I am using spring boot with angular for azure ad authentication. In angular i have used Microsoft adal library for authentication. From that I am getting an access token, and passing as header with request to spring boot app. But When i am retrieving SecurityContext object, i am getting anonymous user.
Now how does spring security knows about this user login. Do i need to explicitly do any code for this to get done?
Configure properly azure-spring-boot (ad client id and secret) and then in WebSecurityConfigurerAdapter filter your requests with AADAuthenticationFilter. Check out a sample here.

I'm developing an app.
Front/bff/api.
I'm using an open id provider that allows to check token remotely.
The bff intercepts the front requests and sends them to the API with the jwt token in the header.
The api should ask the open ip provider if the token is correct (but remotely, not using the offline mode with the public key ).
The api is a spring boot 3.0.1 project.
How to configure security in spring boot 3.0.1 to do that check?
Thank you in advance.
You do that with access-token introspection. In spring-security conf, that means using opaqueToken() instead of jwt() (the first configures a resource-server with introspection and the second with a JWT decoder).
Be aware that token introspection is far less efficient than using a JWT decoder as a request is sent to the authorization-server for each and every request to a resource-server. Tutorial there.
i am currently working on a project where my backend uses Spring Boot, Spring security + keycloak and runs on localhost:8081.
My frontend (svelte) runs on http://127.0.0.1:5173/ and the url http://127.0.0.1:5173/products needs to access data from localhost:8081/products (which needs a login) but the login page from keycloak doesnt appear.
In other words, what i am trying to achieve:
I want that the url http://127.0.0.1:5173/products redirects to localhost:8081/products which redirects to keycloak login page and after a successfull login i want to return to http://127.0.0.1:5173/products where i will be able to see the data.
is there an elegant solution to this problem? Im really stuck on this problem and this is one of my first projects.
Thanks in advance!!
Some OAuth2 wording:
Keycloak is an authorization-server (OIDC complient)
Svelte app is a client
Spring REST API is a resource-server
Ensure that a "public" client is declared in Keycloak.
Configure your Svelte client with an existing OIDC lib (component) of your choice to:
use the "public" client deckared in Keycloak
authenticate users against Keycloak (socket is not the same as spring API)
add an authorization header with a JWT access-token retrieved from Keycloak (when issuing requests to your secured REST endpoints)
Configure Spring API as a secured resource-server with a JWT decoder.
You can refer to this article for configuring Keycloak and resource-server with JWT access-tokens.
I registered the app in an azure ad, and I have application id(client id) and directory id (tenant id), and secret key.
using this need to generate the jwt token in the azure ad and need to validate that token.
once the token generate need to call the third-party API's using that token in spring boot application.
please provide some example
To achieve the above requirement. You can take Reference of this Post to call the third-party Api using the JWT token using spring boot application.
In the above, there is tutorial they have built a Spring Boot Application that supports Token based Authentication with JWT. Please refer the section How to configure Spring Security to work with JWT that might be solution of requirement.
I am working on a Spring Boot application where existing user authentication is based on Oauth2 with 2FA. Now, I would like to call the APIs in my application from the third-party client as well, say from another service.
Basically, I would like to develop one auth API, where on providing a valid client name, valid API key, and API secret, the client will get an auth token, which will be valid for say 1 hour. Then this auth token can be passed in all successive API invocation until the token gets expired.
I found a few articles here:
a. Securing Spring Boot API with API key and secret
b. How to secure spring Boot API with API key and secret
c. how to implement api key secure in spring boot?
d. How to config multiple level authentication for spring boot RESTful web service?
But, I am not getting any concrete idea regarding, how to achieve this.
Could you please suggest how can I achieve this? Thanks
I have read some articles for Keycloak spring implementation (eg: easily-secure-your-spring-boot-applications-with-keycloak) but no one mention how to use with JWT.
I have created zuul api gateway and add Keycloak adapter as described in the previously linked article. That's ok, but I want to use JWT with keycloak.
Mentioned elsewhere set the client access type to bearer-only and the session strategy to NullAuthenticatedSessionStrategy. That's enough or need something else for JWT?
So my questions:
How do I configure client on Keycloak admin for JWT?
How do I configure Keycloak in backend config file for JWT?
How do I configure Keycloak adapter for JWT?
How do I pass user info to microservice? Create filter in gateway? But how I get user info from request?
Keycloak access token is a JWT. It is a JSON and each field in that JSON is called a claim. By default, logged in username is returned in a claim named “preferred_username” in access token. Spring Security OAuth2 Resource Server expects username in a claim named “user_name”. So, you need to create mapper to map logged in username to a new claim named user_name.
In order to provide access to client (micro-service), respective role needs to be assigned/mapped to user.
In your spring boot application, then you need to configure connection to keycloak server, providing, auth url, token url, scope, grant-type, client-id and client-secret.
Afterthat, your app be able to parse JWT token, you need to create some JwtAccessTokenCustomizer. This class should extend DefaultAccessTokenConverter and implement JwtAccessTokenConverterConfigurer classes. The main logic lays in public OAuth2Authentication extractAuthentication(Map<String, ?> tokenMap) method.
Then you need to configure OAuth2 Resource Server to provide access for other micro services. For that you define here - Oauth2RestTemplate Bean.
And in the end, secure your REST API, via the standard configuration Component.
So, you can see that, it is a large work, and couldn't be described with code, show some of your work, divide it to the chunk, and ask interesting your questions.
