这是我第一次在这里发帖,相信我,我已经从高处和低处搜索了我的问题的答案,但收效甚微。

背景:我目前已经开始尝试重构我们现有的 SOAP Web 服务(.Net 3.5),以便使用 Ninject 进行一些 IOC 和 DI。我有一个 CacheManager,我试图在 web 方法中初始化它,但是注入似乎没有启动。

我有一个控制台应用程序,它使用以下内容调用 Web 服务:

static void Main(string[] args)
    {
        TestService service = new CachingService.TestService();

        DataResult result = service.GetSomething(1);
    }

网络服务如下:TestService.asmx.cs

[WebMethod(Description = "Get something")]
public DataResult GetSomething(int param)
{
    try
    {
        return this.CacheManager.Get();
    }
    catch (Exception ex)
    {
        throw;
    }
}

Base.cs(TestService.asmx.cs继承Base初始化CacheManager)

public class Base
{
    [Inject]
    public ICacheManager CacheManager
    {
        get
        {
            if (cacheProxy == null)
            {
                cacheProxy = new CacheProxy();
            }
            return cacheProxy.CacheManager;
        }
    }  
}

缓存代理.cs

public class CacheProxy
{
    [Inject]
    public ICacheManager CacheManager { get; set; }
}

缓存管理器.cs

public class CacheManager : ICacheManager
{
   //implements iCacheManager methods
}

App_Start/NinjectWebCommon.cs

private static void RegisterServices(IKernel kernel)
    {
kernel.Bind<ICacheManager>()
            .ToMethod(x => x.Kernel.Get<ICacheManagerFactoryBuilder>().GetCacheManagerFactory().CreateCacheManager())
            .InRequestScope();
}

CacheManagerFactoryBuilder.cs

public class CacheManagerFactoryBuilder : ICacheManagerFactoryBuilder
{
    private ICacheManagerFactory _Factory;

    public CacheManagerFactoryBuilder(ICacheManagerFactory factory)
    {
        _Factory = factory;
    }

    public ICacheManagerFactory GetCacheManagerFactory()
    {
        return _Factory;
    }
}

CacheManagerFactory.cs

public class CacheManagerFactory : ICacheManagerFactory
{
    private readonly ICacheManager Manager;

    public CacheManagerFactory(ICacheManager manager)
    {
        if (this.Manager == null)
        {
            this.Manager = manager;
        }
    }

    public ICacheManager CreateCacheManager()
    {
        return this.Manager;
    }

}  

每次我运行控制台应用程序并点击GetSomething时,CacheManager为空。为什么当我调用 web 方法时没有发生注入?

团队的另一位成员最终在这里的另一个线程中偶然发现了这一点:

如何在 asp.net Web 窗体上实现 Ninject 或 DI?

我所缺少的只是在我的 TestService Web 服务类上继承 WebServiceBase!
