公告数据合法性检验系统研究

摘要

Based on history data,through comprehensive statistics analysis of each parameter of notice data, combining deep research of business documents and communication of business specialist,got the legitimacy inspection rules of notice data. Based on these rules,established the structure of the legitimacy inspection software system. The system is made up of three part; the legitimacy inspection Jar package,the legitimacy inspection Web services,the legitimacy inspection software. The legitimacy inspection system adopted many design patterns. The legitimacy inspection Jar package adopted mainly decorator pattern and chain of responsibility pattern;Factory pattern, command pattern,adapter pattern,strategy pattern were used also. The legitimacy inspection Web services adopted mainly decorator pattern and command pattern. The legitimacy inspection tool software adopted mainly MVC pattern and adapter pattern etc. The full system adopted many Java opensource frameworks,such as Axis2, Log4j etc.%基于历史数据,通过对各参数字段取值情况进行综合统计分析,结合深入研究业务文档和与业务专家的深入沟通,确立公告技术参数的合法性检验规则体系.根据确立的合法性检验规则体系,综合考虑实际应用情况,通过系统性的分析、研究,确立了公告数据合法性检验系统的组成和整体结构.检验系统由校验Jar包、校验Web services、校验工具软件组成,其中校验Jar包是校验系统的核心和研究、开发、维护的重中之重.检验系统在设计实现过程中,综合采用了多种设计模式,确保了本系统具有较高的灵活性、可扩展性、可维护性.校验Jar包以装饰者模式、责任链模式为主,综合采用了工厂模式、命令模式、适配器模式、策略模式.校验Web services主要采用了适配器模式和命令模式.校验工具软件采用了MVC模式、适配器模式等多种设计模式.本系统在实现时,采用了Axis2开源Web service框架,使用Log4j来记录日志以解决责任链模式难以追踪调用过程的缺陷.
