Okay, back to the JWTAuthenticationFilter which will filter out requests that have JWT as header and translate that to something Spring Security can understand using the methods from the Token Provider we just created. They have many-to-many relationship. * AuthenticationManager Add ZUUL, Eureka client dependency to it. Given a well-formed JWT, Resource Server will: Validate its signature against a public key obtained from the jwks_url endpoint during startup and matched against the JWT, Validate the JWTs exp and nbf timestamps and the JWTs iss claim, and.
