A full-stack web application built with Java 21 and Spring Boot 4 for managing a library's resources. Features a Thymeleaf web interface, REST API with Swagger docs, Spring Security with role-based access, and CI/CD deployment to AWS Elastic Beanstalk.
The system enables librarians to manage books, authors, and categories while allowing members to borrow, return, and reserve books. It features a full Thymeleaf web interface with Bootstrap 5, pagination, sorting, and real-time validation.
Built with a layered architecture — controllers handle HTTP, services contain business logic, and repositories manage persistence. Spring Security enforces role-based access control across three user roles: Admin, Librarian, and Member.
The REST API is documented with OpenAPI/Swagger. The project includes comprehensive unit and integration tests with JaCoCo coverage, and is deployed to AWS Elastic Beanstalk via a GitHub Actions CI/CD pipeline.
Full CRUD for books with ISBN validation, category assignment, multi-author support, and automatic stock tracking across borrows and returns.
Members borrow books with stock and limit validation. The system tracks borrowing date, due date, and return date — with overdue detection built in.
Reserve unavailable books, cancel, or convert reservations into active loans when copies become available. Status lifecycle: active → completed/cancelled.
Role-based access control (Admin/Librarian/Member) with BCrypt passwords, custom login page, remember-me, CSRF protection, and method-level security.
Full web interface with Bootstrap 5, pagination, sorting, and server-side validation. Plus a complete REST API documented with Swagger/OpenAPI.
Deployed to AWS Elastic Beanstalk with RDS PostgreSQL, automated via GitHub Actions CI/CD — tests, builds, and deploys on every push to main.
Core language for all business logic, entities, services, and controller implementations.
Application framework providing auto-configuration, dependency injection, security, and web layer.
ORM persistence with Hibernate — entities, custom queries, and repository pattern for all 7 entities.
PostgreSQL for production/dev, H2 in-memory for tests. Multi-profile configuration for seamless switching.
Authentication and authorization with BCrypt, role-based access, custom login, and CSRF protection.
Server-side template engine for the web interface, styled with Bootstrap and enhanced with Bean Validation.
REST API documentation auto-generated with SpringDoc — interactive UI for testing all endpoints.
Cloud hosting with RDS PostgreSQL, load balancer, and automated deployment via GitHub Actions CI/CD.
Unit tests with Mockito, integration (E2E) tests, and code coverage reporting with JaCoCo.
Full source code, entity model, REST API, Thymeleaf views, tests, and CI/CD pipeline — all available on GitHub. Clone the repo, set up PostgreSQL, and run with Maven.
