I've a problem with the keycloak admin client.
When I try to do :
// Création d'un client Keycloak
Keycloak keycloak = KeycloakBuilder.builder()
.serverUrl(keycloakUrlAuth)
.realm(keycloakRealm)
.grantType(OAuth2Constants.CLIENT_CREDENTIALS)
.clientId(keycloakClientId)
.clientSecret(keycloakClientSecret)
.build();
// Obtention du token d'accès
AccessTokenResponse token = keycloak.tokenManager().getAccessToken();
return token.getToken();
I always get this error :
at [Source: (org.jboss.resteasy.client.jaxrs.internal.ClientResponse$InputStreamWrapper); line: 1, column: 18] (through reference chain: org.keycloak.representations.AccessTokenResponse["access_token"]): javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "access_token" (class org.keycloak.representations.AccessTokenResponse), not marked as ignorable (10 known properties: "tokenType", "notBeforePolicy", "otherClaims", "token", "sessionState", "refreshExpiresIn", "scope", "expiresIn", "refreshToken", "idToken"])

And the jboss-deployment-structure we use (we exclude some modules to be able to use a newer version of jackson - need for openapi) :

I've tried a lot of things.. Changing the versions, exclude dependencies.. but nothing works :(
Could someone help me ?
Thank you
Well, I finally found something that works (but still don't understand why it doesn't work like that).. Here is my solution for now :
First, I've extended de NamingBase to be able to override de names of the fields :
public class CustomNaming extends PropertyNamingStrategies.NamingBase {
public CustomNaming() {
super();
}
@Override
public String translate(String s) {
switch (s) {
case "token":
return "access_token";
case "expiresIn":
return "expires_in";
case "refreshExpiresIn":
return "refresh_expires_in";
case "refreshToken":
return "refreshToken";
case "tokenType":
return "token_type";
case "idToken":
return "id_token";
case "notBeforePolicy":
return "not-before-policy";
case "sessionState":
return "session_state";
case "errorDescription":
return "error_description";
case "errorUri":
return "error_uri";
default:
return s;
}
}
}
Then, I've also extended de ResteasyJackson2Provider to use that customNaming and other properties in the objectMapper :
public class CustomRestEasyJackson2Provider extends ResteasyJackson2Provider {
public CustomRestEasyJackson2Provider() {
super();
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
mapper.setPropertyNamingStrategy(new CustomNaming());
setMapper(mapper);
}
}
And finally, I use it in the KeycloakBuilder :
Keycloak keycloak = KeycloakBuilder.builder()
.serverUrl(keycloakUrlAuth)
.realm(keycloakRealm)
.grantType(OAuth2Constants.CLIENT_CREDENTIALS)
.clientId(keycloakClientId)
.clientSecret(keycloakClientSecret)
.resteasyClient(new ResteasyClientBuilder()
.register(new CustomRestEasyJackson2Provider(), 1000)
.build())
.build();
Like that, it works !
