Spring Boot4.1

Create a Spring Boot Project

The standard way to start is the Spring Initializr — it generates a ready-to-run project with your chosen dependencies.

Using start.spring.io

  • Go to start.spring.io (or use your IDE's built-in Initializr).
  • Project: Maven; Language: Java; pick a recent Spring Boot version.
  • Set group/artifact (e.g. com.example / demo) and Java version.
  • Add dependencies — start with Spring Web.
  • Generate, unzip, and open the folder in your IDE.

Common starters to add

Spring WebREST APIs and MVC
Spring Data JPAdatabase access
PostgreSQL Driver / H2a specific database
Spring Securityauthentication
Validationrequest validation
Spring Boot Actuatorhealth checks & metrics

Running the app

bash
./mvnw spring-boot:run     # macOS/Linux (uses the bundled wrapper)
mvnw spring-boot:run       # Windows

The Maven wrapper (mvnw) runs the right Maven version without a separate install. The app starts on http://localhost:8080 by default.

Tip: The generated project already runs — start it before writing any code to confirm your setup works, then build up from there.
