Question

I m trying to implement a UoW like shown here: https://blog.iannelson.uk/wcf-global-exception-handling/

但是,我可以说,如何把它同自治省联系起来。我绝对没有开始的想法。

http://autofac.readthedocs.org/en/latest/integration/wcf.html” rel=“nofollow noretinger” http://autofac.readthedocs.org/en/latest/integration/wcf.html。

但是,要注入或增加IEndpointBehavior? 无

如果能有更好的办法执行联盟,我想听说。

<><>Edit>:

现在我刚刚做:

builder.RegisterType(typeof (UnitOfWork))
    .As(typeof (IUnitOfWork))
    .InstancePerLifetimeScope()
    .OnRelease(x =>
    {
        Trace.WriteLine("Comitted of UoW");
        ((IUnitOfWork) x).Commit();
        // OnRelease inhibits the default Autofac Auto-Dispose behavior so explicitly chain to it
        x.Dispose(); 
    });

虽然我不知道这是否是一种可以接受的方式,但似乎像一个黑客一样:

似乎似乎有可能在WCF中运行UoW:

我在此张贴了我的解决方法:。 http://www.philliphaydon.com/2011/11/06/unit-of-work-with-wcf-and-autofac/。

我已经找到了解决这一问题的办法,如果不出现错误,就只需要工作单位。

登记在自治州劳动监察员职业范围

    builder.RegisterType(typeof (UnitOfWork))
    .As(typeof (IUnitOfWork)).InstancePerLifetimeScope();

之后,我创建了一个综合点名Behavior和一位ErrorHandler。

public class UnitOfWorkEndpointBehavior : BehaviorExtensionElement, IEndpointBehavior
{
    public void Validate(ServiceEndpoint endpoint)
    {
    }

    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    {
        var unitOfWorkInstanceHandler = new UnitOfWorkInstanceHandler();

        endpointDispatcher.ChannelDispatcher.ErrorHandlers.Add(unitOfWorkInstanceHandler);
        endpointDispatcher.DispatchRuntime.InstanceContextInitializers.Add(unitOfWorkInstanceHandler);
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
    }

    protected override object CreateBehavior()
    {
        return new UnitOfWorkEndpointBehavior();
    }

    public override Type BehaviorType
    {
        get { return typeof (UnitOfWorkEndpointBehavior); }
    }
}



public class UnitOfWorkInstanceHandler : IInstanceContextInitializer, IErrorHandler
{
    private bool _doCommit = true;

    public void Initialize(InstanceContext instanceContext, Message message)
    {
        instanceContext.Closing += CommitUnitOfWork;
    }

    void CommitUnitOfWork(object sender, EventArgs e)
    {
        //Only commit if no error has occured
        if (_doCommit)
        {
            //Resolve the UnitOfWork form scope in Autofac
            OperationContext.Current.InstanceContext.Extensions.Find<AutofacInstanceContext>().Resolve<IUnitOfWork>().Commit();
        }
    }

    public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
    {
        _doCommit = false;
    }

    public bool HandleError(Exception error)
    {
        _doCommit = false;
        return false;
    }
}

The registration of the Endpoint Behavior in web.config

<system.serviceModel>
    ...
    <extensions>
      <behaviorExtensions>
        <add name="UnitOfWork" type="Namespace.UnitOfWorkBehavior, Namespace"/>
      </behaviorExtensions>
    </extensions>
      <behaviors>
        <endpointBehaviors>
          <behavior name="">
            <UnitOfWork/>
          </behavior>
        </endpointBehaviors>
    ...
    </behaviors>
    ...
</system.serviceModel>
