Create interface MyCustomValidation and use as default message a message having the same message key name as the name of the just created interface (in our case the default message would be {{

}}).

If you then try to override the default message as follows it will fail:

{{constraintValidatorContext.buildConstraintViolationWithTemplate("some-other-message").addConstraintViolation();
constraintValidatorContext.disableDefaultConstraintViolation();}}
