Spring java config

This document provides an overview and configuration steps for setting up a Spring MVC web application using Java configuration, Hibernate ORM, and Gradle. Key aspects covered include setting up the Spring configuration, configuring Hibernate and the database connection, implementing CRUD operations, and enabling REST APIs. The application uses JSP and JSTL for views and runs on an embedded HSQLDB database with Tomcat as the web container.
