org.hibernate.cfg.Configuration adding packages where Annotated classes resides

I am creating database tables by the following code:

public void createSchema() {
    Configuration configuration = new Configuration();
    configuration.setProperty("hibernate.connection.driver_class", driverClassName);
    configuration.setProperty("hibernate.connection.url", url);
    configuration.setProperty("hibernate.connection.username", username);
    configuration.setProperty("hibernate.connection.password", password);
    configuration.setProperty("hibernate.dialect", hibernateDialect);

    configuration.addAnnotatedClass(Base.class);
    configuration.addAnnotatedClass(User.class);
    logger.info("begin database schema creation =========================");
    new SchemaUpdate(configuration).execute(true, true);
    logger.info("end database schema creation ===========================");
}

Here I have specified the Annotated classes names by configuration.addAnnotatedClass method. If I have 50 classes, then it will be really messy.

Is there any way to specify packages names for scanning for Annotated classes?

You can use Reflections to load all the Entities which are annotated as @Entity and add them to hibernate configuration. Chech the link fir a sample code Hibernate 4 Annotation Configuration

I'm not familiar with many of the changes in Hibernate 4, but there was no way to do this in Hibernate 3. I recommend using Spring's excellent Hibernate support, which lets you scan packages for entities, like you're asking for, and can manage a lot of other stuff for you, too, if you run your app in a Spring container.
