    }

}

Se vc esta utilizando MySql8 faz essas alterações na Class JPAConfigurator

        dataSource.setDriverClass("com.mysql.cj.jdbc.Driver");
        dataSource.setJdbcUrl("jdbc:mysql://localhost:portaDoBancoDeDados/projeto_jpa?useTimezone=true&serverTimezone=UTC");
        dataSource.setUser("root");
        dataSource.setPassword("SenhaBD");

///////////////////////
        Properties props = new Properties();
        props.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL8Dialect");
        props.setProperty("hibernate.show_sql", "true");
        props.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        entityManagerFactory.setJpaProperties(props);
        return entityManagerFactory;

as atualizações das dependências do maven do hibernate q foram atualizadas constam no outro post da uma olhada blz

Sinceramente não achei essas atualizações...

    public DataSource getDataSource() {
        SimpleDriverDataSource dataSource = new SimpleDriverDataSource();

        dataSource.setDriverClass(com.mysql.jdbc.Driver.class);
        dataSource.setUrl("jdbc:mysql://localhost:portaDoBancoDeDados/projeto_jpa?useTimezone=true&serverTimezone=UTC");
        dataSource.setUsername("root");
        dataSource.setPassword("masterkey");

        return dataSource;
    }

tive que usar o SimpleDriverDataSource para usar o setDriverClass? Ta certo mesmo?

    @Bean
    public DataSource getDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        // porta do mysql
        dataSource.setUrl("jdbc:mysql://localhost:3306/projeto_jpa?useTimezone=true&serverTimezone=UTC");
        dataSource.setUsername("root");
        dataSource.setPassword("senhaDoBancoDeDados");

        // ?useTimezone=true&serverTimezone=UTC");

        return dataSource;
    }

da uma olhada no pom.xml e as dependências do maven q eu atualizei.

Ai mano, pegou vei!! Vlw 10!
