spring - @SqlResultSetMapping 使用导致架构验证问题

Question

我必须提取数据用于统计目的。我创建了一个本地查询并使用了 @SqlResultSetMapping将结果集映射到一个对象。
Hibernate 需要将这个类(Elaboration)声明为 @Entity但不是表格，我不想要表格，因为我只需要在需要时动态提取数据。

代码工作正常，但 gitlab 管道在验证期间失败

schemaManagementException: Schema-validation: missing table [elaboration].

到目前为止，我的代码是:

    SqlResultSetMapping(name="ValueMapping",
                     classes={
                       @ConstructorResult(
                         targetClass=Elaboration.class,
                         columns={
                           @ColumnResult(name="areadesc", type=String.class),
                           @ColumnResult(name="subsectordesc", type=String.class),
                           @ColumnResult(name="eurovalue", type=BigDecimal.class),
                           @ColumnResult(name="eurotch", type=BigDecimal.class),
                         }
                       )
                     })
    @Entity 
    public class Elaboration{
      @Id
      private Long id;
      private String areadesc;
      private String subsectordesc;
      private Integer dossiercount;
      private BigDecimal eurovalue;
      private BigDecimal eurotch; 

    ....

和自定义查询:

        String statisticValueQuery = "select  a.mdescr as areadesc, s.mdescr as subsectordesc, sum(euro_value) as eurovalue, 
    sum(euro_value_tch) as eurotch " +
                                   "from dossier d " +
                                   "join dossier_document dd on d.id = dd.dossier_id " +
                                   "join dossier_country dc on d.id = dc.dossier_id " +
                                   "join country c on dc.country_id = c.id " +
                                   "join area a on c.area_id = a.id " +
                                   "join dossier_subsector ds on d.id = ds.dossier_id " +
                                   "join subsector s on ds.subsector_id = s.id " +
                                   "where dd.document_id = :document  " +
                                   "and d.submission_date >= :startdate  and d.submission_date <= :enddate " +
                                   "group by s.id, a.id;";

      public List<Elaboration> getValueElaboration(ElaborationRequestDTO elaborationRequestDTO){

        Query resultMapping = em.createNativeQuery(statisticValueQuery, "ValueMapping");
        resultMapping.setParameter("startdate", elaborationRequestDTO.getElaborateFromEquals());
        resultMapping.setParameter("enddate", elaborationRequestDTO.getElaborateToEquals());
        resultMapping.setParameter("document", elaborationRequestDTO.getDocumentIdEquals());
        return resultMapping.getResultList();

有没有办法通过验证测试？
谢谢

这是错误的说法。

Hibernate needs to declare this class (Elaboration) as @Entity

你应该把你的 @SqlResultSetMapping以上部分声明 @Entity但它可以是与 Elaboration 无关的其他实体.

@SqlResultSetMapping(name="ValueMapping",
                 classes={
                   @ConstructorResult(
                     targetClass=Elaboration.class,
                     columns={
                       @ColumnResult(name="areadesc", type=String.class),
                       @ColumnResult(name="subsectordesc", type=String.class),
                       @ColumnResult(name="eurovalue", type=BigDecimal.class),
                       @ColumnResult(name="eurotch", type=BigDecimal.class),
                     }
                   )
                 })
@Entity 
public class SomeEntity {

}

如果 Elaboration不是一个实体，你不应该这样注释它。
