This handler is part of the light-rest-4j which is built on top of light-4j but focused on RESTful API only.
It supports OAuth2 with JWT token distributed verification and can be extended to other authentication and authorization approaches.
This is the handler that is injected during server start up if security.json enableVerifyJwt is true. It does further scope verification if enableVerifyScope is true against swagger specification.
Distributed JWT verification
Unlike simple web token, the resource server has to contact Authorization server to validate the bearer token. JWT can be verified by resource server as long as the token signing certificate is available at resource server.
