Intro to Spring Boot

Spring Boot lets you build stand-alone, production-ready Spring apps fast — it slashes configuration so you can get running with minimal fuss.

What is Spring Initializr?

Spring Initializr is a web tool that bootstraps a new Spring Boot project — structure and dependencies generated for you, ready to import. A project wizard.

Initializr in Action

Use Spring Initializr right in your browser at start.spring.io — or through IntelliJ and VS Code, which integrate it for even smoother project creation.

Define Your Project

Set your project’s metadata: build tool (Maven or Gradle), language (Java), Spring Boot version, group/artifact IDs, package name, and Java version.

Choose Your Ingredients

Dependencies are the libraries you need. For a web app, add Spring Web — it brings everything for REST APIs, including embedded Tomcat.

Get Your Project Ready

Hit Generate to download a ZIP. Unzip it and open the project in your IDE — most import Maven or Gradle projects out of the box.

Inside Your New Project

Know your project layout: pom.xml for dependencies, src/main/java for code, src/main/resources for config, and src/test/java for tests.

Entry Point of Your App

Every app needs a main class. @SpringBootApplication bundles @Configuration, @EnableAutoConfiguration, and @ComponentScan, and main calls SpringApplication.run().

Hello Spring Boot Console

Let’s run a minimal Spring Boot app that just prints to the console — no web server yet. SpringApplication.run() starts the whole Spring context.

package com.coddykit.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);
    System.out.println("Spring Boot application started!");
  }
}

Recap: Project Setup

Great work! You’ve covered Spring Boot basics, creating a project with Initializr, key settings, the project structure, and the main application class.
