2、计提出了重大的挑战。由于传统的报表系统主要采用 C/S结构的报表设计器，具有一定的局限性，并且报表的开发是根据用户的需求定制的，报表处理部分与其它的业务逻辑关联度较大，导致了报表模块与系统的高度耦合性，可重用性差，对报表及其相关应用的开发和维护需要花费大量的时间和精力，难以适应开发过程的多样性和变化性，因此，传统意义上的报表设计模式已经很难满足日益增长的 Web 报表开发的需求。本文研究的通用报表系统，应用了Java开源报表引擎JasperReports与可视化工具iReport，将报表模板和报表数据分离开，用户既能根据自己的需要设计报表模板，又能按照业务需求自主地选择数据来源，并运用Jasp
3、erReports强大的报表功能和丰富的可扩展接口，实现了报表的定制。论文首先介绍了报表系统的发展现状及本课题的研究意义，通过介绍国内外几种比较流行的报表制作工具，分析了当前报表工具应用中存在的一些问题。针对报表系统解决方案存在的问题，本文所设计的基于J2EE体系架构的通用报表系统，使用了MVC设计模式，将控制逻辑、业务逻辑和视图展现三者分开，根据此设计体系，把通用报表系统分为控制层模块、业务逻辑模块、通用报表模块以及视图模块四个模块。通用报表模块，实现了报表处理部分与其它业务逻辑之间的分离，即在业务逻辑模块中，不需要进行报表数据和模板的整合,而是直接将数据和报表模板转到通用报表模块中处理,将
4、报表功能作为一个单独的模块来设计，简化了编程工作，提高了系统的通用性、可复用性和可维护性。关键词：通用报表JasperReportsiReportJ2EE MVC 设计模式I成都理工大学硕士学位论文Based on J2EEGeneral ReportingSystemResearchandImplementationIntroduction of the author: Guanxin, female, was born in October, 1984, whosetutor was Professor HuangDilong.She graduated from Chengdu Univ
