依赖注入与工厂模式 [英] Dependency Injection vs Factory Pattern

问题描述

大多数引用依赖注入使用的例子，我们也可以解决使用工厂模式。看起来就像使用/设计依赖注入和工厂之间的区别是模糊的或薄的。

Most of the examples quoted for usage of Dependency Injection, we can solve using the factory pattern as well. Looks like when it comes to usage/design the difference between dependency injection and factory is blurred or thin.

有人告诉我，它如何使用它有所不同！

Once someone told me that its how you use it that makes a difference!

我曾经使用 StructureMap 一个DI容器解决一个问题，后来我重新设计了一个简单的工厂工作，并删除了对StructureMap的引用。

I once used StructureMap a DI container to solve a problem, later on I redesigned it to work with a simple factory and removed references to StructureMap.

任何人都可以告诉我们它们之间有什么区别使用什么，这里最好的做法是什么？

Can anyone tell me what is the difference between them and where to use what, whats the best practice here?

推荐答案

使用工厂时，您的代码仍然负责创建对象。通过DI，您将该责任外包给另一个类别或框架，这与您的代码是分开的。

When using a factory your code is still actually responsible for creating objects. By DI you outsource that responsibility to another class or a framework, which is separate from your code.
