前言
随着国内市场经济这几十年来的蓬勃发展,突然遇到了从国外传入国内的互联网技术,互联网产业从开始的群众不信任,到现在的离不开,中间经历了很多挫折。本次开发的多维分类的知识管理系统有管理员和用户两个角色。管理员可以管理用户信息,知识分类,知识信息等,用户可以查看和下载管理员发布的各种知识信息,还可以进行评论操作。开发本程序后台用到了Spring Boot开发技术,页面设计采用VUE框架和layui样式。数据库采用关系数据库市场占有率最高的MySQL作为本程序使用的数据库,完全符合程序使用并且有丰富的拓展余地。程序从需求到设计,从开发到测试,都在功能上和性能上都不断的进行了调试,让开发的程序在使用上用户体验更美好。
末尾获取源码
SpringBoot+Vue+JS+ jQuery+Ajax...
管理员可以对用户信息进行添加,修改,删除,查询操作。
管理员可以对知识分类信息进行添加,修改,删除,查询操作。
管理员可以对知识信息进行添加,修改,删除,查询操作。
管理员可以对知识信息进行添加操作。
用户可以在首页查看多维分类的知识管理系统所有信息,可以看到有导航栏,点击就可以跳转到导航的项目。
用户可以查看知识信息,也可以下载,评论,收藏知识信息。
用户可以在个人中心修改自己的个人信息。
用户可以在个人中心里面点击我的收藏,可以看到自己收藏过的知识信息,还可以进行取消收藏操作。
