For registration like this:
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());
With interceptors in the following spirit:
public class FirstInterceptor : IInterceptor
{
public void Intercept(IInvocation invocation)
{
Console.WriteLine("First!");
invocation.Proceed();
Console.WriteLine("First.");
}
}
And with service implemented in the following way:
public interface IService
{
void CreateOrder(Order orderToCreate);
}
public class Service : IService
{
public void CreateOrder(Order orderToCreate)
{
Console.WriteLine("Creating order...");
// ...
}
}
We can observe output that demonstrates interceptors created in a fixed order are going to be executed in that order:
First!
Second!
Third!
Creating order...
Third.
Second.
First.
