我不是“条件”构建器中的以下转换查询。
select * from communication.event_master event inner join communication.email_communication_recipient email
打开event.event_id = email.event_id内部加入communication.sms_communication_recipient短信 开启event.event_id = sms.event_id
代码：
@SuppressWarnings("unchecked")
@Override
public Event retrieveCommunicationEvent(Integer eventId) throws CommunicationException {
List<Predicate> conditions = new ArrayList<>();
CriteriaBuilder builder = manager.getCriteriaBuilder();
CriteriaQuery<Event> criteriaQuery = builder.createQuery(Event.class);
Root<Event> root = criteriaQuery.from(Event.class);
//Join<Event, EmailTemplateMaster> emailTemplateMaster = root.join(Event_.emailTemplateMaster, JoinType.INNER);
/*Fetch<Event, EmailCommunicationRecipient> fetchEmailRecipient = root.fetch(Event_.emailCommunicationRecipient, JoinType.LEFT);
Fetch<Event, SMSCommunicationRecipient> fetchSMSRecipient = root.fetch(Event_.smsCommunicationRecipient, JoinType.LEFT);*/
//root.fetch(Event_.eventTrigger,JoinType.LEFT);
SetJoin<Event, EmailCommunicationRecipient> fetchEmailRecipient = root.join(Event_.emailCommunicationRecipient, JoinType.LEFT);
SetJoin<Event, SMSCommunicationRecipient> fetchSMSRecipient = root.join(Event_.smsCommunicationRecipient, JoinType.LEFT);
conditions.add(builder.equal(root.get(Event_.eventId), eventId));
conditions.add(builder.equal(fetchEmailRecipient.get(EmailCommunicationRecipient_.isDeleted), CommunicationConstants.FLAG_N));

List<Event> eventList = query.getResultList();
Event event = null;
if (null != eventList && !eventList.isEmpty()) {
event = eventList.get(0);
