The project was made in 2020-05-05~2020-05-10
谨以此片博文记录下我的第一个Java小Demo
代码请见GitHub
用户登录页
用户注册页
用户主页
用户购买健身卡(商城)页
管理员登录页
管理员主页
管理员添加用户页
管理员编辑用户页
细节1:常驻工具栏(内含搜索栏)
细节2:登录账号密码实时反馈(AJAX)
**细节3:翻页功能&可选每页显示条数 **
细节4:人性化的交互设计
JDK: 1.8
IDE: IDEA 201903
DataBase: MySQL 8.0
Mybatis: 3.5.2
POM: Maven
Tomcat 9
Bootstrap 3
JQuery 2
lombok 插件
分页插件: PageHelper 5.1.11
涉及技术 MySQL数据库,Spring,JavaWeb及MyBatis,简单的前端知识
大二没有好好学系统设计与分析,画的图一塌糊涂。
包含两个实体类,用户&管理员
生成该数据库的sql文件 在该GitHub跳转GitHub /sql 目录下
生成表如图示
应该叫做用例图吧,但我的好多符号都是错的,再次后悔没有好好学习!
设计该图的网址
其实这一步放在后面也合适,我为了让自己吃大饼,就先设计了一下。
项目文件结构如图所示
