背景及意义
目前许多人仍将传统的纸质工具作为信息管理的主要工具，而网络技术的应用只是起到辅助作用。在对网络工具的认知程度上，较为传统的office软件等仍是人们使用的主要工具，而相对全面且专业的信息管理软件仍没有得到大多数人的了解或认可。本选题则旨在通过标签分类管理等方式，实现教研的各种功能，从而达到对科研管理系统的管理。 科研项目管理系统，以项目化管理为思想，以现实中管理制度为核心，对科研项目申报、项目开题、项目合同、实施进度、项目风险分析及控制计划、项目经费、项目质量、项目文档、科研成果等科研活动全面管理，实现科研项目“管理标准的沉淀优化、组织流程的优化、管理水平的提升、内外部资源整合的延伸”，保障科研项目完成与落实，出人才、出成果、出效益，提高竞争力。 主要功能项目主要分为3个角色，分别是超级管理员，教师和学生，超级管理员具有项目所有的权限，包括有用户管理，角色管理，权限管理，项目管理，申报管理，变更管理，结题管理，数据字典等功能；学生学生负责对项目的申报，变更，结题申请等，教师负责对学生提交的项目进行审核。 项目搭建环境 > java jdk版本：1.8及以上 > 后台框架：java spring springmvc mybatis springbotoot等 > 前端框架：html css javascript vue等 > 开发工具： idea或者eclipse都可 > 数据库: mysql 5.7及以上 > 服务器: tomcat > 更多内容可查看：http://projecthelp.top 部分核心代码 import org.springframework.stereotype.Service;
