Spring ConstraintViolation not caught - spring

Question

I'm using Spring Boot, and I have created a custom PathVariable validator, which I use as follows:
#GetMapping(value = "/test/{id}")
public ResponseEntity<Void> test(#PathVariable("id")
#Valid
#MyGUID(message = "ID_INVALID")
String id) {
return new ResponseEntity<>(HttpStatus.NO_CONTENT);
}
The validor seems to do its job well - it passes when input is valid, and throws exception when not. The problem is, that my custom exception handler doesn't catch the ConstraintViolationException that is thrown. This is the top line of the stack trace:
javax.validation.ConstraintViolationException: ID_INVALID
Then I have my exeception handler class:
#ControllerAdvice
public class RestExceptionController extends ResponseEntityExceptionHandler {
#ExceptionHandler(value = ConstraintViolationException.class)
public ResponseEntity<ErrorResponse> handleConstraintViolationException(ConstraintViolationException ex,
HttpHeaders headers,
HttpStatus status,
WebRequest request) {
List<String> errorDetailsCodes = new ArrayList<>();
for (ConstraintViolation<?> violation : ex.getConstraintViolations()) {
errorDetailsCodes.add(violation.getMessage());
}
ErrorResponse errorResponse = new ErrorResponse(
status.name(),
status.value(),
ex.hashCode(),
errorDetailsCodes
);
logException(ex);
return new ResponseEntity<>(errorResponse, headers, status);
}
#ExceptionHandler(value = Exception.class)
public ResponseEntity<ErrorResponse> handleGeneralException(Exception ex) {
ErrorResponse errorResponse = new ErrorResponse(
HttpStatus.INTERNAL_SERVER_ERROR.name(),
HttpStatus.INTERNAL_SERVER_ERROR.value(),
ex.hashCode()
);
logException(ex);
return new ResponseEntity<>(errorResponse, HttpStatus.INTERNAL_SERVER_ERROR);
}
}
It is strange to me that despite the fact I have both a specific and a general exception handler, they are both skipped, and the system throws its own error:
{
"timestamp": 1568554746642,
"status": 500,
"error": "Internal Server Error",
"message": "ID_INVALID",
"path": "/api/logged-in-user/test/123"
}
How can I catch this exception and return my custom response?
Thanks.
