Integrating Auth0 in RESTEasy APIs


I have SPA + API(RestEasy). And I would like to integrate auth0. Almost I have clarity on integrating auth0 in SPA. But for API(RestEasy), I didnt find any suitable sample SDK. All the example is with spring boot /spring boot security.

I would like to create a resource server(which RESTEasy API’s) for this. And when these API’s are called from SPA.Then I would like to authenticate at API end. Is there any sample application or SDK where it suits my requirement ?
