一、语言和环境
1. 实现语言:Java语言
2. 环境要求:eclipse/myeclipse /idea、maven、mysql
3. 使用技术:Spring、SpringMVC、MyBatis、连接池和 json 包自行选择
二、实现功能
密室逃脱游戏越来越受年轻人的喜欢,现在将各地密室游戏主题进行排名,评选2021年度最受玩家喜欢的密室主题。
说明:下列界面样式仅供参考,实际完成效果美观合理即可。
1、显示数据
根据图1格式,显示t_games表中所有的数据,并且按照【票数】列进行降序排序,其实【主题种类】一列在t_games表存的是数字,需结合t_gamesType表中对应id值显示出种类文字。每行数据后面有一个投票按钮可向对应主题进行投票。
2、查询数据
可根据【主题名称】和【主题类型】进行数据查询。若【主题名称】为空,则按照【主题类型】查询,若【主题名称】不为空,则需要根据【主题名称】进行模糊查询并且也要结合【主题类型】查询。【主题类型】需是下拉框,且里面的选项是从数据库表t_gamesType中查询出来。如图所示。
3、投票功能
点击【操作】列中的投票按钮,弹出一个二次确认框,再次点击确定,可为对应的主题投票,投票成功后,该数据票数+1,如图所示:
投票数据刷新后,若票数有变化,要按新的数据进行降序排序,如图所示:
4、新增主题
点击新增按钮,进入新增页面,主题种类中的选项需要去数据库中t_gamesType表查询,上线时间需要date控件,点击新增按钮后,将数据插入数据表中,新增主题票数默认为0,并返回主页面显示最新数据,如图所示:
三、数据库设计
1、创建数据库:gamesDB。
2、创建密室排行数据表(t_games)
结构如下:
表名
:t_ games
实体名称
:密室排行数据表
主键
:id
序号 | 字段名称 | 字段说明 | 类型 | 位数 | 属性 | 备注 |
---|---|---|---|---|---|---|
1 | id | 主键 | int | 11 | 非空 | id主键列,自增1 |
2 | gamesName | 密室主题名 | varchar | 50 | 非空 | |
3 | gamesType | 密室类型编号 | int | 11 | 非空 | 外键,t_gamesType表中id |
4 | producers | 出品方 | Varchar | 50 | 非空 | |
5 | uptime | 上线时间 | date | 非空 | ||
6 | votes | 票数 | int | 11 | 非空 | 默认值为0 |
四、推荐步骤
1、使用MySql创建数据库,创建对应的2张表,按照要求插入数据。
t_games表
t_gamesType表
2、使用开发工具创建项目,使用maven添加spring、springMVC、mybatis、连接池等相关依赖坐标。
3、完成MyBatis持久层功能操作,分别针对2个表完成对应的功能编写。
4、完成业务逻辑层接口、实现类的功能实现。
5、完成控制器对应的功能编写
6、创建界面分别和控制器进行交互实现相应的功能
7 斜体样式、部署项目到Tomcat,运行访问测试项目是否正常
五、实现代码
1、MySQL数据库
