如何将默认的FlushMode更改为在C＃中提交？ [英] How to change default FlushMode to Commit in C#?

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<默认> 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：

• 另一种管理你的NHibernate ISessionFactory的方法


• NHibernate and the Unit of Work
  $ b

  属性ISession.FlushMode定义如下：
  
  

pre> public interface ISession：IDisposable
{
...
///< summary>
///确定在哪些点上Hibernate自动刷新会话。
///
///< / summary>
///
///<备注>
///对于只读会话，将flush模式
///设置为< c> FlushMode.Never< / c>
///在会话开始时（为了达到
///额外的性能）。
///
///< / remarks>
FlushMode FlushMode {get;组; }


它是默认的实现代码片段：

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

在ISessionFactory期间无论如何设置为 not .OpenSession（）调用。





ORIGINAL，而不是工作方法



不支持 < hibernate-configuration> 设置 default_flush_mode 。因此，我们有这些配置属性可用于 < hibernate-configuration> （默认/不流畅的配置设置）：



3.5。可选配置属性
$ b






• default_flush_mode - 默认 FlushMode ，默认为未指定。
  
  
  
  
  • 未指定|从来没有|提交|自动|总是
  
  






和基于例如在这个Q& A：



Fluent NHibernate中的NHibernate配置属性





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.

So, we have these configuration properties available for <hibernate-configuration> (default / not fluent configuration settings):

3.5. Optional configuration properties

• default_flush_mode - The default FlushMode, defaults to Unspecified eg.
  • Unspecified | Never | Commit | Auto | Always

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";
}
