Solution: If you see above exception it means you are not loading configuration from AnnotationConfiguration please load your configuration as below:

return new AnnotationConfiguration().configure().buildSessionFactory();

For loading configuration from XML file we use below code:

return new Configuration().configure().buildSessionFactory();
