如何在注册时将组件实例化为Singleton？ [英] How do I Instantiate component as Singleton at registration?

问题描述

我可以想象这可能在Castle中很简单，但是我是该技术的新手，并且已经在谷歌上搜索了好几个小时而没有运气！

I can imagine this might be quite straight forward to do in Castle but I'm new to the technology and have been Googling for hours with no luck!

I具有以下内容：

container.Register(
Component.For<MySpecialClass>().UsingFactoryMethod(
    () => new MySpecialClass()).LifeStyle.Singleton);

现在很正确，这是延迟加载的，即传递给UsingFactoryMethod（）的lambda表达式是在我真正要求Castle解析我的类实例之前，不会执行该程序。

Now quite rightly this is being lazy-loaded, i.e. the lambda expression passed in to UsingFactoryMethod() isn't being executed until I actually ask Castle to Resolve me the instance of the class.

但是我希望Castle在注册实例后立即创建它。

But I would like Castle to create the instance as soon as I have registered it. Is this possible?

推荐答案

您可以像这样使用内置的Startable工具：

You can just use the built it Startable facility like so:

container.AddFacility<StartableFacility>();
container.Register(Component.For<MySpecialClass>().LifeStyle.Singleton.Start());
