How to connect a base in Java using annotations?

Question

Java

Good afternoon! Created a database connection in the Wildfly 10 application server with a JNDI name
java:jboss/datasources/PostgreDataSource
I found on the Internet that you can connect to the database by setting up the persistence.xml file like this:

<persistence-unit name="Unit1" transaction-type="JTA"> 
        <jta-data-source>java:jboss/datasources/PostgreDataSource</jta-data-source> 
        <properties> 
            <property name="hibernate.hbm2ddl.auto" value="update"/> 
        </properties> 
    </persistence-unit>

And how can you connect this database using annotations, without the help of the persistence.xml file?
Now the configuration file looks like this:

@Configuration
@EnableTransactionManagement
@ComponentScan({ "net.myProg" })
@PropertySource(value = { "classpath:application.properties" })
@EnableJpaRepositories("net.myProg.repository")
public class HibernateConfiguration {

    @Autowired
    private Environment environment;

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
        entityManagerFactoryBean.setPackagesToScan("net.myProg.model");

        entityManagerFactoryBean.setJpaProperties(hibernateProperties());

        return entityManagerFactoryBean;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());

        return transactionManager;
    }
  
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
//        dataSource.setDriverClassName("org.postgresql.Driver");
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        //Lazy load initializayion. Hibernate сам открывает сессию для получения lazy объекта, если это нужно
        properties.put("hibernate.enable_lazy_load_no_trans", environment.getRequiredProperty("hibernate.enable_lazy_load_no_trans"));
//        properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
        return properties;
    }

    @Bean
    public PersistentTokenRepository persistentTokenRepository() {
        JdbcTokenRepositoryImpl db = new JdbcTokenRepositoryImpl();
        db.setDataSource(dataSource());
        return db;
    }
    
}
