E aí, Lorran! Beleza? =)

Você lembrou de fazer a alteração na classe ServletSpringMVC? No método getServletConfigClasses(), você precisa adicionar a classe JPAConfiguration, para que o Spring reconheça aquela classe como configuração. =)

Se você tiver lembrado de fazer isso e, ainda assim não estiver funcionando, posta aqui o código da sua JPAConfiguration, por favor. =)

Classe: ServletSpringMVC

package br.com.casadocodigo.loja.conf;

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

public class ServletSpringMVC extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        // TODO Auto-generated method stub
        return null;
    }

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

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

}

Classe: JPAConfiguration

package br.com.casadocodigo.loja.conf;

import java.util.Properties;

import org.springframework.context.annotation.Bean;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
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("123");
        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.auto", "update");

        factoryBean.setJpaProperties(props);

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

        return factoryBean;
    }
}
solução!

Descobri o que era:

Esqueci d implementar o método na JPAConfiguration.

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