Nhibernate in asp，net ISession帮助

Question

我们在asp.net MVC应用程序中使用了nhibernate。

我们通过httpModule实现了每个请求的会话模式。

它看起来非常简单，但当我们使用NHibernate事件探查器运行时，它清楚地表明会话永远不会关闭。

模式似乎是直接的forward...but我不明白为什么会话永远不会结束。

下面是我认为重要的代码。

设置事件处理程序：

    context.EndRequest += new EventHandler(this.context_EndRequest);

在处理程序中处理会话

private void context_EndRequest(object sender, EventArgs e)
        {
            netLogHdl.ArchDebug("NHibernateHttpModule.context_EndRequest() ");

            Dispose(0);// we are hitting 2 dbs and thus keep one session for each.
            Dispose(1);

            HttpContextBuildPolicy.DisposeAndClearAll();
        }


private void Dispose(int sessionIndex)
        {
            netLogHdl.ArchStart("NHibernateHttpModule.Dispose", "int sessionIndex=\" + sessionIndex + \")");

            try
            {
                //close the DB session
                string sessManagerName = "";
                string jcdcManager = "JCDC Manager";
                string spamisManager = "Spamis Manager";

                if (sessionIndex == 0)
                    sessManagerName = jcdcManager;
                else
                {
                    sessManagerName = spamisManager;
                }


                ISession oneSession = sessionPerDB[sessionIndex];
                if (oneSession != null)
                {
                    if (sessManagerName == jcdcManager) netLogHdl.ArchDebug(sessManagerName + " oneSession is NOT null");

                    if (oneSession.IsOpen)
                    {
                        // Don't flush - all saves should use transactions and calling Commit does the flush.
                        if (sessManagerName == jcdcManager) netLogHdl.ArchDebug(sessManagerName + " Closing the session");

                        //This will overrite it with the exact same session, if they don't match something weird is going on - EWB
                        oneSession = CurrentSessionContext.Unbind(factoryPerDB[sessionIndex]);
                        oneSession.Close();
                    }
                    else
                    {
                        if (sessManagerName == jcdcManager) netLogHdl.ArchDebug(sessManagerName + " Session is NOT open");
                    }

                    //if ( sessManagerName == jcdcManager ) netLogHdl.ArchDebug( sessManagerName + " Session got Dispose()-ing" );
                    //oneSession.Dispose();
                }
                else
                {
                    if (sessManagerName == jcdcManager) netLogHdl.ArchDebug(sessManagerName + " Session is NULL");
                }

                sessionPerDB[sessionIndex] = null;

            }
            catch (Exception)
            {

                throw;
            }


            netLogHdl.ArchEnd();
        }

有谁能给我指个方向吗？我应该看什么，模式实现不正确吗？

我很迷惑

谢谢!

Answer 1

您应该调用dispose，而不是断开连接或关闭。System.IDisposable实现对象应始终通过调用dispose方法或通过using块来释放。
