我想用Simple Injector注册Automapper,将它注入控制器:
public class MyController : BaseController
{
private IUnitOfWork unitOfWork;
private IMappingEngine mappingEngine;
public PatientController(IUnitOfWork _unitOfWork, IMappingEngine _mappingEngine)
{
this.unitOfWork = _unitOfWork;
this.mappingEngine = _mappingEngine;
}
}
但是当我尝试注册时
public static void Initialize()
{
//Code for registering our repository class and DI
var container = new Container();
container.Register<IUnitOfWork, UnitOfWork>();
container.Register<IMappingEngine, MappingEngine>();
container.RegisterMvcControllers(Assembly.GetExecutingAssembly());
DependencyResolver.SetResolver(
new SimpleInjectorDependencyResolver(container));
}
我收到了一个错误:
要使容器能够创建MappingEngine,它应该只包含一个公共构造函数,但它有2个。
参数名称:TImplementation。
我做错了什么?
答案 0 :(得分:3)
Simple Injector不能自动为您自动连接MappingEngine
类型,它不应该,因为这是一个框架类型,框架类型不应该自动连接,因为你可以阅读here。
相反,请使用手动接线,如下所示:
var container = new Container();
container.RegisterSingle<IMappingEngine>(Mapper.Engine);
