基于FlexPaper的校内公示系统设计与实现

Design and Implementation of a University-Wide Document Sharing System Based on FlexPaper Technique

摘要: 大连理工大学每年有大量的公示材料，涉及到职称评审、升职考核、竞聘材料等等，有些公示材料只能查看不允许下载，或者需要对公示材料设置查看和下载的权限。设计与实现符合大连理工大学需要的校内公示系统，既要保证教师公示材料的安全可靠，同时又要满足公示材料全校范围内的分享阅读。校内公示系统基于FlexPaper技术设计实现方案，将office文件等转换成pdf文件，再将pdf文件转换为swf文件，在校内门户页面使用FlexPaper插件播放公示文件，该技术方案成熟可靠并被广泛使用。系统架构设计采用业界领先的基于领域驱动的开发方式，分为表现层、系统应用层、应用支撑层、数据资源层及基础平台层，业务逻辑集中在领域层，系统采用我校统一的信息安全体系和标准规范，使系统具有高可用性、高可靠性及高性能。

Abstract: Every year, Dalian University of Technology produces a huge amount of publicity material related to human resource management work, such as the professional title evaluation, promotion evaluation, competitive selection etc. Some of these publicity documents are restricted to read only, and no downloading is allowed, or different reading/downloading permissions are set to different documents. Considering designing a document sharing system corresponded with the actual needs of the university, it is important to guarantee both the security and the school-wide sharing me-chanism of the publicity documents. Document Sharing System is based on the FlexPaper technical proposal. After converting Microsoft office files to pdf files, swf tools can be used to change pdf files to swf files, then these documents can be loaded on the university portal website using FlexPaper plugin which is reliable and widely used by many companies. The system architecture, based on the industry-leading Domain Driven Design approach, is divided into presentation layer, system appli-cation layer, application support layer, data source layer and basic platform layer. Business logic is concentrated in the domain layer and the cluster-based load balancing and cache make the system with high availability, high reliability and high performance.
