public class Sender {    Logger log = Loggerfactory.getlogger (Sender.class);    @Autowired    private kafkatemplate kafkatemplate;    public void SendMessage (String topic, event event) {        Listenablefuture<sendresult<integer, string>> Future = kafkatemplate.send (topic, message);        Future.addcallback (New Listenablefuturecallback<sendresult<integer, string>> () {            @Override            public void onsuccess (Sendresult<integer, string> result) {                log.info ("Send success {}", Result.getproducerrecord (). value ());                         }            @Override public            void OnFailure (Throwable ex) {                Log.warn ("Send fail {}", Ex.getmessage ());            }        );    }}
