Please reffer to this portion of the documentation. The way you are trying to send a message is totally wrong. I would modify your above class as follows:

@EnableScheduling
@Controller
public class GreetingController {

    @Autowired
    private SimpMessagingTemplate template;

    @Scheduled(fixedRate = 5000)
    public void greeting() {
        Thread.sleep(1000); // simulated delay
        System.out.println("scheduled");
        this.template.convertAndSend("/topic/greetings", "Hello");
    }

}
