我得到了一个具有许多实现IHandler<TCommand>
的具体类型的程序集,如下所示:
public class MoveCustomerHandler : IHandler<MoveCustomerCommand>
{
void IHandler<MoveCustomerCommand>.Handle(MoveCustomerCommand c)
{
// some business logic for moving a customer.
}
}
目前,我正按照以下方式逐一注册:
builder.RegisterType<MoveCustomerHandler>()
.As<IHandler<MoveCustomerCommand>>();
builder.RegisterType<ProcessOrderHandler>()
.As<IHandler<ProcessOrderCommand>>();
builder.RegisterType<SomeOtherFancyHandler>()
.As<IHandler<SomeOtherFancyCommand>>();
// Many handler registrations here...
使用构造函数注入注入命令处理程序,如下所示:
public class OrderController
{
private readonly IHandler<ProcessOrderCommand> handler;
public OrderController(IHandler<ProcessOrderCommand> handler)
{
this.handler = handler;
}
}
有没有办法使用Autofac以简单的方式批量注册我的所有处理程序?

与Jim的答案类似,但利用AsClosedTypesOf
:
Assembly[] assemblies = GetYourAssemblies();
builder.RegisterAssemblyTypes(assemblies)
.AsClosedTypesOf(typeof(IHandler<>));

你可能想要这样的东西,虽然我不确定IsAssignable()如何用开放的泛型来表现。
Assembly[] assemblies = GetYourAssemblies();
builder.RegisterAssemblyTypes(assemblies)
.Where(t => t.IsAssignableFrom(typeof(IHandler<>)))
.AsSelf()
.AsImplementedInterfaces();
