我在最近的项目中使用CQRS模式，所以我定义了一些我称之为Commands和CommandParameter的{{1}}。
对于CommandHandlers我有CommandParameters个es和Class s：
Interface对于public interface ICommandParameter
{
}
public abstract class BaseEntityCommandParameter<T> : IAggregateRoot,ICommandParameter
where T : ModelEntitySuperType, new()
{
public T Entity { get; set; }
protected BaseEntityCommandParameter()
{
Entity = new T();
}
}
public class InsertCommandParameter<T> : BaseEntityCommandParameter<T>
where T : class, new()
{
}
我定义了这些CommandHandlers es和Class s：
Interface我使用它们为每个public interface ICommandHandler<TCommandParameter>
where TCommandParameter :ICommandParameter
{
void Handle(TCommandParameter parameter);
string CommandCode { get; }
}
public class InsertCommandHandler<TCommandParameter, TEntity>
: ICommandHandler<TCommandParameter>
where TCommandParameter : BaseEntityCommandParameter<TEntity>, new()
where TEntity : ModelEntitySuperType, IAggregateRoot, new()
制作适当的CommandParameter和CommandHandler，例如我Entity：
Order我想自动使用public class OrderInsertCommandParameter:InsertCommandParameter<Order>
{
}
public class OrderInsertCommandHandler
: InsertCommandHandler<OrderInsertCommandParameter, Order>
{
private readonly IUnitOfWorkFactory _factory;
public OrderInsertCommandHandler(IUnitOfWorkFactory factory,
IRepository<Order> repository)
: base(repository)
{
_factory = factory;
}
public override void Handle(OrderInsertCommandParameter parameter)
{
var uow = _factory.Create();
parameter.Entity.OrderCreationTime = DateTime.Now;
base.Handle(parameter);
uow.Commit();
}
}
注册这些CommandParameter和相应的CommandHandler，如何定义自定义转换来执行此操作？
答案 0 :(得分：0)
以下应该可以解决问题：
container.Configure(r =>
{
r.Scan(s =>
{
s.Assembly(typeof(ICommandHandler<>).Assembly);
s.ConnectImplementationsToTypesClosing(typeof(ICommandHandler<>));
});
});
