Spring Boot 3 + Spring Security 6 - JWT Authentication and Authorisation [NEW] [2023]

In this video, you'll learn how to implement JWT authentication and authorization in a Spring Boot 3.0 application using Spring Security 6 and a Postgres database to store user credentials.

You'll see how easy it is to secure your application and protect your endpoints using JSON Web Tokens. We'll start by setting up a Postgres database and creating a user table to store our credentials.

Then, we'll configure Spring Security to use JWT and define some security rules for our application. Finally, we'll test our setup by building a simple API and using Postman to send authenticated requests.

Whether you're a beginner or an experienced developer, this tutorial will give you the tools you need to secure your Spring Boot application with JWT authentication and authorization.

I watch alot of your videos but the long ones I have never stuck to this one I stuck though the whole video and followed along every step of the way and understood everything I am so glad you done it as I followed ur example now going to be able to implement it in my own project!

[ofastora]

Absolutely what I've been looking for. Just the right amount of high level explainations for someone who's just getting into Spring. Thank you for the amazing content.

[TheEBPO]

I just started watching you, but I'm already glad I'm doing it with your style of lessons, it's awesome! Thank you so much! Hello from Ukraine!

[maitoshikigami]

This tutorial is the one I have been looking for. I spent hours looking for a way to implement spring security, however, most of the spring security tutorials that I found are outdated. Luckily, I stumble on this amazing work, my man here explained everything in depth and comprehensible. Thanks for the tutorial and keep up the good work!!

[antoniobukovac]

Great tutorial. To the point and everything is explained. Easy to follow. Great job!!

[GROOVETECHSETS]

Quality content. Thank you very much! Your channel is one of the best on YouTube for learning Java and Spring.

[david_kariuki]

This course is awesome, thank you. More detailed and clearer than the previous one.

Yesterday, I watched your previous video about Spring Security and realized that some functions are deprecated in the latest Spring Security. And I'm astonished that you uploaded an updated video today. I'm planning to build a blog website for my own and review Spring Security as well, so this video is excellent for many other developers who love Spring and for me. Keep up your great job, and wish you much luck. Happy new year🤩!

[SaltyFeaRz]

Such a helpful, important video. Just got new into creating websites with Spring and it's such the best video seen so far! Can really recommend it to everyone.

[USONOFAV]

You never disappoint. Of all spring security tutorials this is the one that make sense for me. Also, usage of lombok and an actual database (not in-memory one) is a plus.

[dennismasinde]

I was almost giving up on understanding Spring Security but now I feel like I have an eagle's eye view of what's what based on this and a number of other tutorials from other channels. Keep doing the good work.

[juliocesarvieirasantos]

I watched this video when it was released 10 months ago, and I didn't quite understand the concept, but watching it again 10 months later and understanding a lot more than last time makes me think I'm doing great progress! Thank you for the amazing content, keep up the good work!

[watchdennyplay]

You're amazing dude! You saved my diploma project with your work. Everything worked on the first try and taking the time to update this guide is just... great of you. If you are ever in Sofia let me buy you a beer. :D

[ezoz]

This is unique, definitely what I was looking for, I appreciate the time you spend doing this course

[GROOVETECHSETS]

What's going on with SpringSecurity? "HttpSecurity" is also marked for removal... All tutorials become obsolete after a few months.

[guillermoguir]

Hey AmigosCode, I congratulate you for this tutorial, for those who see the negative side of the Internet, this is a sign of generosity, and we must be grateful for that, thanks and regards!!!

[lloyd]

I would like to take the time to thank you and say that I appreciate you for your content. It's wholesome and helps me a lot!

[mohammedharoon]
