuration Init(IUnitOfWorkDataStore storage,Assembly[] assemblies)
    {
        if (storage == null)
            throw new Exception("storage mechanism was null but must be provided");

        Configuration cfg = ConfigureNHibernate(string.Empty);
        foreach (Assembly assembly in assemblies)
        {
            cfg.AddMappingsFromAssembly(assembly);
        }

        SessionFactory = cfg.BuildSessionFactory();
        ContextDataStore = storage;

        return cfg;
    }

    public static ISessionFactory SessionFactory { get; set; }
    public static ISession StoredSession
    {
        get
        {
            return (ISession)ContextDataStore[NHibernateSession.CDS_NHibernateSession];
        }
        set
        {
            ContextDataStore[NHibernateSession.CDS_NHibernateSession] = value;
        }
    }

    public const string CDS_NHibernateSession = "NHibernateSession";
    public const string CDS_IDbConnection = "IDbConnection";

    public static IUnitOfWorkDataStore ContextDataStore { get; set; }

    private static object locker = new object();
    public static ISession Current 
    {
        get 
        {
            ISession session = StoredSession;

            if (session == null) 
            {
                lock (locker)
                {
                    if (DBConnection != null)
                        session = SessionFactory.OpenSession(DBConnection);
                    else
                        session = SessionFactory.OpenSession();

                    StoredSession = session;
                }
            }

            return session;
        }
        set
        {
            StoredSession = value;
        }
    }

    public static IDbConnection DBConnection
    {
        get
        {
            return (IDbConnection)ContextDataStore[NHibernateSession.CDS_IDbConnection];
        }
        set
        {
            ContextDataStore[NHibernateSession.CDS_IDbConnection] = value;
        }
    }

}

我正在使用的实际商店是这样的：

public class HttpContextDataStore : IUnitOfWorkDataStore
{
    public object this[string key]
    {
        get { return HttpContext.Current.Items[key]; }
        set { HttpContext.Current.Items[key] = value; }
    }
}

我在Application_Start上初始化SessionFactory：

NHibernateSession.Init(new HttpContextDataStore(),new Assembly[] { 
                typeof(MappedClass).Assembly});

更新

嗨,嗨,谢谢你的建议,我尝试了一些不同的东西来尝试和简化代码,但我仍然遇到同样的问题,我可能有一个想法为什么.

我根据需要创建会话,但是在我的global.asax中,我正在处理Application_EndRequest上的会话.不过我发现Application_EndRequest在加载页面结束时正在调试中被多次触发.我认为这个事件只是在请求的最后一次启动,但是如果没有,而其他一些项目正试图使用??Session(这是什么错误的抱怨),无论什么奇怪的原因,可能是我的问题,会话仍然是线程安全,它只是被提前处理.

任何人有任何想法？我做了一个谷歌,看到VS开发服务器确实造成这样的问题,但是我通过IIS运行它.
