Hibernate doesn't creating table based on entity

After starting the program (launching TomCat) there are no tables created in the schema, but the table "player" has to be created automatically.
I checked hibernate config, but can't find where is the problem.
I've tried changing hbm2ddl.auto to hibernate.hbm2ddl.auto (also create, create-drop etc.) but it didn't help.
If there are any ideas, please let me know. Thanks.

1-Hibernate does not recognize your repository. You should not mark repo classes as #Repository because they are not interfaces and in your example they are working like a service. So they can be #Service.
2-Do not implement IPlayerRepository. Mark it as #Repository and just autowire it to your service classes (or use constructor injection and just use like a variable)
Like:
#Service
public class PlayerRepositoryDB {
private IPlayerRepository playerRepository;
public PlayerRepositoryDB (IPlayerRepository playerRepository){ //CONSTRUCTOR
this.playerRepository = playerRepository;...
3- DB repository classes are implementing IPlayerRepository but it must be marked as #Repository and It should extend either CrudRepository or JpaRepository (which extends CrudRepository already).
Like:
#Repository
public interface IPlayerRepository extends JpaRepository<Player, Long> {
//Here are the methods;
}
Here, the Long is the type of primary key of Player class.

Hibernate XML:
<property name="hibernate.connection.CharSet">utf8mb4</property>
<property name="hibernate.connection.characterEncoding">UTF-8</property>
<property name="hibernate.connection.useUnicode">true</property>
Connection url:
db.url=jdbc:mysql://localhost:3306/db_name?useUnicode=true&character_set_server=utf8mb4
As a side note I would like to make one clarification that UTF-8 is the character encoding while utf8mb4 is a character set that MySQL supports. MySQL's utf8mb4 is a superset to MySQL's utf8.
Spring/Hibernate filter:
<form accept-charset="UTF-8">

Problem solved.
It was because of javax.persistence.; import instead of
jakarta.persistence. in entity class.

Hibernate Util Class

I'm trying to rewrite a java app that i had, cause i made many changes to the database.
I did a copy/paste of the HibernateUtil class that i had to my new app. And it just does not seem to work :( .
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
private static SessionFactory sessionFactory = null;
static {
sessionFactory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
}
public static Session getSession() {
Session session = null;
if (threadLocal.get() == null) {
// Create Session object
session = sessionFactory.openSession();
threadLocal.set(session);
} else {
session = threadLocal.get();
}
return session;
}
public static void closeSession() {
Session session = null;
if (threadLocal.get() != null) {
session = threadLocal.get();
session.close();
threadLocal.remove();
}
}
public static void closeSessionFactory() {
sessionFactory.close();
}
}
That's the error i get:

Exception running application Mach
Also, i would really appreciate if you could help me build my own. Though FOR NOW, i just want to finish my app. I have worked many days reconstructing the database for new demands, i have almost the whole code ready, and i'm stuck on this :/ feels bad.
I already check my hibernate.cfg.xml file and seems ok!
Here is my Entity class:

private PermisEntity permisByPermisId;
#Id
#Column(name = "WorkerID", nullable = false, length = 20)
public String getWorkerId() {
return workerId;
}

}
#Basic
#Column(name = "UserLogName", nullable = true, length = 15)

}
And here is the Entity, of the table that is related with the previous one:
package Entities;

}
public void setUserIsWorkerByUserId(UserIsWorkerEntity userIsWorkerByUserId) {

}
And finally, this is my hibernate.cfg.xml file:

The error complains about Object field type for info field in ObjectEntity entity class. Changing to appropriate type will solve the problem.
Also, look at a similar problem.

I use Oracle 11g .
I tried to solve the problem by solving similar questions, but I could not .
for example I checked the following topics that were more similar to my problem :
[Error creating bean with name 'entityManagerFactory' defined in class path resource : Invocation of init method failed
[Getting Exception in thread "main" java.lang.ExceptionInInitializerError Exception
Additional explanation: No tables have been created in the database so far.

Looks like problem is with #JoinColumn(name = "FK_PERSON",referencedColumnName = "UID")
referencedColumnName attribute points to the related column in asociated/referenced entity, i.e. column name of the primary key. By default it is primary key of associated entity. You are not required to fill the referencedColumnName if the referenced entity has single column as PK, because there is no doubt what column it references (i.e. primary key column of associated entity).
change that line to #JoinColumn(name = "FK_PERSON") it should work.
For more info about referencedColumnName refer to "What is referencedColumnName used for in JPA?"

Hibernate: New Session without dropping the tables

I am new to Hibernate (implementing since yesterday) and i succesfully created a method, that transfers my Customer Objects to the Database.
After i quit my application and start it again and create a new session (in an other method) based on my hibernate.cfg.xml file with this setting:
<property name="hibernate.hbm2ddl.auto">create</property>
It leads to that point, that all relevant tables, created with Hibernate are being deleted.
So maybe that is a comprehension question, but i think "transparent persistence by hibernate" means also, that my POJO's are persistent beyond the runtime of my application!?
So i read several topics on Stackoverflow and tried it with this setting:
<property name="hibernate.hbm2ddl.auto">update</property>
But this leads to SQL errors:
com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Duplicate entry '1' for key 'PRIMARY'
Of course i don't want have duplicates, so i suppose that hibernate doesn't send a SQL Statement referring to an existing object.
It sends a Statement like this:
UPDATE `customer` SET `id`=1,`birthday`='1990-10-05 00:00:00',`forename`='TestCustomer',`gender`='F',`generatedProfitsLastYear`='0',`generatedProfitsTotal`='0',`surename`='A',`gcid`='1'
But i need the same statement, with a
Where `id`=1
at the end.
So basically what i want is, that hibernate doesn't drop all the tables and creates it again when i restart my application and create a new session based on the configuration file. So after i open a new session, i can transfer the Customer Objects stored in the database to POJOs.
Did i understand the concept of hibernate incorrectly or am i making a typical beginners mistake?
Below you will find my Customer Class:
#Entity
#Table(name="CUSTOMER")
public class Customer {
private int id;
private String forename;
private String surname;
private char gender;
private Date birthday;
private double generatedProfitsTotal;
private double generatedProfitsLastYear;
private CustomerGroup assignedTo;
public Customer(int id, String forename, String surname, char gender,
Date birthday) {
super();
this.id = id;
this.forename = forename;
this.surname = surname;
this.gender = gender;
this.birthday = birthday;
}

return id;
}
public void setId(int id) {
this.id = id;
}
#Column(name = "forename")
public String getForename() {
return forename;
}
public void setForename(String forename) {
this.forename = forename;
}
#Column(name = "surename")
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
#Column(name = "gender")
public char getGender() {
return gender;
}
public void setGender(char gender) {
this.gender = gender;
}
#Column(name = "birthday")
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
#Column(name = "generatedProfitsTotal")
public double getGeneratedProfitsTotal() {
return generatedProfitsTotal;
}
public void setGeneratedProfitsTotal(double generatedProfitsTotal) {
this.generatedProfitsTotal = generatedProfitsTotal;
}
#Column(name = "generatedProfitsLastYear")
public double getGeneratedProfitsLastYear() {
return generatedProfitsLastYear;
}
public void setGeneratedProfitsLastYear(double generatedProfitsLastYear) {
this.generatedProfitsLastYear = generatedProfitsLastYear;
}
#ManyToOne(fetch=FetchType.EAGER)
#JoinColumn(name="gcid", nullable=true, insertable=true, updatable=true)
public CustomerGroup getAssignedTo() {
return assignedTo;
}
public void setAssignedTo(CustomerGroup assignedTo) {
this.assignedTo = assignedTo;
}
}
my hibernate config file:

<mapping class="studyproject.CustomerGroup"/>
<mapping class="studyproject.BonusPackage"/>
</session-factory>
</hibernate-configuration>
Thanks

try session.saveOrUpdate() method where you have used session.save() it will prevent your database from dropping while fetching data use it with hbm2ddl.auto update. it worked for me. hope it helps.

What did you do where the 'duplicate error' occurs? Now I have the hibernate.hbm2ddl.auto configured as yours, but it's okay saving or updating entity in my local.

Why does Spring close the DB-session in Runnable after first Repository method call?

I'm working on a Spring MVC App with JPA (Hibernate as Provider) and a PostgreSQL database. I wanted to insert results (of a time consuming task) into the database in background and created a serviceclass which implements Runnable. In the run method, I receive an entity from the repository but when I try to access a lazy collection of the entity, the database session is already closed (I get a lazy initialization exception).
The source code of my Background-Service:
#Service
#Scope("prototype")
public class ProjectServiceTestThread implements Runnable{
static Logger log = Logger.getLogger(ProjectServiceTestThread.class);
#Autowired
ProjectRepository projectRepository;
#Autowired
ScenarioRepository scenarioRepository;
#Override
#Transactional
public void run() {
List<Project> projectList = projectRepository.findByName("thread test project");
Project project;
project = projectList.get(0);
//A project can have multiple scenarios
Scenario scenario;
if (project.getScenarios().isEmpty()) { //this line fails -> lazyInitializationException - no Session
System.err.println("Creating new scenario");
scenario = new Scenario();
scenario.setName("thread test scenario");
scenario.setDescription(this + ".runServiceFunction at " + System.currentTimeMillis());
scenario.setProject(project);
scenario = scenarioRepository.save(scenario);
} else {
System.err.println("Using existing scenario");
scenario = project.getScenarios().iterator().next();
}
}
}
The Service and Spring TaskExecutor are Autowired in the Controller which is running on a Tomcat v8.0 Server.
Controller code:
#Autowired
ProjectServiceTestThreadImpl testRunnable;
#Autowired
TaskExecutor taskExecutor;
#RequestMapping(value="openproject", method=RequestMethod.GET)
public String getStringProjects(Map<String, Object> model) throws InterruptedException
{
System.err.println(this + " before call to runnable ");
testRunnable.run();
taskExecutor.execute(testRunnable);
return "openproject";
}
The log shows that the database session closes right after the findByName Query:

Can somebody tell me why it does not work this way? I figured out some ways to make it work, but I don't understand why it does not work with the code above. These three approaches correctly insert the Scenario, without closing the database Session in between:
remove #Service from ProjectServiceTestThread and register the bean in the config manually
Not implement Runnable and annotate the run() method of ProjectServiceTestThread with #Async
Not using the Spring Task Executor

I found the issue in my appConfig.java: There was another component scan, which scanned all packages, including services:
#Configuration
#EnableWebMvc
#ComponentScan({"eu.cite"})
public class appConfig extends WebMvcConfigurerAdapter {
this seems to undo the transaction configuration from the xml. I changed the component scan to eu.cite.controller so my servlet is still able to find the controller and does not interfere with the other config
