castle windsor学习-----Inline dependencies 依赖

应用程序中的很多组件都会依赖其他的服务组件，很多依赖一些不合法的组件或者容器中没有的组件，例如int类型、string类型、TimeSpan类型

Windsor支持以上的场景，注册API有DependsOn方法。该方法接收一个参数（由Dependency类的静态方法返回值提供）

1. 支持静态依赖 Dependency.OnValue

var twitterApiKey = @"the key goes here";

container.Register(
    Component.For<ITwitterCaller>().ImplementedBy<MyTwitterCaller>()
        .DependsOn(Dependency.OnValue("APIKey", twitterApiKey))
);

这个例子通过名称进行依赖匹配，它将提供对应的值给MyTwitterCaller类中名为“APIKey”的属性或者构造函数参数

2.通过类型依赖

var config = new TwitterApiConfiguration {
    // set all the properties here...
};

container.Register(
    Component.For<ITwitterCaller>().ImplementedBy<MyTwitterCaller>()
        .DependsOn(Dependency.OnValue<TwitterApiConfiguration>(config))
);

3. 设置属性 Setting up properties: Property.ForKey()

container.Register(
    Component.For<ICustomer>().ImplementedBy<CustomerImpl>()
        .DependsOn(Property.ForKey("Name").Eq("Caption Hook"), Property.ForKey("Age").Eq(45)));

4. 明确的服务依赖 Dependency.OnComponent()

container.Register(
    Component.For<ITransactionProcessingEngine>().ImplementedBy<TransactionProcessingEngine>()
        .DependsOn(Dependency.OnComponent("Logger", "secureLogger"))
);

5. 依赖配置文件 appSettings dependencies: Dependency.OnAppSettingsValue()

container.Register(
    Component.For<ITwitterCaller>().ImplementedBy<MyTwitterCaller>()
        .DependsOn(Dependency.OnAppSettingsValue("timeout", "twitterApiTimeout"))
);

6.

container.Register(
    Component.For<MainViewModel>()
        .DependsOn(Dependency.OnResource<MyApp.Properties.Resources>("DisplayName", "MainWindowTitle"))
);

Embedded resource dependencies: Dependency.OnResource()

7. Supplying dynamic dependencies

container.Register(
    Component.For<ClassWithArguments>()
        .LifestyleTransient()
        .DynamicParameters((k, d) => d["createdTimestamp"] = DateTime.Now)
);
