Spring Boot Web Socket RabbitMQ not available

Question

I have simple spring boot app with web socket configuration.

When i run my app with SimpleBroker(provided by spring) everything works fine, but when i want to use rabbitmq instead of SimpleBroker, i have some problems, my broker is "not available"

@Configuration
@EnableWebSocketMessageBroker
open class WebSocketConfig : ILogging by LoggingImp<WebSocketConfig>(), 
WebSocketMessageBrokerConfigurer {

@Autowired
private lateinit var env: Environment

override fun registerStompEndpoints(registry: StompEndpointRegistry) {
    registry.addEndpoint("/hig").setAllowedOrigins("*").withSockJS()
}

override fun configureMessageBroker(registry: MessageBrokerRegistry) {
    registry.setApplicationDestinationPrefixes("/app")
    val host = env.getProperty("spring.rabbitmq.host")!!
    val port = env.getProperty("spring.rabbitmq.port")!!.toInt()
    val login = env.getProperty("spring.rabbitmq.username")!!
    val pass = env.getProperty("spring.rabbitmq.password")!!
    log.debug("webSocket=$host, $port, $login, $pass")
//        registry.enableSimpleBroker("/chat")
    registry.enableStompBrokerRelay("/chat")
            .setRelayHost(host)
            .setRelayPort(port)
            .setClientLogin(login)
            .setClientPasscode(pass)
            .setAutoStartup(true)
            .setSystemHeartbeatReceiveInterval(10000)
            .setSystemHeartbeatSendInterval(10000)
    }

}

response from WebSocketMessageBrokerStats:

For client i'm using angular 5

When i'm using registry.enableSimpleBroker("/chat") everything works fine

When i enable registry.enableStompBrokerRelay("/chat")... i'm getting:

message:Broker not available. content-length:0

Answer 1

You are trying to connect using stomp protocol on a rabbitmq which doesn't run the stomp adapter. Run:

rabbitmq-plugins enable rabbitmq_stomp

to enable stomp.

Also, you are connecting to the port 5672 which is the amqp protocol / adapter. This is why you have this stompCommand=ERROR, nativeHeaders={message=[Broker not available.]}. Once enabled, the stomp adapter will by default listen on tcp/61613.
