If I have a validation annotation like this:



and a ValidationMessage.properties file like this:



Is it possible to interpolate the invalid value (e.g. '{value}') of the ConstraintViolation into the message? It seems only annotation based parameters, e.g. '{min}' and '{max}' can be interpolated. The same question would apply to the path of the failing property, e.g. '{path}'.

The resulting error message should be
"Invalid name 'A', should be from 2 to 50 characters"

I'm using 4.0.2 GA.

Thanks,

Hi Jeroen,

The Bean Validation spec does not include value interpolation in the definition of the MessageInterpolator algorithm. Maybe partly because one cannot guarantee that the validated object has a valid toString implementation.

The only way to achieve what you want is to write your own MessageInterpolator and then use the MessageInterpolator.Context.getValidatedValue() to get hold of the validated value. You can then use this value to do your own message interpolation. Have a look at ResourceBundleMessageInterpolator to see how to write a MessageInterpolator.

Btw, this won't help you to get the path interpolated though.
