Java实战角色权限后台脚手架系统的实现流程
作者:qq_1334611189
只学书上的理论是远远不够的,只有在实战中才能获得能力的提升,本篇文章手把手带你用java+Springboot+Maven+myBaits-Plus+Vue+Element-UI+Mysql实现一个角色权限后台脚手架系统,大家可以在过程中查缺补漏,提升水平
Springboot框架+myBaits-Plus+MySQL实现的角色权限后台管理脚手架系统实战项目,实现的是所有系统最基础的后台管理功能,有了这个脚手架,以后开发别的项目就在这上面快速增加功能即可。本系统主要实现的功能有:菜单管理、角色管理、用户管理、登录、登出,不同的角色分配相应的权限,用户分配不同的角色登录后显示相应被分配的功能。
本系统采用前后端分离的思想设计,后端采用springboot微服务架构,主要包含一个网关服务和一个权限管理服务,开发其他功能可以再创建其他的微服务,前端采用vue+element-UI实现。
1.本系统开发所需的基础环境及版本:
软件 | 版本 |
jdk | 1.8 |
MySQL | 5.7 |
maven | 3.6.1 |
nacos | 1.1.4 |
Redis | 5.0.10 |
Node | 14.17.3 |
