In short, though both Factory pattern and DI helps object creation, DI is much better than Factory. With DI you get better decoupling of object and its dependency. Dependency injection also makes unit testing easier, which is very important to keep quality control in check. BTW, nothing comes...
这个时候更高级的工厂模式就站出来了,他不需要创建很多的工厂类就可以帮助我们创建各种实例,还可以管理对象的生命周期。这就是“DI容器(Dependency Injection Container)”,也可以叫做依赖注入容器。 其实标题上写的“Spring框架中的BeanFactory“就是一个牛逼哄哄的DI容器的核心接口。 Spring框架中的BeanFactory Spring的...
控制反转还有一个名字叫做依赖注入(Dependency Injection)。简称DI DIP = Dependence-Inversion Principle ( low-level module is depended on high-level module by defining abstract interface in high-level). Interface-Oriented Programming, not Implement-Oriented Programming Applicability Use the Factory Method pa...
The Factory Pattern is a creational design pattern that provides a way to encapsulate object creation. Instead of directly instantiating objects, you delegate the creation process to a factory class. This promotes loose coupling and makes your code more flexible and maintainable. Delegates in C# are...
Factory is flexible, and it doesn't tie you down to a specific dependency injection pattern or technique. SeeResolutionsfor more examples. Mocking If we go back and look at our original view model code one might wonder why we've gone to all of this trouble? Why not simply saylet myServi...
