使用structuremap解决对存储库接口MVC5的依赖性

Question

I have a mapper that takes data from a repository project. I have a IMenueMapper interface that is passed into the homecontroller like this:

public HomeController(IMenueMapper menueMapper)
{
    _menueMapper = menueMapper;
}

but the menuemapper class itself use the IMenueMapperRepository , and this come from another project and is passed in via dll

public MenueMapper(IMenueItemsRepository menueItems)
{
    _menueItems = menueItems;
}

While I can easily resolve the IMenuemapper in the MVC project, using structuremap.mvc5, I can't resolve the repository. Is there a way of achieving the DI in this instance?

Answer 1

You need to register the abstraction (repository interface and implementation) in the composition root.

You indicated that the IMenueMapper is registered via;

scan.AssemblyContainingType<MenueMapper>();

Since

but the MenueMapper class itself use the IMenueMapperRepository , and this come from another project and is passed in via dll

Then it should also be scanned as it belongs to another assembly

scan.AssemblyContainingType<MenueItemsRepository>();

Make sure that the project references the assembly in question
