Detached Entity by changing InMemory to Spring Data JPA / Mysql

I'm trying to change the database from InMemory to MySQL with Spring Data JPA.
But I get a failure. And the ideas are missing, after I tried different things, like Annotation for Cascading and so on.
But here is my problem application:
My Repository:
package org.apache.struts.crud.dao;
import org.apache.struts.crud.model.Country;
import org.apache.struts.crud.model.Person;
import org.apache.struts.crud.service.PersonService;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
#Repository
public class PersonRepository implements PersonService {
#PersistenceContext
EntityManager manager;
#Override
public Person getPerson(Integer id) {
return manager.find(Person.class, id );
}
#Override
public Person[] getAllPersons() {
return new Person[0];
}
#Override
public void updatePerson(Person personBean) {
}
#Override
#Transactional
public void insertPerson(Person personBean) {
manager.persist(personBean);
}
#Override
public void deletePerson(Integer id) {
}
#Override
public Country[] getCountries() {
return new Country[0];
}
#Override
public String[] getCarModels() {
return new String[0];
}
#Override
public String[] getSports() {
return new String[0];
}
#Override
public String[] getGenders() {
return new String[0];
}
}
Person Object:
package org.apache.struts.crud.model;
import javax.persistence.*;
import java.util.Arrays;
/**
* Models a Person who registers.
*
* Person is Cloneable just an implemention technique for in-memory daos.

* #author bruce phillips

*/
#Entity
#Table(name = "person")
public class Person implements Cloneable {
#Id
#GeneratedValue(strategy= GenerationType.AUTO)
private Integer personId;
private String firstName;
private String lastName;
private String sport;
private String gender;
// private Country country = new Country("", "");
private boolean over21;
private String[] carModels;
private String email;
private String phoneNumber;
public Person() {
}
public Person(Integer id, String firstName, String lastName, String sport,
String gender, /*Country country,*/ boolean over21, String[] carModels,
String email, String phoneNumber) {
this.personId = id;
this.firstName = firstName;
this.lastName = lastName;
this.sport = sport;
this.gender = gender;
//this.country = country;
this.over21 = over21;
this.carModels = carModels;
this.email = email;
this.phoneNumber = phoneNumber;
}
public Integer getPersonId() {
return personId;
}
public void setPersonId(Integer personId) {
this.personId = personId;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {

}

}
public void setSport(String sport) {
this.sport = sport;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getGender() {
return gender;
}
// public void setCountry(Country country) {
// this.country = country;
// }
//
// public Country getCountry() {
// return country;
// }
public void setOver21(boolean over21) {
this.over21 = over21;
}
public boolean isOver21() {
return over21;
}
public void setCarModels(String[] carModels) {
this.carModels = carModels;
}
public String[] getCarModels() {
return carModels;
}
public void setEmail(String email) {
this.email = email;
}
public String getEmail() {
return email;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getPhoneNumber() {
return phoneNumber;
}
#Override
public Object clone() throws CloneNotSupportedException {
return super.clone();
}
#Override
public String toString() {
return "Id: " + getPersonId() + " | "
+ "First Name: " + getFirstName() + " | "
+ " Last Name: " + getLastName() + " | "
+ " Favorite Sport: " + getSport() + " | "
+ " Gender: " + getGender() + " | "
//+ " Country: " + getCountry() + " | "

+ " Car models: " + Arrays.asList(getCarModels()) + " | "

+ " Phone: " + getPhoneNumber();
}
}
Here Controller for hitting /setup:
package org.apache.struts.crud;
import org.apache.struts.crud.dao.MemoryPersonSupportDao;
import org.apache.struts.crud.dao.PersonRepository;
import org.apache.struts.crud.model.Person;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
#Controller
public class HomeController {
private PersonRepository manager;
public HomeController(PersonRepository manager){
this.manager = manager;
}
#GetMapping("/setup")
void setup (){
manager.insertPerson(new Person(1, "Bruce", "Phillips", "basketball", "male"/*,
MemoryPersonSupportDao.getCountry("US")*/, true, new String[]{"Ford", "Nissan"},
"bphillips#ku.edu", "123-456-9999"));
manager.insertPerson(new Person(2, "Antonio", "Sanchez", "mtb", "male"/*,
MemoryPersonSupportDao.getCountry("ES")*/, true, new String[]{"Toyota", "Seat"},
"asanchez#correo-e.es", "555-999-8888"));
}
}
Now i get this error:

#Website i got this error:
detached entity passed to persist: org.apache.struts.crud.model.Person; nested exception is org.hibernate.PersistentObjectException: detached entity passed to persist: org.apache.struts.crud.model.Person
Has someone a helping hand?

The problem was the #GeneratedValue(strategy= GenerationType.AUTO), because I'm setting an Id manuell and also generate one.
But the crud interface also helped until the next question. ;)

Spring boot : Serializable Exception

I am developing a forgot password service but getting a serializable Exception in getting data from the database. I am not able to find the solution for this. Please help me out.

I don't know why i got this error everything seems right. I someone wants my RegistrationModel i will edit the question and will add it.

This is serialization error, you can try using explicit serialVersionUID on the User class.
If you want more details you can take a look at javadocs on java.io.Serializable interface and this has been answered here as well
java.io.InvalidClassException: local class incompatible:

how to handle ERROR: Duplicate entry in spring jpa

I was trying to execute below code :
public void createScarceVouchers(long numberOfVouchers,int productId,String fileType,int userId) {
EntityManager entityManager=this.emf.createEntityManager();
try {
entityManager.setFlushMode(FlushModeType.COMMIT);
Product product = productService.getProductById(productId);
UserMaster userMaster = userMasterService.getOrignalUserMasterById(userId);
entityManager.getTransaction().begin();
int batchSize = 30;
for(int i=0;i<100;i++) {
Voucher voucher = null;
String strVoucher = AcfUtils.getRandom();
if(i>=2 && i<=5) {
strVoucher = "abcdefg";
System.out.println(i+"> abcdefgh");
voucher = new Voucher(product, userMaster, strVoucher, 'G',new Date());
}
else {
System.out.println(i+"> "+strVoucher);
voucher = new Voucher(product, userMaster, strVoucher, 'G',new Date());
}
entityManager.persist(voucher);
if (i % batchSize == 0 && i > 0) {
entityManager.flush();
entityManager.clear();
}
}
entityManager.getTransaction().commit();
}
catch(Exception ex) {
ex.getMessage();
}
finally {
entityManager.close();
}
}
And I was getting below exception.

I intentionally wanted this exception. Means, I was storing some keys to my Map collection. And if there exists the same key in DB then I wanted to remove that particular key from map.
So here I wanted to collect abcdefg from exception so that I can remove it from Map. Also this exception/error is marked in red color. How can I handle it to collect that value in my catch block.

From what it looks like your voucherStr is a key field and in your code it is not unique between 2-5(inclusive), which could be the cause of this exception.
