Проблема передачи настроек в LocalEntityManagerFactoryBean

Есть вот такой класс

Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "web")
@PropertySource("classpath:db.properties")
public class HibernateConfig {

    @Autowired
    private Environment env;

    @Bean
    public LocalEntityManagerFactoryBean entityManagerFactory() {
        LocalEntityManagerFactoryBean factoryBean = new LocalEntityManagerFactoryBean();

        Properties props=new Properties();
        props.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
        props.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
        props.put("hibernate.dialect",env.getProperty("hibernate.dialect"));
        props.put("javax.persistence.jdbc.url",env.getProperty("db.url"));
        props.put("javax.persistence.jdbc.user",env.getProperty("db.username"));
        props.put("javax.persistence.jdbc.password",env.getProperty("db.password"));
        props.put("javax.persistence.jdbc.driver",env.getProperty("db.driver"));
        return factoryBean;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory);
        return transactionManager;
    }
}

Не могу найти как передать мой Properties в factoryBean

Файл db.properties
