Start up by running
mvn spring-boot:run
The code does not have any external dependencies and should start up cleanly. If you are
interested in using RabbitMQ as the external broker to work with Websockets, then the change should be to bk.tailfile.config.WebSocketDefaultConfig class:
// config.enableStompBrokerRelay("/topic/", "/queue/");
config.enableSimpleBroker("/topic/", "/queue/");
TO:
config.enableStompBrokerRelay("/topic/", "/queue/");
// config.enableSimpleBroker("/topic/", "/queue/");
Just bring up an instance of RabbitMQ and it should work cleanly.
