We can implement a solid validation that made our backend more resilient to bad inputs coming from users. Throughout the tutorial, we used predefined validation rules, but we can also create our custom validation rule for a specialized use case\

Using JavaX. Validation package or hibernate Validators

package com.tericcabrel.hotel.models.dtos;

import com.tericcabrel.hotel.models.Address;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Pattern.Flag;
import lombok.Data;

@Data
public class AddressDto {
  @NotBlank(message = "The country is required.")
  private String country;
  
  @NotBlank(message = "The city is required.")
  private String city;
  
  @NotBlank(message = "The Zip code is required.")
  @Pattern(regexp = "^\\d{1,5}$", flags = { Flag.CASE_INSENSITIVE, Flag.MULTILINE }, message = "The Zip code is invalid.")
  private String zipCode;
  
  @NotBlank(message = "The street name is required.")
  private String street;
  
  private String state;
  
  public Address toAddress() {
    return new Address()
        .setCountry(country)
        .setCity(city)
        .setZipCode(zipCode)
        .setStreet(street)
        .setState(state);
  }
}
