Validation error with Spring MVC in nested Entity

And, well, how are you? I started studying Spring recently for AlgaWorks courses and the progress of the course I came across a problem in a project that I am developing.

I have a School entity that has the following characteristics:

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

@NotNull(message = "Código INEP é obrigatório")
@Column(name = "codigo_inep", unique = true)
private Integer codigoINEP;

@NotEmpty(message = "Nome é obrigatória")
@Size(max = 100, message = "O nome não pode conter mais de 100 caracteres")
@Column(length = 100, nullable = false)
private String nome;

@Column(name = "telefone", length = 16)
private String telefone;

@Column(name = "celular", length = 16)
private String celular;

@Email(message = "E-mail inválido")
@Column(length = 80)
private String email; 

And my entity Address is as follows:

@NotEmpty(message = "Logradouro é obrigatório")
@Column(length = 80)
private String logradouro;

@Column(length = 10)
private String numero;

@Column(length = 80)
private String complemento;

@NotEmpty(message = "Bairro é obrigatório")
@Column(length = 60)
private String bairro;

@NotEmpty(message = "Município é obrigatório")
@Column(length = 60, nullable = false)
private String municipio;

@NotEmpty(message = "CEP é obrigatório")
@Column(length = 10)
private String cep;

@Enumerated(EnumType.STRING)
@Column(length = 2, nullable = false)
private Uf uf;

@Enumerated(EnumType.STRING)
@Column(length = 8)
private Localizacao localizacao;

@Column(length = 60)
private String distrito;

In my control the mapped method to access the SchoolCooker view is as follows:

@RequestMapping("/nova")
public ModelAndView nova() {

    ModelAndView mv = new ModelAndView(CADASTRO_VIEW);
    Escola escola = new Escola();
    escola.setEndereco(new Endereco());
    mv.addObject(escola);

    return mv;
}

And the mapped method to save looks like this:

@RequestMapping(method = RequestMethod.POST)
public String salvar(@Validated Escola escola, Errors erros, RedirectAttributes attributes) {

    if (erros.hasErrors()) {
        return CADASTRO_VIEW;
    }

    escolas.save(escola);

    attributes.addFlashAttribute("mensagem", "Escola salva com sucesso!");

    return "redirect:/escola/nova";
}

I used this code snippet to list the errors in my View CadastroEscola:

<div class="alert alert-danger" th:if="${#fields.hasAnyErrors()}">

    <div th:each="detailedError : ${#fields.detailedErrors()}">
        <span th:text="${detailedError.message}"></span>
    </div>

</div>

And this attribute in each input to leave the input red if it has any validation error:

<div class="form-group" th:classappend="${#fields.hasErrors('nome')} ? 'has-error'" >

                    <label for="nome" class="col-sm-2 control-label" >Nome</label>

                    <div class="col-sm-4" >
                        <input type="text" class="form-control" id="nome" th:field="*{nome}" placeholder="Informe o seu nome" />
                    </div>

                </div>

In the input name, if you do not enter any value, the error appears and the field is red, but in the input cep below it does not appear,

<div class="form-group" th:classappend="${#fields.hasErrors('endereco.cep')} ? 'has-error'" >

                    <label for="cep" class="col-sm-2 control-label"  >CEP</label>

                    <div class="col-sm-2" >
                        <input type="text" class="form-control js-cep" id="cep" th:field="*{endereco.cep}" placeholder="00000-000" />
                    </div>

                </div>

How do I get these validation errors from the School entity and display on my page, thank you already. Vlw guys.
