Description:
|
Based on a [question|http://stackoverflow.com/questions/13623556/] on stackoverflow, there seem to be use cases for setting message parameters dynamically, e.g. to put a dynamically determined valid value into the message:
{code}
@Future
private Date shippingDate;
{code}
{code}
public class MyFutureValidator implements ConstraintValidator<Future, Date> {
public void initialize(Future constraintAnnotation) {}
public boolean isValid(Date value, ConstraintValidatorContext context) {
Date now = ...;
if( value.after( now ) ) {
context.disableDefaultConstraintViolation();
context
.buildConstraintViolationWithTemplate("Must be after {now}")
.setValue( "now", now )
.addConstraintViolation();
return false;
}
return true;
}
}
{code}
If we don't find enough time for this, we should at least add an {{unwrap()}} method on {{ConstraintValidatorContext}} to allow for provider specific implementations.
