I have an existing JPA entity ("Reference") with an ID column as its primary key that it inherits from a base class "BaseEntity" (using the #MappedSuperclass annotation on the superclass).
I also have a 1-M relationship between a Reference and another entity called Violation. Violation was previously defined with a foreign key "REFERENCE_ID" to the "ID" column of the Reference entity.
Recently, I tried to add an unrelated composite key to the Reference entity. This should not have affected the 1-M relationship between Reference and Violation. However, when I run the code in my tomcat server, I see the following stack trace:
Caused by: org.hibernate.AnnotationException: referencedColumnNames(ID) of org.qcri.copydetection.sdk.metastore.entity.Violation.reference referencing org.qcri.copydetection.sdk.metastore.entity.Reference not mapped to a single property

To cut a long story short, I'm totally confused how to go about adding a composite key to an existing (legacy) entity that already has an ID column. I can't remove the ID column, nor can I change the 1-M relationship between Reference and Violation. I can't for the life of me understand the error message because the "REFERENCE_ID" foreign key column of the Violation entity is being mapped to a single "ID" column of the Reference entity.
Many thanks in advance!

Project is based on JPA persistance with two Entities (Deaprtment and Employee)
Department(OneToMany) and Employee(ManyToOne)
Whenever I send a request via API there's a StackOverFlow error. So far I back Traced the main cause which is the stack is full is indefinite recursion. Could someone explain why this happened ususally it shouldn't have confused by bidirectioanl relationship of entities.
package com.springjpacrud01.model;
import javax.persistence.*;
import java.util.List;
#Entity
#Table(name = "department")
public class Department {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#Column(name = "name")
private String name;
#OneToMany(mappedBy = "department", fetch = FetchType.LAZY)
List<Employee> employees;
public Department() { }
public Department(Long id, String name) {
this.id = id;
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Employee> getEmployees() {
return employees;
}
public void setEmployees(List<Employee> employees) {
this.employees = employees;
}
}
import com.fasterxml.jackson.annotation.JsonBackReference;
import javax.persistence.*;
#Entity
#Table(name = "employees")
public class Employee {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "name")
private String name;
#Column(name = "position")
private String position;
#ManyToOne
#JoinColumn(name = "department_id")
private Department department;
public Employee(Long id, String name, String position) {
this.id = id;
this.name = name;
this.position = position;
}
public Employee() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPosition() {
return position;
}
public void setPosition(String position) {
this.position = position;
}
public Department getDepartment() {
return department;
}
public void setDepartment(Department department) {
this.department = department;
}
}
After I just deleted the getters/setters from the Department entity it worked but
it shouldn't have work like that and I want why I cannot do relation pointing to each other entities? It couldn't form JSON response because of the infinite recursion of pointing to each other I guess. How can I solve it effectively in order to retrieve Employees by department ID, thank you)
If someone needs it I've solved this by understanding the deep root of the cause which was #JoinColumn created and addressed by Hibernate to that empty common column which I deleted manually. And when I was requesting the department_id of the employee via the employee repository Hibernate sort of got stuck in an infinite loop of going to the employee repository and from there to the department repository and in the department repository going to the employee repository. To stop that I've mapped the relation differently by making a configuration of the department
#OneToMany(mappedBy = "department", cascade= CascadeType.ALL, orphanRemoval=true) private Set<Employee> employeeHashSet = new HashSet<>();
And
#ManyToOne
#JoinColumn(name = "department_id")
private Department department;
when there is a many to one associate between two object in hibernate(JPA) and we want insert a ID of parent to child table without new record in parent table how do I implement it?
#ManyToOne(targetEntity = RoleEntity.class,cascade = CascadeType.ALL,fetch = FetchType.LAZY)
#JoinColumn(name = "FK_ROLE_ID",referencedColumnName = "ID")
private RoleEntity role;
I write this:
UserEntity userEntity=new UserEntity();
userEntity.setUserName(username);
userEntity.setPassword(password);
userEntity.setCreatedDate(new Date().toString());
RoleEntity roleEntity=new RoleEntity();
roleEntity.setTitle("user");
userEntity.setRole(roleEntity);
but the last three line also insert a new record in user table.
This completely of roleEntity:
package Entity;

I have found the solution
I set cascade = CascadeType.REMOVE in child object and it works
I have to implementes Auditing in my aplication.. i inserting this data correctly
but i want to save all atributter from my Entity ,
Exemple, name, epigrafe, .. and olthers.
I implemented the mothod but dosent work, just dont save the atributte..
lets see..
#Entity
#EntityListeners(AuditingEntityListener.class)
#Table(name = "logradouros_historico", schema = "aud")
public class LogradourosHistorico {
#Id
#GeneratedValue
private Long id;

private Acoes acao;
#Column(name = "nome")
private String nome; //nome do logradouro
public LogradourosHistorico() {
super();
}
public LogradourosHistorico(Logradouros logradouro, String modificadoPor,
Acoes acao) {
super();
this.logradouro = logradouro;
this.modificadoPor = modificadoPor;
this.acao = acao;
}
//getters and setters
my class entityListner
public class LogradourosEntityListener {
#PostPersist
public void prePersist(Logradouros target) {
perform(target, Acoes.INSERTED);
}
#PreUpdate

private void perform(Logradouros target, Acoes acao) {
target.getNome();
EntityManager entityManager = BeanUtil.getBean(EntityManager.class);
entityManager.persist(new LogradourosHistorico(target, acao));
}
}
my class Logradouros
#Entity
#EntityListeners(LogradourosEntityListener.class)
#Table(name = "logradouros", schema = "glb", uniqueConstraints= #UniqueConstraint(columnNames={"id_entidade", "idLogradouro"}))
public class Logradouros extends Auditable<String> implements Serializable {
private static final long serialVersionUID = 3703309412387185484L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int idLogradouro;
#Column(name = "cep_geral")
private String cepGeral;
#Column(name = "epigrafe")
private String epigrafe;
#NotNull
#Column(name = "nome")
private String nome;
#Column(name = "nome_exibicao")
private String nomeExibicao;
#JoinColumn(name = "id_entidade")
#ManyToOne(/*cascade = CascadeType.ALL*/)
private Entidades entidade;
#NotNull
#JoinColumn(name = "id_municipio")
#ManyToOne(/*cascade = CascadeType.ALL*/)
private Municipios municipio;
// gettrs and settrs
so what i did wrong because i cant get the nome of entity Logradouros

I am not sure what I am doing wrong. Could use some insight and help on what I am missing here.
My Entity classes are as follows:

#Id

public Date getSwrhxmlTimeStamp() {
return SwrhxmlTimeStamp;
}
public void setSwrhxmlTimeStamp(Date SwrhxmlTimeStamp) {
this.SwrhxmlTimeStamp = SwrhxmlTimeStamp;
}
}
You use
`mappedBy = "swbhxml"`
^
|___ b here
, but the annotated association is
Swbhxml getSwrhxml()
^
|___ r here
Your getter and setter are named incorrectly. And frankly, with such cryptic and close entity names, you'll probably have many such bugs.
I got a problem with JPA and ManyToMany association.
I got two class FOA_PARAM_EMPLOYE and FOA_PARAM_POSITION, and an association table FOA_PARAM_EMPLOYE_POSITION.

})
private List<FoaParamPosition> foaParamPositions;
public FoaParamEmployePK getId() {
return this.id;
}
public void setId(FoaParamEmployePK id) {
this.id = id;
}
public String getActeurMajOccur() {

}
public void setActeurMajOccur(String acteurMajOccur) {
this.acteurMajOccur = acteurMajOccur;
}
public String getAdresseEmail() {
return this.adresseEmail;
}
public void setAdresseEmail(String adresseEmail) {
this.adresseEmail = adresseEmail;
}
public List<FoaParamPosition> getFoaParamPositions() {
return foaParamPositions;
}
public void setFoaParamPositions(List<FoaParamPosition> pFoaParamPositions) {
this.foaParamPositions = pFoaParamPositions;
}
}
Class FoaParamPosition :

#Column(name="ACTEUR_MAJ_OCCUR")
private String acteurMajOccur;
#Column(name="CD_PROFIL_AFFECTATION")
private String cdProfilAffectation;

}
public void setFoaParamEmployes(List<FoaParamEmploye> pFoaParamEmployes) {
this.foaParamEmployes = pFoaParamEmployes;
}
}
Table FOA_PARAM_EMPLOYE_POSITION has this columns :
COD_ENTREP
ID_EMPLOYE
ID_POSITION
XQCIF
ACTEUR_MAJ_OCCUR
DATE_HEURE_MAJ_OCCUR
I got this exception :
A Foreign key refering com.groupama.middlgan.entities.FoaParamPosition from
com.groupama.middlgan.entities.FoaParamEmploye has the wrong number of column.
should be 2
If I add COD_ENTREP on inverseJoinColumns in my FoaParamEmploye entity, I got this exception :
Repeated column in mapping for collection:
com.groupama.middlgan.entities.FoaParamEmploye.foaParamPositions column: COD_ENTREP
Any idee ?
[I am assuming you are listing the columns for the association table FOA_PARAM_EMPLOYE_POSITION, not FOA_PARAM_EMPLOYE, as you state in your question.]
Your mappings imply FOA_PARAM_EMPLOYE_POSITION.COD_ENTREP is part of two foreign keys, one referencing FOA_PARAM_EMPLOYE and one referencing FOA_PARAM_POSITION. In practice these two foreign keys might contain the same value for COD_ENTREP, but this cannot be enforced by the database or JPA.
You should probably model the relationship differently, possibly add another, container-like, object that has bi-directional one-to-many relationships with both FoaParamEmploye and FoaParamPosition and shares parts of its primary key with the other two primary keys.
If you want to keep your inverseJoinColumn mapping you can do as follows,
#ManyToMany
#JoinTable(
name = "FOA_PARAM_EMPLOYE_POSITION",
joinColumns = { #JoinColumn(name = "ID_EMPLOYE"),
#JoinColumn(name = "COD_ENTREP") }
,
inverseJoinColumns = {#JoinColumn(name = "FOAPARAMPOSITION_COD_ENTREP"), #JoinColumn(name = "FOAPARAMPOSITION_ID_POSITION")}
)
private List<FoaParamPosition> foaParamPosition;
and
#ManyToMany
#JoinTable(
name = "FOA_PARAM_EMPLOYE_POSITION",
joinColumns = { #JoinColumn(name = "ID_POSITION"),
#JoinColumn(name = "COD_ENTREP") }
,
inverseJoinColumns = {#JoinColumn(name = "FOAPARAMEMPLOYE_COD_ENTREP"), #JoinColumn(name = "FOAPARAMEMPLOYE_ID_EMPLOYE")}
)
private List<FoaParamEmploye> foaParamEmploye;
the mappings are aligned with the code you've posted in your other question JPA Many To Many Select
