类图-从类到接口的依赖关系或关联关系？ [英] Class diagram - dependency or association from class to interface?

问题描述

我有一个关于在使用依赖注入的情况下创建类图的问题。

I have a question regarding creating a class diagram where I have used dependency injection.

我有以下代码示例：

public class ReservationController : ApiController
{
    private readonly IGetReservationService _getReservationService;

    public ReservationController(IGetReservationService getReservationService)
    {
        _getReservationService = getReservationService;
    }

    // GET list of all reservations
    public List<ReservationViewModel> GetReservations()
    {
        return _getReservationService.GetReservations();
    } 

    // GET single reservation by id
    public List<ReservationViewModel> GetReservation(string reservationNumber)
    {
        return _getReservationService.GetReservation(reservationNumber);
    }

}

在这里，您看到控制器（ ReservationController）将IGetReservationService注入构造函数中。在控制器和接口之间创建关系时，您是使用依赖关系还是关联关系？

Here you see that the controller (ReservationController) getting the IGetReservationService injected in the constructor. When creating the relationship between the controller and the interface, do you then use a dependency or an association?

我的猜测是它应该是依赖关系，因为我们正在使用依赖关系注射？

My guess is that it should be a dependency since we are using dependency injection?

美好的一天。

推荐答案

是的，这是一个依赖项。如果您有对象引用（例如，用于属性），则使用关联。

Yes, this is a dependency. An association is used if you have object references (e.g. for a property).
