To all who are searching for building a login system using spring security, this is best one I have found. Perfect in all sense. THanks bro. Please do build more videos. You are doing a great job.
Hey Bro.
Have you implemented the code . When i login the page i got bad credentials.
Either your username or password might be wrong
very good content...
Thanku sir..!!
this is good way of teaching with such relaxed explanation . A billion thanks to the tutor i have been using old version of spring security i got confused to align with these new changes.
kindly do more videos on spingboot and microservices.
as continuation for this can you make a video on jwt and oauth2
Thanks.
A new tutorial for microservices with real-world video streaming project is now available

this is called Best
it’s perfect 😅
Sir please bring more Spring Boot tutorials and its important topics
Malayali bro :) . I love your slang .❤. from TN
Thank you for great video and very good explanation!
Can I may one questions? Why we have two instances/beans (lines 32, 69) of one classes MyUserDetailService ?
cool man
I LOVE YOU
after checking all spring boot website and all of these tutorials with deprecated calsses this video just showed up
great
This was a great help, i was trying to make a register page and it worked; tho i'm having some difficulty trying to give MyUser more attributes, everytime i give them a birth date or an email i can't register them anymore on the DB. I think it has something to do with the UserDetails but don't know how to proceed.
What's the error you are getting? Any error messages?
Thank you so much for the tutorial, I was able to verify credentials from Db, This is the very first time I was able to do it. But one thing, error pages are being shown--- like 403 or 404.htmls, what could be the reason? I am seeing only the default pages provided by Spring.
Great video , so simple to understand, thank you! Greetings from Argentina!
PD: There is an extension to see colored console messages? Mine it's plain white, thanks!
Perfect people not exists !
Mr.GC : Are you sure ?
thank you sir for this content !!
you have like, thanks
Great tutorial! Clear, chill and great overall tutorial! But I just had a question, how would I go about retrieving the user id?
Thanks!
I believe you want to get all the users and their IDs. This can be done by creating a new GET endpoint.
For example, at 31:38, you can
- Create a new GetMapping("/register/get-registered-users") function.
- Use myUserRepository.findAll() to get all the registered users.
- Take the username and their ID and return it as the endpoint response.
@@GenuineCoder Ahh that's what I thought matching the username in the db. Is there no other way of doing this in a controller? Using Principal or something along those lines?
@@lorenzo. I understand your question better now. You want to find the current already logged-in user while accessing an endpoint, right?
There are multiple ways to do this. For example, on every endpoint function, you can inject a Principal object and get the username from it.
@GetMapping(value = "/user/get-logged-in-user")
public String getUsername(Principal principal) {
return principal.getName();
}
Here's a tutorial for this www.baeldung.com/get-user-in-spring-security
Hi, It's a great video. I am facing a slight problem. My Authentication Success Handler part is not working properly. I have checked the codes but there isn't problem. Is there anything I can do solve this ?
Hi Sir, I am getting "please sign in" error when i do user registration using postman and as csrf is also disabled. Please suggest any other changes i need to do with spring security 6
Thank you very much.
But in my case I faced the problem of incorrect redirection after click 'Log in ' button'(nothing happened). I solved it by replacing th:action in custom_login.html to . I use 3.2.5 version of springboot.
What's the difference with using OAuth2, and when do we have to use each of them?
This is an excellent video, and it was a very good revision for me as I have not used this for a while.
I have two questions if I may please:
1) when using Spring Boot as a Rest API, when I am only returning JSON, and i have a seperate front-end, I was having issues with filters, and I had to implement my own authentication end point in a controller, is this normal ? How to use filters with REST API?
2) Is it possible to use HandlerInterceptor instead of filters ?
OMG, at 47:38, look at the names of those classes, no wonder so many people are turned off by Java code, I love Java, but these names are awful
1. Using filters to do manual authentication (using credentials as request parameters OR request headers) is possible. But, it is not recommended. Because, login session management (allowing subsequent requests after login) becomes hard. Also, this is not safe as per industry standards. Better will be to do it via username-password authentication using Spring security or use OAuth and JWT tokens.
2). You can use HandlerInterceptor for this requirement. The difference is, filters work at the servlet level and HandlerInterceptor work at the Spring MVC level. So, HandleInterceptor can handle spring context as well. Here is a good comparison stackoverflow.com/a/71227949/4889711
Thank you very much@@GenuineCoder
God
TimeStamp 12.19 Sir, UserdetailsService bean showing error asking to add return statement
timestamp 11.30. Sir, username, password, role all these details are available in the data table. How can we hardcode these details?
Hi! Thank you very, very much. How to get such cool world web icons for @RestController methods? :)
I believe they come with the IntelliJ Ultimate edition. You can try IntelliJ Ultimate trial for free to checkout the latest spring and spring boot features.
bro. Your accent looks very similar to mine.
What about for the maven 😢 i have a hard time fixing the dependency since it uses javas and springboot 3 is using jakartae
I prefer Gradle over Maven due to its more readable syntax, whereas Maven's XML configuration can be overwhelming.
What specific challenge or problem are you experiencing with Jakarta EE, and is it related to upgrading from Spring Boot 2.X to 3.X?
is this doable with mongodb database or it necessites a rational database?
It is doable in any database, including MongoDB. For MongoDB, instead of using Spring Data JPA, Spring Data MongoDB should be used.
i have a question how 403 and 404 error page appears without mapping it or without adding GlobalErrorHandler ?
This is a special feature. Without any java side configuration, you can customize the error pages for specific error codes directly from resources.
"You can also customize the error pages by adding files with names like error.html, 404.html, etc., in the src/main/resources/public/error directory. The file name should match the HTTP status code you want to handle."
Hi sir I am getting Access to local host was denied error
Do you know how can it be resolved!??
Hi, Are you not able to access localhost on browser? If so, double check your spring boot server port.
Please put the actual code of the project into any repo as well
Thanks for the suggestion. Here is the repo link github.com/afsalashyana/Spring-Boot-Tutorials/tree/master/LearnSpringSecurity
can we use Roles as enum it look simple
ENUM is a great idea! Handling role as an enum is definitely possible, and I think is better.
How to handle the situation of invalid credentials?
You can use an "AuthenticationFailureHandler" to handle the invalid credentials. Using this, it is possible to provide customized error messages or even redirect the user to specific error pages.

@@GenuineCoder thank you brother 🙏
bro from kerala
അതെ.
@@GenuineCoder basically iam from A.P I find you from Kerala by your slang
Where is the logic? You showed how to register a user in the database via the rest api, but did not show how to then log in to the server via the rest api by entering the username and password Postman. Because of this, a fairly good tutorial became a waste of time.
he is malayali (from tamilanadu)
Yes, Malayali from Kerala
