Setting up Spring Boot for GraphQL
Configure a new Spring Boot application and integrate the necessary dependencies for GraphQL API development.
Setting up Spring Boot for GraphQL is a free GraphQL APIs with Spring Boot lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the GraphQL APIs with Spring Boot learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
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.
