Question

我在我的项目中使用Castle windsor。我想制作懒惰的解析服务和存储库。示例代码：

public IPersonService PersonService
    {
        get { return _windsorContainer.Resolve<IPersonService>(); }
        set { _windsorContainer.Resolve<IPersonService>(value); }
    }

    public ICityService CityService
    {
        get { return _windsorContainer.Resolve<ICityService>(); }
        set { _windsorContainer.Resolve<ICityService>(value); }
    }

    public IPhoneService PhoneService
    {
        get { return _windsorContainer.Resolve<IPhoneService>(); }
        set { _windsorContainer.Resolve<IPhoneService>(value); }
    }

问题是：解决后，我需要做什么，发布这些。 TNX

修改

My Roof Class是：

public class PhonebookApplication
{
    public WindsorContainer _windsorContainer;

    private void InitializeWindsor()
    {
        _windsorContainer = new WindsorContainer();
        _windsorContainer.Install(Configuration.FromXmlFile("Castle.config"));
    }

    public void Dispose()
    {
        if (_windsorContainer != null)
        {
            _windsorContainer.Dispose();
        }
    }

    private static readonly Lazy<PhonebookApplication> s_Current = new Lazy<PhonebookApplication>(() => new PhonebookApplication(), true);

    public static PhonebookApplication Current
    {
        get { return s_Current.Value; }
    }

    public void ApplicationStart()
    {
        InitializeWindsor();
    }


    //Service count increaseble as your have.
    public IPersonService PersonService
    {
        get { return _windsorContainer.Resolve<IPersonService>(); }
        set { _windsorContainer.Resolve<IPersonService>(value); }
    }

    public ICityService CityService
    {
        get { return _windsorContainer.Resolve<ICityService>(); }
        set { _windsorContainer.Resolve<ICityService>(value); }
    }

    public IPhoneService PhoneService
    {
        get { return _windsorContainer.Resolve<IPhoneService>(); }
        set { _windsorContainer.Resolve<IPhoneService>(value); }
    }
}

}

如果我想在HomeController上调用一个方法，我将方法用作PhoneBookApplication.Current.PhoneService.GetAllList()，然后我想在方法调用完成后调用release current resolved service。如果我将这个类构造函数注入所有工厂类，那么屋顶类依赖于此，因此我不想在任何地方使用ctor注入。

不要这样做 - 您可以使用Windsors TypedFactory faclity代替在运行时解析和发布组件。

您只需创建一个界面：

public interface IPersonServiceFactory
{
    IPersonService Create();

    void Release(IPersonService svc);
}

然后注册AsFactory

container.Register(Component.For<IPersonServiceFactory>().AsFactory());

然后将工厂注入您的班级：

public class SomeClass
{
    public SomeClass(IPersonServiceFactory personServiceFactory)
    {
        IPersonService svc = personServiceFactory.Create();

        // Do some work with the service
        svc.Blah();

        // Now release it
        personServiceFactory.Release(svc);
    }
}

您需要确保在引导代码中向容器添加了类型TypedFactoryFacility：

container.AddFacility<TypedFactoryFacility>();

<强>附录：

如果需要添加任何特殊分辨率逻辑，还可以为工厂界面创建自定义解析器：

container.Register(Component.For<IPersonServiceFactory>().AsFactory(x => x.SelectedWith<PersonServiceFactoryComponentSelector>()));

不要忘记注册

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

实现应该是DefaultTypedFactoryComponentSelector的子类，并且可以覆盖解析组件名称的方法

e.g。您可能希望向Create()工厂方法添加一个参数，以便它使用bool Create(bool useAlternateComponent)来确定是使用一个组件还是另一个组件：

public class DispatcherFactoryComponentSelector : DefaultTypedFactoryComponentSelector
{
    protected override string GetComponentName(System.Reflection.MethodInfo method, object[] arguments)
    {
        if(arguments[0] is bool && (bool)arguments[0] == true)
        // Return a certain component name
        else
        // Return a different component name
    }
}

解决后释放服务
