I upgraded to Springboot 3.0 and in my hibernate entity class has something like:
#Column(columnDefinition = "jsonb", nullable = false, updatable = true, name = "accounts")
#Type(type = "jsonb")
private ArrayList<Account> accounts;
But I'm getting the exception 'Cannot resolve method 'type' since upgrading to Springboot 3.0 and moving to Jakarta persistence.
I need a replacement for com.vladmihalcea.hibernate.type.json.JsonBinaryType;
I found the answer:
I had to use the lib:
<groupId>com.vladmihalcea</groupId>
<artifactId>hibernate-types-60</artifactId>
and in the entity:
#Column(columnDefinition = "jsonb", nullable = false, updatable = true, name = "accounts")
#Type(JsonBinaryType.class)
private ArrayList<Account> accounts;
In Hibernate 6, the mapping annotations are much more typesafe. You're usually required to specify Class references instead of stringly-typed names.
If you want to model JSON, I would suggest you to use #JdbcTypeCode(SqlTypes.JSON) which is how you model JSON with plain Hibernate ORM Core. Also see https://docs.jboss.org/hibernate/orm/6.1/userguide/html_single/Hibernate_User_Guide.html#basic-mapping-json

im working in spring boot project i want to map a property with serial (using my sequence) column in my table and this column is not the ID.
i found this solution :
#Column(name = "DEMANDE_NUMBER", insertable = false, updatable = false, columnDefinition = "serial")
private Integer demandeNumber;
(because #GeneratedValue persist null and doesn't use the sequence)
this solution works fine and the field is persisted in my DB and the value uses the sequence but when i get my object after saving using my repository the demandeNumber is null
Demande savedDemande= demandeRepository.save(demandeToSave);
//demandeObj .getDemandeNumber() return null
any suggestion to resolve this issue please ?
Thanks.
according to this answer How to use a sequence generator for a non ID field?
i added the following annotation on my property
#Generated(GenerationTime.INSERT)
#Column(name = "column_name", columnDefinition = "serial", updatable = false)
you should import the package from hibernate and not javax.persistence.
import org.hibernate.annotations.Generated;
import org.hibernate.annotations.GenerationTime;
i hope this can help other people in the future. note this solution is for spring data with postgresql.
I'm upgrading my project to Spring Boot 2.1.18 that uses Hibernate 5.3.18.
Previously, my entity looked like thus and would use the SequenceHiLoGenerator:
#Entity
#Table(name = "group_link")
#SequenceGenerator(name = "group_link_seq", sequenceName = "group_link_seq")
public class GroupLinkEntity extends BaseObject {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "group_link_seq")
#Column(name = "group_link_id", unique = true, nullable = false)
private Long id
}
Now, by default in Hibernate 5, it uses the SequenceStyleGenerator which causes constraint violations because my increment size is 1 and the default allocationSize is 50.
The suggested thing to do to maintain compatibility is to set this property:
spring.jpa.properties.hibernate.use-new-id-generator-mappings: false
I do so but it does not seem to take, because the SequenceStyleGenerator is still used. From my understanding, this should cause it to use the SequenceHiLoGenerator. Is this incorrect?
However, if I modify the entity to look like the below it works as expected, replicating the previous functionality I had.
#Entity
#Table(name = "group_link")
#GenericGenerator(
name = "group_link_seq",
strategy = "org.hibernate.id.SequenceHiLoGenerator",
parameters = {
#Parameter(name = "sequence_name", value = "group_link_seq"),
}
)
public class GroupLinkEntity extends BaseObject {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "group_link_seq")
#Column(name = "group_link_id", unique = true, nullable = false)
private Long id;
}
So, it would seem the property is not being taken somehow and I'm looking to figure out why that is. I see it show up in my JpaProperties bean. If I change other properties, like my dialect, I can see that they are taking effect.
Could anyone point me to the code that actually reads that property and makes a decision on what generator to use or point out some obvious error I'm making here?
As it's stated in the documentation:
You need to ensure that names defined under spring.jpa.properties.* exactly match those expected by your JPA provider. Spring Boot will not attempt any kind of relaxed binding for these entries.
For example, if you want to configure Hibernate’s batch size you must use spring.jpa.properties.hibernate.jdbc.batch_size. If you use other forms, such as batchSize or batch-size, Hibernate will not apply the setting.
So, for your case you should use:
spring.jpa.properties.hibernate.id.new_generator_mappings: false
See also this part of hibernate documentation.
I'm writing a very simple Spring Data JDBC repository in Kotlin (using Postgres as the database):
data class Label(
#Id
#GeneratedValue
#Column( columnDefinition = "uuid", updatable = false )
val id: UUID,
val name: String
)
#Repository
interface LabelRepository: CrudRepository<Label, UUID> {}
When I do repository save:
val l = Label(id = UUID.randomUUID(), name = "name")
labelRepo.save(l)
It works fine. But since id is not null Spring Data JDBC will always treat it as an "update" to an existing label entity instead of creating a new one with generated ID.
So I changed id: UUID to id: UUID? And having val l = Label(id = null, name = "name")
But call the same save() method gives me:
java.lang.NoSuchMethodError: 'org.springframework.data.relational.core.dialect.IdGeneration org.springframework.data.relational.core.dialect.Dialect.getIdGeneration()'
I have tried a solution here: https://jivimberg.io/blog/2018/11/05/using-uuid-on-spring-data-jpa-entities/
But it didn't work, still gives me the same error
Wondering what's the cause of this and why this error pops up only when I change UUID to UUID??
nvm, turns out I have to use the implementation("org.springframework.boot:spring-boot-starter-data-jdbc") dependency instead of implementation("org.springframework.data:spring-boot-starter-data-jdbc:2.1.3")
I am using Spring JPA
#Column(name = "rec_cren_tm", insertable = false, updatable = false)
private Timestamp recCrenTm;
which is using database timestamp and inserting properly.
But while fetching I am getting this is property as null. Below is what I am using on the method
#Transactional
public interface IClaimRepository extends JpaRepository<Claim, Long> {
#Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
List<Claim> findByLnId(String LnId);
How do I get this?
This is the same answer i am looking for How to map timestamp column to JPA type?
But this thread doesnt have solution i am looking for
I'm using hibernate in my spring boot application
my domain model is like this
#Entity
#Table(name = "skill")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
#Document(indexName = "skill")
#Audited
public class Skill implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
#SequenceGenerator(name = "sequenceGenerator")
private Long id;
}
The increment size of sequence is 50 and is working properly
but when I add Envers Audited annotation I see this error
conflicting values for 'increment size'. Found [50] and [1]
How can I resolve this conflict?
This doesn't sound like an Envers problem but a general mapping problem.
When you add an #Audited annotation, that simply informs Envers that it should inspect that particular entity mapping during Hibernate bootstrap and create the necessary audit objects to store the entity state during each transaction.
The generated Envers objects use their own sequence generators and primary key. The user defined generation strategy, sequences, etc are all ignored in the Envers object because the associated column is meant to just be a copy/pass-thru value, nothing special.
In other words, the Envers table would have a PK defined that mirrors this POJO:
#Embeddable
public class EnversSkillId implements Serializable {
#Column(name = "REV", nullable = false, updatable = false)
private Integer rev;
#Column(name = "id", nullable = false, updatable = false)
private Long id;
}
When Envers generates the audit record, it automatically uses its internal sequence generator to get the next value and assign it to EnversSkillId#rev and copies your entity's id value directly into the EnversSkillId#id property.
So as mentioned in the comments, your problem is very unlikely related to Envers.
