依赖注入和控制反转 [英] Dependency Injection and inversion of control

问题描述

依赖关系的具体实现是什么意思？

what does " concrete implementations of the dependencies" means?

推荐答案

依赖的具体实现意味着针对具体类而不是接口进行编程。所以依赖类更加紧密耦合。所以应该考虑使用接口来避免这种耦合。

希望这会有所帮助......

A concrete implementation of dependency means programming against a concrete class instead of interface. So the dependency classes are more tightly coupled. So should consider use interface to avoid this coupling.
