How to get authenticationProvider with new azure-sdk-for-java OAuth2AuthorizedClient

[mattstrain]

With the azure-sdk-for-java you can now obtain authorisation tokens for clients and on behalf of users as part of the API like this.

public String callGraph(@RegisteredOAuth2AuthorizedClient("graph") OAuth2AuthorizedClient graph) {
  
if (null != graph) {
            String body = webClient
                .get()
                .uri(GRAPH_ME_ENDPOINT)
                .attributes(oauth2AuthorizedClient(graph))
                .retrieve()
                .bodyToMono(String.class)
                .block();
            LOGGER.info("Response from Graph: {}", body);
            return "Graph response " + (null != body ? "success." : "failed.");
        } else {
            return "Graph response failed.";
        }
}

However all the samples there don't use this API and just call the api directly using a webclient. See azure-spring-boot-sample-active-directory-resource-server-obo

How do we build a GraphService client using this API from a OAuth2AuthorizedClient object?

Hey @mattstrain ,
Thanks for reaching out. Right now OBO is not supported by azure identity java and we have an issue tracking this here.

The workarounds include using MSAL or relying on frameworks/libraries (like spring) to "trade" the token for your application. Once this is done, you can derive from BaseAuthenticationProvider to pass the new token to the graph client.
Let me know if you have further questions.

Great thanks for the update. I'll keep an eye on that issue for updates.
