[keycloak-user] Convert Bearer Token to Principal (Java+Spring+WS)

Hi! I'm trying to secure a websocket endpoint using the recommendations from spring's documentation at https://github.com/spring-projects/spring-framework/blob/master/src/docs/... I can get the Bearer token in the Stomp Message Header but I don't know how to convert it to a Principal. Is there a way to actually do this? Here's a code snippet of what's expected: if (StompCommand.CONNECT.equals(accessor.getCommand())) { Authentication user = ... ; // access authentication header(s) accessor.setUser(user); } -- Adrian E.
