Complete Spring Boot Security Tutorial: Implementing JWT from Scratch

Welcome to this comprehensive Spring Boot Security tutorial, where we dive deep into implementing JWT (JSON Web Token) from scratch. In this video, I’ll guide you step-by-step through the entire process of securing your Spring Boot application using JWT.

Whether you’re a beginner or an experienced developer, this tutorial covers everything you need to know to get up and running with Spring Security and JWT. We’ll start with the basics, explaining what JWT is and why it’s essential for securing APIs. Then, we’ll move on to setting up a Spring Boot project, configuring Spring Security, and implementing JWT for authentication and authorization.

Here’s what we’ll cover:

Introduction to JWT: Understanding the structure and benefits.
Setting up a Spring Boot project with the necessary dependencies.
Configuring Spring Security for a secure application.
Creating a JWT utility class for generating and validating tokens.
Building an authentication endpoint to issue JWTs.
Adding a JWT filter to secure your API endpoints.
Testing the entire flow to ensure your application is secure.
By the end of this video, you’ll have a solid understanding of how to secure your Spring Boot applications using JWT, and you’ll be equipped with the knowledge to implement these techniques in your own projects.
