我需要以下查询才能转换为条件构建器。

公共类Event扩展BaseModel实现了Serializable {

SMSCommunicationRecipient：

@Table(name = "communication.email_communication_recipient")
public class EmailCommunicationRecipient extends BaseModel implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "email_recipientid_generator")
@SequenceGenerator(name = "email_recipientid_generator", sequenceName = "communication.email_recipient_id_seq", allocationSize = 1)
@Column(name = "email_recipient_id", unique = true, nullable = false)

private String recipientTypeId;
@Column(name = "is_deleted")
private Character isDeleted;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name = "event_id", nullable = false)

}
我已经按如下所示创建了我的条件构建器。
@Entity
@Table(name = "communication.sms_communication_recipient")
public class SMSCommunicationRecipient extends BaseModel implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sms_recipientid_generator")
@SequenceGenerator(name = "sms_recipientid_generator", sequenceName = "communication.sms_recipient_id_seq", allocationSize = 1)
@Column(name = "sms_recipient_id", unique = true, nullable = false)
private Integer smsRecipientId;
@ManyToOne
@JoinColumn(name = "recipient_group_id", referencedColumnName = "reference_data_id")
private CommunicationReferenceData recipientGroupId;
@Column(name = "is_deleted")
private Character isDeleted;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name = "event_id", nullable = false)
private Event event;
}
这将生成以下SQL查询。
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, EmailCommunicationRecipient> joinEmailRecipient = root.join(Event_.emailCommunicationRecipient, JoinType.LEFT);
Join<Event, SMSCommunicationRecipient> joinSMSRecipient = root.join(Event_.smsCommunicationRecipient, JoinType.LEFT);
root.fetch(Event_.emailCommunicationRecipient, JoinType.LEFT);
root.fetch(Event_.smsCommunicationRecipient, JoinType.LEFT);*/
Join<Event, EmailCommunicationRecipient> joinEmailRecipient = (Join<Event, EmailCommunicationRecipient>) root.fetch(Event_.emailCommunicationRecipient, JoinType.LEFT);
//Join<EmailCommunicationRecipient, CommunicationReferenceData> joinEmailRefernce = (Join<EmailCommunicationRecipient, CommunicationReferenceData>) root.fetch(EmailCommunicationRecipient_.recipientGroupId, JoinType.INNER);
Join<Event, SMSCommunicationRecipient> joinSMSRecipient = (Join<Event, SMSCommunicationRecipient>) root.fetch(Event_.smsCommunicationRecipient, JoinType.LEFT);
criteriaQuery.select(root);
criteriaQuery.where(builder.equal(root.get(Event_.eventId), eventId),builder.equal(joinEmailRecipient.get(EmailCommunicationRecipient_.isDeleted), CommunicationConstants.FLAG_N),
builder.equal(joinSMSRecipient.get(SMSCommunicationRecipient_.isDeleted), CommunicationConstants.FLAG_N));
Query query = manager.createQuery(criteriaQuery);
List<Event> eventList = query.getResultList();
Event event = null;
if (null != eventList && !eventList.isEmpty()) {
event = eventList.get(0);
}
我只需要将AND条件应用于左外部JOIN。
如何在“标准构建器”中实现这一目标
