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
