NHibernate sql查詢實際上沒有對數據庫生效

Question

我在這裏有一些奇怪的問題，我在調試時遇到了麻煩。這個應用程序以前工作正常，但自改變nhibernate配置/ sessoin管理我已經以某種方式打破它，並不能鍛鍊在哪裏。

網頁和他們的帖子都似乎工作正常，更改保存到數據庫，而不是。本次交易/會話由我已經做了的HttpModule處理：

public class NHibernateSessionModule: IHttpModule 
{ 
    private INHibernateRequest _nhibRequest; 
    public void Init(HttpApplication context) 
    { 
     context.BeginRequest += new EventHandler(BeginTransaction); 
     context.EndRequest += new EventHandler(CommitAndCloseSession); 
     Console.WriteLine("Init Nhibernate module"); 
    } 

    /// <summary> 
    /// Opens a session within a transaction at the beginning of the HTTP request. 
    /// This doesn't actually open a connection to the database until needed. 
    /// </summary> 
    private void BeginTransaction(object sender, EventArgs e) 
    { 
     _nhibRequest = new NHibernateRequest(NHibernateSessionManager.Instance); 
     _nhibRequest.Start(); 
    } 

    /// <summary> 
    /// Commits and closes 
    /// </summary> 
    private void CommitAndCloseSession(object sender, EventArgs e) 
    { 
     _nhibRequest.Commit(); 
    } 

    public void Dispose() { } 
} 

這INhibernateRequest是我的自定義DLL，它的作用是：

public class NHibernateRequest : INHibernateRequest 
{ 
    private ITransaction _currentTransaction; 
    private SessionFunctions _sessionFunctions; 

    public NHibernateRequest(SessionFunctions sessionFunctions) 
    { 
     _sessionFunctions = sessionFunctions; 
    } 

    /// <summary> 
    /// Starts a session and transaction 
    /// </summary> 
    public void Start() 
    { 
     _sessionFunctions.OpenSession(); 
     _currentTransaction = _sessionFunctions.CurrentSession.Transaction; 
     _currentTransaction.Begin(); 
    } 

    /// <summary> 
    /// Closes a session and transaction 
    /// </summary> 
    public void Commit() 
    { 

     try 
     { 
      if (_currentTransaction.IsActive) 
      { 
       _currentTransaction.Commit(); 
      } 
     } 
     finally 
     { 
      _sessionFunctions.CloseSession(); 
     } 



    } 
} 

基本會話管理。這一切似乎對.aspx文件（網頁表單）正常工作。但是我有一個被調用的Web服務，它創建了一個新的實體。我的域模型主要圍繞「形式」和「問題」，這個Web服務創建了一個帶有一些問題的新表單。

我想也許這個Web服務並沒有開火的處理程序，所以我把會話東西手動（是的，這是一個有點dodgey但它只是暫時的測試）

 [WebMethod] 
    public bool CreateFormForProject(string jobNumber) 
    { 
     INHibernateRequest _nhibRequest = new NHibernateRequest(NHibernateSessionManager.Instance); 
     _nhibRequest.Start(); 
     try 
     { 
      ServiceLayer.FormsService.CreatePmqccFormForJob(jobNumber); 
      _nhibRequest.Commit(); 
      return true; 
     } catch 
     { 
      _nhibRequest.Commit(); 
      return false; 
     } 
    } 

總是Web服務返回這是真的，所以沒有拋出異常。

所以然後我試圖在網頁上做一個按鈕，使得這個調用然後顯示結果。這似乎創建了它，因爲它顯示了結果，但是當我刷新頁面時，實體不再存在，並且它從來不在數據庫中，所以我猜它必須緩存它以用於該請求。

所以我打開SQL輸出，並配置log4net吐出調試輸出窗口。這是發生了什麼：

這正是預期的，但數據庫不會改變！ SQL必須回滾或其他東西。我試着在_nhibRequest.Commit（）調用之後設置一個斷點，它說事務已經提交。

所以現在我很難過，我該如何調試呢？或者任何人都可以看到我在這裏做錯的根本？

我終於搞定了。這實際上是與這個SO問題： NHIbernate affecting non-nhibernate queries?

我的破解是要提交併重新打開交易，這是在這裏造成的問題。我已經改變它做一個Flush，它似乎工作正常，但我很樂意爲這個問題找到一個合適的解決方案。
