添加Web套接字支持弹簧数据休息事件

Question

我有弹簧数据休息库，默认发布，更新和删除。 我还实现了一个事件处理程序，现在如何将Web套接字添加到事件处理程序中？

@RepositoryEventHandler(User.class)
@Service
public class UserEventHandler {
    private static final Logger LOG =    LoggerFactory.getLogger(UserEventHandler.class);

   @Autowired
   private SmtpMailSender smtpMailSender;

   @HandleAfterCreate
   public void handleBeforeCreate(User u) {
   }

}

// Repository class
@Transactional
@RepositoryRestResource(path = "users", collectionResourceRel = "users")
public interface UserRepository extends PagingAndSortingRepository<User, String> {

}
