Autofac：批量注册开放类型 [英] Autofac: Batch registration of open-generic types

问题描述

我得到了具有许多实现 IHandler< TCommand> 的具体类型的程序集，例如：

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.
    }
}

当前，我正在将它们逐个注册为

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...

命令处理程序是使用构造函数注入来注入，如下所示：

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;
    }
}

是否可以批量注册我的所有处理程序

Is there a way to batch register all my handlers in an easy way using Autofac?

推荐答案

与Jim的答案类似，但要利用 AsClosedTypesOf ：

In a similar style to Jim's answer but taking advantage of AsClosedTypesOf:

Assembly[] assemblies = GetYourAssemblies();

builder.RegisterAssemblyTypes(assemblies)
    .AsClosedTypesOf(typeof(IHandler<>));
