我正在尝试在 ASP.NET MVC5 项目中使用 Autofac 实现依赖注入。但我每次都收到以下错误:
在“MyProjectName.DAL.Repository”类型上找不到使用“Autofac.Core.Activators.Reflection.DefaultConstructorFinder”的构造函数......
我在 App_Start 文件夹中的 Autofac 配置代码如下:
public static class IocConfigurator
{
public static void ConfigureDependencyInjection()
{
var builder = new ContainerBuilder();
builder.RegisterControllers(typeof(MvcApplication).Assembly);
builder.RegisterType<Repository<Student>>().As<IRepository<Student>>();
IContainer container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
}
}
在 Global.asax 文件中:
public class MvcApplication : HttpApplication
{
protected void Application_Start()
{
// Other MVC setup
IocConfigurator.ConfigureDependencyInjection();
}
}
这是我的 IRepository:
public interface IRepository<TEntity> where TEntity: class
{
IQueryable<TEntity> GelAllEntities();
TEntity GetById(object id);
void InsertEntity(TEntity entity);
void UpdateEntity(TEntity entity);
void DeleteEntity(object id);
void Save();
void Dispose();
}
这是我的存储库:
public class Repository<TEntity> : IRepository<TEntity>, IDisposable where TEntity : class
{
internal SchoolContext context;
internal DbSet<TEntity> dbSet;
public Repository(SchoolContext dbContext)
{
context = dbContext;
dbSet = context.Set<TEntity>();
}
.....................
}
这是我的学生控制器:
public class StudentController : Controller
{
private readonly IRepository<Student> _studentRepository;
public StudentController()
{
}
public StudentController(IRepository<Student> studentRepository)
{
this._studentRepository = studentRepository;
}
....................
}
我的 Autofac 配置有什么问题..请帮忙?
