Spring Security JWT: User Sign Up + Login with Email Verification in Spring Boot

In this comprehensive tutorial, I will guide you through the process of setting up secure user authentication in a Spring Boot application. You'll learn how to implement user registration, login, and email verification using JWT (JSON Web Tokens). We'll cover essential security configurations with Spring Security, enabling you to protect your application with robust authentication mechanisms. By the end of this tutorial, you'll have a fully functional authentication system, complete with JWT handling and email verification, ready to be integrated into your Spring Boot projects.

yoooo bro you're absolutely goated

[@Jonas636_]

Thank you, straightfoward to the point!! Greetings from Brazil.

[@andiuptown1711]

Is this the new Spring Security? Literally every tutorial on yt is depreciated 😭

[@SWErikCodes]

Yep! Fully functional

[@andiuptown1711]

@@SWErikCodes Bet 🫡. Thanks again!

[@gadstam8223]

Could you create a tutorial or provide an explanation on how to deploy this API on a hosting service like Railway? Amazing video, really usefull!

[@SWErikCodes]

I did! Check out my video “how to put a coding project online”

[@Dark-wu6gr]

You deserve more views bro

[@SWErikCodes]

Glad to hear you like the content!

How is the workflow with .env file in prod, dev, stag, Specially cd/ci pip, git.ignor and where do you save the .env templat?

[@juanliendo6652]

you have to duplicate the .env file, delete all the private information leaving only the field's name and rename it to .envtemplate

[@christophercyriac1744]

So is your jwt token encrypted so nobody random can decode it and get access to the information information in the token? They would need to use the secret key to decode it in order to get all the information?

[@faresabbes5739]

i get a 403 error whenever i try to login

[@patrykcygnar1353]

Good Job bro!

[@SWErikCodes]

Glad to hear you liked the video!

[@EazyJavaLearning]

Hey Good Video bro ! But i have a question that why you dont use @Autowired for injecting the values

[@SWErikCodes]

You can use constructor based injection or @autowired both should work!

[@TejasShastri-lh2mq]

holy hell this is complicated. Just a login functionality takes so much.

[@SWErikCodes]

Haha ikr

[@kabingiri119]

Great Job Bro

Why did you choose to build the project as Gradle - Groovy instead of Maven?

[@SWErikCodes]

Gradle is designed with embedding in mind and it has great work avoidance functionality to improve the load on my server

[@SWErikCodes]

Doesn’t really matter all that much though

[@franznatavio868]

So at the end the difference isn’t that much, right? Means that I can build the same project with maven?

[@SWErikCodes]

Yes exactly, and as far as I know the only code that changes is the build file

[@la-dev]

I was learning from this video and things were ok. And when you started coding JwtService class, I totally lost and can't make any sense of the things. May be this is because I don't know how things work and which classes to call and which functions to override in order to establish security for our application. My concern and wish is that I want to learn that thing which you know to write this whole JwtService class. Because, it is only usable for a person who already have similar level of knowledge as you already have. Please share that from where should I start and what should I learn in order to understand this whole thing and that can make me capable of writing the security classes for my applications. Note: I know the basics and understand the workings of the Spring boot so that's not a problem. But I have no idea how to plan the whole security of the application and how to implement it. I've no idea of the provided classes and how to use them together to come up with JwtService type of classes. Please help, I'd be really appreciate and grateful to you.

[@TheGamer-uv7yd]

You got a sub. 👍

[@SWErikCodes]

Welcome to the channel 💪

[@learning885]

It's all sounds great, but when you sent request to /users/me you got 200 OK, but with no body, it should return 200 OK and body with info about current user

[@SWErikCodes]

You could customize it for sure

[@CodewithAby]

@learning885 @Override public String getUsername() { return email; } add this override in the user entity

[@quotes4life833]

I am using spring version 2x so i cannot use claim in jwtService whenever u used them so do u have any repo so i can refer to

[@mohammadbakeer4247]

perfect

[@SWErikCodes]

Glad you enjoyed it!

[@avhhust]

It's the old way of introducing JWT and isn't the best tbh. Spring Security features built in Oauth2 support. You can achieve same result with a few lines of code in configuration file. It also includes bunch of other features like different types of tokens, use of PKCE, refresh tokens and so on. I would suggest to start with understanding of OAuth 2.1. Because JWT by itself doesn't bring security to your application. JWT is just a type of token which is used for authorization.

[@andiuptown1711]

Is there a better tutorial or blog out there?

[@avhhust]

@@andiuptown1711 Check out @laurspilca. He has many tutorials on Spring Security, especially on Oauth2 in Spring

[@andiuptown1711]

@@avhhust ah the one that wrote Spring Start Here? Thank you!

[@EugeneKoech]

Bro could you recommended good resources to learn Java then Spring boot the best one

[@SWErikCodes]

I recommend "Java Programming and Software Engineering Fundamentals" on Coursera (audit the course for free) or anything from freecodecamp on YT for Java. For SpringBoot watch Amigoscode he is the absolute goat.

[@quotes4life833]

Hello ..your github code i cant access most of file because its extenstion is .class can you make it .java so i can see

[@SWErikCodes]

The code is all .java , head to demo src main Java com example demo and you’ll find the entire code

[@pixelatedlava]

This is a lot of work :,c

Haha ikr
