Fantastic tutorial, probably the clearest tutorial I've ever watched on a pretty complicated subject. Thank you very much!

wow, these are the best tutorials on Spring Security I have ever found on the Internet. Please keep up the good job :)

Sir, you have made Spring Security so easy to understand. Thank you so much for your efforts😀

Your way of explaining complicated concepts in a simple manner is outstanding! Thank you so much!

Great Job Koushik!!! I like your teaching style and JavaBrains has been my main source of learning SpringBoot and java related stuff lately!!

I've been struggling with Spring Security for days. Your tutorial made me able to install an authentication system on my app in two hours. THANKS!

I saw the whole spring security basic videos, everything till now was explained well. anyone can easily understand these spring security topics. Thank you for your time and effect

You are doing a great service by sharing all these...no praise will ever be enough..👍👍👍

I am big fun of your teaching. I don't even want to go for other resources unless I don't find in Java Brains. I really appreciate your contribution to my life. You are such important to me."live long and God bless you."

I've watched almost every single video I could find on this subject and this was the clearest and most helpful and actually worked. Thank you for your help!

This is what is required on RU-vid. Kudos sir Bring full stack courses also. I bet 1 million is not far away then.🙌

Thanks sir, these are the best tutorials on Spring Security I have seen on the Internet

You are doing fabulous work Sir...( Y) Hats off to you for giving so much content to the community for free.

Thank you so much! You explain so clearly, much better than all the paid courses online! 😄

Clear and simple, managed to implement my own JPA authorization provider thanks to this video. Great Job !

Thank you once again, Kaushik for your time and teaching!

This security series is absolutely amazing !! All aspects for each type covered.. 😀👍

Thank you so much, its always pleasant to watch your videos, crystal clear, in details and precise to point. Thank you so much for your tutorial.

By Far the Best Explanation of Spring Data JPA with Spring Security...got many concept cleared out of this Tutorial

I have watched a ton of similar videos, but your videos are best by far!

Thanks, this is the clearest from scratch video i found so far..so difficult to explain yet you made it look easy

Thanks for coming back !!

Clearest tutorial with minimum time. Easy to understand. Thank you for wonderful lectures sir.

thank you very much for putting this together. Your explanations are very clear, concise and to the point!

Great start to the weekend.. God bless.. Please cover JWT, OAuth and SAML

Thank you for uploading such video's. Really helps a lot in Interviews.

This is one of the best tutorial i have seen in my entire life :D Thank you so much.

Highly important guys.. at @01:14 be aware, the role field must be save with "ROLE_" prefix in the DB, (dont know the reason). I wasted alot of time because I entered the authorization role mapping value which is without the "ROLE_" prefix. thank for the tutorial sir, BIG LIKE!

Really AWESOME!! One of the best videos I watched.

I've been looking for such tutorial. Great video. Thank you!

SIR the whole day I've been trying to get this to work... then 10 minutes in this video and it works now. I really thank you a lot!!!

The best tutorial i've seen on youtube !! Thanks man !

This was amazing. So well planned and executed and explained wonderfully. You helped me grasp this which I was struggling with based on online text based tutorials that I had found. I will definitely be sending anyone I know trying to learn this as well here!

This is pure awesomeness thankyou very much. Amazing!!!!

Very good tutorial, nice and clear explanations. Thanx a LOT!!

Finished the tutorial! great job and explanation

Sir, hatsoff to you.. you made learning spring security enjoyable for me.. being dyslexic I hated spring security..

Great Video. God bless you. Regards from Mexico!

Excellent, Thank you Kaushik, May God bless you!

Epic! Thank you! Please talk about integration with JWT

Nice One Koushik, keep the good work up. With addition to all the information, would like to add, spring by default adds "ROLE_" to whatever the role we are trying to check for the user. Thats why Kaushik has inserted ROLE_USER in the roles column of the user table. Now why we are trying to access different urls, spring check the role using the class ExpressionUrlAuthorizationConfigurer which get called from the overriden method configured having HttpSecurity as parameter. Check the implementation for the method hasRole in the method chaining.

Tjank you so much brother... It was the best spring security tutorial i've ever watched so far...💜

Thanks for your hard effort to make the things done. Awesome

Yes Correct, read query many times for authentication/authorization, we might consider using LDAP. LDAP has fast read query.

Best I've ever seen on youtube .. thks man 😀👍
