Spring Boot MVC REST Controller Example & Unit Tests

Date: 2024-06-28

This tutorial demonstrates creating a RESTful CRUD API for managing books using Spring Boot and Spring Data JPA. It covers setting up a PostgreSQL database (using Docker), defining a Book entity and repository, building a @RestController to handle HTTP requests, implementing global exception handling, and writing unit tests. The @RestController simplifies creating REST controllers by combining @Controller and @ResponseBody, directly returning data in the response body. The tutorial leverages Spring Data JPA's JpaRepository for efficient database interaction.
