Erro ao criar tabelas - MYSQL

Boa noite, preciso de uma ajuda com o meu código pois não consigo que as tabelas sejam criadas automaticamente.

package br.com.casadocodigo.loja.conf;

import java.util.Properties;

import javax.persistence.EntityManagerFactory;

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;

@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("admin");
         dataSource.setUrl("jdbc:mysql://localhost:3306/casadocodigo");
         dataSource.setDriverClassName("com.mysql.jdbc.Driver");

         factoryBean.setDataSource(dataSource);

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

         factoryBean.setJpaProperties(props);

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

         return factoryBean;
    }

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

    }

}
