java后台流程以及命名规范

先封装字段，然后写dao层，service接口，service服务，dao.xml，最后controller

1,、界面层（输入数据，查看结果）view                                                                 显示界面

2、业务层 business | biz | blc | manager | service                                                 算法，判断

3、数据层  dal | dao                                                                                                     数据存取

4、实体层  entity | moda | bean | domain                                                                 封装数据

//查询全部

public List<UserInfo> selectall();

//修改

public int update(UserInfo userInfo);

//删除

public int delete(UserInfo userInfo);

}

User
