java.time.Instant field cannot be filled by JPQL query using "current_timestamp" after update to SpringBoot 3 / Hibernate 6

Question

I have a base class for persisted entities like this:

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

A listener to fill the created/modified fields on persiste/update:

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());
    }
}

For updates made by query the listener would now work and I've manually set the value:

@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);
}

This worked fine with SpringBoot 2.7.x but after update to SpringBoot 3.0.2, app fails on start:

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)

我在 Hibernate 6 中找不到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...但这并不好。

Answer 1

我在从 Spring Boot 2 升级到 3 时遇到了类似的问题。我尝试按照建议的配置进行更改，hibernate.type.preferred_instant_jdbc_type但TIMESTAMP没有成功。

在我非常相似的情况下唯一有效的方法是替换current_timestamp我的查询中的文字instant。

所以，就你而言：

update Ingredient set active = false, modifiedAt = instant where id in :removedIds
