# 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。  
![数据显示页面][47069f42091443a1aba91be2aa44a2b8.png]

## 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。  
![图2 查询功能][2]

## 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：  
![图3 给对应主题投票][3]  
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：  
![图4 投票成功后,要更新最新排名顺序][4]

## 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：  
![图5 新增页面][5]

# 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

<table> 
 <thead> 
  <tr> 
   <th>序号</th> 
   <th>字段名称</th> 
   <th>字段说明</th> 
   <th>类型</th> 
   <th>位数</th> 
   <th>属性</th> 
   <th>备注</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>1</td> 
   <td>id</td> 
   <td>主键</td> 
   <td>int</td> 
   <td>11</td> 
   <td>非空</td> 
   <td>id主键列，自增1</td> 
  </tr> 
  <tr> 
   <td>2</td> 
   <td>gamesName</td> 
   <td>密室主题名</td> 
   <td>varchar</td> 
   <td>50</td> 
   <td>非空</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td>3</td> 
   <td>gamesType</td> 
   <td>密室类型编号</td> 
   <td>int</td> 
   <td>11</td> 
   <td>非空</td> 
   <td>外键,t_gamesType表中id</td> 
  </tr> 
  <tr> 
   <td>4</td> 
   <td>producers</td> 
   <td>出品方</td> 
   <td>Varchar</td> 
   <td>50</td> 
   <td>非空</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td>5</td> 
   <td>uptime</td> 
   <td>上线时间</td> 
   <td>date</td> 
   <td></td> 
   <td>非空</td> 
   <td></td> 
  </tr> 
  <tr> 
   <td>6</td> 
   <td>votes</td> 
   <td>票数</td> 
   <td>int</td> 
   <td>11</td> 
   <td>非空</td> 
   <td>默认值为0</td> 
  </tr> 
 </tbody> 
</table>

# 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`  
![在这里插入图片描述][c818f4ac8fc74ef980e81efadeb10ff1.png]  
`t_gamesType表`  
![在这里插入图片描述][e51058e493754b9899832075d85b0fcf.png]

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 #
