java学生教师管理系统(代码版)

java学生教师管理系统

- 在项目下创建的包有(记得项目里导包和API):
- **controller包下内容**(客服业务)
- - - controlStudent类
    - controlTeacher类
- **dao包下内容**(库管业务)
- - - daoperson类
    - daoStudent类
    - daoTeacher类
- **domin包下内容**(定义成员变量)
- - - person类
    - Student类
    - Teacher类
- **service包下内容**(业务员业务)
- - - serviceStudent类
    - serviceTeacher类
- **entry包**(里面是主方法main--运行类)
- - - infomanagerentry类
- 实现效果

这个是java版本的代码版本,已在控制台上完美运行,用的编写软件是idea.希望大家可以参考和交流,我也会慢慢把更完善注释和优化版本发布出来.管理系统里管理了学生和教师,可以根据个人需要只管理一个或者交流发出来
