带有结构图的Sharp存储库自定义存储库

Question

Using StructureMap 3.0.3.116 to initialize services with custom IRepository<,> with SharpRepository, structuremap still cannot find concrete class using the default convention.

public interface IBlogImageRepository : IRepository<BlogImage,int>
{
}

public class BlogImageRepository : 
    ConfigurationBasedRepository<BlogImage, int>, IBlogImageRepository
{

Error:

No default Instance is registered and cannot be automatically determined for type 'My.Assembly.Repositories.IBlogImageRepository'

    ObjectFactory.Initialize(x =>
    {
        x.Scan(scan =>
        {
            scan.Assembly("S3.Libs");
            scan.IncludeNamespace("S3.Libs.Repositories");
            scan.IncludeNamespace("S3.Libs.Services");
            scan.WithDefaultConventions();
            scan.ConnectImplementationsToTypesClosing(typeof (IRepository<,>));
        });
        x.Scan(scan =>
        {
            scan.TheCallingAssembly();
            scan.WithDefaultConventions();
        });
    });

Answer 1

Looks like I got it to work by adding [DefaultConstructor] attribute to the constructor that had no parameters. It was trying to use the greediest constructor.

Answer 2

It might be that it is actually throwing the exception when trying to create the IRepository<,> within the IBlogImagerepository as opposed to not being able to find the IBlogImageRepository interface itself. The inner exception might give more details.

I would try using the SharpRepository.Ioc.StructureMap NuGet package and then adding

x.ForRepositoriesUseSharpRepository();

to your initialization method and seeing if this helps.
