温莎城堡PerWebRequest生活方式和Application_EndRequest

问题描述

我注册使用PerWebRequest生活方式有关LINQ2SQL某些组件。我看到他们生成，但我全球的Application_EndRequest方法被调用之前被摧毁。是设计？有谁知道周围的工作？我想打电话给我的UnitOfWork对象承诺的SubmitChanges（）在每一个请求结束。除了使用在Global.asax Application_EndResult，我也试过用IHttpModule的相同的结果。

I'm registering some components related to Linq2Sql using PerWebRequest lifestyle. I see them get created, but they get destroyed before my global's Application_EndRequest method gets called. Is that by design? Does anyone know a work around? I want to call commit on my UnitOfWork object to submitchanges() at the end of every request. In addition to using the Global.asax Application_EndResult, I've also tried an IHttpModule with the same results.

我使用的是城堡2.0。

I'm using Castle 2.0.

下面就是我如何注册我的内容PerWebRequest。我创建保存到L2S的DataContext一个DataCOntextProvider对象。该对象被注入UOW

Here's how I'm registering my stuff with PerWebRequest. I am creating a DataCOntextProvider object that holds onto a L2S DataContext. That object is injected into the UoW.

/// <summary>
        /// Register the IUnitOfWorkManager to resolve to LinqToSqlUnitOfWorkManager per web request
        /// </summary>
        public void RegisterLinq2SqlUnitOfWorkPerWebRequest()
        {
            _container.Register(Component.For<IUnitOfWorkManager>()
              .LifeStyle.PerWebRequest
              .ImplementedBy<LinqToSqlUnitOfWorkManager>());
        }

    /// <summary>
    /// Register the IDataContextProvider to resolve to DataContextProvider per web request
    /// </summary>
    public void RegisterDataContextProviderPerWebRequest()
    {
        _container.Register(Component.For<IDataContextProvider>()
          .LifeStyle.PerWebRequest
          .ImplementedBy<DataContextProvider>());
    }

现在我只是想通过CommonServiceLocator从容器拉UOW（包括CSL和温莎适配器是1.0）从EndRequest是这样的：

Now I am simply trying to pull the UoW from the container via the CommonServiceLocator (both CSL and Windsor Adapter are 1.0) from the EndRequest like this:

 protected void Application_EndRequest(object sender, EventArgs e)
    {
        //ignore unless this is a page (.aspx) or handler (.ashx)
        if (!RequestCanHaveContext())
            return;

        //get the IUnitOfWork manager
        var uow = ServiceLocator.Current.GetInstance<IUnitOfWorkManager>();

        //if we have one, commit changes at the end of the request
        if (uow != null)
        {
            //don't explicitly dispose of uow or we'll get Disposed exceptions on the context
            uow.Commit();
        }

    }

谢谢，

推荐答案

您实施 IUnitOfWorkManager 应实施的IDisposable 在处置通话的SubmitChanges。或者使用自定义的退役提交变化的关注。

your implementation of IUnitOfWorkManager should implement IDisposable and in Dispose call SubmitChanges. Alternatively use custom decommission submit changes concern.
