Is it possible to ignore a custom validation annotation to be ignored?

I am using Spring 4 and Hibernate 5

I have a user class with a password field with a custom validator.

I need to test it while the form binding should be 8 characters long and contain lowercase and uppercase letters and numbers.

When the user enters the password, it is valid, but it is invalid when I encode it.

So, is there a way for custom validation annotations to be ignored with persistence?

I know I can make another field for the plaintext password, or make a data transfer object, validate it, and then transfer the data to the user. But I'm interested in the ability to parameterize the annotation.

@Entity
@Table(name = "user")
public class User { 
//other fields

@NotNull
@NotEmpty
@ValidPassword
@Column(name = "password", nullable = false, length = 60)
private String password;
//getters and setters 
}

      

        
        
        
      

    

My validator

@Target({ TYPE, FIELD, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = PasswordValidator.class)
@Documented
public @interface ValidPassword {
String message() default "Password is too short! Must be 8 digits and    include lowercase, uppercase letters and numbers.";

Class<?>[] groups() default {};

Class<? extends Payload>[] payload() default {};
}

      

        
        
        
      

    

and

public class PasswordValidator implements ConstraintValidator<ValidPassword, String> {

private Pattern pattern;
private Matcher matcher;
private static final String PATTERN = "((?=.*\\d)(?=.*[a-z])(?=.*[A-Z]).{8,})";

@Override
public void initialize(ValidPassword constraintAnnotation) {
}

@Override
public boolean isValid(String password, ConstraintValidatorContext context) {
    return (validate(password));
}

private boolean validate(String password) {
    pattern = Pattern.compile(PATTERN);
    matcher = pattern.matcher(password);
    return matcher.matches();
}
}

      

        
        
        
      

    

Controller method

@RequestMapping(value = "/registeruser", method = RequestMethod.POST)
public String registerUser(@ModelAttribute("user") @Valid User user, BindingResult result, Model model) {
    if (result.hasErrors()) {
        model.addAttribute("errorSummary", result.getFieldErrors().stream()
                .map(e -> e.getField() + " error - " + e.getDefaultMessage() + " ").collect(Collectors.toList()));
        model.addAttribute("user", user);

    } else {
        User registered = null;
        registered = createUserAccount(user, result);

        if (registered == null) {
            model.addAttribute("errorSummary", "User with this email already registered!");
            model.addAttribute("user", user);
            return "registration";
        }
        model.addAttribute("flashMessage", "User registered successfully!");
    }

    return "registration";
}

      

        
        
        
      

    

UserService implementation method (where I encode my password)

@Transactional
@Override
public User registerNewUserAccount(User user) throws EmailExistsException {

    if (emailExist(user.getEmail())) {
        throw new EmailExistsException("There is an account with that email address:" + user.getEmail());
    }

    if (user.getPassword() == null) {
        user.setPassword(new BigInteger(130, new SecureRandom()).toString(32));
        System.out.println("+++++++++++++++" + user.getPassword());
    }
    user.setPassword(passwordEncoder.encode(user.getPassword()));
    user.setUserRole(new HashSet<UserRole>(1));
    user.getUserRole().add(new UserRole(user, Constants.RoleType.USER.name()));
    save(user);
    return user;
}
