Project Introduction

The project is divided into two roles: administrator and reader. The main functions are:

1. Log in, log out, change password
2. The main functions of the administrator include: book management, reader management, borrowing and returning management. Add, delete, modify and check book information, check readers, check borrowing records, etc.;

3. Readers' query and query on book information, modify personal information, and check borrowing records

A total of 7 tables;

environmental needs

1. Operating environment: preferably java jdk 1.8, we are running on this platform. Other versions are also theoretically possible.
2. IDE environment: IDEA, Eclipse, Myeclipse can be used. IDEA is recommended;
3. Tomcat environment: Tomcat 7.x, 8.x, 9.x versions are available
4. Hardware environment: Windows 7/8/10 with more than 1G memory; or Mac OS;
5. Maven project: Yes; Check whether pom.xml is included in the source code directory; if so, it is a maven project, otherwise it is a non-maven project

6. Database: MySql version 8.0;

technology stack

Database: mysql5.7
Backend Framework: SpringBoot
HTML Template: ThymeLeaf
Persistence Layer: Mybatis
UI: Bootstrap

Login Authentication and User Permissions: SpringSecurity

Instructions for use

This project is managed by maven, and the detailed installation tutorial is Baidu
1. You need to download the mysql graphical management tool (such as Navicat), create a new database library, right-click the database --> run the library.sql script in the
project 2. Open the project (idea or Eclipse can be used, but you need to configure the maven environment), open src/main/resources/application.yml, and change the username and password of the database to your own mysql username and password
3. Find the BookmanagerApplication class and run the main method, open the browser server, enter localhost:8080 in the URL bar to access the system

4. If you don't want to open the project with IDE but want to run it directly, open cmd in the directory and type mvn package command, and then the corresponding jar package will be generated in the target/ directory, use "java -jar jar package name in cmd" ” to run

Precautions

1. Higher versions of mysql may report a null pointer error when logging in. If there is a problem, it is recommended to install and use mysql5.7 version
