Li Na has been asked to create a Web application, in which she has to integrate the Spring framework with Hibernate. To do this, Li Na has to configure the SessionFactory object in the Spring configuration file. For this, she has created a Spring configuration file named Spring-Hibernate.xml. Which of the following code snippets should she use to configure the SessionFactory object?@Beanpublic SessionFactoryBean sessionFactory(){create session factorysSessionFactoryBean sessionFactory = new SessionFactoryBean();A// set the propertiessessionFactory.setDataSource(myDataSource());sessionFactory.setPackagesToScan(env.getProperty("hibernate.packagesToScan"));sessionFactory.setHibernateProperties(getHibernateProperties());return sessionFactory;

Li Na should use the following code snippet to configure the SessionFactory object in the Spring configuration file:

@Bean
public SessionFactory sessionFactory() throws Exception {
   LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
   sessionFactory.setDataSource(myDataSource());
   sessionFactory.setPackagesToScan(env.getProperty("hibernate.packagesToScan"));
   sessionFactory.setHibernateProperties(getHibernateProperties());
   sessionFactory.afterPropertiesSet();
   return sessionFactory.getObject();
}

This code snippet creates a LocalSessionFactoryBean object and sets its properties using the `setDataSource`, `setPackagesToScan`, and `setHibernateProperties` methods. It then calls the `afterPropertiesSet` method to initialize the SessionFactory object, and returns it using the `getObject` method.

Note that the `sessionFactory` method should throw an exception of type `Exception`, as the `afterPropertiesSet` method may throw an exception during initialization.
