## Overview

This is a Spring MVC product-and-type management application with server-rendered pages and a separate JSON API. Users list, create, edit, and delete products and types; product forms also load types so a product can reference one. Both entry points delegate to services, which delegate persistence to JPA repositories. The tree includes JSP views and entity paths, but their implementations and application configuration were not sampled, so those links are shown only where supported by the controllers.

Main entry points: [`src/main/java/groupe2/controller/ProductController.java`](https://github.com/gat0sy/gestion_spring_mvc-l3gl2/blob/main/src/main/java/groupe2/controller/ProductController.java) (Product pages), [`src/main/java/groupe2/service/impl/TypeServiceImpl.java`](https://github.com/gat0sy/gestion_spring_mvc-l3gl2/blob/main/src/main/java/groupe2/service/impl/TypeServiceImpl.java) (Type service), [`src/main/java/groupe2/controller/TypeController.java`](https://github.com/gat0sy/gestion_spring_mvc-l3gl2/blob/main/src/main/java/groupe2/controller/TypeController.java) (Type pages), [`src/main/java/groupe2/service/impl/ProductServiceImpl.java`](https://github.com/gat0sy/gestion_spring_mvc-l3gl2/blob/main/src/main/java/groupe2/service/impl/ProductServiceImpl.java) (Product service)
