拦截器可以按固定顺序链接

对于这样的注册：

var container = new WindsorContainer();
container.Register(
    Component.For<FirstInterceptor>(),
    Component.For<SecondInterceptor>(),
    Component.For<ThirdInterceptor>(),

    Component.For<IService>()
        .ImplementedBy<Service>()
        .Interceptors<FirstInterceptor>()
        .Interceptors<SecondInterceptor>()
        .Interceptors<ThirdInterceptor>());

var service = container.Resolve<IService>();
service.CreateOrder(new Order());

拦截器具有以下精神：

public class FirstInterceptor : IInterceptor
{
    public void Intercept(IInvocation invocation)
    {
        Console.WriteLine("First!");
        invocation.Proceed();
        Console.WriteLine("First.");
    }
}

并通过以下方式实施服务：

public interface IService
{
    void CreateOrder(Order orderToCreate);
}

public class Service : IService
{
    public void CreateOrder(Order orderToCreate)
    {
        Console.WriteLine("Creating order...");

        // ...
    }
}

我们可以观察输出，它会演示以固定顺序创建的拦截器将按以下顺序执行：

First!
Second!
Third!
Creating order...
Third.
Second.
First.
