Introduction

Spring Boot and Vaadin is a powerful combination for building web applications with Java. This guide will provide an introduction to integrating Spring Boot with Vaadin, explain the basics of Vaadin, and offer sample code with explanations for its implementation.


Why Use Vaadin with Spring Boot?

Vaadin is a Java framework for building modern web applications. When integrated with Spring Boot, it offers several advantages:

  • Java-Based: Vaadin allows you to build web apps using Java, eliminating the need for complex JavaScript.
  • Rich User Interfaces: Vaadin provides components and tools for creating responsive and interactive user interfaces.
  • Tight Integration: The Spring Boot and Vaadin integration simplifies the development of web applications using Java.

Getting Started with Spring Boot and Vaadin

To start using Spring Boot with Vaadin, follow these steps:

  1. Create a Spring Boot project using the Spring Initializr or your preferred IDE.
  2. Add the Vaadin Spring Boot Starter dependency to your project's pom.xml (Maven) or build.gradle (Gradle) file:
<!-- Maven -->
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-spring-boot-starter</artifactId>
    <version>XX.X.X</version>
</dependency>
        
// Gradle
dependencies {
    implementation 'com.vaadin:vaadin-spring-boot-starter:XX.X.X'
}
  1. Create a Vaadin UI class to define the layout of your web app:
@Route("")
public class MainView extends VerticalLayout {
    public MainView() {
        H1 header = new H1("Hello, Vaadin!");
        add(header);
    }
}
  1. Run your Spring Boot application, and access your web app in a web browser.
