Question

HeJ小鼠，

我正在开发asp.net Webapi。当我尝试在我的存储库构造函数中注入值时，它会抛出异常。解决依赖关系失败，

type =＆＃34; Controllers.XXXXX＆＃34;，name =＆＃34;（none）＆＃34;

。在解决时发生异常：例外是：

InvalidOperationException - 当前类型IRepository是一个接口，无法构造。你错过了类型映射吗？ -----------------------------------------------

我正在做那样的注册

string modelMapperName = Guid.NewGuid().ToString();
        container.RegisterType<IBulkCopy, BulkCopy>("bulkCopy", new InjectionConstructor("dbo", "test"));

        container.RegisterType<IMapConfigurator, ProductMap>(modelMapperName, new ContainerControlledLifetimeManager());

        container.RegisterType<IModelMapper, ModelAutoMapper>(modelMapperName,
            new ContainerControlledLifetimeManager(), new InjectionConstructor(new ResolvedParameter<IMapConfigurator>(modelMapperName)));

        container.RegisterType<IProductRepository, EProductRepository>("productRepository", new PerResolveLifetimeManager(),
             new InjectionConstructor(
                new ResolvedParameter<IRepositoryFactory>(DatabaseConnection.XXXX)
                , new ResolvedParameter<IModelMapper>(modelMapperName),
                new ResolvedParameter<IBulkCopy>("bulkCopy")));

当我从IProductRepository映射中删除ResolvedParamater时，它可以正常工作。任何人都可以帮助我找出这个问题。

提前致谢
