Get Ready for GraphQL!

Time to build a GraphQL API with Spring Boot. You’ll configure a project and add the GraphQL dependencies that bring these two together.

Create Your First Project

The fastest start is Spring Initializr at start.spring.io: pick Maven or Gradle, Java, the latest Spring Boot, and add the Spring Web dependency.

Initial Project Structure

Unzipped, you get a standard layout. The *Application.java class holds the main method that boots your app — run it to confirm setup before adding GraphQL.

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {
  public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);
  }
}

Bring in GraphQL Power

Add GraphQL power with one dependency: spring-boot-starter-graphql. It bundles the engine, auto-configures it, and even gives you a GraphiQL UI.

Maven: Adding the Starter

On Maven, drop spring-boot-starter-graphql into the <dependencies> block of your pom.xml and Maven pulls in every GraphQL library.

<dependencies>
  <!-- Existing dependencies like spring-boot-starter-web -->
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-graphql</artifactId>
  </dependency>
</dependencies>

Gradle: Adding the Starter

On Gradle, add the same spring-boot-starter-graphql dependency to your build.gradle using the implementation configuration.

dependencies {
  // Existing dependencies like spring-boot-starter-web
  implementation 'org.springframework.boot:spring-boot-starter-graphql'
}

Project Layout for GraphQL

Spring Boot auto-discovers your schema in src/main/resources/graphql. Create that folder and an empty schema.graphqls — your API’s contract.

Running Your GraphQL App

Run the app from your IDE, or with ./mvnw spring-boot:run / ./gradlew bootRun. Watch for “Started DemoApplication” and Tomcat on port 8080.

Verify GraphQL Endpoint

The starter auto-configures a /graphql endpoint plus a GraphiQL UI. Open localhost:8080/graphiql — if it loads, your setup works.

Check Your Setup Knowledge

You've learned how to set up a basic Spring Boot project and integrate GraphQL dependencies. Let's quickly review what you need to do to get started.

Setup Complete! What's Next?

Setup done! You used Spring Initializr, added the GraphQL starter, and prepped your schema file. Next, design your first schema in SDL.
