基于轻量级Java EE框架的高校招投标管理系统

Bidding Management System in Colleges and Universities Based on Lightweight Java EE Framework

针对高校人工管理招投标过程的缺陷和不足,使用轻量级的Java EE框架Struts2、Spring和Hibernate实现了一个松耦合的网上招投标管理系统,系统采用Java EE的分层架构"表现层-中间层(Web层+Service层+DAO层+PO层)–数据层",层与层之间通过接口联系,模块与模块之间遵循"高内聚低耦合"的原则,系统具有很好的复用性、扩展性和可维护性,实现了网上招标、投标、评标、落标等功能,可以使高校采购管理走向规范化、集约化,提升管理水平。

In view of the defects in the bidding process in colleges and universities,the Struts2,Spring and Hibernate of the lightweight Java EE framework was adopted to achieve a loosely coupled internet bidding management system,in which Java EE layered architecture ＂presentation layer-intermediate layer（Web layer ＋ Service layer ＋ DAO layer ＋ PO layer）-data layer＂ was used.The layers were contacted by interface,and the ＂low coupling＂ principle was applied between modules.The system has good reusability,extensibility and maintainability.It realizes online bidding,tender and other functions,improving procurement management in colleges and universities.
