Error creating bean with name 'entityManagerFactory' defined in br.com.casadocodigo.loja.conf.JPAConfiguration

Boa tarde! Está acontecendo um erro que não consigo prosseguir. Já vi a notificação na net, mas não achei uma solução( usei também o código da aula ocorre o mesmo problema, atualizei o pom.xml.

O código está igual ao da aula, menos o de configuração JPA para conexão com Mysql e o pom.xml que atualizei alguns. Uso Java 1.8, Eclipse Photon, Apache TomCat 8.5

Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class iscom.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary. mai 29, 2019 1:43:42 PM org.apache.catalina.core.ApplicationContext log GRAVE: StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException:

Na sua classe JPAConfiguration, troca:

dataSource.setDriverClassName("com.mysql.jdbc.Driver");

por

dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");

Opa Otávio, Fiz a mudança, mas continuou com a mensagem parecida sobre entitymanager: INFORMAÇÕES: Initializing Spring DispatcherServlet 'dispatcher' mai 29, 2019 6:41:14 PM org.apache.catalina.core.ApplicationContext log GRAVE: StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in br.com.casadocodigo.loja.conf.JPAConfiguration: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.exception.GenericJDBCException: Unable to open JDBC Connection for DDL execution ...

Veja o JPAConfiguration.java

@EnableTransactionManagement
public class JPAConfiguration {

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {

        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();

        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        factoryBean.setJpaVendorAdapter(vendorAdapter);

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUsername("root");
        dataSource.setPassword("123");
        dataSource.setUrl("jdbc:mysql://localhost/casadocodigo");
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        factoryBean.setDataSource(dataSource);

        Properties properties = new Properties();
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        properties.setProperty("hibernate.show_sql", "true");
        properties.setProperty("hibernate.hbm2ddl.auto", "update");

        factoryBean.setJpaProperties(properties);
        factoryBean.setPackagesToScan("br.com.casadocodigo.loja.models");

        return factoryBean;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory emf) {
        return new JpaTransactionManager(emf);
    }


}

Bom dia! Eu coloquei o projeto do aula feito por mim no github: https://github.com/marcelorfranca/casadocodigo

Alguém pode me ajudar com relação ao problema postado acima? Estou usando java 1.8, apache tomcat 8.5.41 e Eclipse Photon. Já fiz várias tentativas com versões do java distinta, apache tom cat anterior/posterior, pom.xml da aula e nada. Não posso passar a aula seguinte com o projeto não funcionando. Percebi também que as configurações do curso são de 2015. Não estaria na hora do Alura atualizar este curso? Cheguei até aqui depois de tanto java. Obrigado
