Estou com o seguinte problema:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pessoaController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private br.com.esc.daos.PessoaDAO br.com.esc.controllers.PessoaController.pessoaDAO; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [br.com.esc.daos.PessoaDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Seguem minhas classes:

PessoaController:

@Controller
public class PessoaController {

    @Autowired
    private PessoaDAO pessoaDAO;

    @RequestMapping("/")
    public String index(){
        System.out.println("Entrando na home da CDC");
        return "index";
    }

    @RequestMapping("/cadastro")
    public String cadastro(){

        return "cadastro";
    }

    @RequestMapping("/cadastroPessoa")
    public String cadastroPessoa(Pessoa pessoa){
        pessoaDAO.cadastrar(pessoa);
        return "cadastro-sucesso";
    }

}

Quais outras classes devo colocar para analise?

Ola Rafael,

A exception nos diz que ele nao conseguiu criar a classe PessoaDAO, que esta como Autowired, poderia postar sua classe para podermos olhar?

Aqui esta a PessoaDAO:

@Repository
@Transactional
public class PessoaDAO {

    @PersistenceContext
    private EntityManager manager;

    public void cadastrar(Pessoa pessoa){
        manager.persist(pessoa);
    }

    public void atualizar(Pessoa pessoa){        
        manager.merge(pessoa);
    }

    public List<Pessoa> listaTodasPessoas(){
        Query q = manager.createQuery("select p from Pessoa p");        
        List<Pessoa> pessoas = q.getResultList();
        return pessoas;
    }

    public boolean existe(Pessoa pessoa) {

        String consulta = "select u from Pessoa u where u.nomeUsuario = :pUsuario and u.senhaUsuario = :pSenha";
        Query query=manager.createQuery(consulta);

        query.setParameter("pUsuario", pessoa.getNomeUsuario());
        query.setParameter("pSenha", pessoa.getSenhaUsuario());

        try {
            Pessoa resultado = (Pessoa) query.getSingleResult();
        } catch (NoResultException ex) {
            return false;
        }
        return true;
    }

    public Pessoa pessoaLogada(Pessoa pessoa) {

        Pessoa resultado = new Pessoa();

        String consulta = "select u from Pessoa u where u.nomeUsuario = :pUsuario";
        Query query=manager.createQuery(consulta);        

        query.setParameter("pUsuario", pessoa.getNomeUsuario());        

        try {
            resultado = (Pessoa) query.getSingleResult();
        } catch (NoResultException ex) {
            return null;
        }catch (NonUniqueObjectException e) {
            return null;
        }
        return resultado;
    }

    public void removerPessoa(Pessoa pessoa){
        manager.find(Pessoa.class, pessoa.getId());
        manager.remove(pessoa);
    }

}
solução!

Faltava adicionar PessoaDAO.class a AppWebConfiguration

@ComponentScan(basePackageClasses={PessoaController.class, PessoaDAO.class})
