未调用StructureMap InstanceInterceptor

我无法在2.5.4版中重现您的问题。这是我的密码。

public interface IPublishResources {}
class PublishResources : IPublishResources {}
public class LoggingInterceptor : InstanceInterceptor
{
    //this interceptor is a silly example of one
    public object Process(object target, IContext context)
    {
        Console.WriteLine("Interceptor Called");
        return context.GetInstance<PublishResources>();
    }
}

public class MyRegistry : Registry
{
    public MyRegistry()
    {
        For<IPublishResources>()
            .Use<PublishResources>()
            .InterceptWith(new LoggingInterceptor());
    }
}

[TestFixture]
public class Structuremap_interception_configuraiton
{
    [Test]
    public void connecting_implementations()
    {
        var container = new Container(cfg =>
        {
            cfg.AddRegistry<MyRegistry>();
        });

        container.GetInstance<IPublishResources>();
    }
}

一个问题。你真的需要在这里使用拦截器吗?如果你只需要定义一个工厂,你可以这样做。

    public interface IPublishResourcesFactory
{
    IPublishResources Create();
}

public class MyRegistry : Registry
{
    public MyRegistry()
    {
        For<IPublishResources>().Use(c =>
        {
            return c.GetInstance<IPublishResourcesFactory>().Create();
        });

        //or

        For<IPublishResources>().Use(c =>
        {
            //other object building code.
            return new PublishResources();
        });
    }
}
