I'm trying to apply validations to my Spring Boot project but they're not being applied. I'm trying to display an error message below the text area indicating the error that's occurring in the form. However, when I fill out the form, it completely ignores my restrictions.
Attached code: My object's looks like this:
package com.erphotel.personManagement.domain;
import jakarta.persistence.\*;
import jakarta.validation.constraints.NotBlank;
import jakarta.validation.constraints.NotNull;
import jakarta.validation.constraints.Pattern;
import java.io.Serializable;
import lombok.Data;
@Data
@Entity
@Table(name = "persons")
public class PersonDomain implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long person_id;
@NotBlank(message = "El nombre es obligatorio")
private String name;
@NotNull(message = "El apellido es obligatorio")
private String surname;
@Pattern(regexp = "^\[0-9\]{9}$", message = "Por favor, introduce un número de teléfono válido (9 dígitos)")
private String phone_number;
@Pattern(regexp = "^\[0-9\]{8}\[A-Za-z\]$", message = "Por favor, introduce un DNI válido (8 dígitos y 1 letra)")
private String dni;
}
My controller's action looks like this:
@PostMapping("/savePersona")
public String guardarPersona(@Valid @ModelAttribute("persona") PersonDomain persona, @AuthenticationPrincipal User username,
BindingResult result) {
if (result.hasErrors()) {
return "redirect:/newPerson";
}
personService.salvar(persona);
return "redirect:/person";
}
My HTML looks like this:

ERROR LOG:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

I have searched a few pages and most of them indicate that the errors are related to the POM, but I have it updated and it still doesn't work. I have also tried some code from internet pages and nothing works. Previously, I had this done with a script, but I prefer to do it with validation and I would like to know where my error is.
Thanks in advance.
