How to add Dapper to existing porject #2745

oshabani created 3 years ago

we were adding Dapper to our project using this article https://docs.abp.io/en/abp/latest/Dapper

but we face the issue of DependencyResolutionException None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'Sbg.ProjectControl.Locations.LocationsAppService' can be invoked with the available services and parameters: Cannot resolve parameter 0

ABP Framework version: v5.1

UI type: MVC
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): yes
Exception message and stack trace:DependencyResolutionException: None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'Sbg.ProjectControl.Locations.LocationsAppService' can be invoked with the available services and parameters: Cannot resolve parameter 'Sbg.ProjectControl.Locations.ILocationDapperRepository locationDapperRepository' of constructor 'Void .ctor(Sbg.ProjectControl.Locations.ILocationRepository, Volo.Abp.Domain.Repositories.IRepository`2[Sbg.ProjectControl.SubProjects.SubProject,System.Int32], Sbg.ProjectControl.Locations.ILocationDapperRepository)'.
Steps to reproduce the issue:
- Add Volo.Abp.Dapper package to the EntityFramewokCore solution
- Create a Module class for Dapper :
  - namespace Sbg.ProjectControl.EntityFrameworkCore { [DependsOn(typeof(AbpDapperModule))] public class ProjectControlDapperModule:AbpModule { }
- create a Dapper repository interface public interface ILocationDapperRepository:IRepository<Location,int>
- create Dapper repository implement the interface public class DapperLocationRepository : DapperRepository<ProjectControlDbContext>, ITransientDependency, ILocationDapperRepository
- in the Application service private readonly ILocationDapperRepository _locationDapperRepository;
- in the constructor i added a parameter to inject the repository
  - public LocationsAppService(ILocationRepository locationRepository, IRepository<SubProject, int> subProjectRepository, ILocationDapperRepository locationDapperRepository)
that is!
we need to know how to fix this issue

Hi, you don't need to inherit your repository class from the IRepository<TEntity, TKey> interface. If you remove it, you don't get the DependencyResolutionException.

Did you add DependsOn[typeof(ProjectControlDapperModule)] to your web module class as below:

//other depends on statements...
[DependsOn(typeof(ProjectControlDapperModule))]
public class MyWebModule : AbpModule 
{
    //...
}
