1、项目介绍及开发技术

1.1 项目介绍

网络的广泛应用给生活带来了十分的便利。所以把实训管理与现在网络相结合，利用java技术建设实训管理系统，实现实训管理的信息化。则对于进一步提高实训管理发展，对实训管理系统能起到不少的促进作用。本系统能够通过互联网得到广泛的、全面的宣传，让尽可能多的用户了解和熟知实训管理系统的便捷高效，不仅为群众提供了服务，而且也推广了自己，让更多的群众了解自己。

本系统设计的现状和趋势，从需求、结构、数据库等方面的设计到系统的实现，分别为管理员、教师和学生的实现。论文的内容从系统的设计、描述、实现、分析、测试方面来表明开发的过程。本系统根据现实情况来选择一种可行的开发方案，借助java编程语言和MySQL数据库等实现系统的全部功能，接下来对系统进行测试，测试系统是否有漏洞和测试用户权限来完善系统，最终系统完成达到相关标准。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

2、系统功能模块设计

学生：注册登录、首页、论坛、公告信息、实训模块、实训实施、个人中心（个人信息、成绩、考勤、请假、实训成果）。

老师：注册登录、个人中心、学生管理、成绩管理、论坛管理、公告信息管理、考勤管理、请假管理、实训模块管理、实训实施管理、实训成果管理、轮播图管理。

管理员：首页、个人中心、管理员管理、老师管理、学生管理、成绩管理、论坛管理、公告信息管理、考勤管理、请假管理、实训模块管理、实训实施管理。
