[keycloak-user] Add new filter for RealmResourceProvider

Hello, I have some customized provider implements RealmResourceProvider, something likes this: public class UserProvider implements RealmResourceProvider { ... @Path("/{username}/pre-authentication") @PUT @Produces(MediaType.APPLICATION_JSON) public Response validateAuthenticationRequest(@PathParam("username") String username, @HeaderParam("Authorization") String authorization) { } ... } Everytime I put a rest call to this provider, and I can see 'keycloakSessionServletFilter' is already passed. My question is: Can I add extra filter after 'keycloakSessionServletFilter'? and How? Thanks! Stone
