I am trying to decorate my command handlers using castle windsor but it
seems that my registrations are not correct as the class is not decorated.
the other question I have is should my decorators live in the composition
root or in the same assembly of the class that they are decorating?
right now I have moved them to the composition root as castle windsor was
trying to register my decorators along with the other classes and I would
get the error:
*Component
TempSearch.Command.Data.Decorators.TransactionCommandHandlerDecorator`1
could not be registered. There is already a component with that name. Did
you want to modify the existing component instead? If not, make sure you
specify a unique name.*
another issue is that I am declaring my IDbConnection as per web request
and my commandHandlers depend on my IDbConnection but the command handlers
are being registered as singletons even though I explicitly declare them as
per web request.
I have the following installer:
internal class CommandsInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container,
IConfigurationStore store)
{
container.Register(
Component.For<IDbConnection>()
.UsingFactoryMethod(() =>
ConnectionHelper.GetOpenDbConnection(Connection.DatabaseName.ReedOnline))
.LifestylePerWebRequest());
container.Register(
Classes
.FromAssemblyContaining<EcruiterCommands>()
.Where(t => t.Name.EndsWith("Commands"))
.WithService
.AllInterfaces().LifestylePerWebRequest());
container.Register(
Classes
.FromAssemblyContaining<EcruiterCommands>()
.BasedOn(typeof (ICommandHandler<>))
.WithService.AllInterfaces()
.LifestylePerWebRequest());
container.Register(Component.For(typeof(ICommandHandler<>))
.ImplementedBy(typeof(TransactionCommandHandlerDecorator<>))
.LifestylePerWebRequest());
//var metadataProviderContributorsAssemblies = new[]
{typeof (EcruiterCommands).Assembly};
}
}
and this is my decorator:
namespace TempSearch.Ioc.Decorators.CommandHandlers
{
public class TransactionCommandHandlerDecorator<TCommand> :
ICommandHandler<TCommand>
{
private readonly ICommandHandler<TCommand> decorated;
public
TransactionCommandHandlerDecorator(ICommandHandler<TCommand> decorated)
{
this.decorated = decorated;
}
public void Handle(TCommand command)
{
using (var scope = new TransactionScope())
{
decorated.Handle(command);
scope.Complete();
}
}
}
}
