摘要
在面向对象程序设计中,应用设计模式对于构建能够提高复用性、增强灵活性与可维护性的程序结构具有至关重要的作用。以策略模式与模板方法模式相结合在电商系统中促销活动的应用为例,具体介绍策略模式与模板方法模式相结合的UML类图,以及在特定场景下的应用。同时,阐述了运用设计模式带来的软件扩充和复用的方便性,以此丰富设计模式的应用案例。实验结果表明,两种设计模式的结合能够增加代码的可复用性,符合“对扩展开放,对修改关闭”的设计原则,使系统更容易扩展。
In object-oriented programming,application design patterns play an important role in building a program structure that can improve reusability,enhance flexibility and maintainability.Taking the application of the combination of strategy model and template method model in the promotion activities of e-commerce system as an example,the UML class diagram of the combination of strategy model and template method model and its application in specific scenarios are introduced in detail.At the same time,it expounds the convenience of software expansion and reuse brought by design patterns,so as to enrich the application cases of design patterns.The experimental results show that the combination of the two design patterns can increase the reusability of the code,which is in line with the design principle of“open to extension,close to modification”and makes the system easier to expand.
