HV000030: No Validator could be found for Constraint 'javax.validation.constraints.Email' validating type 'java.lang.String'

Question

I’m in a class AdministradorDTO and added some validators to it I found a tutorial on the Internet and I followed the same way in my case it gives this error in the email, before it gave in String too. But then I switched @NotEmpty for @NotNull and it worked.

DTO

package com.dogwalk.dogwalk.dto;

import com.dogwalk.dogwalk.entity.Administrador;
import java.io.Serializable;
import java.util.Date;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotNull;

/**

public class AdministradorDTO implements Serializable {

    private static final long serialVersionUID = 1L;

    private Integer id;
    @NotNull(message = "Preencha o campo Nome")
    private String nome;
    @NotNull(message = "Preencha o campo E-Mail")
    @Email(message = "Email inválido")
    private String email;
    private String senha;
    @NotNull(message = "Preencha o campo Adminstrador Master")
    private boolean master;
    private Date dtGravacao;
    private String userGravacao;

    public AdministradorDTO() {
    }

    public AdministradorDTO(Administrador administrador) {
        this.id = administrador.getId();
        this.nome = administrador.getNome();
        this.email = administrador.getEmail();
        this.master = administrador.getMaster();
        this.dtGravacao = administrador.getDtGravacao();
        this.userGravacao = administrador.getUserGravacao();
    }

    public Integer getId() {
        return id;
    }

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

    public String getNome() {
        return nome;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public boolean isMaster() {
        return master;
    }

    public void setMaster(boolean master) {
        this.master = master;
    }

    public Date getDtGravacao() {
        return dtGravacao;
    }

    public void setDtGravacao(Date dtGravacao) {
        this.dtGravacao = dtGravacao;
    }

    public String getUserGravacao() {
        return userGravacao;
    }

    public void setUserGravacao(String userGravacao) {
        this.userGravacao = userGravacao;
    }

    public String getSenha() {
        return senha;
    }

    public void setSenha(String senha) {
        this.senha = senha;
    }
}

Does anyone know how I can fix this?

Answer 1

How do you own the hibernate-validator in his pom.xml, change the annotation of:

javax.validation.constraints.Email

To:

org.hibernate.validator.constraints.Email

This way Hibernate will provide the appropriate validator that is registered in the application.
