1、孙延正管理信息系统开发实践设计方案成果报告山东建筑大学课 程 设 计 成 果 报 告题 目： 课 程： 院 （部）： 专 业： 班 级： 学生姓名： 学 号： 指导教师： 完成日期： 1. 系统功能简介本系统是毕业设计管理系统中教师、教研室主任用户的部分功能。系统向教师用户提供了查看已经提交的题目、提交题目并且可以进行修改和删除功能，向教研室主任提供了查询、审批的功能。使用eclipse-jee-europa-winter-win32 +Jdk1.6+Tomcat6开发、测试。2. 系统组件关系本系统使用构架进行开发，即使用JSP获得用户输入，由Servlet处理请求，将数据存入服务器对象（s

2、ession或request）中。JSP使用EL表达式和JSTL标签将数据从服务器对象中取出数据，展示出来。2.1. 登录功能的处理流程：login.jsp收集用户的输入，点击“提交”按钮后，由LoginServlet的doPost方法获得jsp页面的username、password参数的值，如果是合法用户，则将userInfo存入session并转向welcome.js页面，否则将”用户名或密码错误”以“error”为名存入session，转回login.jsp，该页面显示error的内容。2.2. welcome.jsp页面功能2.2.1. 查看所有设计题目2.2.1.1. 单击超链接“

3、查看所有设计题目”，即请求GraduateProjectServlet的doGet方法，由于没有其它参数，会直接执行该类的list方法。在list方法中，通过GraduateProjectDao获得所有的设计题目对象的集合，以“graduateProjects”为名存入request，然后请求被转发到listGraduateProject.jsp。在该页面中，通过JSTL的forEach标签遍历graduateProjects的每个题目对象，依次将它们的所有属性显示出来。如果某题目的指导教师与登录用户相同，且未被批准，则在后面列出“修改、删除”超链接。2.2.1.2. 单击“修改”链接，会请求

4、GraduateProjectServlet的doGet方法，同时将参数action=prepareEdit和id传入。doGet方法解析参数后，通过GraduateProjectDao获得参数id所代表的GraduateProject对象，以“prepareObjects”为名存入request，然后请求被送到editGraduateProject.jsp。在该页面中，通过JSTL的forEach标签遍历prepareObjects的每个题目对象，同时一次将他们的属性显示出来。然后老师根据自己的论文特点作相应的修改，最后有一个“提交”按钮，点击即可以实现对其的修改。2.2.1.3. 单击“删

5、除”链接，会请求GraduateProjectServlet的doGet方法，同时将参数action=delete和id传入。doGet方法解析参数后，由Integer重新定义并得到id，之后直接执行request的delete 操作，即删除对应项目的id。那么再次返回到listGraduateProject.jsp页面时，所删除的那个不会再次出现。因为其id已经被delete掉了。2.2.1.4. 单击“增加设计题目”链接(参见2.2.2)2.2.2. 增加设计题目 2.2.2.1. 浏览所有题 单击“提交题目”， 会请求GraduateProjectServlet的doPost方法，将参数

6、action=add和id传入。doPost方法解析参数，通过GraduateProjectDao获得id所对应的所有的题目对象的集合 。之后返回到addGraduateProject.jsp页面，通过JSTL的forEach标签遍历graduateProjects的所有对象，依次将其属性显示出来。之后用户就可以浏览所有的题目了。2.2.2.2. 审批题目审批是教研室主任特有的功能。单击“审批题目”时，会请求GraduateProjectServlet4DepartmentLeader的doPost方法。3. 源程序3.1. 实体类（省略方法），共XX个。1、Degree.javaackage
