One to many Hibernate Entity classes + spring boot + mariaDB Exception - jpa

Question

I create a table with the following cardinality Person->(many) Adress
I created the table in mariaDB with the following sql:
create table person
(name VARCHAR(100) NOT NULL,
personnummer VARCHAR(12) NOT NULL,
id INT(11) NOT NULL AUTO_INCREMENT,
CONSTRAINT person_pk PRIMARY KEY (id)
);
create table adress
(
id INT(11) NOT NULL AUTO_INCREMENT,
gata VARCHAR(100) NOT NULL,
postnummer int(12) NOT NULL,
person_id int(11) NOT NULL,
CONSTRAINT adress_pk PRIMARY KEY (id),
CONSTRAINT person_id_foreign FOREIGN KEY (person_id) REFERENCES person(id)
);
The Entity classes looks like this:
PERSON
import javax.persistence.*;
import javax.validation.constraints.NotNull;
import java.io.Serializable;
import java.util.*;
import java.util.List;
#Entity
#Table(name = "person")
public class Person implements Serializable {
private String personnummer;
private String name;
#OneToMany(mappedBy = "person", cascade = CascadeType.ALL)
private List<Adress> adresses = new ArrayList<>();
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Basic(optional = false)
private long id;
public void setPersonnummer(String personnummer) {
this.personnummer = personnummer;
}
public void setName(String name) {
this.name = name;
}
public String getPersonnummer() {
return personnummer;
}
public String getName() {
return name;
}
public void setId(long id) {
this.id = id;
}
#Id
public long getId() {
return id;
}
public void setAdresses(List<Adress> adresses) {
this.adresses = adresses;
}
#OneToMany(mappedBy = "person", cascade = CascadeType.ALL)
public List<Adress> getAdresses() {
return adresses;
}
#Override
public int hashCode() {
int hash = 7;
hash = 79 * hash + Objects.hashCode(this.id);
hash = 79 * hash + Objects.hashCode(this.name);
hash = 79 * hash + this.personnummer.hashCode();
return hash;
}
}
ADRESS:
import javax.persistence.*;
import java.io.Serializable;
import java.util.Objects;
#Entity
#Table(name = "adress")
public class Adress implements Serializable {
private String gata;
private int postnummer;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
// private Long personId;
// #JoinColumn(name = "person_id", referencedColumnName = "id", nullable = false)
#ManyToOne
#JoinColumn(name = "person_id")
private Person person;
#ManyToOne(targetEntity = Person.class)
#JoinColumn(name = "person_id")
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
public void setId(long id) {
this.id = id;
}
#Id
public long getId() {
return id;
}
public String getGata() {
return gata;
}
public int getPostnummer() {
return postnummer;
}
public void setGata(String gata) {
this.gata = gata;
}
public void setPostnummer(int postnummer) {
this.postnummer = postnummer;
}
#Override
public int hashCode() {
int hash = 7;
hash = 79 * hash + Objects.hashCode(this.id);
hash = 79 * hash + Objects.hashCode(this.gata);
hash = 79 * hash + Objects.hashCode(this.postnummer);;
return hash;
}
}
The main "class" really just a spring boot component looks like:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
import se.skv.uhzk.db.entity.Adress;
import se.skv.uhzk.db.entity.Person;
import java.util.ArrayList;
import java.util.List;
#Component
public class TestRunner implements CommandLineRunner {
private static final Logger logger = LoggerFactory .getLogger(TestRunner.class);
#Autowired
private PersonJpaRepository personRepository;
#Autowired
private AdrressJpaRepository adressRepository;
#Override
public void run(String... args) throws Exception
{
try {
System.out.println("----------------TestRunner---------------- ");
logger.info("TestRunner Starting ");
Person person = new Person();
person.setName("Alvaro Rubio");
person.setPersonnummer("7107050852");
Adress adress = new Adress();
adress.setGata("el gata");
List<Adress> l = new ArrayList<>();
l.add(adress);
person.setAdresses(l);
adress.setPerson(person);
System.out.println("SAVING PERSON ID: " + person.getId());
personRepository.save(person);
logger.info("TestRunner # of cities: {}", personRepository.count());
List<Person> personList = personRepository.findAll();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
När vi kör koden så får vi följande fel:

We have tried many solutions but the code doesn't work. I we removed
person.setAdresses(l);
It is ok then the information is stored in the Person table, could somebody help me/us!!!!!!

Answer 1

You are using #OneToMany annotation 2 times in your Person class.
You don't have to use #OneToMany annotation before your getAdresses() method.
