推荐答案

答案：依赖注入







依赖注入（DI），也称为控制反转（IoC），可以用作一种鼓励这种松散耦合的技术。实现DI有两种主要方法：构造函数注入和setter注入。显然，在某些时候，某些东西必须负责创建将被注入另一个对象的具体对象。注入器可以是父对象，我称之为DI控制器，或者可以外部化并由DI容器框架处理。

Answer:Dependency Injection



Dependency Injection (DI), also more cryptically known as "Inversion of Control" (IoC), can be used as a technique for encouraging this loose coupling. There are two primary approaches to implementing DI: constructor injection and setter injection. Obviously, at some point, something must be responsible for creating the concrete objects that will be injected into another object. The injector can be a parent object, which I'll call the "DI controller", or can be externalized and handled by a "DI container" framework.
