01 System Brief

The book management system is a software that uses computers and the Internet to structure and automate the management of books to improve the efficiency of book management.

02 System Features

Integrated mainstream framework, simple and streamlined development, high scalability

03 Technology

springboot + jpa + mybatis + springsecurity +javaex

rear end:

• Basic framework: SpringBoot
• Simple data manipulation: Spring Data Jpa
• Complex data manipulation: Mybatis
• Security framework: SpringSecurity
• Template engine: Thymeleaf

front end:

• javaEx is actually an encapsulation of html, css, and js. Closer to the original, it is more convenient to modify
• jQuery, to be honest, jQuery is still very comfortable to use, breaking through the limitations of various front-end frameworks

04 Operating environment

jdk1.8 + maven3 + mysql5.7
