Purpose

I started learning Spring Boot last year and quickly realized there are countless free resources available. The problem wasn’t finding materials - it was identifying which ones were actually worth my time. I wasted hours on outdated tutorials and fragmented content before discovering the high-quality resources I’ll share in this post.

This is a curated collection of the best free Spring Boot learning resources I’ve personally used and validated. I’ve organized them by type so you can choose what fits your learning style. Everything listed here is completely free and covers current Spring Boot versions (3.x and 4.x).

Official Spring Boot Resources

I always recommend starting with official resources. They’re maintained by the Spring team, kept up-to-date, and cover best practices directly from the source.

Spring Boot Official Documentation

The official documentation at https://docs.spring.io/spring-boot/docs/current/reference/html/ should be your first stop. I reference it constantly even now.

What I found most useful:

  • Getting Started Section - Quick introduction with code examples
  • Using Spring Boot - Core concepts like auto-configuration
  • Production-Ready Features - Actuator, metrics, health checks
  • How-To Guides - Practical solutions to common problems

Here’s a simple controller example from the official docs:

@RestController
@RequestMapping("/api")
public class HelloWorldController {


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

Spring Boot Samples

The Spring team maintains sample projects at https://github.com/spring-projects/spring-boot-samples. I cloned this repository and ran multiple examples to understand different patterns.

Available samples include:

  • Web applications with Spring MVC
  • Data access with Spring Data JPA
  • Security configurations
  • Testing patterns
  • Reactive programming with WebFlux

To run a sample:

Terminal window
git clone https://github.com/spring-projects/spring-boot-samples.git
cd spring-boot-samples-web-ui
./mvnw spring-boot:run

Spring Initializr

I use https://start.spring.io/ to generate all my new Spring Boot projects. It lets you select dependencies and generates a ready-to-run project.

What I like:

  • Pre-configured templates
  • Maven and Gradle support
  • IDE integration for IntelliJ, Eclipse, VS Code
  • Only includes dependencies you actually need

Spring Guides

The guides at https://spring.io/guides are step-by-step tutorials I recommend for beginners. They cover specific tasks with complete code examples.

My favorites:

  • Building a RESTful Web Service
  • Accessing Data with JPA
  • Securing a Web Application
  • Building REST Services

Typical project structure you’ll see:

src/main/java/com/example/demo/
├── DemoApplication.java
├── controller/
│   └── UserController.java
├── service/
│   └── UserService.java
├── repository/
│   └── UserRepository.java
└── model/
    └── User.java

YouTube Channels and Video Tutorials

I learn best through video tutorials. These channels provide high-quality Spring Boot content for free.

Top YouTube Channels

1. Spring Academy (Official) https://www.youtube.com/@SpringAcademy

I follow this channel for the latest Spring Boot features and official tutorials. They post weekly content from the Spring team.

2. Amigoscode (Nelson) https://www.youtube.com/@amigoscode

Nelson’s “Spring Boot Tutorial For Beginners” playlist got me started. His project-based approach works well - you build complete applications rather than just snippets.

3. Java Brains (Koushik) https://www.youtube.com/@javabrains

Koushik explains concepts clearly with practical examples. I used his Spring Boot tutorial series to understand dependency injection deeply.

4. Dan Vega https://www.youtube.com/@danvega

Dan covers new Spring Boot features quickly. I watch his videos to stay current with updates.

5. Tech Primers https://www.youtube.com/@TechPrimers

Good for microservices and real-world application building. I learned Docker and Spring Cloud integration from his tutorials.

Based on my experience, here’s a structured path through video content:

Beginner (40-60 hours):

  • Spring Boot Quick Start (5 hours)
  • Spring Boot with Spring Data JPA (8 hours)
  • Spring Boot Security (10 hours)
  • Spring Boot Testing (8 hours)

Intermediate (60-80 hours):

  • Spring Boot Microservices (15 hours)
  • Spring Boot with Docker (8 hours)
  • Spring Boot Reactive (12 hours)

Advanced (50-70 hours):

  • Spring Boot Performance (10 hours)
  • Spring Boot Production (12 hours)
  • Spring Boot Architecture (15 hours)

Video Learning Tips

What worked for me:

  • Code along with every video - don’t just watch
  • Pause frequently to experiment with modifications
  • Take structured notes
  • Build upon examples with your own features

Free Online Courses

These platforms offer structured courses you can audit for free.

Coursera

Spring Boot Framework by VMware https://www.coursera.org/learn/spring-boot

I audited this course for free. It covers:

  • Spring Boot basics
  • Data access with JPA
  • Security fundamentals
  • Testing and deployment

The free audit gives you access to all videos and materials. You only pay if you want a certificate.

edX

Building Cloud Apps with Spring Boot https://www.edx.org/learn/cloud-computing

Microsoft’s course focuses on cloud-native patterns and microservices. I used it to learn Azure deployment and distributed systems concepts.

FreeCodeCamp

Full Spring Boot Course https://www.freecodecamp.org/news/learn-spring-boot

Complete 4+ hour video course with GitHub projects. I built the todo application following along - it covers REST APIs, Spring Data JPA, Spring Security, and deployment.

Hyperskill (JetBrains)

Spring Boot Developer Track https://hyperskill.org/tracks

Interactive coding problems with immediate feedback. I like their in-browser IDE for quick practice sessions without setup.

Practice Platforms and Projects

The only way to truly learn Spring Boot is to build things. Here are platforms I use for practice.

Coding Challenges

Codewars - Java and Spring-specific katas HackerRank - Java problem-solving track LeetCode - Algorithm practice with Java

I use these to sharpen my Java skills, which directly improves my Spring Boot code.

public class Todo {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private Boolean completed;
    private LocalDateTime createdAt;
}

  • Join study groups

Project-Based Approach

  • Learn by building real things
  • Start with simple projects
  • Increase complexity gradually
  • Deploy your applications

Common Pitfalls I Encountered

Don’t make my mistakes:

  • Don’t jump into advanced topics too early
  • Don’t skip testing fundamentals
  • Don’t ignore documentation
  • Don’t copy-paste without understanding
  • Don’t learn outdated versions (pre-3.0)

Do these instead:

  • Start with Spring Boot 3.x/4.x
  • Read official docs first
  • Practice consistently
  • Join communities
  • Build real projects

Summary

The best free Spring Boot learning resources I’ve found:

  1. Official docs - Start at spring.io
  2. YouTube - Amigoscode, Java Brains for comprehensive tutorials
  3. Courses - Coursera, edX (audit for free)
  4. Practice - Build real projects, use Codewars/HackerRank
