### Question:
AlertDefinitionDAO { @Transactional public void create(AlertDefinitionEntity alertDefinition) throws AmbariException { EntityManager entityManager = entityManagerProvider.get(); entityManager.persist(alertDefinition); AlertGroupEntity group = dispatchDao.findDefaultServiceGroup(alertDefinition.getClusterId(), alertDefinition.getServiceName()); if (null == group) { String serviceName = alertDefinition.getServiceName(); group = dispatchDao.createDefaultGroup(alertDefinition.getClusterId(), serviceName); } group.addAlertDefinition(alertDefinition); AlertGroupsUpdateEvent alertGroupsUpdateEvent = new AlertGroupsUpdateEvent(Collections.singletonList( new AlertGroupUpdate(group)), UpdateEventType.UPDATE); STOMPUpdatePublisher.publish(alertGroupsUpdateEvent); dispatchDao.merge(group); AlertDefinition coerced = alertDefinitionFactory.coerce(alertDefinition); if (null != coerced) { AlertDefinitionRegistrationEvent event = new AlertDefinitionRegistrationEvent( alertDefinition.getClusterId(), coerced); eventPublisher.publish(event); } else { LOG.warn("Unable to broadcast alert registration event for {}", alertDefinition.getDefinitionName()); } entityManager.refresh(alertDefinition); }  @RequiresSession AlertDefinitionEntity findById(long definitionId); @RequiresSession AlertDefinitionEntity findByName(long clusterId, String definitionName); @RequiresSession List<AlertDefinitionEntity> findAll(); @RequiresSession List<AlertDefinitionEntity> findAll(long clusterId); @RequiresSession List<AlertDefinitionEntity> findAllEnabled(long clusterId); @RequiresSession List<AlertDefinitionEntity> findByIds(List<Long> definitionIds); @RequiresSession List<AlertDefinitionEntity> findByService(long clusterId,
      String serviceName); @RequiresSession List<AlertDefinitionEntity> findByServiceMaster(long clusterId,
