WCF With StructureMap

渐渐用惯了Structure，却发现不能直接支持Wcf。

就着手查查资料：http://lostechies.com/jimmybogard/2008/07/30/integrating-structuremap-with-wcf/

上面的大神不喜欢XML，直接无视XML方式，我倒。

看来能自己动手：

 创建 StructureMapServiceBehavior

 
    public class StructureMapServiceBehavior : IServiceBehavior
    {
        public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
        {
            foreach (ChannelDispatcherBase cdb in serviceHostBase.ChannelDispatchers)
            {
                ChannelDispatcher cd = cdb as ChannelDispatcher;
                if (cd != null)
                {
                    foreach (EndpointDispatcher ed in cd.Endpoints)
                    {
                        ed.DispatchRuntime.InstanceProvider =
                            new StructureMapInstanceProvider(serviceDescription.ServiceType);
                    }
                }
            }
        }

        public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase,
            Collection endpoints, BindingParameterCollection bindingParameters)
        {
        }

        public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
        {
        }
    }

  创建 StructureMapInstanceProvider

    public class StructureMapInstanceProvider : IInstanceProvider
    {
        private readonly Type _serviceType;

        public StructureMapInstanceProvider(Type serviceType)
        {
            _serviceType = serviceType;
        }

        public object GetInstance(InstanceContext instanceContext)
        {
            return GetInstance(instanceContext, null);
        }

        public object GetInstance(InstanceContext instanceContext, Message message)
        {
            var obj = ObjectFactory.GetInstance(_serviceType);
            //Console.WriteLine(obj.GetHashCode());
            return obj;
        }

        public void ReleaseInstance(InstanceContext instanceContext, object instance)
        {
        }
    }

  创建 StructureMapBehaviorExtension

    public class StructureMapBehaviorExtension : BehaviorExtensionElement
    {

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

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

  然后设置app.config

   简单写一个宿主程序

 
class Program
    {
        static void Main(string[] args)
        {
            ObjectFactory.Initialize( inti =>
            {
                inti.For()Use();
            }
            );

            ServiceHost host = new ServiceHost(typeof(WcfStructureMap3.Service1));
            host.Open();

            Console.WriteLine("服务启动");
            
            Console.ReadLine();
        }
    }
