Func <T>注入Windsor容器

Question

以下是与Autofac配合使用的AspComet项目的代码摘录.

public MessageBus(IClientRepository clientRepository, Func<IMessagesProcessor> messagesProcessorFactoryMethod)
{
    this.clientRepository = clientRepository;
    this.messagesProcessorFactoryMethod = messagesProcessorFactoryMethod;
}

如何Func<IMessagesProcessor> messagesProcessorFactoryMethod用温莎注入" ",是否可能？

谢谢.

Answer 1

Container.Register(
  Component.For<IMessagesProcessor>()
           .ImplementedBy<MessagesProcessor>()
           .Lifetime.Transient,
  Component.For<Func<IMessagesProcessor>>()
           .Instance(() => Container.Resolve<IMessagesProcessor>())
)

这应该够了吧

Answer 2

container.Register(Component.For<Func<Foo>>().Instance(f));

这是一个通过的单元测试，演示了这个概念：

[TestMethod]
public void Test2()
{
    Func<string> f = () => "Hello world";

    var container = new WindsorContainer();
    container.Register(Component.For<Func<string>>().Instance(f));

    var resolvedFunc = container.Resolve<Func<string>>();

    Assert.AreEqual("Hello world", f());
}
