I have the following class:

import org.hibernate.validator.constraints.NotBlank;

@Entity
@Table(name = "geracao")
public class Geracao {

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

    @NotBlank(message = "Nome não pode estar em branco.")
    @Pattern(regexp = "[A-z]*", message = "Atenção, digite somente letras")

    @Column(length = 20, nullable = false)
    private String nome;

    @NotBlank
    @Pattern(regexp = "[0-9]*", message = "Atenção, digite somente números")
    private Integer numero;

    @OneToMany(mappedBy = "geracao", fetch = FetchType.LAZY)
    private Collection<Habilidade> habilidades;

    public Geracao() {

    }

    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 void setHabilidades(Collection<Habilidade> habilidades) {
        this.habilidades = habilidades;

And my method record:

public void gravar() {
        try {
            if (geracao.getId() == null) {
                dao.insert(geracao);
                MensagensUtil.sucesso("Geração " + geracao.getNome() + " cadastrado(a) com sucesso!");
                geracao = new Geracao();
            } else {
                dao.update(geracao);
                MensagensUtil.sucesso("Geração " + geracao.getNome() + " atualizado(a) com sucesso!");
                // lista = dao.findByName(arg);
            }

        } catch (Exception e) {
            MensagensUtil.erro(e.getMessage());
            return;
        }

    }

When I try to make a new registration nothing happens on the screen and in my log I have the following error message:

17:52:52,620 SEVERE [javax.enterprise.Resource.webcontainer.jsf.context] (default task-4) javax.validation.Unexpectedtypeexception: HV000030: No Validator could be found for Constraint 'javax.validation.constraints.Pattern' validating type 'java.lang.Integer'.

Your mistake is simple. See in your entity:

@Pattern(regexp = "[0-9]*", message = "Atenção, digite somente números")
private Integer numero;

The annotation @Pattern shall not be used in fields of type Integer. The reason is because it doesn’t make sense. There’s no such thing as yours Integer have anything other than a number that can trigger your validation message.

Therefore, the solution would be one of the following:

  • Take out the annotation @Pattern. If you want, use the notes @Max and/or @Min to delimit the desired numbers, such as this example:

    @Min(value = 1, message = "Atenção, digite somente números de 1 a 721")
@Max(value = 721, message = "Atenção, digite somente números de 1 a 721")
private Integer numero;

  • Change the field type as well as the getter and Setter to String.

In addition, the annotation @NotBlank also cannot be used in fields of type Integer. So if you prefer the first option, remove it as well.

  • I discovered this by giving a researched further sinking, but it was just that. Thank you very much.
