基于SpringBoot的游戏防沉迷系统的设计与实现

摘   要

随着网络游戏市场的持续火爆,其最明显的负面影响----“网络游戏沉迷问题”已成为当前社会普遍关心的热点问题。根据2010年8月1日实施的《网络游戏管理暂行办法》，网络游戏用户需使用有效身份证件进行实名注册。为保证流畅游戏体验，享受健康游戏生活、保护未成年人身心健康，未满18岁的用户将受到防沉迷系统的限制,在全国范围内强制推行网络游戏防沉迷系统。而这些网络游戏防沉迷系统主要由游戏生产商推出，因此每款游戏防沉迷系统只针对一款游戏，不能解决青少年玩多款游戏而拥有过多的游戏时间的问题。因此，有必要设计一种针对终端用户的游戏沉迷监控系统，以解决上述问题。
  防沉迷软件的开发可以有效的掌控好未成年人的具体上网时间，合理的安排好时间的利用方向，使得劳逸结合。

本系统使用后台使用Springboot框架开发，数据库使用MySQL，完成系统功能模块的开发。

ABSTRACT

As the online game market continues to hot, its most obvious negative impact ---- "addiction to online games" has become a hot issue of general concern in the current society. According to the Interim Measures for the Administration of Online Games, which came into effect on August 1, 2010, users of online games need to register with their real names using valid id cards. Users under the age of 18 will be subject to a nationwide anti-addiction system to ensure smooth gaming experience, enjoy a healthy gaming life and protect the physical and mental health of minors. And these online game anti-addiction system is mainly launched by game manufacturers, so each game anti-addiction system is only for one game, can not solve the problem of teenagers playing multiple games and having too much game time. Therefore, it is necessary to design a game addiction monitoring system for end users to solve the above problems.

The development of anti-addiction software can effectively control the specific Internet time of minors, reasonable arrangement of the use of time direction, so that the combination of work and rest.

This system uses Springboot framework development background, database using MySQL, complete the development of system function modules.

Key words :Springboot framework; Anti-addiction system; The MYSQL database
