摘 要
基于 Web 高校就业管理系统平台的设计与开发
国内各大专院校办学规模及毕业生数量在国内教育事业取得长足性发展的基础上
得到了持续拓展和增长,这一现象的出现就给高校就业工作所涵盖的规则性与实效性在
一定程度上提出了更深一层的要求和标准。现如今,高校就业管理机构急需解决的问题
就是,怎样将在毕业生就业的信息化程度提高,使得毕业生和用人单位之间能更好的合
作,同时满足彼此间的需求,进而促使用人单位的招聘率以及学生的就业率有所提高。
本课题基于在介绍和阐述就业管理背景及意义的基础上,对现阶段毕业生就业管理
所具备的各种特点及特性进行了详细的介绍,同时针对就业指导中心毕业生就业管理招
聘之需求采取了系统的分析方式,设计的同时完成了就业管理信息系统工作。就业管理
信息系统引用现阶段广为流行的Web技术为系统的总体架构,同时将WEB四层架构和MVC
设计模式结合起来,致使业务逻辑和表现逻辑相分离得以实现,简洁了该系统在开发和
维护方面的工作;将开放源码中的Jboss引用为应用服务器,而Web服务器引用整合的
Tomcat;用JSP主要来完成页面表现工作,实现系统和用户的交互事宜;主要采用EJB组
件来封装实现业务逻辑处理工作。
本课题研究中,系统用户有学生、管理员与企业代表三种,每一个用户可以通过自
己的访问入口进入到系统当中,以实现权限范围之内的功能操作事项。系统着重完成并
实现了招聘管理、就业指导管理和系统管理系统,同时在该管理系统中渗入了毕业生管
理、签约管理、单位管理、招聘信息管理、数据统计上报、生源核对、就业信息统计、
系统配置、权限管理等诸多功能模块信息。
本研究课题就从需求建模、组件开发、从数据的访问至系统的配置以及详细设计等
方面就系统的研发和实现过程进行了详细的阐述和讨论。系统在一定程度上完成并实现
了毕业生在就业方面的整体性管理工作,系统的成功性运用会给用人单位招聘与毕业生
就业提供简洁而快捷的服务信息,进而大大的提高了就业指导的工作效率。

Abstract
Design and Implementation of College Employment Management Platform Based on Web
There has been the enlargement of the school scale and the number of graduates has been
increasing, which is based on the great development of the domestic education course. The
phenomenon puts forwards further demands and standard for the rules and actual:effects in
college graduates employment. Nowadays the question urgently needing to be solved in the
college employment management is that how to upgrade the informational degrees in
graduate employment and make better cooperation between graduates and units, and at the
same time meet each other’s demand and finally increase the employment rate of both the
units and the graduates.
The paper, based the introducing and explaining the background and meaning of the
college employment, in detail introduces all kinds of features and characteristics of graduate
employment in current stage, and in the meanwhile adopts the analytical pattern to meet the
demands of graduate employment in the employment direction center. The employment
management information system adopts the most popular web technique as the general
structure of the system, and combines the four-level web structure and MVC design mode,
thus realizes the separation of the business logic and appearance logic, and simplifies the
developing and maintenance work. It puts Jboss quotation of open code in the applied server,
while it uses integrated Tomcat in the web server. It uses JSP to make the web, to realize the
system and the interaction of the users, and uses EJB combination to seal and do the logic
processing.
In the study, there are 3 kinds of users, students, administrator and enterprise
representatives, each of them can log into the system through their own entrance, and realize
the functions in their range. The system puts emphasis on the employment management,
employment direction management and system management, and at the same time this
management system also includes several modules such as graduate administration, contract
administration, unit administration, employment information administration, statistics reports,
student hometown check, employment information statistics, system set and management
limits.
The study, in detail, explains and discusses the developing and realizing process from the
viewpoints of demanding module, parts developing, data visiting and system sets and detailed
design. The system, in some degrees, finishes and implemented the general administrative
work in the employment of graduates. It successfully operates the simple and quick service
system of units and students employment and thus greatly increases the efficiency of
employment direction.
