You will learn core Spring skills step by step. This course guides you through Spring Framework 6, Spring Boot 3, REST APIs, Spring MVC, WebFlux, Security, Data JPA, Docker, Thymeleaf, Maven, and IntelliJ IDEA. You do not need past Spring experience.

Spring Boot Basics

Spring Boot builds on the Spring Framework. It removes most setup work, so you can start fast. It gives you defaults that fit common app needs.

The goal of Spring Boot is simple: let you build Spring apps without writing the same setup code each time.

Why Developers Use Spring Boot

  • It reduces setup code in new projects.
  • It follows clear defaults that help you avoid config errors.
  • It works well with Spring MVC, Data JPA, Security, and more.

Spring MVC Overview

Spring MVC helps you build web apps and REST APIs. It gives you the tools you need for routing, controllers, and views.

MVC Structure

The framework follows the Model-View-Controller design. This keeps your logic, data, and views separate.

Key Features

  • Supports both web pages and REST endpoints.
  • Provides clear request handling flow.
  • Helps you build flexible and clean apps.

Thymeleaf Template Engine

Thymeleaf is a server‑side template engine for HTML, XML, JavaScript, CSS, and plain text. It helps you build clean and easy-to-read views.

Why Use Thymeleaf

  • It integrates well with Spring MVC.
  • You can preview templates in a browser without a server.
  • It is a strong option for building UI in Spring apps.

How You Will Use Thymeleaf

In this course, you will build the view layer of a blog app with Thymeleaf. You will learn how it connects to controllers and models in Spring MVC.

Who teaches Spring 6 & Spring Boot 3 for Beginners (Includes 5 Projects)? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
