Estou lendo a apostila FJ28, e tive alguns problemas com a criação do ProdutosController..
Ele não apresenta nenhum erro, apenas não acessa a página...

Segue o código abaixo:

package br.com.caelum.goodbuy.modelo;

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

@Entity
public class Produto
{
	@Id
	@GeneratedValue
	private Long id;

	private String nome;

	private String descricao;

	private Double preco;

	public Long getId()
	{
		return id;
	}

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

	public String getNome()
	{
		return nome;
	}

	public void setNome(String nome)
	{
		this.nome = nome;
	}

	public String getDescricao()
	{
		return descricao;
	}

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

	public Double getPreco()
	{
		return preco;
	}

	public void setPreco(Double preco)
	{
		this.preco = preco;
	}

}

package br.com.caelum.goodbuy.dao;

import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
import br.com.caelum.goodbuy.infra.CriadorDeSession;
import br.com.caelum.goodbuy.modelo.Produto;
import br.com.caelum.vraptor.ioc.Component;

@Component
public class ProdutoDao
{
	private final Session session;

	public ProdutoDao()
	{
		this.session = CriadorDeSession.getSession();
	}

	public void atualiza(Produto produto, Session session)
	{

		Transaction tx = session.beginTransaction();
		session.update(produto);
		tx.commit();
	}

	public void exclui(Produto produto, Session session)
	{

		Transaction tx = session.beginTransaction();
		session.delete(produto);
		tx.commit();
	}

	public void salva(Produto produto)
	{

		Transaction tx = session.beginTransaction();
		session.save(produto);
		tx.commit();

	}

	public List<Produto> listaTudo()
	{
		return this.session.createCriteria(Produto.class).list();
	}

}

package br.com.caelum.goodbuy.controller;

import java.util.List;
import javax.annotation.Resource;
import br.com.caelum.goodbuy.dao.ProdutoDao;
import br.com.caelum.goodbuy.modelo.Produto;

@Resource
public class ProdutosController
{

	private final ProdutoDao dao;

	public ProdutosController(ProdutoDao dao)
	{
		this.dao = dao;
	}

	public List<Produto> lista()
	{
		return dao.listaTudo();
	}
}
E o erro:

O problema no erro anterior era o import da @Resource, mas agora já coloquei o import certo… e o erro agora é o seguinte:
