不知道这是否可行.
我需要根据枚举值返回正确的服务实现.所以手工编码的实现将如下所示：
public enum MyEnum
{
One,Two
}
public class MyFactory
{
public ITypeIWantToCreate Create(MyEnum type)
{
switch (type)
{
case MyEnum.One
return new TypeIWantToCreate1();
break;
case MyEnum.Two
return new TypeIWantToCreate2();
break;
default:
return null;
}
}
}
返回的实现具有额外的依赖关系,需要通过容器注入,所以手工轧制的工厂将无法正常工作.
这是可能的,如果是,注册会是什么样子？
解决方法
如果将组件注册到容器中,将枚举值指定为组件ID,则可以考虑使用此方法
public class ByIdTypedFactoryComponentSelector : DefaultTypedFactoryComponentSelector
{
protected override string GetComponentName(MethodInfo method,object[] arguments)
{
if (method.Name == "GetById" && arguments.Length > 0 && arguments[0] is YourEnum)
{
return (string)arguments[0].ToString();
}
return base.GetComponentName(method,arguments);
}
}
比ByIdTypedFactoryComponentSelector将用作您的Typed工厂的Selector
public enum YourEnum
{
Option1
}
public IYourTypedFactory
{
IYourTyped GetById(YourEnum enumValue)
}
container.AddFacility<TypedFactoryFacility>();
container.Register
(
Component.For<ByIdTypedFactoryComponentSelector>(),Component.For<IYourTyped>().ImplementedBy<FooYourTyped>().Named(YourEnum.Option1.ToString()),Component.For<IYourTypedFactory>()
.AsFactory(x => x.SelectedWith<ByIdTypedFactoryComponentSelector>())
.LifeStyle.Singleton,...
