• Castle Windsor Fluent Registration API


    一对一注册

    直接注册组件

    container.Register(
        Component.For<MyServiceImpl>()
    );
    

    注册接口并提供组件

    container.Register(
        Component.For<IMyService>()
            .ImplementedBy<MyServiceImpl>()
    );
    
    //非泛型重载方法,和上面的效果是一样的
    container.Register(
        Component.For(typeof(IMyService))
            .ImplementedBy(typeof(MyServiceImpl))
    );
    

    注册泛型类

    container.Register(
        Component.For(typeof(IRepository<>)
            .ImplementedBy(typeof(NHRepository<>)
    );
    

    配置组件的声明周期

    container.Register(
       Component.For<IMyService>()
          .ImplementedBy<MyServiceImpl>()
          .LifeStyle.Transient
    );
    

    如果配置LifeStyle,默认的声明周期是Singleton

    同一个接口注册多个组件

    container.Register(
        Component.For<IMyService>().ImplementedBy<MyServiceImpl>(),
        Component.For<IMyService>().ImplementedBy<OtherServiceImpl>()
    );
    

    这种情况下,当容器解析获得组件的时候默认得到的是第一个被注册的,现在是MyServiceImpl,但是我们可以通过IsDefault方法来设置默认组件,

    container.Register(
        Component.For<IMyService>().ImplementedBy<MyServiceImpl>(),
        Component.For<IMyService>().ImplementedBy<OtherServiceImpl>().IsDefault()
    );
    

    这样Resolve将会得到OtherServiceImpl组件,还有一种方法就是给每个组件起名字,然后通过名字Resolve

    container.Register(
        Component.For<IService>().ImplementedBy<Service1>().Named("service1"),
        Component.For<IService>().ImplementedBy<Service2>().Named("service2"));
    
    var service = container.Resolve<IService>("service2");
    

    使用委托作为组件工厂

    container
       .Register(
          Component.For<IMyService>()
             .UsingFactoryMethod(
                () => MyLegacyServiceFactory.CreateMyService())
    );
    

    UsingFactoryMethod方法使注册更灵活,还有一个UsingFactory方法,文档建议不用

    注册组件给多个服务

    container.Register(
        Component.For<IUserRepository, IRepository>()
            .ImplementedBy<MyRepository>()
    );
    

    按约定注册组件

    BasedOn

    container.Register(
        Classes.FromThisAssembly()
            .BasedOn<SmartDispatcherController>()
            .Configure(c => c.Lifestyle.Transient)
    );
    
    BasedOn 注册所有继承它的组件,解析的时候不能用BasedOn基于的类型,也就是说
    
    container.Resolve<SmartDispatcherController>(); 将会抛异常,使用继承它的组件的类型
    

    WithService.Base()

    把最末端的组件注册进去,B继承A,C继承B,把C作为组件注册进去

    WithService.DefaultInterfaces()

    把最末端并且名字包含接口名字的组件注册进去

    WithService.FromInterface()

    container.Register(
    Classes.FromThisAssembly()
    .BasedOn().WithService.FromInterface()
    );

    举例说明
    
    public interface IService {}
    
    public interface ICalculatorService : IService
    {
         float Add(float op1, float op2);
    }
    
    public class CalculatorService : ICalculatorService
    {
         public float Add(float op1, float op2)
         {
             return op1 + op2;
         }
    }
    
    IService实际上作为一个标记接口来达到某种效果(没想到有什么用呢),等价于
    
    container.Register(
        Component.For<ICalculatorService>().ImplementedBy<CalculatorService>()
    );
    
    Resolve的时候也是通过类型ICalculatorService获得组件,通过IService会抛异常
    

    WithService.Self()

    container.Register(
    Classes.FromThisAssembly()
    .BasedOn().WithService.Self()
    );

    举例说明
    
    public interface IService {}
    
    public interface ICalculatorService : IService
    {
         float Add(float op1, float op2);
    }
    
    public class CalculatorService : ICalculatorService
    {
         public float Add(float op1, float op2)
         {
             return op1 + op2;
         }
    }
    
    public class CalculatorService2 : ICalculatorService
    {
         public float Add(float op1, float op2)
         {
             return op1 + op2;
         }
    }
    
    等价于(实践出真知)
    
    container.Register(
        Component.For<CalculatorService>(),
        Component.For<CalculatorService2>()
    );
    

    叠加使用

    Classes.FromThisAssembly()
       .BasedOn<IFoo>()
       .WithService.Self()
       .WithService.Base()
    等价于
    Component.For<IFoo, FooImpl>().ImplementedBy<FooImpl>();
    

    IncludeNonPublicTypes

    把abstract、internal、sealed类都给注册进去了,默认是不注册这些类的,使用时请注意

    Configure method

    container.Register(
        Classes.FromAssembly(Assembly.GetExecutingAssembly())
            .BasedOn<ICommon>()
            .LifestyleTransient()
            .Configure(component => component.Named(component.Implementation.FullName + "XYZ"))
    );
    

    ConfigureFor method

    container.Register(
        Classes.FromThisAssembly()
            .BasedOn<ICommon>()
            .LifestyleTransient()
            .Configure(
                component => component.Named(component.Implementation.FullName + "XYZ")
            )
            .ConfigureFor<CommonImpl1>(
                component => component.DependsOn(Property.ForKey("key1").Eq(1))
            )
            .ConfigureFor<CommonImpl2>(
                 component => component.DependsOn(Property.ForKey("key2").Eq(2))
            )
    );
    还没搞明白
    

    ConfigureIf method

    container.Register(
        Classes.FromThisAssembly()
            .BasedOn<ICommon>()
            .LifestyleTransient()
            .Configure(
                component => component.Named(component.Implementation.FullName + "XYZ")
            )
            .ConfigureIf(
                x => x.Implementation.Name.StarsWith("Common"),
                 component => component.DependsOn(Property.ForKey("key1").Eq(1))
            )
    );
