使用Fluent界面从头开始在Castle Windsor中注册所有课程 [英] Register all classes from base on up in Castle Windsor using Fluent interface

问题描述

我有一个抽象基类 Search 。抽象类 IndexedRepositorySearch 源自 Search 。 FacetSearch 的抽象类来自 IndexedRepositorySearch 。具体类 IngredientFacetSearch 和 RecipeFacetSearch 属于 FacetSearch 。

I have an abstract base class Search. An abstract class IndexedRepositorySearch descends from Search. An abstract class FacetSearch descends from IndexedRepositorySearch. Concrete classes IngredientFacetSearch and RecipeFacetSearch descend from FacetSearch.

当前，我们正在将 Search 产生的所有内容注册到温莎城堡：

Currently we're registering everything that descends from Search with Castle Windsor as follows:

AllTypes.FromAssembly(assembly)
        .BasedOn<Search.Search>()
        .WithServiceBase()
        .WithServiceSelf()
        .LifestyleTransient()
        .AllowMultipleMatches()

然后我们打电话

_container.ResolveAll<FacetSearch>(new { searchInput = input, searchResults });

它无法解析容器中的任何内容。当所有内容都已注册后在容器上放置一个断点并在调试器中检查 AllComponents 时，我同时看到了 IngredientFacetSearch 和 RecipeFacetSearch ，但是它们每个都只有两个与之关联的服务：它们的自身和基础的 Search 。考虑到他们在 .WithServiceBase（）和 .WithServiceSelf（）中注册的期望。

It does not resolve anything from the container. When I put a breakpoint on the container after everything has been registered and check AllComponents in the debugger, I see both IngredientFacetSearch and RecipeFacetSearch, but they each only have two Services associated with them: their self and Search, their base. Which you would expect given that they registered with .WithServiceBase() and .WithServiceSelf().

所以问题是如何通过调用 ResolveAll< FacetSearch>（）使他们解决？

So the question is how to get them to resolve by calling ResolveAll<FacetSearch>()?

我敢肯定这很简单，但是如果我能找到它，我会很惊讶。

I'm sure it's something simple but I'll be darned if I can find it.

请先谢谢。

推荐答案

对此我们有一个类似的问题，但是只需要注册第一个抽象的库即可。我使用 WithServiceSelect 解决了这个问题，但将其包装成扩展方法以供使用：

We had a simliar problem to this, but only needed to register the first base which was abstract. I solved it using WithServiceSelect but wrapped it up into an extension method to be used so:

AllTypes.FromAssembly(assembly)
        .BasedOn<Search.Search>()
        .WithServiceLastAbstractBase(),

扩展方法的定义为：

public static BasedOnDescriptor WithServiceLastAbstractBase(this BasedOnDescriptor basedOn)
{
    return basedOn.WithServiceSelect(selectLastAbstractBase);
}

private static IEnumerable<Type> selectLastAbstractBase(Type type, Type[] basetypes)
{
    var baseType = type;

    do
    {
        baseType = baseType.BaseType;
    } while (baseType != null && !baseType.IsAbstract);

    if (baseType == null)
    {
        throw new ArgumentException("There are no abstract base types for: " + type);
    }

    return new [] { baseType };
}
