【摘要】 目前，越来越多的用户选择使用J2EE架构企业级应用．这是因为J2EE是一种以JAVA语言为基础的标准体系结构定义，是使用Java技术开发企业级应用的一种工业标准。它克服了传统Client／Server模式的弊端并适应了Browser／Server架构的潮流。为应用Java技术开发服务器端应用，J2EE提供了一个平台独立的、可移植的、多用户的、安全的和基于标准的企业级平台，从而简化了企业应用的开发、管理和部署。 当前，全国公安交通管理的信息化建设发展迅速。现有交警信息系统已经不能满足日益增长的业务发展与数据量的要求。因此，依照J2EE／EJB技术规范，建设一套公安交警信息应用服务系统，深度开发和充分利用公安信息资源，显得尤为必要。 在对J2EE的体系结构以及EJB技术规范作了详细的分析研究基础上，本文完成了对公安交警信息应用服务系统(违章管理子系统)的系统设计及代码的编写(包括系统架构设计，数据结构设计，应用模型设计，业务功能设计)，并针对EJB技术在系统中的应用进行了深入的分析、研究。对于实现EJB应用的开发细节(包括会话Bean、实体Bean和消息驱动Bean)作了重点论述。探讨了事务的使用以及研究了如何选择最佳的数据持久化技术(包括在会话Bean和实体Bean之间或者BMP和CMP之间做出最佳选择)。更多还原

【Abstract】 At present, more and more users choose to use J2EE to build up enterprise-class application. This is because J2EE is a kind of standard system structure definiens based on Java. It is a kind of industrial standards of enterprise-class application development of Java technology, overcomes the drawbacks of traditional client/server mode, and has suited for Browser/Server framework. It has provided a platform-independent, portable, multi-user, secure and standard enterprise-class platform for development of the server using Java. Thus, it simplifies the development, management and deployment for enterprise-class application.Today, the information-based construction of national public security traffic management develops rapidly. The existing traffic police information system has not satisfied the request for the increase in business development and data quantity day by day. It is particularly necessary to build a Public Security Traffic-Police Information Application System based on J2EE/EJB Technology, which is used for deep development and full utility of the public security information resources.In this article, the system design and the code compilation (including systematic framework design, data structural design,application model design, business function design) of the public security traffic-police information application system (violation management subsystem) have been completed. They base on the detailed analysis and research of system structure of J2EE and EJB technical specification. The deep research and analysis of the application in this system of EJB technology have been made. The development details for implementing the EJB application (including use of the session beans, entity beans and message-driven beans) have emphatically been described. The article also discusses how to use transactions, and choose the best persistence technology (including how to make the best choice between session beans and entity beans or between BMP and CMP).更多还原
