为什么我们需要抽象工厂设计模式？ [英] Why do we need Abstract factory design pattern?

问题描述

大多数定义说：

一个抽象工厂提供一个
接口，用于创建
相关的家庭对象没有指定
他们的具体类

An abstract factory provides an interface for creating families of related objects without specifying their concrete classes

使用抽象工厂模式是什么，我们可以通过创建对象来实现任务具体类本身。为什么我们有一个创建Concrete类的对象的工厂方法？

What is the use of Abstract Factory Pattern as we can achieve the task via creating object of concrete class itself. Why do we have a factory method that creates object of Concrete class?

请提供我任何现实生活中的示例，我必须实现abstractFactory模式？

Please provide me any real life example where I must implement abstractFactory pattern?

推荐答案

抽象工厂是依赖注入（DI）的非常中心的设计模式。以下是抽象工厂应用被接受作为解决方案的Stack Overflow问题列表。

Abstract Factory is a very central design pattern for Dependency Injection (DI). Here's a list of Stack Overflow questions where application of Abstract Factory has been accepted as the solution.

根据我的理解，这些问题代表了人们的真正关切或问题，所以应该让你开始一些现实生活的例子：

To the best of my understanding, these questions represent real concerns or problems that people had, so that should get you started with some real-life examples:

• 是否有用于初始化通过a创建的对象的模式DI容器


• 不能组合工厂/ DI


• WCF依赖注入和抽象工厂


• 当关键类需要Session（或其他特定于上下文的变量）时，如何设置IoC


• 如何根据最终用户配置值来解析类型？


• 使用Unity的策略模式和依赖注入


• IoC顶部的抽象工厂模式


• 这是使用和测试类的正确方法使用工厂模式？


• 
  
• DI容器，工厂或临时对象的新用户？


• 如何单元测试实例创建？


• 用户输入依赖注入的最佳策略是什么？

• Is there a pattern for initializing objects created via a DI container
• Can't combine Factory / DI
• WCF Dependency injection and abstract factory
• How to set up IoC when a key class needs Session (or other context-specific variable)
• How to Resolve type based on end-user configuration value?
• Strategy Pattern and Dependency Injection using Unity
• Abstract factory pattern on top of IoC?
• Is this the correct way to use and test a class that makes use of the factory pattern?
• DDD Book, Eric Evans: Please explain what is meant by "The FACTORY should be abstracted to the type desired rather than the concrete class(es) created."
• DI container, factory, or new for ephemeral objects?
• How to unit test instance creation?
• What is the best strategy for Dependency Injection of User Input?
