java.time.Instant 字段在更新到 SpringBoot 3 / Hibernate 6 后无法通过使用“current_timestamp”的 JPQL 查询来填充

Question

我有一个像这样的持久化实体的基类：

@EntityListeners(AuditListener.class)
@MappedSuperclass
public abstract class BaseEntity {
    @Id
    private String id;
    private Instant createdAt;
    private String createdBy;
    private Instant modifiedAt;
    private String modifiedBy;
    ...

在持久化/更新时填充创建/修改字段的侦听器：

public class AuditListener {
    @PrePersist
    private void onCreate(BaseEntity entity) {
        entity.setCreatedAt(Instant.now());
        entity.setCreatedBy(getIdUserLogged());
    }
    @PreUpdate
    private void onUpdate(BaseEntity entity) {
        entity.setModifiedAt(Instant.now());
        entity.setModifiedBy(getIdUserLogged());
    }
}

对于通过查询进行的更新，侦听器现在可以工作并且我已经手动设置了值：

@Repository
public interface IngredientRepository extends CrudRepository<Ingredient, String>  {
    @Modifying
    @Query("update Ingredient set active = false, modifiedAt = current_timestamp where id in :removedIds")
    int deactivate(@Param("removedIds") Collection<String> toBeRemoved);
}

这在 SpringBoot 2.7.x 上运行良好，但在更新到 SpringBoot 3.0.2 后，应用程序在启动时失败：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'ingredientRepository' defined in ...: Could not create query for public abstract int de.digitale_therapiebegleitung.manager_app.services.local.IngredientRepository.deactivate(java.util.Collection,java.lang.String); Reason: Validation failed for query for method public abstract int de.digitale_therapiebegleitung.manager_app.services.local.IngredientRepository.deactivate(java.util.Collection,java.lang.String)

我找不到 Hibernate 6 中的任何更改来解释更改的内容。 一种解决方案是将

modifiedAt

字段更改为 java.sql.Timestamp ...但不是很好。

当 Hibernate 在版本 5 中引入这些类型的专有映射时，它将 Instant 映射到 SqlType.TIMESTAMP 并将 Duration 映射到 Types.BIGINT。 Hibernate 6 改变了这个映射。它现在将 Instant 映射到 SqlType.TIMESTAMP_UTC，将 Duration 映射到 SqlType.INTERVAL_SECOND。

这些新映射似乎比旧映射更适合。因此，他们在 Hibernate 6 中对其进行了更改是件好事。但它仍然破坏了现有应用程序的表映射。如果遇到该问题，可以将配置属性 hibernate.type.preferred_instant_jdbc_type 设置为 TIMESTAMP 并将 hibernate.type.preferred_duration_jdbc_type 设置为 BIGINT。
