How do I dynamically resolve message attribute value with Spring Validator JSR 303?

I'm using Spring Validator (JSR 303) with annotation and would like to resolve the attribute (idEnveloppe) value in an error message. Consider this simple scenario: 

@NotEmpty(message = "GCE-COT-DTC-RJFLX03 La donnée &idEnveloppe du bloc entête du flux de cotisation DSN n'est pas renseignée")
@NotNull(message = "GCE-COT-DTC-RJFLX03 La donnée &idEnveloppe du bloc entête du flux de cotisation DSN n'est pas renseignée")
@Pattern(regexp = "[0-9]{14}", message = "GCE-COT-DTC-RJFLX04 La donnée '${idEnveloppe}' du bloc entête du flux de cotisation DSN n'est pas valide}")
private String idEnveloppe;

print error:

private BindingResult bindAndValidate(final DsnCotFluxDto item) {

    DataBinder binder = new DataBinder(item);
    binder.setValidator(validator);
    binder.validate();
    // LOG.error(binder.getErrors().getBindingResult().toString());

    return binder.getBindingResult();

}

/**
 * Etude du cas des erreurs
 * @param results résultat des validations
 * @param item
 * @throws BusinessException
 */
private void buildValidationException(final BindingResult results, final DsnCotFluxDto item) throws BusinessException {
    StringBuilder msg = new StringBuilder();
    String code;
    String message;
    String rejectedValue;


    for (ObjectError error : results.getAllErrors()) {

        code = error.getDefaultMessage().substring(0, 19);
        message = error.getDefaultMessage().substring(20);
        // rejectedValue = error.getObjectName().getRejectedValue();

        msg.append("\n\t  \t---Error code : -- " + code + " ---Error message : --" + message + "\n");
        LOG.warn("\n\t  \t---Error code : -- " + code + " ---Error message : --" + message + "\n");
    }

    // throw new ValidationException(msg.toString());
}

Thank you

i get them with this

 rejectedValue = ((FieldError) error).getRejectedValue().toString();

After i insert them in the message string like:

  message = new StringBuilder(message).insert(10, rejectedValue).toString();

and it work fine

Thank you

Here is the quote from documentation:

As of Hibernate Validator 5 (Bean Validation 1.1) it is possible to use the Unified Expression Language (as defined by JSR 341) in constraint violation messages. [...] The validation engine makes the following objects available in the EL context:

  • the currently validated value (property, bean, method parameter etc.) under the name validatedValue

So, try the following:

@Pattern(regexp = "[0-9]{14}", message = "GCE-COT-DTC-RJFLX04 La donnée '${validatedValue}' du bloc entête du flux de cotisation DSN n'est pas valide}")
