How vijeemani/book_app works

Pubhub is a Spring MVC bookstore with user registration and account administration alongside book browsing, cart/order handling, and order-history management. The main workflow routes web requests through controllers and services to Spring Data repositories; JSPs render responses. The README specifically documents listing, editing, deleting, activating, and deactivating users, though sampled code does not establish the detailed routes for each operation. Relationships for unsampled controllers and services use SOURCE INDEX references; uncertain integrations are omitted.
