Dynamic error messages

Hi all,

Apologies if this has been answered before but a quick search didn't resolve my issue.

My questions is: If you take the CheckCaseValidator example in Chapter 3 of the Hibernate Validator 4.2 documentation, is it possible to display the actual string being validated in the error message? I can see from section 3.1.3 that is it possible to dynamically display a constraint in the error message but what about the object being validated?

I am using Hibernate Validator 4.2.0.Final and Spring 3.0.5.Release's LocalValidatorFactoryBean to do the bootstrapping.

Thanks,
Mark

Hi Mark,

You can use Hibernate Validator's ValueFormatterMessageInterpolator:

Code:

Configuration<?> configuration = Validation.byDefaultProvider().configure();
ValidatorFactory factory = configuration
    .messageInterpolator(new ValueFormatterMessageInterpolator(configuration.getDefaultMessageInterpolator()))
    .buildValidatorFactory();

Validator validator = factory.getValidator();

This interpolator allows to displa the validated value within messages using the expression ${validatedValue}. You can learn more in the reference guide:

http://docs.jboss.org/hibernate/validator/4.2/reference/en-US/html/validator-bootstrapping.html#section-message-interpolator
