如何将默认的FlushMode更改为在C＃中提交？

问题描述

所以...已经说过了：
$ b $ p如何将 FlushMode 更改为在C＃中提交？

我的意思是，在Fluent NHibernate FlushMode默认设置为Auto。

所以...设置FluentMode为提交，我需要打开会话，然后更改它：

  var someSessionFactory = ... bla bla ..; 
 var session = someSessionFactory.OpenSession（）; 
 session.FlushMode = FlushMode.Commit; 
  

这将工作但是...这意味着我需要调用包含 FlushMode.Commit 每次我是开幕式。
为了让sessionFactory自动化，我有几个包装（意思是只设置一次，然后在打开新的上下文时自动使用它），这意味着我不能每次都直接打开会话而不需要挖掘工厂类型等等。

有没有办法将 FlushMode 从Auto更改为Commit？有没有办法做到这一点 var sessionFactory = Fluently.Configure（）。 ... ？

编辑：

尝试过的第二件事情

pre $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ this._sessionFactory = （）
.Database（
MsSqlConfiguration.MsSql2008
.ConnectionString（this._connectionString）
.AdoNetBatchSize（10）
.QuerySubstitutions（true 1，假0，是'是'，否'N'））
.Cache（c => c.Not.UseSecondLevelCache（）。Not.UseQueryCache（））
.Mappings（m => ;
{
foreach（mappingAssemblies中的程序集asm）
{
m.FluentMappings.AddFromAssembly（asm）;
m.HbmMappings.AddFromAssembly（asm）;

））
.ExposeConfiguration（ModifyConfiguration）
.BuildSessionFactory（）;

var session = _sessionFactory.OpenSession（）;

$ b $ public void ModifyConfiguration（NHibernate.Cfg.Configuration configuration）
{
configuration.Properties [default_flush_mode] = FlushMode.Commit.ToString（）;

我调用了 _sessionFActory.OpenSession（）来查看FlushMode是否已经改变，并且没有。仍然FlushMode是自动，而不是提交。

解决方案

没有办法如何配置默认FlushMode为ISession。我这样做的方式以及常见的方式是进入 ISessionFactory.OpenSession（） （IoC， MVC AOP过滤器，Web API委托），并分配FlushMode （手动）

  var session = SessionFactory.OpenSession（）; 
 session.FlushMode = FlushMode.Commit; 
  

检查以下内容：

• 
  
  

  我们可以这样做：
  
  

   流利的.Configure（）
  。 Database（ConfigureDatabase（））
   .Mappings（ConfigureMapping）
   .ExposeConfiguration（ModifyConfiguration）
   .BuildConfiguration（）; 
   
   
   $ b private void ModifyConfiguration（Configuration configuration）
   {
   configuration.Properties [default_flush_mode] =Commit; 
  } 
    

  
  

  So... already said it:

  How to change FlushMode to Commit in C#?

  I mean, In Fluent NHibernate FlushMode by default is setted as Auto.

  So... to set FluentMode to Commit, I need to open session and then change It:

  var someSessionFactory = ... bla bla ..;
  var session = someSessionFactory.OpenSession();
  session.FlushMode = FlushMode.Commit;
  

  This will work but... this will mean that I need to call method which contains FlushMode.Commit each time I am opening session.To inicialize sessionFactory I have several wraps (meant to set it only once and then auto use it when new context is opened), which means I can't just open session directly every time I want without digging into factory type and etc.

  Is there a way to change default FlushMode from Auto to Commit? Is there a way to do it in var sessionFactory = Fluently.Configure(). ... ?

  EDIT:

  Tried seccond thing

  public void Initialise(params Assembly[] mappingAssemblies)
  {
      this._sessionFactory = Fluently.Configure()
          .Database(
              MsSqlConfiguration.MsSql2008
                  .ConnectionString(this._connectionString)
                  .AdoNetBatchSize(10)
                  .QuerySubstitutions("true 1, false 0, yes 'Y', no 'N'"))
          .Cache(c => c.Not.UseSecondLevelCache().Not.UseQueryCache())
          .Mappings(m =>
          {
              foreach (Assembly asm in mappingAssemblies)
              {
                  m.FluentMappings.AddFromAssembly(asm);
                  m.HbmMappings.AddFromAssembly(asm);
              }
          })
          .ExposeConfiguration(ModifyConfiguration)
          .BuildSessionFactory();
  
      var session = _sessionFactory.OpenSession();
  }
  
  public void ModifyConfiguration(NHibernate.Cfg.Configuration configuration)
  {
      configuration.Properties["default_flush_mode"] = FlushMode.Commit.ToString();
  }
  

  I called _sessionFActory.OpenSession() to see if FlushMode has changed and... Nope. Still FlushMode is Auto, instead of Commit.

  解决方案

  There is no way how to configure default FlushMode for ISession. The way I do that, and the way which could be found in common, is step into ISessionFactory.OpenSession() (IoC, MVC AOP Filter, Web API delegate) and assign the FlushMode (manually)

  var session = SessionFactory.OpenSession();
  session.FlushMode = FlushMode.Commit;
  

  Check these:

  • Yet another way to manage your NHibernate ISessionFactory
  • NHibernate and the Unit of Work Pattern

  The property ISession.FlushMode as defined below:

  public interface ISession : IDisposable
  {
      ...
      /// <summary>
      /// Determines at which points Hibernate automatically flushes the session.
      /// 
      /// </summary>
      /// 
      /// <remarks>
      /// For a readonly session, it is reasonable to set the flush mode 
      ///  to <c>FlushMode.Never</c>
      ///  at the start of the session (in order to achieve some 
      ///       extra performance).
      /// 
      /// </remarks>
      FlushMode FlushMode { get; set; }
  

  and it's the default implementation snippet:

  public sealed class SessionImpl : ...
  {
      ...
      private FlushMode flushMode = FlushMode.Auto;
      ...
  

  is not set anyhow during the ISessionFactory.OpenSession() call.

  ORIGINAL, not working approach

  The documented <hibernate-configuration> setting default_flush_mode is not supported.

  and based e.g. on this Q & A:

  NHibernate config properties in Fluent NHibernate

  we can do:

  Fluently.Configure()
      .Database(ConfigureDatabase())
      .Mappings(ConfigureMapping)
      .ExposeConfiguration(ModifyConfiguration)
      .BuildConfiguration();
  
  ...
  
  private void ModifyConfiguration(Configuration configuration)
  {
      configuration.Properties["default_flush_mode"] = "Commit";
  }
