温莎城堡：如何更新组件注册 [英] Castle Windsor: How can I update a components registration

问题描述

如果我已在config中定义：

If I have defined in config:

container.Register(
   Component.For<X.Y.Z.IActivityService>()
            .ImplementedBy<X.Y.Z.ActivityService>()
            .ServiceOverrides(ServiceOverride.ForKey("Listeners").Eq(new [] { typeof(X.Y.Z.DefaultActivityListener).FullName }))
            .LifeStyle.Transient
);

，我希望扩展此配置并将新项添加到Listeners数组属性中，以便最终配置有效：

and I wish to extend this configuration and add a new item to the Listeners array property such that the final configuration is effectively:

container.Register(
   Component.For<X.Y.Z.IActivityService>()
            .ImplementedBy<X.Y.Z.ActivityService>()
            .ServiceOverrides(ServiceOverride.ForKey("Listeners").Eq(new [] { typeof(X.Y.Z.DefaultActivityListener).FullName, "MyOtherListenerID" }))
            .LifeStyle.Transient
);

在首次注册组件时，我必须知道数组的内容，还是可以检索

must I know the contents of the "array" when first registering the component, or can I retrieve the component registration and add to it?

我希望使用装饰器模式实现我的配置，这样我可以构建我的容器，然后根据需要扩展它以适应不同的情况。这意味着我需要能够访问已配置的组件并将其添加到其中。

I wish to implement my config using the decorator pattern such that I can build my container, and then extend it as needed for different scenarios. This means I need to be able to access the already configured components and add to them.

考虑使用一个类 DefaultConfig 返回默认设置，然后返回更多 DecoratedConfig 类之一，这将扩展默认配置。

Was thinking of having a class DefaultConfig which return the default setup and then one of more "DecoratedConfig" classes, that would extend the default config.

所以我会有

IWindsorContaner c = new DecoratedConfig(new DefaultConfig()).InitialiseContainer();

DefaultConfig 将设置 ActivityService 和 DefaultActivityListener （如示例所示）。

DefaultConfig would set up the ActivityService with a DefaultActivityListener (as shown in example).

DecoratedConfig 会识别出已创建 ActivityService 并将其自己的监听器实现添加到 Listeners ActivityService 上的code>数组。

DecoratedConfig would recognise that ActivityService had been created and add its own Listener implementation to the Listeners array on ActivityService.

谢谢。

推荐答案

订阅 Kernel.ComponentModelCreated 事件。您可以从此处更改任何组件参数。请参见此。不必拥有来做到这一点，但这很方便。

Subscribe to the Kernel.ComponentModelCreated event. You can change any component parameter from there. See this. It doesn't have to be a facility who does this, but it's convenient.
