J2EE架构的模板化设计与实现

Template Designation and Implementation of the J2EE Architecture

摘要:

在传统轻量级J2EE分层架构的基础上，利用泛型与反射技术在业务层和数据访问层设计模版化的操作模块，可以为其具体领域对象模块提供公共操作逻辑。本文提出模版化构架方式，不仅避免了每个领域模块相似逻辑的重复编写，提高开发效率，而且统一的操作策略增强了应用的健壮性、可维护性、能灵活应对需求的总体变动。模版化构架方式，对改进与完善基于开源框架的J2EE架构进行了一定的探索，应用此种架构对业务逻辑相对单一简单的应用开发具有一定的指导意义。

Abstract: On the basis of the lightweight layered architecture of the traditional J2EE, a template of the operating module is designed by using generic and reflection in the business and data access layer, providing a common operation logic to the module of specific domain object. Through this template designation, it not only can avoid the repeated writing the similar logic of each domain module, but also is conducive to the robustness, maintainability of the system, and flexibility to the changes of whole business needs. Template structure can improve and perfect the traditional J2EE architecture based on the open source framework. Utilizing the architecture in the application whose business logic is relatively simple and single has some guiding significance to the J2EE development.
