Сообщения об ошибках Optaplanner с использованием Contraints.drl с Spring Boot

Я использую optaplanner 8.3.0 с optaplanner-spring-boot-starter, и я использую файл constraints.drl. В предыдущих версиях ошибки drl были довольно четкими и имели номера строк и т. Д.

В этой конфигурации я получаю такие сообщения журнала, как:

Типизированное выражение Ввод: drlxExpr = volume, patternType = class com.drift.excelsgl.domain.planning.ExpectedTankLevel, declrations = []

...

Есть ли способ проверить файл drl, который возвращает старые сообщения?

И когда файл drl загружается, я получаю код, сгенерированный из файла drl, который выглядит как 16 раз подряд. Это сбивает с толку.   -  person elk-tamer    schedule 17.03.2021

Да, сообщения об ошибках DRL слишком подробны и слишком мало подробны. Переключитесь на ConstraintStreams (также использует Drools под обложками) с последней версией - там гораздо лучше сообщения об ошибках.   -  person Geoffrey De Smet    schedule 18.03.2021

Могут ли ConstraintStreams соответствовать всем ограничениям, которые выполняют правила drl? Я пробовал их около года назад, и мне показалось, что они не могут. Может пора попробовать еще раз.   -  person elk-tamer    schedule 18.03.2021

Какой конструкции вам не хватало? Прямо сейчас, только последовательные n смен подряд все еще сложно, но это в стадии разработки.   -  person Geoffrey De Smet    schedule 18.03.2021

Просто java.lang.IllegalStateException: There is an error in a scoreDrl or scoreDrlFile. действительно бесполезен. Обычно это исключение должно иметь цепочку исключений с фактическим номером строки.

На самом деле нет трассировки стека? Вот что я получу, если запустил spring-boot-school-timethibited с недопустимым constraints.drl:

Что ясно говорит о номере строки Line 1:0 mismatched input 'go'. Как воспроизвести ваш случай?

В основном я хотел посмотреть, есть ли способ увидеть вывод ошибки, с которым я знаком. Я могу работать с выводом как есть. Спасибо за ответ. - person elk-tamer; 18.03.2021
