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!
