我们在和 asp.net MVC 应用程序中使用 nhibernate。

我们正在通过 httpModule 实现 Session per Request 模式。

它看起来很简单,但是当我们使用 NHibernate Profiler 运行时,它清楚地表明会话永远不会关闭。

模式似乎很简单......但我不明白为什么会议永远不会结束。

这是我认为很重要的代码。

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();
        }

谁能指出我正确的方向?我应该看什么,模式没有正确实施吗?

我很困惑

谢谢!

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 using 块来释放。
