## Overview

This is a role-based student leave-management system. The documented workflow covers leave information, dean and principal approvals, leave cancellation (销假), and overdue reminders, alongside role and account administration. The README describes a Vue frontend and Spring Boot/MyBatis-Plus backend, but the tree contains no implementation files, so component paths and internal call relationships cannot be verified; the graph shows only documented capabilities and access.
