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.

The Keycloak EntityManager can't mapping any model

Keyсloak version 14.0
I have store some custom tables in The Keycloak postgres database, my entity:
public class StoreTestModel {
public StoreTestModel() {
}
public StoreTestModel(Integer id, String fieldOne, String fieldTwo) {
this.id = id;
this.fieldOne = fieldOne;
this.fieldTwo = fieldTwo;
}
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(updatable = false, nullable = false)
private Integer id;
#Column(name = "field_one")
private String fieldOne;
#Column(name = "field_two")
private String fieldTwo;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getFieldOne() {
return fieldOne;
}
public void setFieldOne(String fieldOne) {
this.fieldOne = fieldOne;
}
public String getFieldTwo() {
return fieldTwo;
}
public void setFieldTwo(String fieldTwo) {
this.fieldTwo = fieldTwo;
}
}
When i try to get this data by the EntityManager firts of all I have receive the EntityManager:
EntityManager em = jpaConnectionProvider.getEntityManager();
Then I try to get the data from my custom table:
StoreTestModel storeTestModel = em.createQuery("SELECT u FROM store_test_model u WHERE u.fieldOne = :fieldOne", StoreTestModel.class).setParameter("fieldOne", "test one").getSingleResult();

plese, help me to solve this issue 😢

Can't insert data into database through persistence.xml file

I have created a PostgreSQL script just to insert a row in the customer table. The insert happens when my project is starting to run.
But it doesn't work because I'm getting the following error:

I have already tried using the PostgreSQL script in pgAdmin. And there the script works, but somehow it doesn't work in JPA.. Anyone got a clue how I can solve this problem?

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
Edit - Project entity:

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

Hibernate join error: NullPointerException at org.hibernate.hql.ast.HqlSqlWalker.createFromJoinElement

I create this hql in my project (an snack bar), to search all orders that have the product selected by the user as parameter:
select order from Order order, OrderItem item
inner join order.cod_order_item as item
inner join item.cod_product as cod_product
where cod_product = id
However, when I run the createQuery(), gives a nullpointer at org.hibernate.hql.ast.HqlSqlWalker.createFromJoinElement.
What am i doing wrong?
Below, here's my codes:
OrderDAO.java
public class OrderDAO {
private Session session;
public PedidoDAO(Session session){
this.session = session;
}
public List<Order> getAllOrderFromProduct(Product product{
String hql = "select order from Order order, OrderItem item " +
"inner join order.order_item_id as item " +
"inner join item.product_id as product_id " +
"where product_id = '"+ product.getId() + "'";
Configuration cfg = new Configuration();
SessionFactory factory = cfg.configure().buildSessionFactory();
Session session = factory.openSession();
Query query = session.createQuery(hql);
List result = query.list();
return result;
}
}

Any help is welcome.

I found my error! I forgot to reference the annotation #ManyToMany in relationship table on Order.java, then the Hibernate tried to get the relationship between the two tables and found nothing. Now, works fine with this query, based on #axtavt answer:
select order from Order order, OrderItem item
inner join order.order_item as item
where item.cod_product = id
My Order.java corrected:
#Entity
public class Order{
#Id
#GeneratedValue
private Long order_id;
#Column(name="order_date", nullable=false, length=15)
private Date data;
#Column(name="order_total", nullable=false, length=8)
private double total;
/* Relationships*/
#Column(name="employee_id", nullable=false, length=8)
private Long employee_id;
#Column(name="customer_id", nullable=false, length=8)
private Long customer_id;
#ManyToMany(targetEntity=OrderItem.class, fetch=FetchType.LAZY)
#Fetch(FetchMode.SUBSELECT)
#JoinTable(name = "order_order_item", joinColumns = { #JoinColumn(name = "cod_order") },
inverseJoinColumns = { #JoinColumn(name = "cod_item") })
public Set<OrderItem> setOrderItem = new HashSet<OrderItem>();
public Long getId() {
return order_id;
}
public void setId(Long order_id) {
this.order_id= order_id;
}
public Date getOrderDate() {
return order_date;
}
public void setOrderDate(Date order_date) {
this.order_date = order_date;
}
public double getTotal() {
return total;
}
public void setTotal(double total) {
this.total = total;
}
public Long getFuncionario() {
return cod_funcionario;
}
public void setEmployee(Long employee_id) {
this.employee_id= employee_id;
}
public Long getCustomer() {
return customer_id;
}
public void setCustomer(Long customer_id) {
this.customer_id= customer_id;
}
public Set<OrderItem> getOrderItem() {
return orderItem;
}
public void setOrderItem(Set<OrderItem> orderItem) {
this.orderItem= orderItem;
}
}

You certainly don't need to add OrderItem to from explicitly since it's already added by join:
select order from Order order
inner join order.cod_order_item as item
inner join item.cod_product as cod_product
where cod_product = id
