Pessoal alguém poderia ajudar a resolver esse problema, não consigo encontrar o erro, já exclui a pasta m2 fiz update do maven mas não deu em nada. Se alguém puder me ajudar agradeço.

Segue minhas classes

ProdutoDao:

package br.com.casadocodigo.loja.daos;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

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


@Repository
@Transactional
public class ProdutoDao {

    @PersistenceContext
    private EntityManager manager;

    public void gravar(Produto produto){
    manager.persist(produto);    
    }

}

JPAConfiguration:

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 jpaVendorAdapter = new HibernateJpaVendorAdapter();

        factoryBean.setJpaVendorAdapter(jpaVendorAdapter);

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUsername("root");
        dataSource.setPassword("");
        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;
    }

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



}

ProdutosController

package br.com.casadocodigo.loja.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import br.com.casadocodigo.loja.daos.ProdutoDao;

@Controller
public class ProdutosController {


    @Autowired
    private ProdutoDao dao;

    @RequestMapping("/produtos/form")
    public String form(){
        return "produtos/form";
    }


    @RequestMapping("/produtos")
    public String grava(Produto produto){
        dao.gravar(produto);    
        System.out.println(produto);

        return "produtos/ok";


    }

}

AppWebConfiguration

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;

Olá. tudo bem ?

Pelo erro, aparentemente ele não está conseguindo abrir uma conexão com o banco de dados.

Os dados que você está passando estão corretos para abrir a conexão ?
