在具有最大日期的值之间通过最大不同来查找hql中的有序列表

Question

我在postgres中有一张表

CREATE TABLE employer_visit(
  employer_id                     INTEGER REFERENCES employer,
  visit_counter                   INTEGER NOT NULL, -- counter on current date
  visit_before_date_total_counter INTEGER NOT NULL, -- total, since service has started
  date                            DATE,
  PRIMARY KEY(employer_id, date)
);

我需要通过过去30天的访问找到最佳雇主 - （最后一条记录中visit_before_date_total_counter与30天前最后一条记录之间的差异employer_visit的有序列表）

我试过这个hql查询

Query<EmployerVisit> query = getSession().createQuery(
    "SELECT ev FROM EmployerVisit ev " +
        "WHERE ev.employerVisitId.date = (SELECT MAX (groupedEv.employerVisitId.date) FROM EmployerVisit groupedEv " +
        "WHERE groupedEv.employerVisitId.employerId = ev.employerVisitId.employerId) " +
        "AND " +
        "ev.employerVisitId.date = (SELECT MAX (groupedEv2.employerVisitId.date) < :date FROM EmployerVisit groupedEv2 " +
        "WHERE groupedEv2.employerVisitId.employerId = ev.employerVisitId.employerId) " +
        "ORDER BY (groupedEv.visitCounter + groupedEv.visitBeforeDateTotalCounter) - (groupedEv2.visitCounter + groupedEv2.visitBeforeDateTotalCounter) DESC"
).setMaxResults(size).setParameter("date", calendar.getTime());

但它落在了

Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Invalid path: 'groupedEv.visitCounter' 

在groupedEv

之后，ORDER BY表格不存在

在hibernate中可以对这种情况使用depricated SqlQuery但是我更喜欢hql，请帮助，谢谢。

UPDATE！ - 没有setter和getter的Entity和EmbeddedId类

@Entity
@Table(name = "employer_visit")
public class EmployerVisit {

  @EmbeddedId
  private EmployerVisitId employerVisitId;

  @Column(name = "visit_counter")
  private Integer visitCounter;

  @Column(name = "visit_before_date_total_counter")
  private Integer visitBeforeDateTotalCounter;

  public EmployerVisit() {
    employerVisitId = new EmployerVisitId();
    visitCounter = 0;
    visitBeforeDateTotalCounter = 0;
  }
}

@Embeddable
public class EmployerVisitId implements Serializable {

  @Column(name = "employer_id")
  private Integer employerId;

  @Column(name = "date")
  private Date date;

  public EmployerVisitId() {
  }
}
