How sonalisahu728/librarymanagement works
This is a small Spring Boot library catalog for managing book records. The documented workflow is a browser/client making REST requests to the book controller, which delegates through the service and repository layers to persistent storage. The README also describes a static web interface, a Book entity, and PostgreSQL persistence configured for Hibernate and Spring Data JPA. No source excerpts were provided, so relationships below rely on the README’s architecture and feature descriptions; implementation details beyond those documented are omitted.
Main entry points: BookController.java Book controller · BookService.java Book service · BookRepository.java Book repository · Book.java Book entity
