Estou usando mysql 8 portanto tive q mexer algumas configurações do meu pom.xml, talvez esteja faltando alguma coisa. Segue o pom e o JPAConfiguration.java. OBS: não há nenhum erro logado no log do servidor

package br.com.casadocodigo.loja.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.JpaVendorAdapter;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.persistence.EntityManagerFactory;
import java.util.Properties;

@EnableTransactionManagement
public class JPAConfiguration {

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

        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();

        factoryBean.setJpaVendorAdapter(vendorAdapter);

        DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
        driverManagerDataSource.setUsername("root");
        driverManagerDataSource.setPassword("root");
        driverManagerDataSource.setUrl("jdbc:mysql://localhost:3306/casadocodigo?useSSL=false&serverTimezone=UTC");
        driverManagerDataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");

        factoryBean.setDataSource(driverManagerDataSource);

        Properties properties = new Properties();

        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        properties.setProperty("hibernate.show_sql", "true");
        properties.setProperty("hibernate.hbm2dll.auto", "update");

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

        return factoryBean;
    }

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

Oi Jeison,

Tem um erro nessa linha:

properties.setProperty("hibernate.hbm2dll.auto", "update");

Na verdade a propriedade é hbm2ddl, com dois D e não dois L.

Faça a correção e veja se resolve.

Ah era isso mesmo! Eu olhei um monte de vezes a configuração e não tinha visto isto. Muito obrigado!
