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
1id主键int11非空id主键列,自增1
2gamesName密室主题名varchar50非空
3gamesType密室类型编号int11非空外键,t_gamesType表中id
4producers出品方Varchar50非空
5uptime上线时间date非空
6votes票数int11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

gamesdb.sql

  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

-- ----------------------------

-- ----------------------------
INSERT INTO `t_gamestype` VALUES ('1', '恐怖');

public class TGamesController {
	@Resource
	TGamesService tGamesService;
	
	//查询所有数据,模糊查询
	@RequestMapping("/tGamesList")
	public String accountList(Model model,String keyword,String type){
		List<TGames> selectAll = tGamesService.selectAll(keyword,type);
		model.addAttribute("selectAll",selectAll);
		return "games";
	}
	
	//进入添加的方法
