基于java springboot框架的电子发票管理系统、毕业设计，附源码

今天给大家介绍一个电子发票管理系统，适合电子发票的管理，用户等级关系明确，功能丰富。

功能介绍

这个电子发票管理系统分为三级关系，系统管理员，租户管理员，用户。 三者关系，系统管理员管理全部，租户管理员比如为市教育局，租户为学校，用户为老师。租户的授权期限到了，租户下的所有用户都不能登录。 每个租户管理员只能管理本租户内的租户和用户，用户只能管理本租户内的电子发票。该系统只针对电子发票管理，不开电子发票。

开发环境

开发工具：IDEA、Jdk1.8、SpringBoot2.0.6版本项目

数据库：MySQL5.7

所用技术

前端：BootStrap、EasyUI、JQuery、HTML5+CSS3、Ajax

后端：SpringBoot+spring-data-jpa

安全控件：SpringSecurity

页面采用：Thymeleaf
