oauth 2.0 – Spring Boot + Security OAuth2.0 Client with Custom Provider

Finally, the problem is solved. I just need to configure the jwk URI which should be provided by the Auth provider.
Below the final configuration for customer Auth Provider.

spring.security.oauth2.client.registration.xxxxxxxxx.client-id=XXXXXXXXXX
spring.security.oauth2.client.registration.xxxxxxxxx.client-secret=XXXXXXXXXX
spring.security.oauth2.client.registration.xxxxxxxxx.scope=openid
spring.security.oauth2.client.registration.xxxxxxxxx.redirect-uri-template=http://localhost:8080/login/oauth2/code/xxxxxxxxx
spring.security.oauth2.client.registration.xxxxxxxxx.client-name=xxxxxxxxx
spring.security.oauth2.client.registration.xxxxxxxxx.provider=xxxxxxxxx
spring.security.oauth2.client.registration.xxxxxxxxx.client-authentication-method=basic
spring.security.oauth2.client.registration.xxxxxxxxx.authorization-grant-type=authorization_code

spring.security.oauth2.client.provider.xxxxxxxxx.authorization-uri=https://api.xxxxxxxxx.com/authorize
spring.security.oauth2.client.provider.xxxxxxxxx.token-uri=https://api.xxxxxxxxx.com/token
spring.security.oauth2.client.provider.xxxxxxxxx.user-info-uri=https://api.xxxxxxxxx.com/userinfo?schema=openid
spring.security.oauth2.client.provider.xxxxxxxxx.user-name-attribute=name
spring.security.oauth2.client.provider.xxxxxxxxx.user-info-authentication-method=header
spring.security.oauth2.client.provider.xxxxxxxxx.jwk-set-uri=https://api.xxxxxxxxx.com/jwks

Thanks

When you receive JWT in client application, you need to verify the signature of JWT. To verify the signature you need public key of Auth provider. As per OAuth specifications, Auth provider can expose the public key through a URI and client can use this URI to get the public key to validate the JWT. This is what is missing in your configuration.
