I’m trying to validate some annotated fields, but I can’t bring the messages to the jsp page:

Java user.

mport java.util.Calendar;

import javax.validation.constraints.Email;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class Usuario {

private String nome;
private String sobrenome;
private String cpf;
private String identidade;
@NotNull(message="{usuario.email.nulo}")
@Email(message="{usuario.email.invalido}")
private String email;
@NotNull(message = "{usuario.senha.nula}")
@Size(min = 6, message="{usuario.senha.pequena}")
private String senha;
private Endereco endereco;
private Calendar dataNascimento;

Has a Client class that extends User:

And it has Clientecontroller.java

package br.com.wlsnprogramming.loja.controller;

import javax.servlet.http.HttpSession;
import javax.validation.Valid;

import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;

import br.com.wlsnprogramming.loja.model.usuario.Cliente;

@Controller
@RequestMapping("cliente")
public class ClienteController {

@RequestMapping("login")
public String formLogin() {
    return "cliente/login";
}
@RequestMapping("efetuarLogin")
public String efetuarLogin(@Valid Cliente cliente, BindingResult result, HttpSession session) {
    if(result.hasFieldErrors("email") || result.hasFieldErrors("senha")) {
        System.out.println(result.getFieldError("senha").getDefaultMessage());//Aqui em fiz o teste para ver se recuperava a mensagem, ate aqui deu certo
        return "redirect:login";
    }
    //faz a verificação aqui
    return "redirect:meusPedidos";
}
}

        menuAberto = false;
    }
}

I’ve tried to put everything in the path, but it doesn’t work.

I already discovered the error, it seems you have to redirect on the server side:

return "cliente/login";// direcionando diretamente para o jsp

or

return "forward:login";// direcionado para a função, mas do lado do servidor

You cannot use redirect to redirect on the client side.

-1

Just insert the Spring validation dependency into the project! Spring-Boot-Starter-Validation.

org.springframework.boot spring-boot-Starter-validation 2.4.0

-2

Try to put dependency on pom. Spring boot worked.

org.springframework.boot spring-boot-Starter-validation
