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.

I have multiple virtual hosts each with a request queue and a response queue. These virtual hosts serve different clients. The names for the request queue and the response queue remain the same across the virtual hosts.
I have created a SimpleRoutingConnectionFactory with the clientName()+"ConnectionFactory" as the lookup key and a corresponding CachingConnectionFactory as the value in the map. I'm able to publish message to the request queues by binding and the RabbitTemplate to a virtual host before convertAndSend and then unbinding it.
I'm not able to consume messages from the response queues from different virtual hosts. I have created a SimpleRabbitListenerContainerFactory for each client. I implemented RabbitListenerConfigurer and registered a SimpleRabbitListenerEndpoint for each SimpleRabbitListenerContainerFactory. I also set the connectionFactory on each SimpleRabbitListenerContainerFactory as the client's CachingConnectionFactory.

However, I get org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer: Failed to check/redeclare auto-delete queue(s). java.lang.IllegalStateException: Cannot determine target ConnectionFactory for lookup key [null]
I'm not able to figure out whats causing this as I'm not using the SimpleRoutingConnectionFactory for message consumption at all.

EDIT2:
I used the routingConnectionFactory with every listener and used the setLookUpKeyQualifier. No more exceptions but, the listeners don't seem to be doing anything i.e., the queues are not being listened to.

There is something very strange going on; [null] implies that when we call getRoutingLookupKey() the cf is not a routing cf but when we call getConnectionFactory() it is.
It's not obvious how that can happen. Perhaps you can figure out why in a debugger?
One solution would be to inject the routing cf and use setLookupKeyQualifier(...).
The lookup key will then be clientId[queueName].
I initialized my twilio client in the code below but I am getting an error
Unable to establish connection to Twilio Sync service
My code:

ChatClient.Properties props =

.setRegion("us1")
.createProperties();
this.buildListener = listener;
//Toast.makeText(context,"++-==++",Toast.LENGTH_LONG).show();
ChatClient.create(context.getApplicationContext(),
token,
props,
new CallbackListener<ChatClient>()
{
#Override
public void onSuccess(ChatClient chatClient) {

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

}
#Override

I'm working on Spring Boot application with configured SSO/OAuth2 security.
Authentication works fine for my rest controllers and now I need to secure my Apache Camel route with a rest endpoint.
As I understand there are several ways how to do it:
By adding auth processor to my route
By adding policy (SpringSecurityAuthorizationPolicy) to my route
By handlers option to jetty endpoint
I'm trying to do it by adding new auth processor to my rest endpoint but I stuck on this exception:
org.springframework.security.oauth2.common.exceptions.OAuth2Exception:
No AuthenticationProvider found for
org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationToken
During debugging I see that org.springframework.security.authentication.ProviderManager.getProviders() contains only one provider AnonymousAuthenticationProvider so probably I have to register appropriate provider...
Can someone help me to find the right way to solve this problem please?

As a final solution I decided to use Spring Boot embedded servlet container instead of Apache Camel rest component. So it could be easily secured by Spring Security. This could be done by creating additional beans:
#Bean
public ServletRegistrationBean servletRegistrationBean() {
SpringServerServlet serverServlet = new SpringServerServlet();
ServletRegistrationBean regBean = new ServletRegistrationBean(serverServlet, "/camel/*");
Map<String, String> params = new HashMap<>();
params.put("org.restlet.component", "restletComponent");
regBean.setInitParameters(params);
return regBean;
}
#Bean
public Component restletComponent() {
return new Component();
}
#Bean
public RestletComponent restletComponentService() {
return new RestletComponent(restletComponent());
}
