Hi Basant, this is an awesome explanation and detailed video on how to set up and use it with microservices. I really njoyed it and i would try it as well. Please keep making such videos. Basant tame jaha bhi karucha, bahut hi bhala kama. We will always support and encourage you.
Hi Java Techie, this demo is really good and made me clear in understanding in some parts. Please refer me if you have a demo with Spring MVC (Non-Boot) application
@Java Techie I am getting below error Client 'myclient' doesn't have secret available failed to turn code into token status from server: 400 {"error":"invalid_client","error_description":"Invalid client credentials"} In response I am getting login page [html back] Can anyone help pls
I tried multiple times...I am able to get token from keyclock but while accessing rest points this error is coming I tried with keyclock 15.* & 19.* but same error in both versions Tried with Spring boot version 2.5.* &2.7.3 Java 11 & latest eclipse 2022 release
But what if my application have a sign up section and i want users to be created from my application in that case how keycloak will get those data? And can keycloak use my database instead of its self?
@@GauravSharma-ry5qf sorry i misunderstood your question. Why will you use keycloal if you want to maintain user credentials with your own ? What do you understand about 3rd party identity providers? Usually you will get the options to register a user in the keycloal user interface itself so the user can sign up from there
@@Javatechie ok , but after exploration I got know that Oauth2 mainly used for Authorization, so for authentication if we have separate service and for the Authorization only we want to use that , so how we can leverage that ?
Hi Basant, I am trying to achieve the same in Spring MVC project, unable to find any documentation for the same. Followed the official one but it is directly opening the controller get mapping page instead of asking for credentials. Please help
Please make video for spring boot and mysql with keycloak embedded project I need only automatically create database and stored data for keycloak clients in table .
Hi Java Techie, This video is very informative. I have one spring boot REST API application which has Login and Signup API and other APIs. I need to have Authorization server, Resource server in this same application using JWT. This way I can save the resources instead of separate server deployment. Can you please end to end flow using Spring Boot 3, Spring Security, Spring Boot starter Authorization server and JWT ? It would be very helpful
Hey Java Techie, i have one doubt. how this keycloak and openid works with microservice architecture where one microservices is calling another microservice. so how to authenticate during this call.
Hi java techie I love your tutorial videos. However do you have a video about applying security Jwt without using websecuritywebconfigurer since it was deprecated in spring boot 2.7.0 . Or planning to make a new video about it?
Hii sir, I had seen the video but i have a doubt i.e you are using role based authority in a single microservice class if I use api gateway how to use role based authority
Is it possible to implement form based and jwt token based authentication in a single app. Currently i implemented spring oauth2 based keycloak sso implementation it works fine in browser.but when i hit the endpoints in postman it return keycloak login page as response
@@Javatechie I meant using Keycloak. In keycloak console you are manually adding users. But my application already having user in user table how can i integrate keycloak?
Thanks Basant for this video. Its really excellent. I have a question. At present we are generating the token in the postman and testing the APIs. From GUI, whenever a user logs in as an admin/user, then how does a token gets generated dynamically in the spring boot and calls the respective API. ? Please answer my question. God bless you :)
@@Javatechie sharing employees information is very crucial and this is crucial authentication info that is to be considered carefully. Which companies have implemented keycloak?
I´m using Spring Tool Suite 4-4 with Keycloak 20.0.2.

Do we always hard code the user and roles in spring boot application? Is there any other way to provide those information at method level (instead of hard coding)
Basant, Again i have gone through your video. One doubt i have. My SecurityConfig class is not getting compiled. I am getting error in "KeycloakWebSecurityConfigurerAdapter". After clicking cntrl+shift+o in my eclipse its still showing red color. I am using jdk 17. May be the code is not supporting for java 17. can you guide me where to get the security config class for openid. ? You are blessed by God by having good intelligence by gaining good knowledge. Thanks for all God bless you..
Hey Java Techie,
I would love to see Keycloak integration with a microservice and also if possible end to end with a frontend as well.
