Boa tarde, o meu projeto não está criando a tabela quando eu rodo o servidor, na hora que eu faço o insert ele diz que a tabela não existe. Ja fiz todas as verificações possiveis, tb repassei os exercicios e nda. Segue abaixo minhas classes de configuração:

JPAConfigurator:

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;

import br.com.casadocodigo.loja.modelo.Produto;

@EnableTransactionManagement
public class JPAConfiguration {

    @Bean
    public LocalContainerEntityManagerFactoryBean EntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
        JpaVendorAdapter jpaVendor = new HibernateJpaVendorAdapter();

        factoryBean.setJpaVendorAdapter(jpaVendor);

        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setUsername("root");
        dataSource.setPassword("cesinhapg");
        dataSource.setUrl("jdbc:mysql://localhost/casadocodigo");
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");

        factoryBean.setDataSource(dataSource);

        Properties prop = new Properties();

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

        factoryBean.setJpaProperties(prop);

        factoryBean.setPackagesToScan(Produto.class.getPackage().getName());

        return factoryBean;

    }

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

    }


}

AppWebConfigurator:

package br.com.casadocodigo.loja.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

import br.com.casadocodigo.loja.controller.HomeController;
import br.com.casadocodigo.loja.dao.ProdutoDAO;

@EnableWebMvc
@ComponentScan(basePackageClasses= {HomeController.class, ProdutoDAO.class})
public class AppWebConfiguration {
    @Bean
    public InternalResourceViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }
}

ProdutoDAO:

package br.com.casadocodigo.loja.dao;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.transaction.Transactional;

import org.springframework.stereotype.Repository;

import br.com.casadocodigo.loja.modelo.Produto;

@Repository
@Transactional
public class ProdutoDAO {

    @PersistenceContext
    private EntityManager em;

    public void gravar(Produto p) {
        em.persist(p);
    }

}

Produto:

package br.com.casadocodigo.loja.modelo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Produto {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    private String descricao;
    private String titulo;
    private int paginas;


    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getDescricao() {
        return descricao;
    }

    public void setDescricao(String descricao) {
        this.descricao = descricao;
    }

    public String getTitulo() {
        return titulo;
    }

    public void setTitulo(String titulo) {
        this.titulo = titulo;
    }

    public int getPaginas() {
        return paginas;
    }

    public void setPaginas(int paginas) {
        this.paginas = paginas;
    }

    @Override
    public String toString() {
        return "Titulo: " + this.titulo + " descriçao: " + this.descricao + " Numero de paginas: "
                + Integer.toString(this.paginas);
    }
}

ServletSpringMVC:

package br.com.casadocodigo.loja.conf;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class ServletSpringMVC extends AbstractAnnotationConfigDispatcherServletInitializer{

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return  null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] {AppWebConfiguration.class, JPAConfiguration.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] {"/"};
    }

}
