Hello everyone, today we will learn how to develop a simple CRUD web application  using Vaadin, Spring Boot, Spring Data JPA, and H2 Database. Vaadin is the only framework that allows you to write UI 100% in Java without getting bogged down in JS, HTML, and CSS. If you prefer, you can also create layouts in HTML or with a visual designer. Vaadin apps run on the server and handle all communication automatically and securely. The GitHub repository link is provided at the end of this tutorial. You can download the source code. Technologies Used: Spring Boot 2.7.0 JDK 17 Vaadin 14.7.0 Maven 3+ npm package manager H2 Database After completing this tutorial what we will build? We will build a full-stack web application that is a basic User Management Application with CRUD features:     • Create User     • List User     • Update User     • Delete User     • View User Project Structure: Dependency Management - Maven - pom.xml <? xml version ="1.0" encoding ="UTF-8" ?>
