J2EE软件架构浅析

J2EE Software Architecture Analysis

为了解决单纯的00不能很好的解决所有系统设计的问题,J2EE提出提供了一整套标准化的模块,可以自动处理大部分的应用程序的细节,而不需要复杂的编程,基于服务组件,从而简化了企业应用开发的复杂性。该文首先考察企业的应用和需求的一般概念,然后简要介绍了J2EE的基本知识,并结合软件工程的思想,讨论多层J2EE应用程序体系结构,分析他们的优点,以满足企业级应用。验证了将应用程序中的商业逻辑同对其提供支持的通用服务进行分离等设计思想的可行性。

In order to solve this problem that pure 00 could not solve all the problems in the system design,based on service-oriented com ponents,the J2EE provides a set of standardized module and simplifies enterprise applications by handling many details of application behav ior automatically without complex programming.This paper firstly reviews the general concept and the requirement of enterprise applica tion,then the basic knowledge of J2EE is introduced.In the light of the software engineering thoughts,this paper combines the idea of Software-Engineering to discuss the framework of multi-tier J2EE,and meanwhile analyzes their advantages to explore how they can satis fy the demand of enterprise applications.At last,this paper shows the feasibility of design concept was verified in which the business logic in application program and the supportive general service were separated.
