I got an assembly with many concrete types that implement IHandler<TCommand>
, such as the following:
public class MoveCustomerHandler : IHandler<MoveCustomerCommand>
{
void IHandler<MoveCustomerCommand>.Handle(MoveCustomerCommand c)
{
// some business logic for moving a customer.
}
}
Currently, I'm registering them one by one as follows:
builder.RegisterType<MoveCustomerHandler>()
.As<IHandler<MoveCustomerCommand>>();
builder.RegisterType<ProcessOrderHandler>()
.As<IHandler<ProcessOrderCommand>>();
builder.RegisterType<SomeOtherFancyHandler>()
.As<IHandler<SomeOtherFancyCommand>>();
// Many handler registrations here...
The command handlers are injected using constructor injection, as can be seen below:
public class OrderController
{
private readonly IHandler<ProcessOrderCommand> handler;
public OrderController(IHandler<ProcessOrderCommand> handler)
{
this.handler = handler;
}
}
Is there a way to batch register all my handlers in an easy way using Autofac?
In a similar style to Jim's answer but taking advantage of AsClosedTypesOf
:
Assembly[] assemblies = GetYourAssemblies();
builder.RegisterAssemblyTypes(assemblies)
.AsClosedTypesOf(typeof(IHandler<>));
