摘要
伴随计算机网络技术的飞速发展,电子商务日益成为商业交易的主要方式,图书电子商务系统是其中极为典型的应用领域。针对传统Web开发中出现的业务逻辑和页面逻辑混杂,重用业务逻辑困难以及流程难以维护的弊端,文中介绍了最新的J2EE技术的原理、优势和常用的设计模式,旨在遵循J2EE架构规范,采用前端控制器模式和门面设计模式对系统进行总体设计,解决上述问题。并给出了该系统的部分实现代码。按照这种方式开发的系统的确有效地提高了代码的可重用性和可扩展性,并且大大缩短了研发周期,有很高的实用价值。
With the rapid development of Internet, E-business becomes the main trade method. The E-book-business system is the typical application field. Aiming at the shortage in traditional modes, such as immingling of page logic and business logic, difficulty in reusing the business logic model and difficulty in maintaining the work flow, this paper presents the principles, predominance and common design pattern of the J2EE technology, designs the system with front controller mode and facade mode. The implementation based on J2EE framework is given. This method effectively improves the reusability and extensibility of code, abridges the developing time and possesses high practical value.
