How does Spring Security validate JWT tokens in an OAuth2 Resource Server?
Spring Security fetches the Authorization Server's public keys (JWK Set) from its jwks-uri, verifies the incoming JWT's signature against them, and validates standard claims (iss, aud, exp). Configure via spring.security.oauth2.resourceserver.jwt.jwk-set-uri.
