Library book Management System using Spring Boot

Abstract This paper presents the design and implementation of a Book Management System (BMS) developed using Spring Boot, a production-grade Java framework for building microservice-ready applications. The system supports library workflows including book cataloguing, user management, borrowing/returning operations, search, and basic analytics. Emphasis is placed on a RESTful API architecture, layered design (controller-service-repository), persistent storage with a relational database (PostgreSQL/MySQL), and security using Spring Security with JWT. We evaluate the system on functional correctness, response time for common operations, and concurrency handling. The solution demonstrates scalability, maintainability, and extensibility suitable for small-to-medium library environments or as a backend for web/mobile frontends.
