Validate all fields at once using hibernate validator

I'm using Spring Boot 2.2.0 to build a restful service with the java bean validation framework. Hibernate-Validator is used behind the scenes. The validation works well but throws an exception after one field fails to match the constraint. I would like to validate all fields first and then give the consumer a response with all errors. Is that possible?

Assuming you use @Valid annotation on your request, there is a MethodArgumentNotValidException that you could use in an @ExceptionHandler method in order to achieve that.

@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(MethodArgumentNotValidException.class)
public List<String> handleValidationExceptions(MethodArgumentNotValidException ex) {
    //get All errors with
    ex.getBindingResult().getAllErrors();
    //and map them
}
