Создание файлов JAR, проблема EntityManagerFactory - PullRequest
0 голосов
/ 27 декабря 2018

У меня в проекте 2 модуля: demo и db.Я использовал maven и intellij.Демо-модуль Spring.Когда я сгенерировал jar-файлы («чистая установка», «package») и запустил демонстрационный jar-файл («java -jar demo-0.0.1-SNAPSHOT.jar»), программа обрывается на

EntityManagerFactory emf = Persistence.createEntityManagerFactory("database");
EntityManager em = emf.createEntityManager();

Исключение:

когда я запустил приложение отладкой, все работает.

Когда я комментирую две строки, программа EntityMenagerFactory работает.
