Introducción al proyecto

El sistema se divide en dos roles: administrador y usuario ordinario;
el rol de administrador incluye las siguientes funciones:
gestión de préstamo de libros, gestión de información de libros, gestión de clasificación de libros, gestión de usuarios, gestión de roles, gestión de devolución de libros, página de inicio de sesión y otras funciones.

Los roles de usuario incluyen las siguientes capacidades:

Gestión de préstamos, recuperación de libros, verificación de préstamos y registros de devolución, verificación de detalles de libros, gestión de devolución de libros, página de inicio de sesión y otras funciones.

pila de tecnología

1. Servidor: SpringBoot

2. Interfaz: JSP+CSS+JavaScript+bootstrap

Instrucciones de uso

1. Use Navicat u otras herramientas para crear una base de datos con el nombre correspondiente en mysql e importe el archivo sql del proyecto
2. Use IDEA/Eclipse/MyEclipse para importar el proyecto Al importar desde Eclipse/MyEclipse, si es un proyecto maven, seleccione maven;
si es un proyecto maven. Después de que la importación sea exitosa, ejecute el comando maven clean;maven install y luego ejecútelo;
3. Cambie la configuración de la base de datos en el archivo de configuración application.properties en el proyecto a su propia configuración
4. Ejecute el proyecto e ingrese localhost en el navegador: 8083/ Iniciar sesión
