功能说明
基于javaweb的JSP+Servlet毕业生离校管理系统(java+jsp+servlet+jquery+mysql)
需求分析
使用JSP+Servlet+Mysql技术设计一个毕业生离校管理系统, 整个系统采用BS架构, 为高校方便进行毕业生离校流程进行统一的离校流程, 极大的减少了大量学生同时离校的过程中杂乱的情况, 整个系统分为学生, 教务处, 辅导员, 图书馆, 宿管, 财务处, 系办公室, 管理员登等角色, 不同的角色拥有不同的功能
实现功能
该项目是一个基于JSP+Servlet+Mysql实现的毕业生离校管理系统, 用于统一离校流程, 提升学校管理效率,主要分为如下模块 系统的登录注册模块, 注意只能注册学生账号 学生角色: 可以查看未归还图书信息, 未归还宿舍信息, 欠费信息, 手动发起离线申请 教务处角色: 可以添加离校信息 并确认某人离校 辅导员角色: 辅导员可以登录系统查看离校本人并进行确认离校。 图书馆人员角色: 登录系统添加未归还的图书信息。 宿管处角色: 添加未归还钥匙信息并确认离校状态 财务处角色: 添加欠费信息并确认离校状态
运行环境
jdk1.8,tomcat8.5,mysql5.7,Eclispse/IDEA/MyEclipse
项目技术
jsp, servlet, jquery
技术原理
项目是一个基于JSP+Mysql实现的毕业生离校管理系统, 采用比较传统的javaweb模式进行开发, 除了使用dwr并没有使用任何其他大型框架, 但是本项目的servlet+jsp也是构造了一个符合mvc设计模式及的封装代码, 另外此项目自带一篇毕业论文, 项目可以直接用于毕业设计中
注意事项
系统采用jsp+servlet+mysql编写, eclipse导入项目的时候properties的编码需要调整为utf8 mysql的编码utf8, 需要在dbinfo.properties中修改数据连接与密码
使用说明
- 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件； 2. 将项目中dbinfo.properties配置文件中的数据库配置改为自己的配置 3. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven; 若为maven项目，导入成功后请执行maven clean;maven install命令，配置tomcat，然后运行； 4. 运行项目，输入localhost:8080/xxx 登录
