Getting Started with Spring Boot

Spring Boot makes it easy to create stand-alone, production-grade Spring-based Applications. In this tutorial, we'll set up a basic Spring Boot application.

Prerequisites

• Java Development Kit (JDK) 11 or later
• Maven 3.2+ or Gradle 6.8+
• Your favorite IDE (IntelliJ IDEA, Eclipse, etc.)

Step 1: Create a new Spring Boot project

$ spring init --name=my-app --dependencies=web,data-jpa my-app

Step 2: Create a simple controller

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        return "Hello, World!";
    }
}
