I am using Spring Boot KeyCloak in my application to connect with KeyCloak. However I have a custom success handler which is not being invoked. I am not sure why. here is my code:
SecurityConfiguration.java:
#KeycloakConfiguration
public class SecurityConfiguration extends KeycloakWebSecurityConfigurerAdapter {
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) {
KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
auth.authenticationProvider(keycloakAuthenticationProvider);
}
#Bean
public KeycloakSpringBootConfigResolver keycloakConfigResolver() {
return new KeycloakSpringBootConfigResolver();
}
#Bean
#Primary
#Override
protected KeycloakAuthenticationProcessingFilter keycloakAuthenticationProcessingFilter() throws Exception {
KeycloakAuthenticationProcessingFilter filter = new KeycloakAuthenticationProcessingFilter(authenticationManagerBean());
filter.setSessionAuthenticationStrategy(sessionAuthenticationStrategy());
filter.setAuthenticationSuccessHandler(successHandler());
filter.setAuthenticationFailureHandler(failureHandler());
return filter;
}
#Bean
#Override
protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
}
#Override
protected void configure(HttpSecurity http) throws Exception {
super.configure(http);
http.csrf().disable().authorizeRequests()
.antMatchers("/**").authenticated();
}
#NotNull
#Bean
public KeyCloakAuthSuccessHandler successHandler() {
return new KeyCloakAuthSuccessHandler(new SavedRequestAwareAuthenticationSuccessHandler());
}
#NotNull
#Bean
public KeyCloakAuthFailureHandler failureHandler() {
return new KeyCloakAuthFailureHandler();
}
}
And in my KeyCloakAuthSuccessHandler.java, I have:
#Slf4j
public class KeyCloakAuthSuccessHandler extends KeycloakAuthenticationSuccessHandler {
#Autowired
ObjectMapper mapper;
public KeyCloakAuthSuccessHandler(AuthenticationSuccessHandler fallback) {
super(fallback);
}
#Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
throws IOException, ServletException {
log.error("inside success handler");
if (authentication.getPrincipal() instanceof KeycloakPrincipal) {
AccessToken token = ((KeycloakPrincipal<?>) authentication.getPrincipal()).getKeycloakSecurityContext().getToken();
// do other stuff
}
}
}
The above code doesn't invoked the success handler however a similar failure handler is working and getting invoked.
As discussed over the comments, this is because the success handler is not invoked during non-interactive(non-human ways - bearer/basic) login of Keycloak. If you want to invoke success handler each time irrespective of the way of login, write a custom KeycloakAuthencticationProcessingFilter by extending the same and change this line from the original one by over-riding it.
A rough example will look like:
public class CustomKeycloakAuthenticationProcessingFilter extends KeycloakAuthenticationProcessingFilter {
public CustomKeycloakAuthenticationProcessingFilter(AuthenticationManager authenticationManager) {
super(authenticationManager);
}
public CustomKeycloakAuthenticationProcessingFilter(AuthenticationManager authenticationManager, RequestMatcher requiresAuthenticationRequestMatcher) {
super(authenticationManager, requiresAuthenticationRequestMatcher);
}
#Override
protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain,
Authentication authResult) throws IOException, ServletException {
// Line of importance down here
if (authResult instanceof KeycloakAuthenticationToken) {
super.successfulAuthentication(request, response, chain, authResult);
return;
}
// whatever spring-boot-keycloak does copy paste here
}
}
I think you have to write your own KeycloakAuthenticationProcessingFilter using your KeyCloakAuthSuccessHandler.
https://github.com/keycloak/keycloak/blob/main/adapters/oidc/spring-security/src/main/java/org/keycloak/adapters/springsecurity/filter/KeycloakAuthenticationProcessingFilter.java
You can't inject your KeyCloakAuthSuccessHandler.
I have the following spring websocket stomp client:
var client = new StandardWebSocketClient();
WebSocketStompClient stompClient = new WebSocketStompClient(client);
MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
converter.setObjectMapper(mapper);
stompClient.setMessageConverter(converter);
StompSessionHandler sessionHandler = new StompSessionHandler() {
#Override
public void afterConnected(final StompSession session, final StompHeaders connectedHeaders) {
session.subscribe("/topic/senha", this);
}
...
#Override
public void handleFrame(final StompHeaders headers, final Object payload) {
//get notification here
}
};
stompClient.connect(uri.toString(), sessionHandler);
Server:
#Configuration
#EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
#Override
public void configureMessageBroker(final MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
#Override
public void registerStompEndpoints(final StompEndpointRegistry registry) {
registry.addEndpoint("/ws");
}
}
I get notified in handleFrame about new messages.
But the topic has messages in it's history.
I want to fetch the last message/state from the topic when connected. How to do it?
I use keycloak as a Central Authentication Service for (single sign on/out) feature.
I have app1, app2, app3. app1 and app2 is monothetic application. app3 use spring session (use redis as session store),
All feature work fine. But I use the back channel to logout for SSO(single sign out) feature, that's works for app1 and app2. But it not work for this app3.
I wonder how to back channel logout application that use spring session
The keycloak admin url invoke when client user send a logout request to it.I find that KeycloakAutoConfiguration#getKeycloakContainerCustomizer() inject WebServerFactoryCustomizer for add KeycloakAuthenticatorValve, and that Valve
use CatalinaUserSessionManagement, but it have not any info about redis as its session store. So I add a customizer for enhence the Valve.
first i set the order of the autoconfig, because extra customizer must be callback after it.

This mqtt subscriber code works fine. I can easily subscribe to messages which are published at broker.hivemq.com with respective topic.
public class AccelerometerSubscriber implements MqttCallback,
IMqttActionListener {
public static void main(String[] args) throws MqttException {
int QUALITY_OF_SERVICE = 2;
MqttClient client=new MqttClient("tcp://broker.hivemq.com:1883",
MqttClient.generateClientId());
client.setCallback( new SimpleMqttCallBack() );
client.connect();
System.out.println("Subscribing ....");
client.subscribe("MQTT Examples"); }
System.out.println("some action"); //------------right here--------------
public void connectionLost(Throwable throwable) {
System.out.println("Connection to MQTT broker lost!"); }
public void messageArrived(String s, MqttMessage mqttMessage) throws Exception {
System.out.println("Message received:\n\t"+ new String(mqttMessage.getPayload()) );
}
public void deliveryComplete(IMqttDeliveryToken iMqttDeliveryToken) {
// not used in this example
}}
Now I want to perform action only when a message is received. I'm unable to do that.
You have a class (AccelerometerSubscriber) that implements the interface MqttCallback, use an instance of it instead of doing client.setCallback( new SimpleMqttCallBack() );
public class AccelerometerSubscriber implements MqttCallback, IMqttActionListener {
public static void main(String[] args) throws MqttException {
AccelerometerSubscriber as = new AccelerometerSubscriber();
int QUALITY_OF_SERVICE = 2;
MqttClient client = new MqttClient("tcp://broker.hivemq.com:1883", MqttClient.generateClientId());
client.setCallback(as);
client.connect();
System.out.println("Subscribing ....");
client.subscribe("MQTT Examples");
}
#Override
public void connectionLost(Throwable throwable) {
System.out.println("Connection to MQTT broker lost!");
}
#Override
public void messageArrived(String s, MqttMessage mqttMessage) throws Exception {
//message is received is here!!!
System.out.println("Message received:\n\t" + new String(mqttMessage.getPayload()));
}
#Override
public void deliveryComplete(IMqttDeliveryToken iMqttDeliveryToken) {
System.out.println("deliveryComplete");
}
#Override
public void onFailure(IMqttToken arg0, Throwable arg1) {
System.out.println("onFailure");
}
#Override
public void onSuccess(IMqttToken arg0) {
System.out.println("onSuccess");
}
}
I use the twitter4j query interface to filter tweets http://twitter4j.org/javadoc/twitter4j/Query.html. But the twitter spout in https://github.com/nathanmarz/storm-starter/blob/master/src/jvm/storm/starter/spout/TwitterSampleSpout.java:43 uses queue.offer(status). I don't have a reference to Status, how do I integrate these API(s) to process live tweets.
This is what we have been using successfully to filter tweets:
public void open(Map conf, TopologyContext context, SpoutOutputCollector collector) {
queue = new LinkedBlockingQueue<Status>(1000);
_collector = collector;
StatusListener listener = new StatusListener() {
public void onStatus(Status status) {
queue.offer(status);
}
public void onDeletionNotice(StatusDeletionNotice sdn) {
}
public void onTrackLimitationNotice(int i) {
}
public void onScrubGeo(long l, long l1) {
}
public void onException(Exception e) {
}
};
TwitterStreamFactory fact = new TwitterStreamFactory(new ConfigurationBuilder().setUser(_username).setPassword(_pwd).build());
_twitterStream = fact.getInstance();
_twitterStream.addListener(listener);
_twitterStream.filter(new FilterQuery().track(TERMS_TO_TRACK).setIncludeEntities(true));
}
