：Java课程设计 学生学籍管理系统 要求eclipse运行
其实也就是数据库的增删改查

首先建两张表 一个是用户表 一个是学生表
根据表的字段在entity包下建两个实体类 两张表对应两个实体类
如果使用mybatis的话可以在dao包下写接口
增 改 传实体类对象 删 和 按ID查询 传int 查全部不用传参数 条件查询最好传Map
然后在service包下定义所有需要用到的接口 在建个子包里面去实现接口 在controllor层就用接口new实现类
上面的代码会有冗余的部分 可以把那部分封装成一个utils
不同的view层用不同的controllor 至此Model层就写完了
如果view层是jsp的话 controllor可以用struts2 jsp请求到struts2的action action根据不同的请求调用不同的service 再由service调用dao操作数据库；
这就是MVC
求完整java代码一份 学籍管理系统 。 不需要高大上的功能， 基本的增删改查登录注册退出什么的就好。
