public class CustomValidator implements Validator {

    private Validator validator;

Answer 1

It appears you only want to validate 2 classes because you want to duplicate the 'confirm password' validation where you have 2 password fields that should match. Instead, why not simply pass an interface to the validator?

public void validate(IPasswordContainer target, Errors errors) {
    if(!target.getConfirm_password().equals(target.getPassword())) {
        errors.rejectValue("confirm_password", "confirm_password.confirm");
    }
}


public boolean supports(Class clazz) {
    return IPasswordContainer.class.equals(clazz);
}
