Web Services Project with Spring Boot and JPA / Hibernate

This is a Java Spring Boot project that implements a Web Services system using JPA (Java Persistence API) and Hibernate. The main goal is to create an application with CRUD (Create, Retrieve, Update, Delete) functionalities, exception handling, and layered architecture.

Technologies Used

• Spring Boot: A framework to simplify configuration and development of Java applications.
• Spring Web: A module of the Spring Framework for creating web applications.
• Spring Data JPA: Eases the implementation of JPA-based repositories.
• Hibernate: An object-relational mapping framework for Java.
• H2 Database: An in-memory database for testing.
• Java 17: The primary programming language.
• Maven: A dependency management tool.
