Spring JPA :: Aucun convertisseur trouvé capable de convertir à partir du type

J'utilise spring avec JPA et j'essaie d'exécuter la requête en utilisant @query avec SQL query.and j'essaie de mapper le résultat sur un objet. J'ai une classe d'entité et un mappage différents vers d'autres dto car je ne veux pas toutes les colonnes. descendre en dessous de l'erreur

Aucun convertisseur trouvé capable de convertir du type [org.springframework.data.jpa.repository.query.AbstractJpaQuery $ TupleConverter $ TupleBackedMap] en type [webapi.dto.StatsDTO] ",

Ci-dessous mon interface de dépôt

public interface UserRepository extends CrudRepository<UserEntity, Long> {
    @Query(value = "select count(type_id) userCount, type_id, modified_at from "
                + "user_campaign_objective where camp_id = ?1 group by objective_type_id,modified_at", nativeQuery = true)

        List<StatsDTO> getStatsDTO(Long camp_id);
}

Ci-dessous se trouve StatsDTO.

@Data
@NoArgsConstructor
@AllArgsConstructor
public class StatsDTO {
    private Integer userCount;
    private Byte typeId;
    private Instant modifiedAt;

}
  1. comment résoudre le problème ci-dessus.
  2. si le problème n'est pas réparable, pouvons-nous le faire sans @query en utilisant les données de printemps jpa? Comment?

Edit :: Utilisation de JPQL ::

@Query("select new webapi.campaign.dto.StatsDTO(count(u.objective_type_id),u.objective_type_id,u.modified_at) "
        + "from user_campaign_objective u where u.campaign_id = ?1 group by u.objective_type_id,u.modified_at")

descendre en dessous de l'erreur

Si vous utilisez une requête native à l'aide de SQL, obtenez une erreur inférieure à

@Query(value = "select count(objective_type_id), objective_type_id, modified_at from "
        + "user_campaign_objective where campaign_id = ?1 group by objective_type_id,modified_at", nativeQuery = true)

Vous pouvez utiliser l'expression constructeur JPQL query, votre requête ressemble à ceci:

select new StatsDTO(count(u),u.typeId,u.modifiedAt) from UserCampaignObjective u where campId = ? group by objectiveTypeId,modifiedAt

Mais vous vous assurez que le constructeur StatsDTO existait déjà.

Vous pouvez résoudre ce problème et obtenir le résultat en utilisant projections en faisant de votre DTO une interface avec des getters pour les colonnes retournées par la requête. C'est ce que j'ai fait lorsque j'ai été confronté au même problème.

Par exemple, dans votre cas, changez StatsDTO en interface comme indiqué ci-dessous, assurez-vous de donner un alias pour vos colonnes si vous utilisez '.' opérateur:

public interface StatsDTO {
    Integer getUserCount;
    Byte getTypeId;
    Instant getModifiedAt;
}

Également dans votre requête, donnez un alias pour vos colonnes comme userCount, typeId, modifiedAt respectivement afin qu'il soit correctement mappé.

Vous avez un décalage entre les noms de colonne:

  • userCount
  • type_id
  • modified_at

Et les noms de vos propriétés:

  • userCount
  • typeId
  • modifiedAt

Comme il s'agit d'une requête native, la stratégie de dénomination JPA ne s'applique pas et les noms de colonne doivent correspondre aux noms de propriété. Donc, si vous modifiez la requête comme suit, cela devrait fonctionner:

select count(type_id) userCount, type_id as typeId, modified_at as modifiedAt from ...

Vous pouvez également essayer de modifier la déclaration de l'interface UserRepository en dessous,

public interface UserRepository extends CrudRepository<StatsDTO, Long> {
    @Query(value = "select count(type_id) userCount, type_id, modified_at from "
                + "user_campaign_objective where camp_id = ?1 group by objective_type_id,modified_at", nativeQuery = true)

        List<StatsDTO> getStatsDTO(Long camp_id);
}

Le changement est: CrudRepository <StatsDTO, Long> de CrudRepository < UserEntity, Long>.

J'ai rencontré le même problème lors de l'utilisation d'un autre objet de données dans un référentiel déclaré avec un autre objet de données.
