Question

我在Service Class中通过这个示例POST方法处理请求的上下文中理解为什么我的Manager类为null时遇到了一些麻烦。我注册了管理器和它的依赖关系，就像这个例子，它似乎正在注册。只有这样我才能让它工作，如果我通过apphost引用告诉属性去解析通过容器。谢谢！

public static class TemplateContainer
{
  public const string DomainName = "Template";

  public static Funq.Container Configure(Funq.Container container)
  {

        container.Register<IUOWMongo<TemplateMongoContext>>(DomainName, c =>
             new UOWMongo<TemplateMongoContext>(
                  c.ResolveNamed<string>(Constants.NamedString)
                  )
             ).ReusedWithin(Funq.ReuseScope.Request);

        container.Register<IMongoTemplateRepository>(DomainName, c =>
             new MongoTemplateRepository<TemplateMongoContext>(
                        c.ResolveNamed<IUOWMongo<TemplateMongoContext>>(DomainName)
                  )
             ).ReusedWithin(Funq.ReuseScope.Request);

        container.Register<ITemplateDataManager>(DomainName, c =>
             new TemplateDataManager(c.ResolveNamed<IMongoTemplateRepository>(DomainName))
             ).ReusedWithin(Funq.ReuseScope.Default);

        return container;
  }
}

public class TemplateService : ServiceStack.ServiceInterface.Service
{
  public ITemplateDataManager Manager { get; set; }

  public GetTemplateResponse Post(GetTemplateRequest request)
  {
        var response = new GetTemplateResponse();
        **// Manager is null here!!!
        // Only way I can get it to work is if I do this:
        Manager = AppHostBase.Instance.Container.ResolveNamed<ITemplateDataManager>("Template");**

        return response;
  }
}

Funq中的AutoWiring不会查看命名依赖项。您可以将其更改为注册为普通依赖项：

container.Register<ITemplateDataManager>(c =>
     new TemplateDataManager(c.ResolveNamed<IMongoTemplateRepository>(DomainName))
 );

服务类具有无法解析的公共属性
