自定义 ResourceProviderFactory 依赖注入 [英] Custom ResourceProviderFactory Dependency Injection

问题描述

在 ASP.NET MVC 中是否有任何地方可以获得对实例化的 ResourceProviderFactory 的引用，以便执行属性注入以添加自定义数据库实现以从中检索资源?

Is there anywhere in ASP.NET MVC where you can get a reference to the ResourceProviderFactory that is instantiated in order to perform Property Injection to add a custom DB Implementation to retrieve the resources from?

我正在加载一个自定义资源提供程序，但我想知道是否有替代使用静态 DI 容器在提供程序中注入依赖项的方法.

I have a custom resource provider being loaded but I wanted to know whether there was an alternative to using a Static DI container to inject the dependency within the Provider.

类似于在 MVC 中为 Role 和 Membership 提供程序注入的方式.

Similar to how you can inject for the Role and Membership providers in MVC.

推荐答案

诀窍是实现一个基础设施组件调用到 MVC 的 DependencyResolver.Current，这样你就可以注册真正的 ResourceProviderFactory 使用您最喜欢的 DI 容器.

The trick is to implement an infrastructure component calls into MVC's DependencyResolver.Current, so you can register the real ResourceProviderFactory using your favorite DI container.

这是一个可以解决问题的类:

Here is such a class that will do the trick:

public class MvcResourceProviderFactory : ResourceProviderFactory
{
    public override IResourceProvider CreateGlobalResourceProvider(
        string classKey)
    {
        return GetFactory().CreateGlobalResourceProvider(classKey);
    }

    public override IResourceProvider CreateLocalResourceProvider(
        string virtualPath)
    {
        return GetFactory().CreateLocalResourceProvider(virtualPath);
    }

    private static ResourceProviderFactory GetFactory()
    {
        var resolver = DependencyResolver.Current;

        var factory = resolver.GetService<ResourceProviderFactory>();

        if (factory != null)
        {
            return factory;
        }

        throw new InvalidOperationException(string.Format(
            "No {0} has been registered in the {1}.",
            typeof(ResourceProviderFactory).FullName,
            DependencyResolver.Current.GetType().FullName));
    }
}

这个类可以配置如下:

<globalization
    resourceProviderFactoryType="MyApp.MvcResourceProviderFactory, MyApp"
    enableClientBasedCulture="true" uiCulture="auto" culture="auto"
/>
