Spring Boot - java.lang.ClassNotFoundException: org.hibernate.engine.transaction.spi.TransactionContext

Question

I am new on Spring Boot. I am trying make a web app using Hibernate but I am experiencing these errors. I looked similar questions but I couldn't find a solution. How can I solve it?

I have solved it. I have removed this part my config class and it's solved.

  @Bean
  public HibernateTransactionManager transactionManager() {
    HibernateTransactionManager transactionManager = 
        new HibernateTransactionManager();
    transactionManager.setSessionFactory(sessionFactory().getObject());
    return transactionManager;

Try adding these dependencies to the dependencies section of your pom and rebuilding your project:

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
    </dependency>

Usually with spring boot and hibernate you build the sessionFactory. So, you do not need the transactionManager bean.

Therefore remove this part from your DBConfiguration:

@Bean
public HibernateTransactionManager transactionManager() {
    HibernateTransactionManager transactionManager = new HibernateTransactionManager();
    transactionManager.setSessionFactory(sessionFactory().getObject());
    return transactionManager;
}
