Creating Your First Spring Boot Project: A Step-by-Step Guide

Spring Boot is an opinionated framework that helps developers build Spring-based applications quickly and easily. The main goal of Spring Boot is to quickly create Spring-based applications without requiring developers to write the same boilerplate configuration again and again.

Creating a Spring Boot Project Using STS

STS is free, open-source, and powered by VMware. Spring Tools 4 is the next generation of Spring tooling for the favorite coding environment. Largely rebuilt from scratch, it provides world-class support for developing Spring-based enterprise applications,

Here's an example code for a simple "Hello World" Spring Boot project:

// Import required classes
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

// Mark the class as a Spring Boot application
// Define a REST controller
public class HelloWorldController {

    // Map the root URL to this method
    public String hello() {
        return "Hello, World!";

    // Main method to start the Spring Boot application
    public static void main(String[] args) {, args);

This code defines a simple REST controller that responds to the root URL ("/") with the message "Hello, World!". When the main method is run, it starts up the Spring Boot application and makes this message available at the URL. You can run this code by saving it in a file with a ".java" extension and then compiling and running it using a Java compiler and the Spring Boot CLI or IDE like IntelliJ or Eclipse.
