有没有Eclipselink替代Hibernate @where注解?我的Entity类在Hibernate中

@Table(name = "entity_definition")
public class EntityDefinition implements Serializable {

  /**
   *
   */
  private static final long serialVersionUID = 1L;
  @Id
  @Column(name = "\"entity_id\"", nullable = false)
  private Integer entityId;

  @OneToMany(mappedBy = "entityId", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
  @Where(clause = "ep_exp_dt >= now()")
  private Set<EntityProvider> entityProvider;

或者如何使用CriteriaBuilder来执行此操作

CriteriaBuilder cb = entityManager.getCriteriaBuilder();
        CriteriaQuery<EntityDefinition> cq = cb.createQuery(EntityDefinition.class);   
        Root<EntityDefinition> ed = cq.from(EntityDefinition.class);       

        ParameterExpression<Date> paramCurrentDate = cb.parameter(Date.class);
        final Predicate predicateEDCurrDate = cb.greaterThanOrEqualTo(ed.get("edExpDt"), paramCurrentDate);

        ParameterExpression<String> paramEntityName = cb.parameter(String.class);
        final Predicate predicateEntityName = cb.equal(ed.get("entityNm"), paramEntityName);

        cq.select(ed).where(cb.and(predicateEntityName, predicateEDCurrDate));
        TypedQuery<EntityDefinition> tQuery = entityManager.createQuery( cq );
        tQuery.setParameter( paramEntityName, entityNm.toUpperCase() );
        tQuery.setParameter( paramCurrentDate, Date.valueOf(LocalDate.now()));
        
        return tQuery.getSingleResult();

感谢你的帮助。

你可以使用@org.eclipse.persistence.annotations.
@Entity @AdditionalCriteria(“isActive ='false'”)公共类产品{ //...@列私有布尔值isActive;}
https://www.eclipse.org/eclipselink/documentation/2.7/jpa/extensions/annotations_ref.htm#additionalcriteria
