In a Spring Boot application, for a particular use case (data export & import), we would like to preserve the identifiers for objects that are otherwise assigned automatically by @GeneratedValue(strategy = GenerationType.IDENTITY). To achieve that, we were able to just set the ID manually, and Hiber…

You cannot manually set generated identifier values using the default identifiers. Thanks to a recent improvement Jira , you can however define a custom generator implementation that overrides the allowAssignedIdentifiers(), returning true, to allow for a custom implementation to sporadically use pre…

I have the same problem, but I am using the custom @ IdGeneratiorType method. I found that in version 6.6, the following judgment has been added. It may be the problem caused by this. //org.hibernate.event.internal.DefaultMergeEventListener protected void entityIsDetached(MergeEvent event, Object…

[image] robert82h: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) Thank you very much, it has been resolved.

Yes, that’s it, thank you very much.

I did as you said, but it’s not work. My code is shown below, please help me public class SnowFlakeIdGenerator implements IdentifierGenerator { @Override public Object generate(SharedSessionContractImplementor session, Object owner) { if (Objects.nonNull(owner)) { fina…

@Setter @Getter @EntityListeners(AuditingEntityListener.class) @MappedSuperclass public abstract class JpaBaseEntity { @Column(length = 32, updatable = false) @CreatedBy private String createBy; @Column(updatable = false) @CreatedDate private LocalDateTime createTime; …

@mbladel As @Jimmy said it is not working. I did a custom id generation and it breaks the majority of integration testes for example an update by id test assumes an entity exists with a predetermined ID before executing the update. Now it breaks at insertion of the entity with id.

Here is my code, you can compare the differences. AbstractIdGeneratiorType is a general code abstraction that serves as a reference for UUIDGenerator code. public abstract class AbstractIdGeneratorType implements IdentifierGenerator { private final UuidValueGenerator generator; private fin…

Similarly, I also have a simplified version of Snowflake Id generator for your reference. public class SnowflakeIdGeneratorType implements IdentifierGenerator { private final Snowflake snowflake; private final Class<?> propertyType; public SnowflakeIdGeneratorType(SnowflakeIdGenerator …

I have created a demo project on GitHub, you can try it . If you switch to Spring Boot 3.3.7 version, it will be successful, but if you switch to Spring Boot 3.4.1 version, there will be problems org.springframework.orm.ObjectOptimisticLockingFailureException: Row was updated or deleted by another t…
