Spring Security 6 | How to Create a Login System with Spring Data JPA and JWTs [NEW 2023]

[@kelvinwarui2982]

You had me in the first 20 seconds , tutorial hell has brought me here i was almost loosing my mind on spring security

[@user-zj6iz1rl8d]

Spring is probebly the worst framework to learn their is so much bs

[@44Ricko]

@@user-zj6iz1rl8dif it wouldnt be used so much in the industry, i would never fucking touch it again.

[@cydoentis]

This video hit the nail on the head, I watched countless other videos from other people before I found this one, and the content was either outdated or poorly explained. I appreciate that you did everything from scratch and explained each step. Wish I found this video about 8 videos earlier, but I finally understand the whole implementation process for Jwt's. 11/10 will watch again.

[@aboubakrghout8180]

if u get it can u help me ?

[@vsaihruthikreddy7127]

All I could say this is an extraordinary tutorial. I tried all of the spring security tutorials but they did not cover the nitty gritty aspects of it like the jwt token creation and authorization but you just were superb. Thank you very much for uploading a gem ❤

[@adarshpandey8526]

You just revived my passion for spring boot based backend development. Thank you so much. This is the best spring security crash course I've found on KZbin even better than the inspirations you mentioned in this video. The reason is, that you used less jargon and fancy Java. You showed basic Java skills to explain an already complex spring security concept which feels smooth. Most of the creators from the Java community tend to use a lot of fancy Java design patterns and advanced Java features which causes great difficulty for freshers to understand such complex concepts. Constructive Criticism: I have one small suggestion for you, the cutting of your voice is really not good. There are no pauses between your speech, leading to you sounding monotonous even when you're not. Also, it made me rewind many times since I never understood where one sentence ended and the other began. Love your content. keep going ♥

[@maz1ogra]

This video is a compilation of everything useful that is said in the other videos, discarding all the other useless things that are said, updating it to the latest versions of spring. Liked the video, keep it up.

[@aman_deep21]

What a fantastic to the point video it is, Thank you so much Ethan for sharing valuable knowledge with all of us, my knowledge before and after watching this video has increased very much, looking forward to more of your videos. I had watched a bunch of videos on this topic, but your explanation made it much easy to follow and code along with you.

[@mrowox]

What I usually want to see in security videos is handling security for different type of roles. E.g a backend service for sellers and buyers, drivers and riders, students and teachers and so on

[@jhonandersonperaltaochoa9833]

lo que tu quieres es manejo de roles

[@anywho3934]

hey have you figured it out ? any other resources you found ? cause I have to implement it in project

[@MyBinaryLife]

this logic is implemented in the SecurityFilterChain bean in your security configuration class

Great video and working around the deprecated methods wasn’t too bad and was a very good practice of working with documentation. Thanks for putting this all together. 👏🏼👏🏼👏🏼

After thousands of videos on spring security, I finally found an excellent one

[@tyjantefinn4791]

You are a true champion by not using Lombok Sir. Lol. When you did your first round of Encapsulation, I immediately implemented Lombok ;D

[@aharoJ]

Absolute gold of a video

[@apurvasaha8871]

Finally found a video for working around the older deprecated methods. Thank you very much. Edit: Unable to generate the jwt token during login, and getting a 401 Unauthorized error response back. Might be an issue with the deprecated jwt() method in oauth2ResourceServer(oauth2ResourceServerConfigurer::jwt()). But even with the new code oauth2ResourceServer(oauth2 -> oauth2.jwt(Customizer.withDefaults())) which provides a default implementation of the oauth2ResourceServerConfigurer class its not working. If anyone has faced the same issue and solved it, Please let me know. Thank you.

[@TheMrBatica]

I had exact the same issue but I skipped the line 'daoProvider.setPasswordEncoder(passwordEncoder());' under SecurityConfiguration class -> AuthenticationManager ... i had only "daoProvider.setUserDetailsService(detailsService);" hope it helps.

Holy crap. Thank you so much; this is amazing. Top tier content. I learned so much from this compared to hours of Amigoscode or Dan Vega. Nothing against those guys, they just have so much content to get through and a lot of it is outdated. Thank you so much for putting this together. I got what I needed out of it and then some.

[@superkobke]

Well done. Had some troubles with dependencies but overall your video is quite amazing! Thank you so much!

Amazing video! Such a complex topic was explained in a relatively simple way, thank you!

[@Justdiealready6]

this guy is a true legend fr

[@koffeetalk]

Wow, first time I get it right. Thank you! This channel should have much more followers. I had some issues using Lombok, but when I did all the constructors, getters, setters manually it's finally worked! I guess I need more experience with constructors first, then use lombok.

[@unknownkoder]

I have also had issues with Lombok and I know others sometimes do as well. That is why I chose not to use it in this video.

[@ShermukhammadKarimov]

thanks for this amazing masterclass

[@SailBuddha]

This was fantastic! I followed it, but changed JPA to jdbcTemplate, because the road to Hell is paved with too much abstraction. Doing it that way, everything made perfect sense. Thank you!

[@sherlockholmes1605]

Liked the video! Here's an idea for future tutorials, can you create git branches for each chapter? this way we can go back and forth between different chapters to compare and contrast the changes.

[@anurp4173]

Wow, you had me in the first 20 seconds. Got the problem absolutely spot on. thanks

Spring Security is confusing but you did a great job. I found a lot of things in one place it helped me a lot. Thanks

[@Mihai-mb4ew]

Man, this video is top notch. It is exactly what was missing from youtube. Could you, please, share with us, how did you figure all this out? What materials did you use for documentation or how was your thought process? Or maybe is it just experience? I watched Dan Vegas' video about JWT and I was really wondering how to achieve role authorization. I wouldn't have figured it out by myself.

[@DarkHid3]

Good video, I watched it to the end, kinda hard to understand the whole thing because I've just started learning this framework but with the time for sure I will comeback and watch it again!

[@KieranMueller]

fyi if you are struggling with deprecated methods, or other things (example: I was unable to run project due to an error with the security filter chain method, request matchers specifically. You can always just downgrade the version of Spring Boot in your POM.xml to use what was used in the video and everything will work.

Double check the repository in the description, I believe you are missing the mapping for the password encoder in the SecurityConfig class.

Hey @Unknown Koder, I fixed the bug you encountered at 1:41:35, apparently this stems from a deprecated use of the jwt() Method, this is the correct way of configuring it as of Spring Security 6.1.x: .oauth2ResourceServer((oauth2) -> oauth2 .jwt(jwtConfigurer -> jwtConfigurer.jwtAuthenticationConverter(jwtAuthenticationConverter())))

[@eugenesmith9940]

Do we really need to return user credentials (even if it's wrapped into some DTO without any sort of sensitive information)? I mean is it so-called "best practice" or we can just return simple status code? Is it mandatory to return anything or we can just use void methods in such cases?

[@unknownkoder]

Its not mandatory, however some applications may use some of the users information in the frontend of the application. This is why I send back basic info in the tutorial.

Hello, good tutorial. Can you please tell me how to deal with CORS? Simply adnotating the controller wont work

Theres a CORS configuration you must setup inside the Configuration class and inside the config bean
