By executing a simple program of Spring Hibernate integration, I am getting following issue

Question

I've got some exceptions in my maven-spring-hibernate project. I think the trouble is in my springg.xml file, but I don't understand where.

Main class

package org.db;
import org.hibernate.Query;
import org.model.*;
import java.sql.SQLException;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {
    public static void main(String[] args) throws SQLException {
                ApplicationContext context =
                new ClassPathXmlApplicationContext("springg.xml");
        SessionFactory sessionFactory = (SessionFactory) context.getBean("sessionFactory");
        Session session = sessionFactory.openSession();
        User user = new User("1234","222");
        session.save(user);

        session.flush();


        session.close();
}

Answer 1

Remove all the <version> tag of your dependencies and let the Spring manage the versions.

Answer 2

In my case it was caused by different versions of hibernate libraries (copy-paste)

implementation 'org.hibernate:hibernate-validator:6.1.6.Final'
implementation 'org.hibernate:hibernate-core:5.4.27.Final'

So double check that you use same versions

Answer 3

You are missing hibernate-core library.

Add this to yours pom configuration:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.0.1.Final</version>
</dependency>
