使用Ninject将单个工厂实例注入多个存储库和工作单元可以通过以下步骤实现:
public interface IFactory
{
IRepository<T> GetRepository<T>();
IUnitOfWork GetUnitOfWork();
}
public class Factory : IFactory
{
private readonly IRepository<SomeEntity> _repository1;
private readonly IRepository<AnotherEntity> _repository2;
private readonly IUnitOfWork _unitOfWork;
public Factory(IRepository<SomeEntity> repository1, IRepository<AnotherEntity> repository2, IUnitOfWork unitOfWork)
{
_repository1 = repository1;
_repository2 = repository2;
_unitOfWork = unitOfWork;
}
public IRepository<T> GetRepository<T>()
{
if (typeof(T) == typeof(SomeEntity))
{
return (IRepository<T>)_repository1;
}
else if (typeof(T) == typeof(AnotherEntity))
{
return (IRepository<T>)_repository2;
}
else
{
throw new NotSupportedException($"Repository for type {typeof(T).Name} is not supported.");
}
}
public IUnitOfWork GetUnitOfWork()
{
return _unitOfWork;
}
}
Bind
方法将工厂接口绑定到具体的工厂类,并设置为单例模式。同时,使用ToMethod
方法指定工厂类的实例化方式。例如:var kernel = new StandardKernel();
kernel.Bind<IFactory>().To<Factory>().InSingletonScope().WithConstructorArgument("repository1", new Repository<SomeEntity>())
.WithConstructorArgument("repository2", new Repository<AnotherEntity>())
.WithConstructorArgument("unitOfWork", new UnitOfWork());
public class SomeService
{
private readonly IFactory _factory;
public SomeService(IFactory factory)
{
_factory = factory;
}
public void DoSomething()
{
var repository1 = _factory.GetRepository<SomeEntity>();
var repository2 = _factory.GetRepository<AnotherEntity>();
var unitOfWork = _factory.GetUnitOfWork();
// 使用存储库和工作单元进行操作
}
}
通过以上步骤,就可以使用Ninject将单个工厂实例注入多个存储库和工作单元。这样可以实现依赖注入,提高代码的可测试性和可维护性。
